Sometimes our clients think about the safety of their property and home, and come to the conclusion that they need install a lock on a metal door!
This measure may be due to the fact that there is only one lock on the door, or the locks are old and unreliable. Often, when purchasing an apartment from a developer, you receive a useless, cheap door with one unburglar-resistant lock. In this case it would be logical install an additional lock on the entrance iron door to secure the apartment.
Before installing a new lock, you should first decide on its type. Locks can be level, cylinder, and others. The type of key that you will have to carry in your bag or pocket is also different. You can read about the types of locks in our article. And the types of keys are described in this article.
So, we will describe the step-by-step installation of a lock into a metal door using the example of a lever mortise lock. Guardian (Border, Crit, Mettam, Senate, Elbor and many others) without a handle mechanism.
Step 1: Decide on the type of lock to install
Figure 1 shows mortise lever lock with a lever key. This is a common type of lock, and they differ in price depending on the additional security mechanisms. These can be an armored plate on the body (against drilling of the lock), pins inside the bolts, anti-pick systems, and so on. Many companies produce such locks, but we recommend installing Guardian, Crit, Border- these are high-quality locks with a guarantee from the manufacturer that will last a long time on your door.
Figure 2 shows mortise cylinder lock: it has a number of advantages and disadvantages, but in general it is also a good option for inserting into the front door if you combine it with an armor plate for the “larva”.
In Figure 3 level rim lock- such locks are placed on old steel doors, and their entire body is visible.
Step 2: Measure your dimensions
Before installing the lock, measure the dimensions of the lock body, its width and height.
The cut in the door will have to be made taking into account these dimensions, adding 5-8 mm of “reserve” to them so that the body can easily fit into the hole, but at the same time the overlay decorative strip will have to cover all the irregularities and cuts, so too large gaps cannot be left either .
Mark the dimensions on the door with a white stationery corrector or marker; if necessary, they can be easily erased with alcohol.
Step 3: Cutting out a seat for the lock
Cut a hole for the lock. It is best to make a longitudinal cut with a grinder; the cut should be made deep, since sometimes there are two layers of metal in the door body.
Step 4: Drilling
After the cut is made, it is necessary to drill a series of holes at the top and bottom of the intended groove for the lock. Since it will not be possible to get there carefully with a grinder, due to the large diameter of the circle, it is better to drill holes. Once you've drilled into the metal, you can carefully knock it out with a heavy-duty screwdriver and hammer, or break it off with pliers or pliers.
Steps 5-6: Measuring seat depth, keyhole
After cutting the hole for the lock, you should try it on in the seat, and also measure the distance from the end plate to the center of the keyhole. This is necessary in order to drill a hole in the door on both sides for a key. It is important to measure the distance accurately because... You can ruin the MDF panel inside the door by missing the height or length of the required hole.
After you have drilled the hole, insert the lock again and look through the gap - the center of the drilled hole should coincide with the center of the keyhole. if so, you can move on to the next step.
Step 7-8: Drilling Key Holes
After “trying on” you can start drilling for the keyhole. Similar to Step 4, make several holes in the longitudinal plane with a margin of 3-4 mm at the edges so that the key fits freely into this hole without clinging to anything.
It is important not to go beyond the boundaries of the future decorative cover for the keyhole, which comes in the box complete with the lock. After all, a damaged door will not look beautiful, and it will be difficult to restore the metal.
The holes are drilled from the outside with a metal drill, and from the inside (if the door is lined with wood or an MDF panel) - with wood drills.
Steps 9-10: Installing the lock in the door, attaching the linings
After we have made all the necessary holes, we can begin attaching the lock and pads to the keyhole.
The lock can be secured with metal screws or rivets. It is more advisable to use self-tapping screws if the metal of the door is thick, and there will be somewhere for the self-tapping screw to “catch”. If the metal is not very thick, it is better to “rivet” the lock.
When attaching the linings, it is important to maintain the ideal horizontal position of the key when entering the lock. Shifts up, down, and to the sides are dangerous because the lock may jam further!
Steps 11-12: Mating holes, drilling, measuring.
After the lock is installed, it is necessary to drill holes for the bolts on the mating part of the door frame. It is important to accurately measure the depth and diameter of these holes, because if you “miss”, the door will either not close at all (the bolts rest against the metal), or vice versa - the door will hang even when closed, due to too large holes.
For an accurate hit, you can smear the lock bolt with putty or any other white mixture, and then, with the door closed, “knock” the bolts on the counterpart using a key. This way, traces of the crossbars will be imprinted on the door frame, and you will know exactly where to drill. Large holes are made either with large diameter drills or with a step drill, as in the picture.
Done, the lock is installed!

Installing a lock is not the easiest type of work; it requires a competent approach. Therefore, for those who may not be able to cope on their own, it is better to call a professional. And whoever is ready to install a lock on their iron entrance door can use the information about the installation procedure in our article.
Types of castles
In order for the doors to perform their main function, it is worth placing an appropriate lock on the entrance metal leaf. Which one to choose will depend on a number of factors. Please note that not all locking devices are suitable for metal panels. They should be selected based on the thickness of the structure.
Models based on installation principle:
- The invoice is the simplest type of lock, since the main mechanism is located on the outside;
- Mortise - installed inside the canvas, in a pre-cut hole;
- Inset - installation is carried out by the manufacturer, so independent installation is excluded due to its complexity and the need to completely disassemble the door leaf.
Before installing a lock, you need to pay attention to the burglary resistance class. It is recommended to install devices of categories 3 and 4 on an iron door. They have the highest degree of protection. Locks with weak protection are placed where it does not play a special role. If the packaging does not indicate information about the protection class, then it is better not to buy such a lock.
Popular models of locking devices include:
- Level ones;
- Cylinder;
- Electronic;
- Level ones.
The castle is called a level lock due to the sulvades, which are presented in the form of steel plates. When opening the door with the key, they become in accordance with the order established by the manufacturer. The degree of reliability will depend on the number of plates, the quality of the material used for their manufacture, and the presence of an armored insert.
It is not easy to knock out such a lock if you strike the keyhole with your foot or hand. But, if you want, you can actually open the mechanism by selecting a unlocking device.
For greater security, it is recommended to install two locks of different designs at the same time on the door.
Cylinder
The most popular types of locks include cylinder models, which have good burglary protection. They have rods with specific imprints, keys with counter grooves in them.
Such locks have a high degree of security, but it is not difficult to break them using brute force. It is worth taking those devices that have an armored insert and a high degree of protection. If the key is lost, there is no need to change the entire lock, only the internal part will need to be replaced.
Electronic
Locks are interesting due to their novelty, design and high cost. They are opened using a magnetic card, by entering a code number on the panel or using the remote control.
Advanced models are opened using a fingerprint and scanning the retina.
Before buying a lock, you should consult with knowledgeable people and consider options for popular models, taking into account all the nuances of operation.
It is better to buy one good and expensive lock than two cheap, low quality ones. If you buy a budget model, you may encounter problems during operation. You should not install three locks on the door, but one will not be enough to ensure security.
Installation Tools
Installing a lock into the canvas yourself is not so easy. In addition to knowledge of the installation process, experience with tools is required. It is also important to follow safety guidelines.
During the work, you cannot do without a drill, grinder, hammer, metal drills, screwdriver, square, tape measure, coarse stone to sharpen the drill. Using it you can expand the landing area in the door under the lock.
When using electric tools, it is important to avoid the risk of electric shock. It is necessary to use special protection, only high-quality tools and extension cords.
How to install a mortise lock
To install a lock, first of all, you should make holes in the structure both for the hole and handle, and for the internal fittings. It is first necessary to correctly determine the placement of all elements.
The procedure for inserting into a metal door structure is carried out as follows. Using a tape measure and a pencil, the location of the mechanism is outlined. Basically, the height of its placement ranges from 100 to 150 cm.
The edge of the recess is marked in the door leaf. Using a drill, drill along the edges of the hole, then use a grinder to cut out the inside. Uneven areas along the edges are filed using a file. To avoid displacement of the drill, the marks should first be worked out using a core.
A lock is mounted inside the canvas and the location of the fasteners is noted. Using these marks, an opening for the screws is drilled, and the thread is cut using a tap.
The location of the exits under the lock is established, the handle lever is on both sides. The lock is placed on the door and the points are marked. Next, large holes are drilled, and all the parts are attached to the iron entrance door.
The operation of the lock is checked. During normal operation, the handle is then installed and the cover panel is screwed on. The core is lubricated, the crossbars are turned a couple of times.
On the reverse side, using a grinder, holes are drilled on the box for the lock bolts. The plate is fastened from above.
Installation procedure for a rim lock
A slightly different procedure is carried out if you need to install an overhead lock. In this case, the mechanism is placed on the surface of the door. It is important to securely fix the lock, bring the reverse part out and create conditions for blocking the bolts on the mating part.
To install a lock on an iron entrance door, the mechanism is initially applied to the door leaf and markings are made. It is noted where there will be holes for fastenings, pins, and the well exit.
Models of overhead locks are positioned slightly higher compared to mortise mechanisms. The height of the latch should be comfortable when used.
Then fastening fonts are placed on the metal sheet. Where the marks were previously marked, holes are drilled for their exit to the outer part of the canvas. A rim lock is attached to the pins on the room side.
The crossbars are fixed with an overhead strip. It should be screwed from the reverse side to the door frame. Holes are drilled in the frame and threads are cut. The panel is secured with screws.
Precise adherence to the location of the counter part in relation to the main lock is required. Otherwise, the crossbars will not fit into the recesses that are intended for them.
In some overhead-type models, standard recesses are cut out in the box with a counter plate. In this case, the box should protrude to the level of the lock.
Installing a mechanism on a metal entrance door is not so difficult if you know all the installation nuances and have the necessary tools.
The need to insert a lock into a metal door may arise for various reasons, for example, you purchased a new entrance door or decided to update an old locking mechanism. If you do it yourself, you can save money, but if the work is done poorly, there is a risk that the mechanism will quickly break down or your home will be broken into. Let's figure out what you should pay attention to in order to avoid mistakes.
The technology for installing a lock on a metal door can vary significantly depending on the type of locking mechanism
Required Tools
Doing such an important job with your own hands is actually not that easy. In addition to knowledge of the features and installation technology of locking fittings, skills in working with various tools will also be required. In addition, it is important to follow safety precautions when working with them.
To install a lock into a metal door, you may need the following tools:
- drill;
- set of drills;
- core for metal;
- tape measure and pencil;
- self-tapping screws and self-tapping screws;
- screwdriver;
- screwdriver;
- file;
- thread tap;
- Bulgarian.
The necessary set of tools for installing a lock on a metal door
When using power tools, it is very important to ensure that there is no risk of electric shock. Use special protection and use only high-quality tools and extension cords.
Be sure to take care to protect your face from sparks and iron filings.
Lock selection
In order for the door to perform its functions, it is important to install a suitable lock on the entrance structure. The choice depends on many factors. First of all, it should be borne in mind that not every lock can be installed on an iron door. It must be selected for the specific thickness of the product.
It is also necessary to distinguish between models according to the installation principle:
- Invoices. Installing a rim lock is the simplest option, since the main part of the mechanism is located outside.
- Mortise. The lock must be inserted into the body of the canvas, having previously cut out part of the material.
- Built-in. These models are installed at the door production stage, and therefore they are practically not installed with your own hands, since to do this you need to completely disassemble the door leaf.
Types of door locks depending on the installation method
Systems are also distinguished by degree of reliability, level of secrecy and type of mechanism:
- cylinder;
- level;
- crossbars;
- disk;
- electronic;
- magnetic.
The first two types are most often used. The principle of their installation as a whole is not much different, but in some points there are significant differences. Let us consider in more detail the stages of work on installing mortise and overhead models in an iron door. The most popular today are mortise models, so you should start with them.
Installation technology for a mortise model
In order to install a mortise lock on the front door, it is necessary to make not only holes in the door leaf for the hole and handle, but also to deepen the mechanism inside. The work will not be easy, and it is also important to accurately determine the position of all fasteners and external outlets.
Installing a mortise lock model is a rather labor-intensive process for a beginner
How to properly embed a lock into a metal door with your own hands:
- Mark the position of the lock using a tape measure and pencil. Usually the height ranges from 100-150 cm.
- At the end of the canvas, mark the boundary of the recess. Using a drill, drill holes along the edges, and then cut out the inside with a grinder. File the edges to remove any rough edges or nicks. To ensure that the drill does not move, you must first work out the marks with a core.
- Insert the lock inside the canvas and mark the position of the fasteners. According to these marks, drill holes for the screws and cut the threads using a tap.
- Next, you need to determine the location of the keyhole exits and the handle lever on both sides of the door. Attach the lock to the canvas and make marks. Then drill large enough holes and secure all the pieces in place.
- Check the operation of the mechanism. If everything is in order, install the handle and screw the cover panel. Lubricate the core and rotate the bolts several times.
- On the opposite side of the box you need to cut it out with a grinder or drill holes for the lock bolts. A counter plate is attached to the top.
Since intermediate manipulations can lead to movement of the lock, check the functioning of the mechanism after each operation. Identified problems must be corrected immediately.
Installation of a rim lock
The installation of a rim lock is performed slightly differently. Here the main part of the mechanism is located above the canvas, and not in its inner section. It is important to ensure reliable fixation of the lock on the surface, bring its reverse part out and create conditions for locking the bolts on the mating part.
How to install a rim lock on a metal front door with your own hands:
- To begin, attach the lock to the canvas and make markings. It is necessary to note the position of the holes for fastenings, pins, well exit, etc. Please take into account that overhead models are usually placed higher than mortise ones, that is, at a comfortable level for using the latch.
- Install the mounting pins on the metal door.
- Using the previously made marks, drill a hole for the well exit to the outside of the door.
- Attach the overhead mechanism to the pins on the room side.
- Check the operation of the lock and, if everything is in order, screw the housing onto the blade. An overlay is mounted on the reverse side.
- An overhead block is used to fix the crossbars. It is screwed onto the opposite side of the box. To do this, drill holes in the frame and cut the threads. Then tighten the panel with screws. It is important to maintain the exact location of the counter part relative to the main lock. Otherwise, the crossbars will not fit into the recesses intended for them.
- In some overhead models, you can cut standard recesses in the box with a counter plate. To do this, one condition must be met: the box must protrude to the level of the lock. This mainly applies to wooden structures, but metal models can also be designed in this way.
If you are sure that the task does not present any difficulties for you, get to work. If you lack knowledge and skills, it is better not to undertake such a complex installation and entrust this work to the masters.
The need to install a lock into iron doors yourself can arise in two cases - when the door is made by hand and when, for security reasons, there is a need to install an additional lock. In both cases, there is no need to rush to call a specialist - perhaps you can master this process yourself. We’ll talk about it in this article, in which, together with the site, we’ll look at the question of how to install a lock on a metal door? We will understand the sequence of work, and also study the subtleties and nuances of this process.

Installing a lock on a metal door: necessary tools
Before we begin to study the actual technology of inserting a lock into a metal door, first we will understand the tool that will be needed to carry out this process. In principle, nothing extraordinary is required here, and in most cases such tools are available in the kit of almost every home craftsman.
- Drill and drill bits for metal. In addition to small drills, you will also need large drills with a diameter of 12 to 18 mm. This tool with all its equipment is, in fact, the main tapping tool.
- In addition to drills of various diameters, it would also be a good idea to purchase a small coarse-grained sharpening stone for a drill - with its help it is very convenient to remove burrs and, if necessary, expand holes in.
- An angle grinder, which is popularly called a “grinder” - you won’t be able to do without it, since with its help you will have to cut a mounting hole in the metal frame of the doors. In general, a drill and an angle grinder can be called universal tools that simply must be in the arsenal of any home craftsman - there are a lot of attachments for these tools, with which you can perform a lot of various operations. I say this to the effect that if such tools are not available, then it is better not to ask friends for them, but simply purchase them, especially since today there are a lot of inexpensive household models.
And, of course, in order to get into a metal door, you cannot do without such hand-held auxiliary tools as pliers, screwdrivers, a hammer, a tape measure, a square and other little things, without which, in principle, no housework can be done. Even if we are talking about simply changing the lock on a metal door, you still cannot do without these tools.
This video shows how to insert a lock into a metal door.
How to put a lock on a metal door: sequence and nuances of work
The technology itself for installing a lock on a metal door is not complicated; the main difficulties arise only due to the material itself - metal, you see, is a durable material, and not every person has the patience to work with it. In principle, this is not a problem if you choose the right approach to the matter - which is what we will do now, having studied in detail the technology of lock insertion. Let us present it point by point for a better understanding of the essence of the issue.
- Marking. Everything here is quite simple - as a rule, it is installed at a height of 800-900mm from the bottom edge of the door leaf. At this point, mark the center of the door end and the length of the hole to be cut, which should be slightly longer than the length of the lock. Along the edges of this hole (bottom and top), on the central marking line, using a hammer and a core, we make small dents for drilling holes.
- Drilling. There shouldn’t be any difficulties here either, since the most important thing here is to choose the right drill diameter. It should be slightly (a couple of millimeters) larger than the thickness of the lock. We just take it and drill holes.
How to install a lock on a metal door photo
- Cutting a hole for the lock. To begin with, you can make markings - connect the edges of the drilled holes with lines, thus indicating the cutting orientation. In principle, if you have experience in cutting metal, then you can do without markings. Now we take a grinder (preferably a small one) and make two cuts - as a result of your efforts, the middle should fall out, forming an oblong hole. There is one small nuance here, which fully depends on the material from which the door frame is made - a problem may arise with a profile pipe. In this case, the hole will have to be cut on both sides - a small grinder allows you to do this perfectly.
- Next, in order to embed the lock into a metal door, you will need to drill a hole underneath - you need to start this work with markings. Using a tape measure, calculate the distance from the edge of the lock to the keyhole and transfer it to the door. Also at this stage of work, you can simultaneously mark the hole for the handle square. You need to start drilling a hole for the lock by drawing its contours, and then drilling a lot of small holes along the resulting perimeter. The closer you can get them to each other, the better. After the holes are ready, using the same drill, only working with it like a milling cutter, we combine them all into a single slot - then we take out a piece of metal and try on the lock with the cylinder. If necessary, we bore this hole using a drill and a small abrasive wheel until the cylinder fits freely into the lock.
- Drilling a hole for . Everything here is generally simple - if the markings were carried out accurately, then all that is required here is simply to drill a hole of the required diameter.
- Installing a lock. When all the holes in the door leaf are ready, you can start assembling - this stage of work is also not difficult. To begin with, we install the lock itself - we simply insert it into the slot at the end of the door leaf and fasten it with metal screws or, if the kit includes screws, then with them. Next, we insert the cylinder and connect it to the lock using a long screw - it is inserted from the end of the door. For these purposes, a special hole is provided in the lock. After the screw is tightened, we check the functionality of the lock, and if everything is fine, then we move on to the next stage of work, which involves answering the question: how to install a lock on a metal door?
- . We will not describe this technology in detail - you can read about how to install a handle on the front door in another article on our website. Here I will say only one thing - it is easy to install, and the most complicated thing you have to do here is drill small holes for self-tapping screws.

The final stage of work related to solving the issue of installing a lock in a metal door is the manufacture of a counter hole in the door frame, which includes the bolt of the lock and latch. In principle, the matter is not very complicated, but it requires precise markings. The easiest way to mark the necessary holes is to put a strike plate on the lock bolts and mark its location almost with the doors closed. After this, as they say, it’s a matter of technique - we re-apply the strip to the box, specifically mark the location of all the holes and use a drill to drill them out.
Some craftsmen prefer to cut one continuous hole - naturally, it is much easier to do it with a grinder and, most importantly, accuracy is not particularly important here. With this approach to the matter, another problem arises - if the rail is not installed accurately enough, then the doors will either not be locked at all, or will begin to dangle. In general, in such a situation you cannot do without adjustment, which takes quite a lot of time. Although in the previous case there is also an adjustment, it is much easier to do - a drill and a drill of a larger diameter solve all the problems.
That's basically it. Now decide how difficult it is for you to install a lock on a metal door. Yes, it is not easy, you will have to overcome some difficulties in the process, but, in general, it is quite possible to do this work yourself. I will say more, even the most qualified specialist once learned this process and made the same mistakes that you are about to make. There is no need to be afraid of this - as they say, he who does nothing makes no mistakes!
Situations often arise when you need to install a lock on a metal front door. This is necessary if it is made by yourself; you need to embed a second locking mechanism for greater protection. The easiest way to do this is to call a special service department, but in most cases, installing a lock on a metal door is not so difficult, so the installation can be done on your own. This will save you some money.
Selecting and purchasing a locking mechanism, one or two, is the first step in installing it. Locks differ in their class of resistance to burglary; the higher the category, the greater the protection the mechanism guarantees and the longer the attackers will have to tinker with it.
For an apartment or country house, it is worth acquiring locks of resistance class 3 or 4; products of lower categories (1 or 2) are suitable only for utility rooms.
If a product does not have a burglary resistance class indicated, you should not buy it.
It is possible to install locks on the iron entrance doortwo types:
- Cylinder. They are widespread. Their design includes pins of a specific shape, as well as a key with recesses for them. This type of lock has a disk code mechanism. Despite its complexity, the larva of such a device can be damaged quite easily - knocked out. Therefore, it is worth purchasing premium products that have an armor plate. It protects the mask from being knocked out.
- Level ones. They got their name because of the plates (levers). When the lock opens, they line up in a clear order. The greater the number of levers, the more reliable the lock (its protection class is higher). Armored plates are also installed in such locks.
Since each type has its own specifics and disadvantages, the best option is to install two locks with different mechanisms in a metal door. This will ensure the maximum degree of property protection. But the whole process takes quite a long time. In this case, a specialist will help solve the problem. The technician will install locks on a metal door quickly and efficiently.
In addition to mechanical locking mechanisms, electronic locks are installed in iron doors. They open using a remote control, a magnetic card, and the most modern models respond to a fingerprint.
According to the installation method, locks on an iron door are divided into the following categories:
- Invoices. Almost the entire lock is located outside the sash. Installing it is quite simple on your own.
- Mortise. The most common option. To install a lock on an iron door, a hole is cut out in the door leaf. Externally, this is the best option, since the lock is not visible.
- Built-in. The insertion of locks into an iron door is carried out into the leaf during the assembly stage of the product at the factory. Replacing or installing such a lock on your own is quite problematic; you will have to completely disassemble the sash.
- Mounted. This type is not used for residential premises; it is suitable only for change houses or outbuildings. To mount it on a metal sheet, lugs are welded.
You should not buy cheap products, otherwise you will have to spend money later on repairing or replacing them. It is better to purchase one high-quality and expensive lock with a high level of protection than two cheap and easy to open ones. In addition, cheap mechanisms begin to jam after a short period of operation. That is, you will again need to put a lock on the entrance metal door.
But you shouldn’t go to the other extreme and install as many locking mechanisms into the canvas as possible. Cutting into each element gradually weakens the sash. Therefore, experts do not recommend installing more than 2 locks. For maximum protection, it is better to install two doors to the apartment (entrance and vestibule).
Preparing tools
To insert a new lock on a metal door or replace an old one if it breaks, you don’t need complex tools. You will need a grinder, a drill and a screwdriver. For the drill, you should purchase drills of 12 -18 mm in diameter. It is also good to have a coarse-grained sharpening stone so that, if necessary, you can easily expand the technological holes and polish them, removing roughness.
You also need a file, screwdrivers, and a tap for threading. For marking, you should prepare a tape measure and a pencil. From fastening elements it is necessary to make a supply of screws and self-tapping screws. That's the whole set, it can be found in every owner's home.
The difficulty of installing a door lock on a metal door is that you will have to work with metal of considerable thickness and strength. For overhead and mortise locks, the method of installation is slightly different.
When carrying out any repair work, you must not forget about your safety. Therefore, it is better to work in protective gloves, and wear goggles when cutting metal.
Mortise lock installation diagram
To insert a lock into an iron door, you will need to drill several holes: they are needed for the handles, the mechanism itself, and also for the well.
Inserting a lock into an iron entrance dooris performed in the following sequence:
- Mark the location of the lock. The most convenient height for its installation is from 1 to 1.5 m. You can also place the lock at a distance of 80 or 90 cm from the floor.
- In the end area of the sash, mark the edges of the groove. Make small indentations at each end of the marking made with a drill, then between them you will need to make a notch using a grinder. To prevent the drill from “driving” on the metal, you can first make light dents with a core and a hammer. For drilling, it is important to choose a drill of appropriate diameter; it should be 2 mm larger than the thickness of the lock.
- Cut a hole for the lock. Connect the drilled edges with lines. Now you have to work with a grinder; it is better to use a small tool. If the door is made of profile, then you will need to cut a hole on both sides. A small grinder is perfect for this type of work. After making the hole, be sure to file the edges so that they are even.
- Make a hole for the lock cylinder. At the next stage of inserting the lock into the entrance metal door, it is necessary to calculate the distance from the well to the edge of the device and transfer the markings to the door. Also at this stage you need to make markings in order to install the door handles later. It is best to draw the outline of the castle on the canvas, and make small holes with small pitches along its perimeter, which are then connected into a single whole. After the slot is made, remove the metal, insert the lock (try it on), if necessary, bore the hole to the required dimensions. This can be done with a drill equipped with a small abrasive wheel. The cylinder should fit well into the lock.
- Make holes for fixing the handles. It's simple: just drill holes of the required diameter.
- Place the mechanism in the door leaf body and mark the points for its attachment. For the fixing screws, make holes, then use taps to form threads in them.
- Install the lock. Insert the iron door lock (into the prepared slot), fasten it with screws or self-tapping screws. Often fasteners are included with the device. Then install the cylinder and connect it to the lock. To do this, you will need a long screw that is inserted from the end.
- After tightening the screws, check whether the lock works properly. If everything is in order, install the door handles and trim. Lubricate the core with machine oil or other lubricant, check how the crossbars work.
- Now you need to make a counter hole in the box into which the latch and bolt will fit. First make the markings, you need to do this as accurately as possible. You can hang a counterplane on the bolts of the lock, cover (close) the sash as much as possible and in this position mark the edges of the striker. Drill appropriate recesses in the door frame for the crossbars. Record the answer.
To prevent any shifts from occurring, you need to regularly check the functionality of the mechanism as you install the lock.
After inserting the lock into a metal door, for normal operation of the mechanism, it is important to periodically clean it from dust and dirt and lubricate the mechanism. New products already contain lubricant, but those that have worked for several months require maintenance. To lubricate the crossbars, you need to extend them to the maximum, distribute the lubricant over them, and push them back. After 40 seconds, repeat this procedure again. Do this 3 or 4 times. Also, for normal operation of the locks, do not allow the sash to sag. To do this, you need to adjust the hinges and correct their operation, select canopies that are suitable for the weight of the canvas.
Installation procedure for a rim lock
This type of lock is easier to install, since the main part is located on the sash, and not in the middle.
To install a lock on a metal entrance door, you will need to perform the following steps:
- Attach the lock to the sash, make marks for its fastening, the hole and all other elements. Locking devices of this type are usually installed higher than mortise ones. This is done so that the latch can be used more conveniently.
- Mount pins for fastening on a metal sheet.
- According to the markings, make a hole for the well to exit to the outer side of the sash. Secure the rim lock using the pins from inside the room.
- Check how accurately the mechanism works. If there are no problems, finally fix its body on the sash. Install a trim on the outside of the door.
- Make a recess in the box, make a thread, and install an overhead block. It is necessary to fix the crossbars. It is important to do everything correctly, otherwise the crossbars will not fit into the corresponding recesses.
You can install a lock on an overhead-type metal door yourself without any special skills. This is much easier to do than to cut it in. The process itself takes a little time.
Replacing a cylinder lock
Installing locks on a metal entrance door equipped with a cylinder mechanism is very common, since in the event of a breakdown there is no need to insert a new lock. It is enough to replace only its damaged larva.
The core is made in the form of a cylinder; updating such a device is not at all difficult.
- First you need to remove the spent larva.
- After this, using a special key you need to open the mechanism. There is no need to remove any other elements of the lock.
- From the end side, unscrew the screws that secure the lock plate.
- Using the key, close the device. Unscrew the screw in the center of the tongue.
- Turn the key 40 degrees and pull the cylinder upward.
If the lock core is damaged, you will have to drill it out and then knock it out of the mechanism.
Replacing a lever-type lock
There are a lot of manufacturers of lever locks, but when choosing them, you should give preference to European brands, since they are much easier to repair. If such a device fails, then its spent core must be replaced.
To install a lock of this type in a metal door, it is necessary to dismantle the existing housing. To do this, open the door so that the crossbar elements are visible. Then remove the lock core. You need to remove the armor plate, deadbolt, handle and key. There is no need to remove decorative elements.
After this, unscrew the fixing screws and remove the old part. Then install a new core and secure it. In some cases, it is not necessary to replace the lock element, and for better operation it is enough to simply recode the mechanism using a special key and instructions that come with the product.
Features of an electromagnetic lock
These types of devices differ significantly from lever and cylinder devices. They include two parts - the main and counter plates.
Inserting a lock into a metal doorconsists of several stages:
- The first step, as in the case of any similar work, is marking the installation site. First you need to attach the body to the door leaf. Glue the stencil in the place where the response plate will be located. After this, mark the points where the fasteners will be installed.
- At the next stage, you will need to drill holes of a suitable size for them. Fix the plate on the metal sheet using special washers. To ensure sufficient strength, you need to install a pair of washers on each screw. The steel washer is screwed on first, then the rubber one. This ensures a tight fit of the core.
- Select the location where the corner of the device will be located. Combine the main part with the anchor element. Use a hexagon for fixation.
- To check the correct installation, slightly loosen the fixing bolt. This will release the counter plate.
After this, you can connect the power supply and check how well the lock works. The main condition is the correspondence of the plate and the base. If the parts are displaced in any way, the mechanism will not work. To make it easier to install a lock on an iron entrance door, you should first study the instructions for it and watch a training video.
