How to install a lock on a metal door yourself. How to install a lock on a metal door: step-by-step instructions. How to install a lock on a door

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-proof 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!

The locksmith will arrive at a convenient time and, if necessary, select and buy the lock you need, taking into account your wishes and budget.

Installing a lock on a metal door is not as simple as it might seem at first glance; such work requires a competent and meticulous approach. Installing locks on metal doors involves inserting a locking structure (cylinder or lever). Today we will look at a few simple rules on how to embed a lock into a metal door, look in detail at the installation procedure and find out what the most common mistakes craftsmen make when carrying out this kind of work. But first, let's find out what types of locks there are and how to choose them.

Types of castles

There is the following classification of door locks.

Cylinder (English) locks

They are distinguished by high security and difficulty of opening; their mechanism is designed in such a way that the cylindrical part will turn only with a key of the correct shape. By the way, today it is English locks that are most popular due to their reliability and low price.

Plate locks (level locks)

This design consists of plates that have characteristic shaped cuts; when opened, they are pushed out from the protrusions on the key. But lever locks are not highly reliable, since due to the wide keyhole, master keys can easily enter it.

Electronic locks

This is the crown of technological progress to date. A smart lock cannot be broken, and only the owner can open it using a special plastic card, key fob, or after entering a password from his smartphone. The obvious disadvantages of the newfangled gadget include its rather high cost.

It is important to know: according to their reliability, locks are divided into classes, and the higher the class, the more reliable the lock. Also, when choosing a lock, be patient and before you go shopping, first decide what exactly you want to purchase.

Principle of choosing a lock

Study the lock you are thinking of buying well: pay attention to the manufacturer’s reputation, customer reviews on thematic forums. Remember, price is not the first indicator of quality.

Don't skimp on your purchase. Of course, locks are not cheap, but remember the main rule of the British - we are too poor to buy cheap things (it is better to buy one high-quality lock for many years than 2 cheap ones). Also, inexpensive locks are quite easy to open; in addition, they are sometimes inconvenient to use due to the jamming of the mechanism.

If you want to secure your apartment, then install 2 locks, but always with different opening mechanisms.

Installation of locks in metal doors occurs as follows: first of all, one type of lock structure is inserted (from above), and then below - the second. Remember: you cannot install more than 2 locks, as this leads to a weakening of the rigidity of the metal door. As practice shows, cylindrical locks are the best at preventing burglary from mechanical locks.

Also, when purchasing, pay special attention to the design of the keyhole and the possibility of opening it. For example, a cylindrical well can be easily knocked out, and a leveled one can be easily aligned. Therefore, in order to make it impossible to find a master key for your lock, buy only those locks that have good security characteristics and reputation.

How to install a lock on a door?

To install a lock on a metal door you will need:

1. Now we place the lock itself in the metal door and secure it.
2. Having attached the lining to the door, we mark those places on the door where the fastenings for them will be made.

The escutcheon is a special metal plate, the purpose of which is to hold the lock in its original position and prevent it from becoming loose after a certain amount of time. The linings must be secured on both sides and checked how well the key turns in the hole (if the keys are tight, this means that the linings fit too tightly to the lock and they should be slightly loosened, unscrew them, and then screw them back).

The next stage of installing locks on a metal door is installing the bolt.

The bolt is a special mechanism that closes the door. The holes for it need to be marked especially carefully, since this determines how tightly the lock will snap into place, and they can be made using a regular grinder. So, the installation work is completely finished and all we have to do is check the readiness of the structure for work.

A little life hack: if you smear chalk on the deadbolt, insert it into the lock and turn it with the key, then ready-made marks will remain on the door.

Conclusion

This brings our lock installation to its logical conclusion. As you already understand, installing a lock on a metal door is not the easiest or fastest process, since it is necessary to take into account all the subtleties and nuances of the work, take correct measurements and cut out all the necessary holes so that they fit the lock exactly. The choice of mechanism is also important. Before purchasing, decide what is more important to you: a high-quality item that will serve you for many years and will reliably protect your home or unnecessary savings, which can backfire, so to speak. Remember: a high-quality lock is not only more reliable, but also easier to install and operate.

In many apartments, owners install metal entrance doors. They better protect housing from intrusion by unauthorized persons. But the locks in them are weak, so there is a need to install a new locking mechanism on a door of a different type. The need to put a lock on a metal door may arise for other reasons.

When purchasing metal doors, losing the keys, or wanting to install a new lock on the door of a better model, you have to look for it in stores. It is not recommended to buy a cheap mechanism and door leaf made in China. Experienced experts advise choosing products from Spanish, Israeli and Italian manufacturers. They are distinguished by high quality, reliability and long service life.

Products are divided depending on the type of mechanism, level of secrecy and degree of reliability into:

• level;
• cylinder;
• disk;
• crossbars;
• magnetic;
• electronic.

Most often, door locks are installed with lever and cylindrical mechanisms.

Good locks are produced by the Russian companies Polivektor, Gerion and Elbor. Products must have an additional handle. It fixes the door leaf in the closed position. It is better to purchase models with lever and cylinder mechanisms. When installing locks on metal doors, it is necessary to take into account the thickness of the door leaf. In terms of reliability, you should choose products of the third, or even better, second class.

There are several categories of door locking mechanisms. They are usually divided into 4 classes. The highest quality ones belong to safety class 3-4. They also cost more. First class products are the easiest to hack. The second and third classes are of medium reliability. They can be used at home. It is better to install a lock in a metal structure of the fourth or third security class.

Locks come in mortise and overhead locks. Do-it-yourself mortise structures are inserted into metal doors. Leveling mechanisms provide reliable protection of the apartment from the penetration of uninvited guests. The operating principle is based on the presence of iron plates in the mechanism. Each plate has special shaped cutouts. The degree of reliability of the device depends on the number of cutouts.

Cylinder models of products are very popular. They consist of pins equipped with springs. This type of lock is most often inserted into an iron door. A failed core can be replaced. The most secure and reliable door locks are coded ones. They are installed in office doors. The code set and magnetic reading device ensure high reliability and quality of the lock.

How to install a lock on a metal door?

Fitting locks into a metal door is a difficult and responsible task. It can be handled by a person who knows how to handle measuring and electrical tools and has experience working with metal. All operations are carried out with great care and precision. The work consists of separate stages.

The first stage involves preparing the necessary tools. The next stage is choosing the location of the mechanism: it is located 1 m from the floor level. You can raise it to a level of 1.5 m. At this distance, the body of the mechanism is leaned against the end of the blade and the insertion points are marked. Now you need to take a drill, the diameter of which is equal to the thickness of the lock, and drill holes on the upper and lower boundaries of the device. Using a grinder, a hole is cut exactly according to the markings. The edges are processed with a file.

The main stage involves inserting the housing into the resulting groove. To do this, you need to mark the locations for the mounting screws. They are drilled with a drill of the appropriate diameter and the thread is cut with a tap. Using a grinder and a drill, large holes are made for the keyhole and handle on both sides of the door leaf. After that, the mechanism is finally inserted into the groove and fixed with screws. The lock and all its parts are driven several times with keys to check the quality of the work performed.

After the main steps, you need to mark and install the overlays. The crossbars are rubbed with chalk and tightly close the door leaf. With the help of a key, the crossbars are moved so that traces of chalk remain. They will show where to drill holes for the crossbars. A counter plate is installed on top. After each operation performed, you need to check the operation of the mechanism.

The overhead lock is installed less frequently. This is done a little differently. The mechanism of the device is located above the door leaf. It must be well fixed on the surface of the canvas. All work is carried out in the following order:

• The lock is applied to the canvas for marking.
• Mounting pins are installed.
• Through holes are drilled for the well.
• The mechanism is fixed on the installed pins and its operation is checked.
• The lock is finally fixed on the canvas.
• An overlay is attached to the reverse side.
• The crossbar fixation block is screwed to the opposite side of the door frame.

If you are not afraid of the listed conditions for installing constipation, you can get to work. If there is a lack of skills and knowledge, the best way out is to entrust the work to specialists.

In conclusion, it is worth citing advice from experienced people and craftsmen who professionally install locking devices on doors.

1. A high-quality lock is an excellent protection for your apartment from uninvited guests. But along with it, you should not give up other methods of protection: video surveillance, alarms, etc.
2. When installing the mechanism, you should check its operation at each stage of marking and installation. Any violation in marking and drilling holes can completely disrupt the operation of an expensive locking device.
3. The installed mechanism must be constantly monitored. It needs to be lubricated periodically, as the old coating gradually loses its properties.
4. The crossbars are treated with liquid compounds in the maximum extended state. After this, you need to push them back to their original position for 30-45 seconds. The procedure is repeated 3-4 times.

Before purchasing a product, you should follow the selection rules:

• expensive, but a high-quality lock is better than 2 cheap ones;
• 1 constipation is not enough, 3 is too much;
• It is better to install 2 different types of devices on the door;
• a cheap model is an extra headache.

Embedding a lock into a door leaf is not a difficult task. But only a knowledgeable person with experience can install a lock on a metal door. When installing, you need to take into account the thickness of the metal sheet on the canvas. Otherwise, you can damage both the lock and the door itself. And this will lead to higher cash costs. It is better to entrust this task to professional workers.

A metal door can not only protect you and your family from break-ins, but will also become an excellent watchman and guard for your property. This condition can only be met if the correct and reliable lock is selected for the door leaf.

There are several types of locks for metal doors: cylinder and lever, according to the orientation of the invoice and mortise. The safest locks for entrance doors are mortise locks, since it is much more difficult to break into or pick up the key to such a lock.

Lever locks are more reliable, but require more effort during installation and replacement, since each bolt must fit perfectly into the hole. Cylinder locks are easier to replace since, as a rule, only the cylinder needs to be replaced, but they are less secure. Ideally, it is best to install 2 locks on the door - a lever and a cylinder!

Installing a lock on a metal door with your own hands - why?

When purchasing an entrance door from a manufacturer based on your order, you can choose a lock that is offered to you with a high security class, and in this case, relocating the lock yourself is required in rare cases. However, when purchasing a factory-made Chinese door, as a rule, the locks on them are not of high quality and security, so when purchasing such a model, it is better to change the locks to more reliable ones.

Before buying a lock and hiring a professional who will install the lock, you should read the step-by-step instructions to understand that installing a lock on a metal door yourself does not present any difficulties if you have the appropriate tool. The process itself may only take you a couple of hours and the biggest difficulty is working with metal, which is a fairly complex material.

Installing a lock on a metal door with your own hands, like any other work, involves a number of specific steps that should be followed during the installation process.

Before starting installation, you need to prepare your workplace and tools:

• Grinder - you can’t do without it, since in order to insert a lock it will be necessary to cut certain holes in the metal;
• Drill - It is best to use an electric drill, as cutting holes in the metal for the bolts is an activity that requires a lot of force.
• A hacksaw, which may be necessary when cutting holes for the lock;
• Of course, the lock itself, which must be selected from the list of a huge assortment on the market;

The assortment on the Russian market includes a large number of locks for metal doors, including those made in Russia and Italy. In order to choose the lock you need based on security class and other indicators, it is best to consult with a specialist who can tell you all the pros and cons of the model. When choosing, do not base your choice solely on size, number of crossbars, or cost!

• Metal screws, angle, ruler, punch and other locksmith tools that can be useful when installing a mortise lock in a metal entrance door with your own hands.

In principle, we can say that almost every man who has at least once carried out some plumbing work on his own or has been involved in repair work in the house has these tools. You need to start installing a mortise lock on a metal door by removing the old lock from the hole in the door leaf. After this, you can begin installing the new lock.

Step-by-step installation of a lock into a metal door

1. To begin, attach the new lock to the canvas and draw all the markings of the lock. The location of the crossbars, the length and height of the lock, the place for screwing the screws. For marking, it is best to use chalk or a metal marker.
2. Once you have marked where the mortise lock will be located, you can start drilling. The hole where the lock will be inserted should be slightly larger than the lock itself.
3. After inserting the lock into the drilled niche, it is necessary to fix the lock in the door to the strips and to the door leaf using metal screws.
4. Installation of the upper closing strip, which will hide the lock and fix it in the door leaf. If the hole for the lock is much larger than the length and width of the lock, then over time the screws may become loose and it will begin to dangle, and one day the bolts may simply become warped and you will not be able to get into the house. Therefore, it is very important to make accurate markings when cutting into the lock.
5. Holes for the crossbars are drilled in the box with a drill. From 3 to 6, as a rule, these holes are made with a drill attachment slightly larger than the diameter of the crossbars.

Features of installing a cylinder lock yourself

There are some special features when installing a cylinder lock in a metal door. For each cylinder and closing system, a separate hole is required, which is drilled with a drill and processed with a grinder when cutting off unnecessary parts of the door. After the cylinder is immersed in the hole, a closing armor plate is also placed and a hole is drilled in the box that will secure the locking mechanism.

Thus, installing a lock on a metal door is not such a complicated process that may require the presence of a specialist for installation. Installing a lock on the door yourself is a guarantee of your safety, since the entire process will be controlled by you personally. When installing a lock on a metal door, remember that high-quality installation can guarantee a long service life for the entire door.

A person who has experience working with metal can insert a new lock into a metal door himself. The process of installing a new lock is quite labor-intensive and complicated, and it can take a lot of time and effort. Plus, such activity is not safe.

It will be useful for real men, accustomed to solving such problems without outside help, to read our advice before starting work on installing a lock on a metal door.

What tools will you need for installation?

• Do not start working with power tools that are not completely safe. It is highly advisable to use dielectric gloves and not neglect the use of safety glasses. Check the carrying case for connecting power tools - their power must be appropriate.

• designate a specific location for installing the lock;
• the insertion location is planned according to the dimensions of the lock body;
• To secure the upper and lower boundaries of the cutout, drill two small holes. To do this, use a large diameter drill to fix the required width. Remember that the centers of the holes need to be punched before you start drilling;
• in order to make two cuts, take a cutting grinder wheel and cut according to the marking lines, from the top drill to the bottom. If such a need arises, you can expand the finished opening for the lock. An angle grinder is suitable for this;
• when the lock is already in a suitable place, you can begin to mark the exact location of the holes for the screws;
• if the holes for the screws are drilled and the thread is cut (the diameter of the hole for the M4 thread should be 3.8 mm), then you can insert a lock;



• Now you need to pull out the lock and start marking the key spaces. Markings must be applied on both sides of the metal door. Take a grinder to drill and cut the holes for the keyhole;
• When the lock is installed in the appropriate location, secure it with screws. Next, check if there are any difficulties turning the key in the lock;
