How to make a rack lock with your own hands. Secret lock

For thieves, neither a lock with a secret, nor a high fence are an obstacle. However, sometimes homemade locks can be more of a problem for them than purchased factory products. In ancient times, in villages and even in cities, the doors to houses were not locked. But in our time you have to lock everything and everywhere. To protect the home, and sometimes the garage, not like locks, even expensive alarms are installed.

It would seem that on sale there are as many different locking devices, latches, bolts, locks with many secrets. Why do we need homemade locks? Firstly, it is hardly possible to pick up keys for such locks, because they are made in a single copy, and drawings for them cannot be found either in the literature or on the Internet. Secondly, inventing and making locking devices with your own hands is a very exciting activity for many home craftsmen.

How to do it yourself? According to the masters, almost everyone can make a gate. Described below, in their opinion, is the most convenient and reliable way of locking a double-leaf gate.

The advantage of such a pinwheel lock is that the gate can only be locked from the inside. There are no keyholes on the outer surface, and on the inside, the lock is a metal bar that pivots on a pin. This latch rises and falls into metal grooves screwed to both garage door leaves.

Such a turntable closes and opens without much effort. Its main drawback is that the gate must have an additional door. But it already has to be locked. If the garage is attached to a residential building and there is an entrance to it from the house, then such a constipation is the most reliable and economical thing.

Also, it can be locked from the inside using pins bent with the letter "L". They rotate in a bracket welded to each edge of the door leaf - top and bottom.

For the upper locks, an emphasis is made in the form of a small horizontal metal plate so that the pin does not fall down under its own weight. The lower pins simply stick into the ground or into holes specially made in the garage floor. Such locks for garage doors are quite reliable and available in manufacture.

Locks of our own production

With your own hands, you can make not only bolts, but also garage locks. For example, the description and drawings of how to make or gates were published back in 1998 in No. 6 of the magazine "SAM". Until now, this design is very popular among garage owners. It is being improved and even made "code".

"Coding" a padlock is done by making notches on the key and adjusting the number of half-turns to close the lock. Of course, an attacker will be able to pick the code length and number of turns. But this operation will take too long. He probably won't want to mess with the lock for more than a couple of minutes.

Another type of homemade locks that are often used to lock garages is the screw lock. He locks the garage door with a screw in the latch tube. The key to it must match the bolt head. The problem is that the key itself is very large, and it is very easy to pick it up with a round brass nozzle.

One craftsman came up with the idea of \u200b\u200bmaking a freely rotating screw cap. It only engages with the screw when the original T-slot wrench is used. The master makes such screw locks with original keys to order, earning good money on this. Homemade electromechanical locks are not often used by garage owners. Although it is more reliable than all those described above.

The principle of operation of such a lock is quite simple. When the door, wicket or gate is closed, the cocking bolt of the lock presses on the spring inside it and the tongue enters the groove of the door - the so-called counterpart of the lock. This is a purely mechanical device. The electronic part of the lock (in most cases it is a solenoid - an inductance coil) acts on the bolt, closing or opening the electrical network.

An electromechanical lock usually has an electronic key in the form of a tablet or is controlled remotely from a key fob. To make such a lock with your own hands, they use an ordinary massive lever lock, from which they take out the levers (plates with turnkey figured cutouts), leaving only the crossbars. A guide plate is attached to them. As an electric drive for such a lock, drives for car locks are used.

A device such as an electromechanical lock is quite expensive. Another disadvantage is the inability to control it in the absence of electricity in the garage. In order to protect oneself from the inability to open such a lock, a car alarm connected to the car battery is used for power supply.

The garage is that secret place where every man can spend a lot of time. But on top of that, there is an expensive thing stored there - a car. Many people save up some money in order to buy a suitable car for themselves. Therefore, in the first place after the purchase is the reliable protection of your "treasure". That is why you need to hang a reliable and durable lock on the garage, which no one will be able to open or break. Among the many purchased locks, there are homemade garage secret locks that are reliable and more secure.

What is the advantage of homemade locks? The fact that they are more difficult to open. If the attackers are already familiar with the standard locks that many buy in stores, then a barrier with their own hands with modifications can stop the robbers. This is what our article is about. We will consider some of the secrets of garage locks, their types and features. We will also learn how to make a homemade garage lock with our own hands.

Effective Garage Security Lock Secrets

The secret in the lock is the secret so that no one knows its structure. The main task is to make the structure of the lock complex, but at the same time simple at first glance, the secret should not be easy to read with indirect signs. There is some regularity here. It lies in the fact that simplicity is the key to success. The simpler the lock appears, the more difficult it will be for an attacker to crack it and understand how it works.

Since these are homemade garage locks, their variety is quite large. However, among the large number of very different designs, there are several cereals that can be canceled:

Note! In order for your secret lock to remain so in the future, it is important to ensure that strangers do not see how you open or close the garage door. Otherwise, the principle of its work and the very essence of the work will be lost. The trick will fail.

Secret locks, which work on the basis of a simple car alarm, have a similar disadvantage. Why can I say so? Because any car alarm has a standard device and mechanisms. That is why a professional needs at least one look at the keychain or signaling box, mechanism and wires to determine the implementation of the secret. Let's take a closer look at some of the available secret lock schemes, and then try to put it all into practice.

Some schemes of locks with a secret

First, let's consider the mechanical types of the secret for the lock. They boil down to the modernization of an existing castle. Here's what you can do to protect your garage from thieves:

Simple screw lock with a secret

Now we can consider homemade screw locks for the garage. They are very popular because they are not difficult to create and they are quite effective. In order to create them, you need the ability to use the machine. Then you can get a screw lock with a secret, which you see in the photo below.

Its principle of operation and the secret lies in the fact that the key head has a special configuration. To create a more complex screw-type lock system, you need to make two degrees of protection and two keys. This will make the design even more reliable. To understand how this product works, we suggest you watch this video:

As you can see, garage protection is very reliable. Nowadays, replicas of old mechanical locks with a secret are gaining popularity. The secret of its functioning comes down to a very complex key shape. This means that it is very difficult to make for yourself the same shape of the work surface without having the original. However, it is hardly rational to use it for garage doors.

Padlock with a secret

If we talk about modern analogues of the structure of the ancient castle, which was discussed above, then these are simple hinged structures for garages. We are all used to seeing them. Below in the photo there are drawings of similar structures.

The body of the product has bushings with pins in the amount of 2 pcs. and a retaining ring. They block the movement of the mechanism. The loop can be removed when you have been able to correctly position the pin. When the mechanism turns, the groove in the cylindrical part of the pin begins to align with the corresponding hole in the housing. Then the end of the bow can be released or blocked. In the case when there is one pin on the lock, then it is not so difficult to choose the desired position on the case.

If you make two pins that have their own individual groove arrangement, then it will be very difficult and time-consuming to find the right position. In addition, when closing the garage, you can easily turn the pin to any position to keep secret in which state the lock can be opened.

An example of creating a lock with a secret with your own hands

Now let's look at how you can make a simple lock with a secret with your own hands. The first option will be to create a special key and locking structures. To create it, you need to have the skills of a welder in order to perform a number of welding works.

The construction itself is very simple. On the garage door of one half, on the reverse side, you need to weld on hinges, in which a locking mechanism in the form of a metal plate will be installed. On the other half, the same loops are welded into which the locking plates will enter. It is important to place them on the same level so that movement is smooth. A hole is made in the plate itself, thanks to which the owner can close or open the garage. The whole secret is in the key for such a lock. It will be made of thick wire, with a special shape and length. It will allow you to push the key into the hole in the gate, and then open or bury the locking mechanism. All holes are made identical to the wire diameter.

The bottom line is that there can be several such plates. And the secret comes down to the fact that there is no lock or structure on the gate, only a hole. An attacker will not be able to pick up the key, understand how to open the gate, because he does not see the exact distance from the hole to the plate. A key 1 or 0.5 cm larger / smaller will not be able to open this door. To understand how everything works visually, you can watch this: homemade garage secret locks video.

Advice! To prevent the attacker from guessing how to open this lock, you can disguise the hole, and hang an ordinary old lock next to it, which does not work. This will distract him for a long time, and he will not be able to get inside in any way.

You need to understand what the purpose of a lock with a secret is: it must confuse the intruder. It is in the originality and originality that the whole power of the design. If they have learned to cope with ordinary constipation, then this is something new, unrecognized. The more you can upgrade the product, the better.

Let's sum up

Garage protection is a major concern for every car owner. And if thieves have learned to bypass standard purchased items, it's time to show imagination and make your own cunning and unusual lock with a secret. With him, you can definitely be sure that no one will encroach on your property. And thanks to visual videos, you can make similar designs with your own hands.

Often, a purchased lock with a conventional installation method is not reliable, so many car owners try to make an original model of a homemade garage lock with their own hands.

This is an easy way to ensure yourself a restful sleep, because the garage and the property inside it will be protected from intruders. How to make the locking mechanism yourself, what is needed for this, this article will tell.

The issue of protecting a garage building from intruders is always acute, and especially for those people who drive a brand new car of a prestigious brand. Scammers are trying to get just such cars in order to resell them further. A home-made lock with a secret will help protect the motorhome from the penetration of strangers.

Such products are distinguished by a simple design; a special key will help to open them. It is extremely difficult to pick up a master key for opening a homemade locking mechanism, because it is created according to an individual sketch. It is this quality that is the most important advantage of such mechanisms.

The installation of self-made garage locks, made by hand, is carried out from inside the building. For this reason, the locking mechanism is completely invisible to the eye of a stranger. Under such conditions, even an inveterate burglar can hesitate or even change his mind to penetrate inside the structure, because this will require a lot of time and effort from him.

The process of making homemade garage locks with your own hands is worth starting if you have high-quality materials at hand, you have access to steel hardening, a lathe, a milling machine. Then it is worth constructing a really durable, reliable screw lock.

With a certain kind of skill, you can even create an electric lock. But if such skills are not enough, you can go the other way. It is worth remaking the finished product by modernizing it in a certain way.

Completion of purchased locks

If there is no actual material at hand, a lathe, you can make an attempt to modify the finished locking mechanism with your own hands in the garage.

But before starting work, it is worth figuring out what types of such units exist. Consider the classification of products according to the specifics of installation, presented in the table.

Padlock for garage doors.

Let's describe the ways to improve each type:

1. Hinged. It is optimal to supplement a gate with such a locking mechanism with another lock made by yourself. A hidden electric lock will do. You can retrofit a conventional one-pin attachment by adding another pin with an individual groove position.
2. Overhead. To prevent the risks of burglary, it is worth supplementing the unit with an electrical circuit and a servo mechanism. The mechanism will only work if the key is turned inside the lock or is opened using the remote control. The system will look like a car alarm.
3. Mortise. You can modify the cylinder of such a lock so that the key is unique. Then it will be difficult to pick up a master key for hacking. Another way to modernize a mortise lock is to lengthen its bolt.

On a note! When converting, it is important to take into account the features of a particular type, so as not to break it, but to strengthen the protective qualities of the locking mechanism.

At first glance, locks created by the hands of craftsmen will certainly turn out to be of high quality. But many of them are too simple, defenseless against burglars. For example, a rack and pinion locking mechanism with a "secret" key is not really a quality product.

The highlight of the mechanism is considered to be the turning bar on the key, the length of which is "kept secret." Yes, the burglar does not know the length of this part, but he may well be able to make its cardboard counterpart, which will then trim it until the machine starts to crumple it. The next time he comes, the thief will already open the garage, take everything valuable from it.

Practical example

Many car owners do not understand how to make a good locking mechanism with their own hands from a finished product of low reliability. Let's describe a practical example of car protection for little money. It is suitable for a motorhome that is close to the cottage and opens from the house.

The garage door must only be locked from the inside. Build one of the homemade garage secret locks for them. The power of the bolt should be veiled so that a stranger, when looking at an open door, does not understand which element is holding the gate. From the side of the water gate, it will be possible to enter the motorhome only with the help of a ramming truck.

A separate door inside the house, through which the car owner enters the motorhome, is equipped with an internal and regular lock. Internal is a solenoid type electric lock with the ability to control it from home. If the doors are closed with a regular lock, the solenoid will also close.

Homemade lock device.

Hacking a regular machine with a master key will prevent thieves from entering the motorhome. Before leaving the cottage, the residents of the cottage will open the electric lock by supplying power to it, and this will unblock the gate, after which they will open the usual lock.

Electric locks for the garage should be installed so that it attracts as little attention as possible. The solenoid assembly is often powered by 24 V, several amperes when triggered, and even less current to hold open.

You can equip the electric lock with a latch with an electromagnetic control method. Or prefer an electromagnetic model with a chamfered bolt, which fixes them when the gate is closed.

To prevent a homemade garage lock with a falling bolt and key from freezing in winter, its body is heated. Wrap the unit with fiberglass, wrap with nichrome wire, 0.3-0.5 mm thick. Select the length of the wire so that the heating of the solenoid at room temperature reaches 70 degrees.

The voltage source will be the same as for powering the solenoids. Next, cover the nichrome wire with a layer of fiberglass, a tin cover. Nichrome and copper wires are connected by welding, neatly brought out.

On winter days, it is enough to carry out heating a few minutes before opening the gate for the units to work flawlessly. As a result, you will get a cunning castle, which will not be easy to eliminate.

Outcome

Making a garage lock with your own hands will allow you to get reliable guarantees that an attacker will bypass the motorhome. It is much more difficult to crack such garage doors, since the homemade product is unique in its parameters.

In the article we will talk about how to make locks for a garage or for outbuildings on our own. As a rule, locks that are used in garages or outbuildings are made using simple designs. They are opened using special keys. Due to the fact that they are installed indoors, this makes them as invisible as possible. The manufacture of such locks is carried out individually, taking into account all the wishes and capabilities of the owner.

It is quite difficult to pick up master keys for such locks, this is the main advantage when compared with standard models. We will look at what homemade locks are for use in garages and outbuildings, and also talk about their differences from those copies that are sold in stores and markets.

Features and varieties of homemade castle designs

A garage is necessary in order to protect a car or any other vehicle from external factors, including theft. As you can imagine, with the help of a garage, you protect your car from the effects of precipitation and other natural phenomena. But there is no complete guarantee of the safety of your vehicle. To a greater extent, the safety of the car depends on how strong and reliable the lock is.

There are several types of garage locks:

• Hinged.
• Mortise.
• Overhead.
• Rack and pinion.
• Mixed devices.

The main criterion that distinguishes these devices from the rest is the manufacturing method. But there are both factory modifications and homemade ones. We will talk about the latter in as much detail as possible. After all, homemade garage locks are increasingly being used due to the fact that they are very reliable and more difficult to open.

What to look for

If you decide to purchase a factory copy, then you need to determine its quality. Very often the price tells about the quality of the product. If you want to purchase a quality and reliable device, you will have to fork out and spend quite a lot of money.

The fact is that in this case, the lock will not be made using stamping, as is done in most cases. It will be assembled by hand by professionals. There are several points that will distinguish products assembled at the factory from homemade products. As a rule, handicraft second-rate homemade products have a rather low quality, hence we can talk about the low reliability of the structure.

If you decide to make your own castle, you will lose in quality - this is indisputable. And this, first of all, will be reflected in the safety of the vehicle. Installation of the lock is a very important step, it must be approached very responsibly. When you need to consider one point. Normal protection will be provided only by the mechanism that is not striking, or it is not visible at all.

Principles of operation of padlocks

Such designs are most common, the entire mechanism is located in a suspended case. In homemade padlocks, locking is carried out using a pin or other similar elements. They are inserted into the mechanism. In order for the structure to work, it is necessary to install special eyelets on the doors that are planned to be locked. An arc is installed in them, which, in fact, produces locking. But this design option has one very big drawback, which completely negates all its positive qualities.

Such a lock can be broken very easily. The fact is that such designs of locks are installed from the outside of the building. Therefore, any attacker has direct access to it. Using a pick or grinder, you can easily open such a homemade garage lock. Most often, locks of this type are used for additional protection when a combination occurs. In other words, several mechanisms are used to lock the garage.

Rack homemade locks

Such locks are also quite popular, they have one advantage. They are mounted exclusively inside garage doors. Locking takes place using several sliding rods. The lock is opened using an individual key, which is installed in the well.

When you turn it, the latches are pulled out. The design of the lock is a little more reliable, but still, if desired, it can be opened without problems. For this, the locking elements are simply sawed, or a key is selected.

Mortise locks

This design has several disadvantages at once. First, it has very low reliability. Secondly, it is very difficult to mount it. The use of such structures is allowed only as an additional measure of protection. It is very difficult to make such a structure on your own. Therefore, it is better to give preference to a different mechanism for locking doors. We will talk about them further.

Homemade constructions

It is very common to find spinners for locking garage doors. They work like a deadbolt. The design is simple, you can do the installation yourself. The principle of operation is as follows:

• On the inner side of the gate, it is necessary to mount the eyelets; they can be made from both metal and wood.
• A spinner must be installed in the center of the gate with a through bolt. It will be set in motion by turning around the center.
• The ends of the turntable must fit into the lugs. This is how they lock the doors as securely as possible from the inside.

At the same time, there are absolutely no parts of the castle outside. It is almost impossible to crack this structure, so its reliability is very high.

Espagnolette

This is the simplest design, reliable and efficient. Ideal for locking garage doors. Therefore, it can be used in most cases. But let's find out, This is a metal pin that moves inside the special lugs. As a rule, it is installed on the inside of the sash. This device functions as a gate valve.

Locks for swing gates

This is a kind of latch, but there is a slight difference. Espagnolettes, as a rule, move in a horizontal plane, they are usually used if the gate has one wing. If the gates are swing gates, then the elements are made of metal rods that move vertically in the eyes. These lugs are installed on the sashes. In order to lock the door as securely as possible, holes must be made under the metal rods in the ground. They should be larger in diameter than the pins.

In order to increase the reliability and strength of the entire structure, it is necessary to install metal tubes of a suitable diameter in the holes. After installation, it is advisable to concrete them. But such constipation has one drawback. They can only be closed from the inside, so an additional door will need to be installed. Typically, these locks are used if the garage is attached to the house, or is located in the yard.

How to make a castle yourself

Now let's look at a simple instruction for making an invoice system with a valve. It must be set in motion using a special homemade key.

The design consists of the following elements (consider at the same time their manufacture):

1. First, the base of the castle is made. It is a metal plate, it is advisable to use it with a thickness of at least 3 mm. Plate diameter 10 mm.
2. It is also necessary to cut two overlays from similar metal: 22 mm wide and 120 mm long.
3. Next, you need to bend these pads in a vice.
4. After that, you need to make a valve.
5. Make a guide tube, the outer diameter should be about 1 cm. The key of the lock should subsequently enter into it. The length of this tube depends on how thick the gate is. The end of the tube must be cut at a 60 degree angle.
6. At the first stage of assembly, it is necessary to weld the pads on the edges of the base. If suddenly there was a deformation of the elements after welding, they need to be straightened. If the curvature is small, then it can be corrected.

At the corners of the plate, 4 holes must be drilled, with the help of which the lock will be fixed to the sash. Install the guide tube into the hole in the plate. As a result, you should have a relatively cheap and simple homemade lock with a "secret".

The bevel must be directed towards the linings. After that, you can weld the tube to the base, but do not forget that these elements must be perpendicular. Next, you need to install the lining and valve. Two bolts with a diameter M4 must be screwed into the valve. The length of the bolts should be about 8 mm. These screws will limit the valve travel. It is recommended to install spring washers under their heads so that they do not unscrew when the lock is operating.

Key for a lock with a "secret"

As a key, you must use a rod with a circular cross-section, the diameter of which is 8 mm. The length should be about 15 cm. This is the optimal value. As you understand, making a homemade garage lock with your own hands is half of the "trouble"; you will also need to make a "tricky" key.

It is necessary to bend one edge at a right angle, this will be the handle that you will hold when opening. On the other side, you need to make a cut at an angle of about 60 degrees. A hole must be drilled near this cut. Next, make a groove. After that, collect the key for the homemade lock with your own hands.

The secrecy of this design is ensured by the fact that turnkey holes are drilled in the valve, while there can be an interval of 1 mm and more. This will provide the castle with the greatest number of privacy options. Similar homemade door locks are commonly used in warehouses, outbuildings and garages.

How to make DIY garage locks

Garage doors are two leaves, one of which has a wicket. The leaves are closed with bolts, latches, hooks and other latches from the inside. The entrance to the garage is through a wicket, therefore, a locking device is installed in it.

In the article we will analyze their types, distinctive features and installation methods.

Types of locks for garage doors and their characteristics

To date, the following types of garage locks are presented on the building materials market:

• rack and pinion;
• mortise;
• (cylindrical and lever).

Almost each of the proposed locks has both significant advantages and disadvantages in the process of installation and use.

Rack lock

It is a traditional design that was used by most garage owners even before the advent of improved models. To open the gate, you need to put the key into the well and, due to the significant power load, push it inside.

The only advantage of this type of locks is strength and durability. Otherwise, they are quite inconvenient to use, since they require a lot of effort during operation and are simple enough for burglars, therefore, they will not fully ensure the safety of the garage object.

The padlock

Is the good old fashioned way of closing a garage. The lock is installed by welding special hinges to the sash. Such systems are considered to be fairly reliable and easy to use, and also able to provide protection against hacking.

The disadvantage is that the device is outside, so an attacker can easily knock down or cut down the lock, which means that there is no need to talk about one hundred percent safety of the garage. There are better and more expensive hardened steel models on the market, which guarantee a greater degree of stability.

Mortise lock

It is fastened to the core of the gate and has a rather laborious installation procedure. Like the previous versions, even this type of lock is not able to guarantee one hundred percent protection against intruders.

Overhead option

Installed on the inside of garage doors and locked with a deadbolt. Moreover, its most common types:

• Cylinder system reliably protects against all kinds of picks, since it has a code system. However, if desired, this structure can be cut down.
• Lever locking device - this is the guarantor of the protection of the garage object and is considered the safest lock. It is distinguished by the presence of protective armor plates, a myriad of key combinations, large size and high strength, which eliminates the possibility of cutting down or breaking the constipation.

We design a homemade castle

There are several typical types of locking devices that you can design yourself. These include:

• spinner;
• latch;
• lock for swing gates;
• lock with a falling key.

Simple constipation, popularly called "spinner", is often used for double-leaf gates of garages and other buildings. This type of constipation is easy to construct with your own hands. The advantages of this lock include strength and ease of use.

For work, you will need wood bars about 50 millimeters thick and metal strips.

The way the "turntable" works is extremely simple - the crossbar is placed in the center by means of a through bolt. It moves along the wedge-shaped bars. In the process of closing, the sashes rest against the door block closely to each other, no additional bolts are required. There are no details of the castle from the street, so breaking it is not possible. Thus, the outside of the garage is reliably protected, and from the inside it is easy to open it with one movement of the hand.

Often a simple bolt is installed for constipation. Installing it does not take much time and effort. But there is one drawback - the shutters do not fit tightly to each other, so there may be a small space between them. For the rest, this design, although simple, is quite reliable in operation.

A latch is a metal rod with a stop that moves in a structure specially equipped for this. The espagnolette can be bought or welded with your own hands.

One of the most common designs is a simple bolt made of a metal strip that moves into a welded metal loop. These hinges are installed along the edges of the sash. Also, a tongue is installed on one side of the gate, which will fit snugly into the second loop. In order to ensure the reliability of the system, it is important to provide a stopperwhich will serve a dual purpose. Thus, the bolt can be made in a short time without much effort.

Swing gate lock

These are sliding attachments that are welded to the frame. Before installation, it is important to decide on the location and number of locks. If the gate has two leaves, these structures will need two pieces, one for each side.

A mark is made at the place where the constipation will be located, and the place where the metal rod will enter the ground is also marked. Then you need to cut two rods of metal of the same length, and small pieces to them. This is so that the bolt can be easily moved.

It is important to consider when determining the length of the rod that it must not only keep the gate closed, but also go quite deep into the ground, which will ensure the reliability of the structure.

For the indentations, you can use a garden drill of a suitable size. And on the frame of the doors, it is necessary to weld several iron rings into which a constipation can be inserted. A small hook can also be welded to support the bolt handle.

Falling key lock

There is another type of clever locking device - the so-called falling key lock. This system is distinguished by a secret - a transverse pin is installed in the lock drum, which is a significant obstacle for lockpicks to crackers. It is impossible to buy such a lock in specialized stores, but there are a lot of self-made people who sell the fruits of their skills. You can also try to make such a device yourself.

In addition to installing the pin in the lock, a corresponding slot is made on the key... This means that any other key, completely identical to the original, will not be able to open the door without such a slot and will run into an obstacle.

First you need to get the locking assembly and push the drum out of its body. Further, in the drum it is necessary to drill a place for the pin perpendicular to the plane of the key being inserted. The drill diameter should be one and a half to two millimeters. After these manipulations, a rod of steel or brass is placed into the through hole. It is important that it fits snugly into the hole. The protruding parts of the rod must be cut off.

As a result of such manipulation, only a key with a longitudinal slot can enter the drum. This lock will reliably resist both ordinary key rings and special master keys made of wire or other material.

When doing homemade work, it is important to remember that the drum is a rather fragile structure, therefore, a thoughtless blow not on the rod, but on the side of the drum can damage the system. And it is most convenient to drill when the key is already in the drum, which will make it easy to make the desired slot.

In addition, such a lock misleads burglars, because such a seemingly inconspicuous and simple device informs the attackers that there is nothing valuable inside, unlike expensive locks.

Installation of a lock on a garage door

When installing conventional locks, difficulties should not arise. But more complex mechanisms require a careful approach and attentiveness to the installation work. If the structure is installed incorrectly, there is a risk of making the lock faulty and unsuitable for further use.

The following materials are required for work:

• metal plate;
• the locking device itself;
• corner made of steel;
• drill;
• screws;
• welding machine.

Installation technique

When the type of lock is selected and the serial number of the keys is checked, you can get to work:

1. The plate, which is the basis for the subsequent installation of the lock, is welded overlapping to the sashes. If the lock is padlock, it is necessary to weld two fasteners on two leaves.
2. On the installed metal plate, it is necessary to make marks in those places where the holes for the fastening screws for fastening the lock will be located. The marks should be carefully drilled.
3. For a hinged structure, you need to buy suitable fasteners where the arc will be threaded.
4. In the doors, you need to cut out places for crossbars and grooves for end fastening. After installing the lock itself, the accuracy and reliability of the fastening is checked.
5. On the outside of the metal sheet, you need to equip a turnkey well that follows the contours of the profile of the lock itself and cut it out.
6. The iron corner will allow you to create additional support for the counterpart, into which the crossbars will enter.

This installation assumes the use of all mounting holes, which will ensure the safety of the lock and protect the garage from the effects of intruders. It is important to remember that the attachment points should not be visible from the street.
