How to install a padlock on a door. Installation of overhead locks. How to choose the right padlock

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:

1. 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.

1. 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 be easily 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.

1. 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:

1. Carefully study the diagram and device of the lock.

1. Choose a place on the door where there are no longitudinal and transverse stiffeners.
2. Attach the lock to the installation site, align, circle the contours and holes for self-tapping screws with a pencil.
3. 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.

1. Using a tap, cut the threads in the channels.
2. Drill a through hole and mount the larva.
3. Install the lock in a regular place with the help of self-tapping screws and a screwdriver, aligning it with the core pin.

1. 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.
2. Drill holes in the box and install the striker plate.
3. 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:

1. Attach the lock to the door leaf and mark the holes.
2. 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.

1. Make a channel for the core by drilling it with a pen of the required diameter.
2. Install the lock on the door leaf, attach to the larva.
3. 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.
4. 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.

It can be as reliable as a good mortise - provided that its cylinder mechanism is embedded in the door leaf. It's easy to do it yourself.

Necessary tools and materials:

• overhead cylinder lock
• ruler
• drill
• hacksaw
• chisel

Process:

1. Using a ruler, mark one third of the height from the top on both sides of the door and drill a guide through hole. If a template is included with the lock, use it to mark the center of the hole.
2. We drill a hole for the cylinder with a chisel drill of the same diameter as the cylinder. In order not to damage the surface of the door, we do it from two sides: as soon as the tip of the drill appears from the opposite side, we remove the drill, turn the door over and finish the job.
3. On the front side of the door, insert the cylinder and the finger bracket (or fixing ring) into the hole. Pressing the mounting plate into place, we check: the connecting rod of the cylinder should protrude 12 mm beyond it. Holding the rod with an adjustable wrench, saw off the excess with a hacksaw.
4. Insert the cylinder with the locking ring or finger bracket into place. We put the mounting plate on the rod and screw it to the cylinder with long screws, making sure that the front edge of the plate is flush with the edge of the door. We drill holes and attach the plate.
5. By pressing the button on the lock body, release the latch and install the lock on the mounting plate, aligning the connecting rod with the slot in the rear side of the lock body. We screw the case to the plate with small screws.
6. Use the button to move the valve to the “closed” position, firmly press the door and mark the position of the top and bottom of the valve tongue on the door frame. Having applied the plate of the locking body according to the marks, we outline its contour with a knife.
7. Holding the chisel at a right angle to the surface (the bevel of the blade is turned inward) and tapping it with a mallet, we will go through the outlined outline. Having made notches inside the contour, we will select wood to the depth of the edge of the plate of the locking body. When choosing the last layer, hold the chisel with the bevel of the blade down.
8. We install the plate of the locking body into the cutout. We close the door and check if the latch of the lock enters the locking case. Deepen the cut if necessary.
9. We drill pilot holes and attach the locking body. The lock is securely installed.

To date, the market offers various types of overhead locks, ranging from the simplest heck 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!

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 degree of protection of any premises largely depends on the quality of the lock, whether it is a commercial office or a shopping and entertainment center or a residential apartment and a private cottage. The entire range of such mechanisms presented on the modern market can be divided into 2 main groups according to the principle of installation - these are mortise and overhead door locks, the price of which varies in a fairly large range.

Both options are equally popular. Therefore, before giving preference to one or another design, be sure to familiarize yourself with all the advantages and disadvantages of each solution, functionality, as well as the scheme for installing a surface and mortise lock. You will learn about all the intricacies of buying and installing locks of the first type from this article.

An overhead door lock is the simplest design. During its installation, it is not required to cut out part of the door leaf, which is one of the indisputable advantages of such a solution. It is installed directly on top of the sash - the main module on the canvas, the counterpart - on the box.

Important! You can open it from the outside with a key, and from the inside - with a special mechanism. Additionally, a variety of latches and wedge latches can be included in the package, which block access to the room, which increases the level of security.
