Overhead door lock: device, diagram, installation. How to install a rim lock Replace a rim lock on a wooden front door
The lock is the main element of the front door. It is he who protects against the penetration of robbers, so his device must be reliable. If you decide to purchase the door leaf and lock separately, or if you need to replace the old mechanism with a new one, then you do not need to call a professional to solve this problem. With such installation, you can handle it yourself. How to do it - read on.
Installing locks on metal doors requires care and accuracy. However, the installation technology is not particularly difficult even for people far from construction. To install a door lock yourself, you need to have a number of tools that are not available in every home. Most of them you can find from friends or rent.
The tool you need to install the lock with your own hands:
- Drill (you can also purchase a screwdriver, but this tool is not required if you have a drill);
- Drills and bits for a screwdriver;
- Core for metal products;
- self-tapping screws;
- screws;
- Roulette;
- File;
- Bulgarian;
- Screwdrivers.
As you can see, there are several expensive electric tools on the list. It will not be possible to insert a lock into the door without their help, so if you could not find them at home or with friends, then it would be cheaper to turn to the master.
We install mortise locks in metal doors
There are mortise and overhead locks. The technology of their installation is very different. The first option is more reliable, such locks are most often equipped with entrance doors.
To correctly determine the place where you can embed the lock, you need to find out where the stiffeners are. These elements are usually arranged diagonally or horizontally.
Installing a mortise lock is more difficult than installing an overhead mechanism. For this option, it is necessary to make holes to deepen the device inside the web.
How to embed a lock in an iron door:
- At the level of a meter from the floor, mark the place where the castle will be located. It is most convenient to mark up with a tape measure and a construction pencil;
- Pencil marks must be punched with a core. This stage is necessary so that when you make holes, the drill does not jump off.
- According to the outline made earlier, drill holes with a drill and cut out the metal inside the workpiece.
- Using a file, remove all bumps and notches from the edges of the hole made.
- Insert the lock into the hole and mark the places where the fasteners will be installed. It is also necessary to determine the location of the keyhole holes and the installation of handles on both sides of the door.
- Marks for fastening the lock are drilled and processed with a tap for threading. Where the handles will be installed and the keyhole is made, sufficiently large holes are drilled.
- Next comes the insertion and fixing of all parts in their places. After that, you need to check whether the mechanism is working correctly.
- If everything is in order, then a handle and a decorative patch panel are installed.
- On the reverse side of the box, holes are drilled for the bolts of the lock, and a counter plate is attached.
As you can see, lock insertion cannot be called a very easy operation. If this is your first time holding construction tools in your hands, then in order not to spoil an expensive door leaf, it is better to entrust such work to a professional craftsman.
We mount a padlock on a metal door
An overhead lock is much easier to mount than a mortise mechanism. However, this option is considered less reliable. If you want to create a high-quality barrier against sudden intrusions into the apartment, then we advise you to install an additional lock.
Installing an overhead code intercom is very different from installing a door lock. Only a well-informed person will cope with such an installation.
Overhead locks are installed at the level of one and a half meters from the floor. This arrangement is necessary for more convenient use of the door chain.
Attaching a padlock to a metal or metal-plastic door:
- The lock is applied to the door at the required level. Mark the places where the holes for installing mounting fonts and for the keyhole will be located. To make it easier for you to outline the desired areas, you can first draw up a layout on paper.
- Holes are drilled with a drill.
- A key guide is installed on the lock body.
- The housing with the guide is fixed with fonts on the door from the side, which is located in the apartment. All slots into which the key will be inserted must match.
- A decorative element for the keyhole is installed on the outside of the door.
- Now it is necessary to turn the key to extend the bolts of the lock. The ends of these elements are smeared with paint and rest against the door frame. A strike plate is mounted at the level of the marks, and holes for locks are drilled.
- The edges of the holes are smoothed with a file.
- The reciprocal bar is installed and the operation of the lock is checked. The crossbars of a properly installed mechanism should freely enter the prepared holes.
Installing a padlock does not take much time. If you are not confident in your abilities, then prepare a design layout on paper, glue it to the door and drill all the necessary holes on it.
How to install a padlock on a wooden door
Installing an overhead locking mechanism on a wooden structure is a fairly simple task. To deal with it, you do not need to purchase a large number of power tools. It is enough just to find a drill with a set of drills and bits for a screwdriver.
With this tool, you can drill all the necessary holes and attach the lock body. For making large holes, you can use a chisel or the same file. The rest of the installation steps of the overhead lock are no different from the technology of its installation on an iron door.
The technology of mounting a padlock on a wooden door is not much different from installing such a mechanism on a metal structure. By the way, it is even easier to work with wooden door blocks.
If you have already installed a lock on a metal door, then you can handle the overlay of such a device on a wooden canvas in no time. However, even people who are faced with the need for self-assembly of an overhead lock for the first time will be able to do such work in a fairly short time.
Installing a padlock on a wooden door (video)
Installing a door lock on metal and wooden doors requires high care and good command of a drill and a grinder. If you are confident in your abilities, then you will save significantly by mounting a mortise or overhead protection against thieves on the door structure yourself. However, if you are not fluent in the tool, then we advise you to abandon this idea and entrust the work to a professional.
The degree of “secrecy” of the mechanism, the quality of its metal and a number of other characteristics do not yet guarantee a high level of protection of the opening from unauthorized entry. Much is determined by how well the locking device is mounted. According to the specifics of the installation, the overhead lock is quite simple, and having delved into some of the nuances of the work, you can not involve a professional.
Fastening is carried out on the canvas, from the side of the room. This is a significant plus, since you don’t have to cut the lock, which means you don’t have to deal with wood sampling. In addition, its position, if necessary, is easy to adjust. But this ease of installation also has a downside - this type of locking mechanism will not provide a high level of security if it is not fixed as securely as possible on the canvas.
It is not difficult to install a padlock on any door, although it is mainly purchased for wooden canvases, since it is more difficult to work with steel. The main technological operations, their sequence are unchanged; the difference is only in the individual tools used in the installation process.
Operating procedure
Location selection
The stage is not the most important, but it should be noted. Even before installation, you need to determine how best to install a patch lock in height on a wooden door. And there are nuances here.
- Competent installation implies that opening the overhead lock should not cause difficulties for any of the family members, even the smallest, who already has his own key.
- The lock is installed in such a way as to ensure maximum security of the door against knocking out. And this is possible if it is located at the level of ½ of the canvas from the nut. At the same time, at least two different types of mechanisms are placed at the entrance. In this case, the lower lock is attached with a distance from the floor of ⅓ of the door height. It happens that there are more of them (3, sometimes 4), and therefore a minimum of a meter is defined for it.
Web marking
- If the location of the lock on the door is known, it is necessary to attach it to it and outline the outline. The body of the lock is positioned so that its cut coincides with the edge of the blade. Since the wood is subject to deformation, besides, over time, some skew of the sash is formed due to the wear of the hinges, it is recommended to make a small indent from the edge (about 2.5 mm). This will not particularly affect the length of the protrusion of the tongue, but it will exclude the possibility of metal touching the box.
- Having received the projection of the overhead device, it is easy to outline the holes for the fasteners and the keyhole.
drilling
Some difficulty in making a hole for the cylinder of the locking mechanism. Especially if a patch lock is installed on a wooden paneled door. It is mounted on its frame, and therefore the accuracy should be maximum, taking into account the small section of the frame beam. In this case, it is recommended to work not with an ordinary cylindrical drill, but with a feather drill or a crown (for wood).
Installation of the overhead device
- Fastening of the mechanism cylinder. It is fixed firmly, since no further manipulations with it are provided.
- Housing installation. It is not necessary to fully tighten the fasteners; it is only necessary to achieve a snug fit of the lock to the canvas.
What concerns the door itself is done. It remains to work with the jamb.
striker fastening
It is placed on the box, from the side of the tongue. To avoid difficulties with opening / closing the overhead lock, incomplete release of the latch or its hook, you need to achieve full coincidence with the slot in the bar. It can be a rectangle or a hole (sometimes two, three); it all depends on the modification of the product. But the procedure is unchanged, especially since the lock on the door is already in place.
- The end of the latch is smeared with paste (ink, ink), after which the canvas is closed. It is enough to turn the overhead mechanism with a key, and an imprint will remain on the box corresponding to the location of the slot in the reciprocal plate.
- The door opens again, and the lock bolt is extended to the maximum length with the key. After the canvas is pressed against the box, their top and bottom are marked on it.
It will not be difficult to determine for yourself how to fix the bar after such marking. You just need to choose the wood to the depth of the latch lunge. How to proceed?
If it is round, then with a drill, but a slightly larger diameter. With a flat tongue of the lock, it is somewhat more difficult. You will have to drill 2 - 3 holes, one above the other. It remains only to knock down the formed jumpers with a chisel and give the notch the desired rectangular shape; the same chisel, shoemaker's knife or other sharp cutting tool.
Putting a door lock on a steel door is more difficult in the sense that you have to process a slot in the metal profile. A file is a bad helper; given the limitation in the "course" of its working part, it will take a lot of time. It is much more convenient and faster to process the recess with a cutter, which is placed in the chuck of an electric / drill.
Health check
No matter how accurately the activities at each stage are carried out, small deviations from the norm are possible. So, you need to make sure that the crossbars move freely, without jamming, to the extreme positions, the latch easily moves from its place, and the canvas fits snugly against the box. Identified defects are eliminated quickly.
It remains to add that the installation of a surface lock on a wooden or metal door should be done after adjusting the position of the sash. If the canopies are adjustable, then it will take a few minutes. With heavy wear of the loops in which there is no such “option”, it is more expedient to change them for new ones.
The door lock can become an impeccable guardian of the premises and the property located in it. A padlock for doors must be reliable and match the material of the leaf on which it is installed. Our article will tell you how to choose the right product and install it.
Choosing a lock by type and features of operation
Among the locks on the market, there are three main types of locking devices:
- Lever locks are considered the most reliable. A set of locking plates (lever) fixes the lock (bolt) in the closed position. Such a lock is opened with a complex curly key, to which it is almost impossible to pick up a master key. The degree of security against opening is determined by the number of levers, in a castle with a high degree of invulnerability there should be at least 6-8 pieces. The disadvantages of lever mechanisms include their bulkiness, large key sizes and the possibility of force hacking due to a wide keyhole. In terms of price and quality, the most popular in the expensive segment are the locks of the Cisa and Mottura brands, in the middle and cheap ones - Cale, PROSAM (Border), Elbor and Guardian. This is the optimal overhead lock for a metal door, garage and other gates.
- Cylinder locks got their name because of the shape of the locking elements in the core (“larva”, “secret”). The more cylinders in the "larva", the higher the resistance to breaking. One or more bolts of the castle are fixed with levers. This common type of locks is easy to install, sufficiently reliable and maintainable. 20 years ago, a cylinder door lock was considered vulnerable, it could easily be opened with a master key or drilling. Modern locking devices have additional protection, keys with side perforation and are equipped with plates made of high-strength materials that cannot be drilled. The simplicity of the design makes it easy to install a patch lock on a wooden door with your own hands.
- Smartlocks are a complex locking mechanism consisting of a mechanical and electronic part. Overhead locks with double protection are considered the most reliable. To open it, it is not enough to have a key. Additional protection is carried out using a digital cipher, reading a barcode from a plastic card, and even a fingerprint scanner. A modern electromechanical overhead lock for the front door will reliably protect your home, office or warehouse. Self-installation will require certain skills, but will not be very difficult.
When choosing a lock for a door, the following criteria should be considered:
- installation location;
- door leaf and frame material.
For interiors and interior doors, light models of overhead locks are suitable. On the front door, you should select a mechanism that is resistant to opening and force breaking.
The strength of the lock must match the material of the door leaf and frame. It is not recommended to install bulky locking mechanisms on wooden, plastic or composite doors. The robber will be able to knock out the door by tearing the lock from its attachment point.
You should not choose one bulky door lock, it is better to install two reliable ones.
The degree of invulnerability of the lock is determined by the amount of time required for unauthorized opening, and the mass of the applied force for breaking. Modern mechanisms cannot be opened in less than 10 minutes, they can withstand loads up to 1000 kg.
Visual instructions for installing rim locks
Mounting a padlock for doors is not difficult. You need to carefully study the instructions and follow the recommendations.
We install a lever lock on a metal door
To work, you will need the following set of tools:
- electric drill;
- drill;
- screwdriver;
- tap;
- self-tapping screws for metal;
- pencil.
Operating procedure:
- Carefully study the diagram and device of the lock.
- Choose a place on the door where there are no longitudinal and transverse stiffeners.
- Attach the lock to the installation site, align, circle the contours and holes for self-tapping screws with a pencil.
- Drill holes for the lock.
The diameter of the drilled channels should be 0.2 mm narrower than the diameter of the self-tapping screws.
- Using a tap, cut the threads in the channels.
- Drill a through hole and mount the larva.
- Install the lock in a regular place with the help of self-tapping screws and a screwdriver, aligning it with the core pin.
- Attach a striker plate to the door frame, align the holes on it with the bolts of the lock. Having chosen a place, mark with a pencil for drilling the fastening channels of the striker plate.
- Drill holes in the box and install the striker plate.
- Check the operation of the installed lock.
The metal door has a large mass. In order to avoid jamming of the crossbars due to the subsidence of the leaf on the hinges, it is necessary to expand the holes on the striker plate by 1-2 mm downwards using an electric drill.
If everything is done correctly, the castle will last for many years.
Installation of a cylinder lock on a wooden door
You will need a few tools to get the job done:
- electric or hand drill with drills;
- screwdriver;
- pencil;
- screws or screws;
- you may need a chisel and a hammer.
Work should begin by studying the scheme.
The installation process itself consists of the following steps:
- Attach the lock to the door leaf and mark the holes.
- Drill holes for self-tapping screws.
The drill should be 1.5-2 mm thinner than screws or self-tapping screws. This will help to securely fix the lock on the wooden door.
- Make a channel for the core by drilling it with a pen of the required diameter.
- Install the lock on the door leaf, attach to the larva.
- Place, without fixing, the fixing bar on the door frame, check the operation of the lock. It often happens that the door leaf and the frame are not in the same plane. To align the lock with the counterpart, it is necessary to deepen the striker seat with a chisel and a hammer.
- When both parts of the lock are aligned, make markings, drill holes and secure the striker plate with screws.
Do-it-yourself smartlock installation
A person who has basic knowledge in electrical and electronics can safely take on the independent installation of an electronic patch lock for doors. Detailed step-by-step instructions are described in the attached video.
A padlock on the front door is an important aspect of the security of a home, office or other premises. A reliable product will ensure safety and add psychological confidence. When choosing a door lock, you cannot save on quality, this can result in big losses.
Anyone can install a padlock with their own hands, the instructions will help overcome apparent difficulties.
To date, the market offers various types of overhead locks, ranging from the simplest latch to overhead cylinder.
In the event that the cylinder mechanism crashes into the door leaf, then such an invoice will be no less reliable than a high-quality mortise one. The quality of the invoice directly depends on the number of pins. If there are at least five in them, then such a lock will rightfully be considered reliable. In addition, all invoices have a stopper and a fixing shutter.
The reliability of fastening the lock to the door frame directly determines its quality. During installation, the lock and its latch are located on the door leaf. In order to increase reliability, the screws with which it is attached must be chosen longer than those that come with the kit, while the diameter of the fasteners must be identical to the standard ones.
Almost all cylinder rim locks are suitable for doors of various sizes. Before installing a padlock, you should check the quality and strength of the door. Otherwise, it can be knocked out.
At the initial stage of installation of the overhead lock, you need to determine its location. If the lock is supplied with instructions, you should use it. As for the height, one third of the height of the door, starting from the bottom, is considered the most optimal. The marked place must be drilled with a chisel-shaped drill. It should be the same diameter as the cylinder. This step must be taken with care so as not to damage the door.
Having received a hole, it is necessary to insert a cylinder and a ring from the front side, which will fix it. Then you need to measure the desired length of the rod. The optimal protrusion outside the interior doors is 12 mm on each side. Excess must be cut off with a hacksaw. Then you need to put a mounting plate on the cylinder and fix it on the surface of the door. The front edge of the plate must be flush with the edge of the door.
At the next stage, you need to fix the lock itself on the plate by pulling out the rod. On the rod you need to put on the back side of the lock, thereby determining its location. At this point, you need to secure it tightly with long screws.
Having determined the position of the locking body using a chisel, it is necessary to cut a groove according to these dimensions. Its depth is determined by the thickness of the locking plate. Then you should firmly fix it.
It must be remembered that the reliability of such a lock is primarily determined by the quality of its installation. Interior doors are usually not equipped with locks, but if necessary, a lock can be installed on them. Basically, internal locks are inserted into the door, they are less visible and they look more aesthetically pleasing. The choice is yours!

Today, locks are installed on the front door of each apartment. And this is not surprising, because any owner wants to feel as secure as possible in his real estate. Security now can only be ensured by a reliable steel door with a good lock. In order to completely eliminate the risk of unauthorized entry into the premises of third parties, most people equip door leafs with overhead locking devices. Let's see what a surface lock is, what types of these devices the market offers, which option is best suited for installation on a metal door.
Areas of use of overhead lock systems
It must be said that devices of this type can be installed not only on the front doors in residential apartments. These are quite popular solutions for mounting on the doors of offices and enterprises. Such versatility of the locking mechanism is determined by the convenience of the process of closing and opening it. In order to open such a lock, you just need to turn the inside of a special latch. But many models can be opened with a key not only from the outside, but also from the inside.
It is believed that such locking systems are ideal for wooden entrance doors - and this is true. The installation of such a device in no way violates the integrity of the door leaf, does not reduce the level of strength and reliability, the leaf is not weakened in any way. In addition, the installation process does not cause any difficulties.
These mechanisms are also installed on metal doors, but there may be some difficulties with them. On inexpensive economy class doors, the manufacturer often does not provide for the installation of additional locking devices. Well, as for all other models, they are equipped with a massive base, therefore, nothing prevents the installation of an additional locking device. This increases the security of the door.
Often, locking mechanisms are already installed on factory models of doors. Many install a padlock as additional protection. This is the optimal solution, in addition, the latch lock will speed up the process of closing and opening.
Device, features, installation
What is an overhead lock can be understood already from its name. Such products differ from the mortise device in that the installation is carried out not inside the web, but outside.
Whichever lock model is chosen, it is best to mount the device from the inside of the door. In this case, the body of the mechanism will be hidden from the eyes of strangers, and possibly intruders. Such locks are usually opened from the outside with the supplied key. From the side of the room, such a mechanism can be opened with a key or with a latch.
Laid on locks of any models are freely installed on wooden doors. Not everyone is suitable for a metal door. The fact is that the design of the locks does not always fully meet the requirements of constipation. This is the presence of a flashing, a small gap, the thickness of the canvas.
On a wooden door, the mechanism is attached with self-tapping screws, but on metal sheets it is necessary to weld pins to a steel sheet and fasten the lock to them using fasteners.
The main types of overhead locks
Today, the modern market provides a lot of different options for overhead locking systems. These are mechanical models, as well as electromechanical and fully electronic.
Mechanical models have the simplest design, which makes them very popular among consumers. The mechanical system of most overhead locking devices is based on the possibility of using keys and a latch. With the help of these elements, you can open or close the door. Electronic equipment works by means of electronic impulses that act on the mechanisms in the lock.
These locking equipment, like everything else, can be classified according to the type of secret system and the number of bolts.
Advantages and disadvantages
Overhead models have a lot of advantages, but they also have disadvantages. Despite minor cons, these products are a good, reliable choice that is comfortable to use.
Among the indisputable advantages, ease of installation can be distinguished - if the manufacturer of the metal door takes care of the users of its products and provides a place for an additional lock, then installation will not be difficult. The whole installation comes down to fixing the mechanism in the place intended for this.
Another plus is the complete absence of even a minimal connection between how well the installation and operation were carried out. Unlike locking devices of other designs, overhead solutions do not allow intruders to loosen the fasteners of the lock.
If it is necessary to repair or service the mechanism of the product, then there are no problems with this either. The mechanism is located accessible and clearly. Installation allows you to significantly increase the level of security of a metal or wooden door leaf.
Now for the disadvantages. Like all existing protective mechanisms, the overhead locking device is not perfect. Even the most highly intelligent locks are broken by professional apartment thieves. As for the shortcomings, the level of their criticality should be decided by the owner of the apartment or cottage himself. When choosing a locking device for a steel door, you should definitely take into account - this can help you avoid wasting money.
The main disadvantage of most overhead solutions is that only a massive mechanism is suitable for installation. This ultimately leads to an increase in the cost of the castle.
If an attacker gets into an apartment or a private house by squeezing out a double-glazed window, then after he collects all the valuables, he will be able to leave the crime scene through the door without any obstacles - the lock can be easily opened from the inside.
If the installation is carried out on a door leaf that opens inward, then for the same thief there will be no problem simply knocking out the locking device. This, of course, significantly reduces the burglary resistance of the door. If the door leaf is equipped only with a rim lock, then it is impossible to replace this mechanism with a device of a different type.
With all their advantages, overhead solutions spoil the appearance of steel doors, because from the side of the dwelling the entire inner surface of the door is visible, and most locks do not have a special aesthetic.
Right choice
If the choice of the locking device and its installation are made correctly, then this is a guarantee that the room is reliably protected from any encroachment. If you do not want to pay a large amount for a locking device, then it is worth remembering that inexpensive models do not have a long service life. Do not buy overly budget overhead locks. Best of all, products of well-known lock brands will serve.
When choosing a lock, it is worth getting acquainted with some important requirements or characteristics that locking devices must meet.
Level of secrecy, reliability
This requirement is due to the presence of locking parts. The more locking pins in the mechanism, the more reliable the lock. If we talk about burglary resistance, then this most often means the ability of a particular model to withstand various mechanical influences.
Most often, when hacking, these effects are forceful: drilling or using master keys by an attacker in the process of opening.
materials
The reliability of the lock depends not only on the super-secure and complex mechanism, but also on the materials from which the product is made. For example, aluminum for the manufacture of locks is not used for obvious reasons.
It is best if the elements of the mechanism are made of cast iron. The main advantage of this alloy is its ability to withstand even severe mechanical stress. But at the same time, cast iron is brittle when exposed to low temperatures.
Steel is the best material for a lock mechanism. It is an ideal alloy with good anti-burglary qualities.
The main types of locks for metal doors
Cylinder pin models or conventional disk products are distinguished by good secrecy. But such locks have problems with burglary resistance - with the help of opening tools, a burglar will need only a few minutes.
Cylinder locks with the ABLOY system are much better in performance. It takes about 10 minutes to open them. The opening process will be accompanied by a lot of noise. These are reliable models and the quality of many domestic or imported products is very high.
Cylinder locks with perforated notches are quite reliable, they are usually made in Italy or in Russia. These models break open with a lot of noise, and in order to open the door, it will take from 30 minutes.
Lever rim locks for metal doors are highly secure solutions that are easy to use in everyday use. It is very difficult to open them even with the help of special equipment, since the master keys needed for hacking are very, very expensive and not all professional burglars have them.
