How to open a padlock with a semicircular key

I once worked as a locksmith, and recently I had to remember the skills to open the lock of a house without a key. The lock turned out to be not particularly advanced and, in general, the work turned out to be quite simple, especially since the necessary tool was in the car. I completed the task and thought it wouldn’t hurt to tell you about the simplest ways to open a padlock without a key. Some will find this useful in case of loss, while others will know how to protect their property. So let's get started.

How to open a padlock without a key?

A simple and logical method is to knock down the lock. With a large hammer or crowbar you can easily rip off the shackle to avoid the need for forced entry. It is enough to saw through the jumper with a metal blade. But this method will not work if the device is made of high-quality steel.

Attention! There are two ways to open a padlock associated with the grooves of the structure. There are several springs inside the device. The bow opens when the springs take a certain position. But this is not a complex program, but the most common mechanics. You can take a teaspoon and rest its handle against the lock, and then hit it hard with a hammer on the other side. The spoon will fit into the nest. After loosening the springs, open the door.

There is a system on disk and combination locks that causes the device to jam when you try to open it. But when making padlocks, the manufacturer does not pay much attention to this. If the locking mechanism is small, then the spoon and hammer can be replaced with a hunting knife.

The socket can be unscrewed. To do this you need a self-tapping screw, a screwdriver and a crowbar. Using a screwdriver, a self-tapping screw is screwed into the lock, leaving the bolt head on the surface. A crowbar is used as a lever. The mask is taken out of the nest, and the door opens.

To break the bow, use open-end wrenches. Position the keys so that the shackle is between the horns of the keys. The tools will touch each other. Move the opposite ends in different directions and when the keys rest, press down. The bow will break or fly out of its socket. Using the same principle, you can quickly break a padlock using a hammer and a pry bar.

How to deal with complex mechanisms?

As mentioned earlier, opening a padlock can be tricky. It is manufactured in various types, respectively, classified by size, quality, cost and, despite the fact that all these products belong to the type of padlock, they have enormous differences.

For example, a very common type of mechanism is a spring lock. Accordingly, if there is a need to open the room, it is necessary to exert influence on the internal spring. In most cases, a spring lock is used as additional protection or hung on the doors of barns, outbuildings, or used to cover certain luggage.

It is also necessary to influence the spring using special tools. In practice, try to independently select a product that will perfectly fit the size of the lock, and apply it to the spring. Such a product can be either a pin or a nail.

Hacking the cylinder mechanism

The cylinder mechanism has its own characteristics and several methods of hacking. The next method is the most effective and common.

You will need a screwdriver, with which you screw the self-tapping screw directly into the lock cylinder.
The destroyed mechanism is leveled using a nail cutter.

How to pick a lock without leaving it intact?

Opening a padlock without breaking the integrity is a task for an experienced locksmith. There are two methods that can be used for this purpose, but they require skill and patience.

For the first, you will need a strip of aluminum measuring 4x10 cm. The strip is drawn with three parallel lines into 5 parts. The middle line will divide the strip in half. Then the bottom half needs to be divided again into 5 parts with vertical stripes. From the end of the middle vertical strip you need to draw a line to the intersection of the adjacent vertical and horizontal strips. Then mirror this with the second vertical stripe. The result is a triangle. It needs to be cut with scissors. Then fold the remaining strip so that it is comfortable to hold with your fingers. How to do this, everyone decides for themselves.

The flat tip of the triangle is then pressed into the gap between the shackle and the socket where the shackle is inserted to close the lock. With force, the triangle is inserted into this hole, and the bow opens. Now you know how to open a padlock without a key.

You can use a paper clip and a women's bobby pin. The invisible piece needs to be cut into 2 parts with pliers. Then flatten the cut area. The master key is inserted into the lower part of the hole in the lock, then bent. You need to turn the hairpin several times, and then use a straightened paper clip.

The paperclip is inserted all the way into the deep part of the hole. After this, the pin must be loosened from side to side, pressing it to the bottom of the socket. If everything is done according to the instructions, the structure will open and the lock can be removed. This method is used to open a mechanical lock, but it is not always successful the first time.

Tips and tricks

Even if everything is done correctly, the socket will become loose and will not hold the bow tightly. It is better not to use the device after opening, and to use a master key for opening only if you have lost the key.

Important! The opening method depends on the quality of the shackle and the manufacturer. The Chinese mechanism can be knocked down on its own, but with German models you should be delicate.

Metal can be sawed through. It's only a matter of time. Therefore, if none of the methods work, you can cut down the old device with a hacksaw. But if it’s freezing, the device may simply be frozen. In this case, the structure needs to be warmed up and under no circumstances should you try to saw through it - this is not the best remedy in sub-zero weather. It’s easier to disassemble the handle or wait for a thaw, leaving the door closed.

It is not so difficult to pick a lock, but after doing so it often becomes unusable. This should be taken into account before starting the procedure.

Conclusion

This text in no way teaches you to open other people's locks and does not encourage you to commit illegal actions. It is purely for informational purposes, ready to help you in a difficult situation and once again emphasizes that if you care about the safety of your property, then you should not skimp on locks, especially padlocks.

As you know, a stingy person pays twice, and a stupid person pays three times. Therefore, before purchasing a padlock, read the technical data sheet of the product, which confirms that the lock has passed certification tests and its characteristics are not nice words.

Evaluate the weight of the lock, the hardening of the shackle, the security class; if possible, give preference to closed models that hide both the shackle and the eyes in the case. Your peace of mind is in your hands.

This article will not talk about professional methods. All methods are designed for the unfortunate owner who finds himself in front of his own closed door. To open a lock you will need simple tools and items that almost anyone has. You can take them from the garage or ask your neighbors.

How do door opening specialists work?

A specialized company knows how to deal with “rebellious locks” and has the necessary arsenal of tools. Experienced craftsmen can handle any mechanism and help make the lock work.

To open the entrance doors, you will need to confirm your right of access to the house or apartment. This may be a passport stamp with registration at the designated address or a document confirming ownership. The operation can be carried out in the presence of two witnesses and a local police officer.

Breakdown of the button mechanism

There are door designs with a latch button on the inside. When the door slams, the button is pressed and opening the door from the outside becomes impossible. It also happens that the door is locked with the button pressed, and there are no people in the room at that moment.

To solve this problem, lock designs of this type provide a small hole directly under the door handle. Insert an awl or knitting needle into it and press it. This should set the button to open mode and the door will be unlocked.

Types of locks

Before you start opening the lock, you need to understand its mechanism. This will help you understand how the secret works and it will be easier to understand all the steps to unlock it. Overhead and mortise locks are divided into 2 types:

cylindrical;
disk cylindrical;
suvaldnye.

Cylinder locks have small, flat-shaped keys that have grooves, indentations, or recesses on them. When the key is inserted into the lock, its configuration positions the locking pins (the so-called “pins”) in a certain order and the cylindrical part rotates, moving the bolt.

A separate category of cylindrical locks are disk (Finnish) locks, the secret of which consists of a set of disks. Such locks often have a part protruding beyond the door leaf, in which the lock cylinder is located. To open, a semicircular key with recesses is used. When you turn the key, the discs line up in a certain sequence, and the key turns further, opening the lock.

Lever locks have a characteristic wide slot for a key, which has a long shaft with two bits (rarely one). The beads have protrusions and depressions that are designed to displace the levers and move the crossbar.

Classification of locking mechanisms

Cylinder locks can be divided into three security groups:

Low privacy (up to 10,000 combinations);
Average privacy (up to 5,000,000);
Highest secrecy (from 100,000 billion combinations).

The former are characterized by low manufacturing accuracy, lack of protection against master keys, and weak materials. The main representatives of such locks are the “English key”, double-sided “English key” and cross key . An experienced specialist can open such locks in a matter of seconds. The second category is distinguished by more serious claims: average manufacturing accuracy, pin placement is more complex. Protective elements and special durable materials may be present. Locks are represented by such companies as TITAN (Slovenia), SUPERLOCK (GARD) (Israel), MUL-T-LOCK (Israel), CISA (Italy), KALE (Turkey) and so on. Key of the “Punched card” type. The third category, the highest secrecy, has all the protective elements, wear-resistant materials, and a complex arrangement of pins. Very difficult to open. The highest quality locks are represented by KESO (Switzerland), ABLOY (Finland), DOM (Germany), CISA (Italy), KABA (Austria), EVVA (Austria) and other brands. They are opened with high-quality “punched card” keys, as well as “Finnish” keys (ABLOY company). Lever systems are easier to classify, as they are represented by locks with a single-bit key and a butterfly key, the quality of which depends on the price of the product. If there are a sufficient number of levers (more than six), the lock is considered reliable. The “butterfly” key looks better in terms of security, since the two-way system is less susceptible to hacking - the secrecy of the lock is increased without increasing the number of levers. The presence of protection against drilling, a high-precision key and levers, and special teeth on their surface make breaking even more difficult.

How to open a cylinder lock

Insert a pin bent into a plate into the keyhole and turn it in the direction the lock opens. After this, create tension and maintain this tension throughout the entire process. Then quickly move the second pin along the pins, you should hear a series of clicks and the lock will turn.

If you cannot open the lock using pins, then use a screwdriver (drill) and carefully drill out the “secret” (you will need a drill with a diameter of 10 mm). After which you will have access to the rotating mechanism that moves the bolt. Using a flathead screwdriver, you can easily open the lock.

What to do if the key gets stuck

First, you need to treat the mechanism with silicone spray and carefully, slowly, remove the key. If this method does not help, the key must be clamped with pliers and slightly loosened. After this, spray a little water inside again and carefully turn the key again.

Advice:

After spraying the water, you should move the wrench slightly for maximum distribution of the lubricant, wait 20 minutes and only then remove the wrench.

If this is successful, you need to change the cylinder or lock, otherwise the situation may repeat. If there are no problems when the door is open, but when the door is closed the key gets stuck, the door frame needs to be bored. A grinder, drill or ratfil is suitable for this.

The key is broken in the lock

What to do if the key breaks inside the lock:

Try to remove it with pliers if a small piece sticks out.
Use a jigsaw if the key is too far inside. Send the jigsaw blade into the keyhole from below and twist it to engage the key. Try to carefully remove it along with the remains of the key.
When you can’t get the key out, unscrew the lock and pull it out.

How to open a semicircular (Finnish) lock

The secret of this lock consists of a set of disks and a balance rod. The rod rests against the collar and prevents the disks from turning. When you turn the key, the discs line up in the desired position under the balance rod. It fits into the slot and nothing interferes with further rotation of the discs.

To → open the lock (see the link for another article about opening locks), insert a flat-head screwdriver between the bar and the protruding cylinder, then pull the cylinder towards you. As a result, the shank will come out of the groove and through the resulting gap, using a thin screwdriver, it will be possible to turn the crossbar drive.

If you can’t pull back the cylinder, you can simply knock off the protruding part where the plates are located and gain access to the insides of the lock. In this case, it can be opened with a simple screwdriver.

If there is no protruding part, then use a “roll” made of hardened metal. Simply drive it into the hole and turn it using the lever.

Options for opening the lock of interior doors

When an interior door closes, many people immediately think of removing it from its hinges. This option is suitable if you are inside the room, if you have access to the fittings. It is enough to remove the decorative plug installed on the hinges and remove the pin. The canvas is easily removed from the opening.

But what to do if children are locked in the room, and not every girl will solve this problem. In this case, it is important to determine which components were used. The fact is that manufacturers install simple locks on the interior panels, which our recommendations will help you open.

When closing the latch from the inside

Most often, locks on interior doors are equipped with a key on the inside. It often snaps into place due to a strong tug on the handle. If you have such trouble, look at the castle from the outside. It has a small hole at the bottom. You need to insert a thin knitting needle into it all the way and press the handle. This will push the button outwards and open the lock.

How to open the lock mechanism

The situation is more complicated if the interior door has a locking mechanism with a key. It can be opened as follows.

Pull the handle several times. If the mechanism is loose, the bolt will bounce off on its own.
Can be opened with a thin object. It needs to be inserted into the well and, slowly turning, move the pins away.

How to open a lever lock

Leveler systems are a set of plates (levelers), which, using a key, are arranged in a certain order and release the bolt shank post. There is a toothed comb on the shank, on which the key presses, moving the bolt. When you turn the key, the shank is released and the bolt moves one step to the side. Basically, 2 or 4 half turns are needed to fully open or close the lock.

To open the lock you will need 2 master keys:

1 you will move the bolt;
2 is needed to press the levers and release the bolt (shank).

The key has a drive tooth, which moves the bolt; it has a height of about 10 mm. You can make the first master key from improvised means (an electrode or a nail), bending the edge so that it protrudes 10 mm. The second pick is approximately the same size, since the protrusions cannot be larger than the drive tooth.

To open the lock, you need to use 1 master key to first push the bolt, and holding it under load, use the 2nd master key to press each lever until it clicks, thereby releasing the bolt (shank). Modern locks use from 4 to 8 levers.

As a last resort, if the insides of the lock are damaged during burglary, then the only way to open it is to drill out the very shank of the bolt that keeps the bolt from moving. This is not an easy process as you will need a lock template that is positioned along the keyhole and will indicate the exact location of the shank. After this, you can use a master key to move the bolt without any problems. If you were unable to open the lock yourself, contact a specialized company for opening locks, such as → zamok-sos.com.ua.

Types of hinged locking devices and approaches to opening them

Hinged locking devices are heterogeneous in appearance and design. They differ from each other in the shape of the bow, the configuration of the case, the location of the keyhole and much more. Let's look at the main types of padlocks.

Padlock with a “bare” shackle. The classic bare shackle lock has a square body that is supported by a semicircular steel shackle. Its design is familiar to every child. When this locking device is opened, part of the base of the shackle is lifted, exposing its edge. From this edge, the lock is hooked onto the lugs, thus closing the doors or gates.
Padlock "nicknamed the fungus". An unusual-looking padlock, which has a body in the shape of a cylinder or cube. The role of the shackle in such a lock is played by a thick rod made of hardened steel, one end of which is crowned with a thickening washer that looks like a mushroom cap.
Padlock with protected shackle. The body of this padlock is made in the shape of an inverted letter “c”, the edges of which are closed by a short shackle. The body of the locking device is stronger than the shackle and in this design variation of the padlock, serves as additional protection for it.
Padlock with fully protected shackle. The body of this locking device is similar to the lock described above, but its shackle is even more tightly closed by the body. You cannot hang such a lock on ordinary eyes, because the open part of the shackle is very small, so in order to hang a locking device, you need to weld the eyes exactly under it and only then install the lock.

There are quite a few approaches to opening hinged locking devices, but they all boil down to two main directions: brute force breaking and intelligent opening. Brutal burglary involves damage to the locking device, its purpose is to break the lock or door along with it in order to gain access to the room. Intelligent opening involves unlocking the locking device without damage or causing minor damage using special devices.

Important! It is generally accepted that the crude method of breaking into a hinged locking device is faster, but in reality it all depends on the professionalism of the burglar and the secret features of the device.

Rough hacking of a padlocking device

Despite all the tricks of manufacturers aimed at protecting their locking devices, their rude opening is the most beneficial thing for attackers. To open such devices, there are many devices, the purpose of which is purely economic, but cunning attackers have adapted them to break into hinged locking devices.

Nail puller or crowbar. A powerful steel nail puller or crowbar has long been one of the main tools used to commit thefts. The easiest way to use such devices is to open a lock with a bare shackle. To do this, the tip of the crowbar is inserted into the shackle of the hinged device and the lock is broken with a sharp forceful push to the side.
Hydraulic tool for cutting reinforcement. If a padlock can be broken with a crowbar without unnecessary noise, then with a hydraulic tool this can be done almost silently by simply cutting through the shackle. Only a 20 mm thick hardened shackle can withstand such a tool, so when buying a lock, carefully evaluate its real protection.
Hammer and wrench. To open a padlock using these tools you will need to make a little noise. We take a large open-end wrench and insert its working part between the shackle and the body from top to bottom. Then we hit the base of the handle with a heavy hammer so that the key impacts the body of the locking device. One strong blow is often enough to break.
Thick steel cable and truck or SUV hitch. Everything is simple, rough and primitive. We tie the cable on one side to the towbar of the vehicle, and on the other to the shackle or even to the eyes on which the padlock is located. Next, start the engine and press on the gas.

We consider further consideration of crude methods of opening a hinged locking device to be inappropriate, because there are a lot of them and most people are familiar with them in one form or another. In addition to these tools, burglars of all stripes use grinders, drills, gas cutters, and sometimes just sledgehammers. If there is no need to hack secretly, then the list of tools suitable for this will expand significantly.

Important! Even the best lock breaks over time, especially if it is used outdoors. In order for the lock to serve for a long time, it requires care, which means cleaning and lubrication.

How to open a padlock without a key

Today, an old padlock is often found in a garage, pantry, attic or warehouse. The main advantage and reason for the prevalence of a padlock is its low cost, simplicity of design and, at the same time, reliability.

It is simply impossible to open a door with such a lock if the key is lost, because... the lock shackle is made of steel, and garage and warehouse doors are usually metal.

Also often the reason for the inability to open the door is wear and tear of the security mechanism. Over time, due to regular use, its internal secretion may simply wear off. If the lock hangs in the open air, due to the influence of external factors (moisture, frost), the formation of corrosion centers is simply inevitable. In this case, if there is no desire to use an angle grinder and damage the canvas, anyone will think about how to open a padlock.

This is actually a fairly common problem. Many different methods have been accumulated to solve it. Many people resort to a master key made from an aluminum can. You can easily make a shamrock shape using an empty Coca-Cola can. The mechanism itself is broken using the middle tongue.

Opening with a paperclip is the most effective and long-proven method of working with a jammed padlock. The specificity is to get a bent paper clip or wire into a special clamp, which should unclench and release the staple from the base. In some samples, a button is provided instead of a latch; the operating principle is not much different. A wire bent in the shape of an G must be inserted into the hole and slowly and carefully turned.

It is important to remember that during rotation you should pay attention to which direction the mechanism turns easiest.

Next, a second master key of the same type is used and inserted into the upper area of the keyhole in order to find special pins, which, after detection, gradually rise. After all the pins are open, the lower pick is turned again.

In most cases, you can open a padlock yourself using a regular pin, knife, or special master keys, which can be found in craftsmen or locksmiths. You can learn more about how to open a semicircular padlock without a key in the corresponding video. Often, with the help of o, it is important to assemble the required lock combination, which is presented in the form of a set of ordinary horizontal plates.

It should be noted that some models of padlocks with a semicircular key are quite resistant to burglary, so their owners often turn to specialized services.

Determining the cause of the malfunction

The first thing to do is to establish the reason why the lock is jammed. This can be problematic right away, because the lock is embedded in a metal or wooden door, and even if it is overhead, it is unlikely that you can directly open its body.

Based on the information received, the method by which the autopsy will be performed is selected.

A key jammed in the lock implies 2 types of breakdowns: the key has a certain degree of freedom (limited movement) or does not turn and is not pulled out at all.

Partial movement indicates that the lock secret has broken, or some kind of blocking, foreign object has gotten into the keyhole.

If there is no movement, then the secret itself is jammed. Also, the reason may be that a key that is suitable in configuration, but not the “original” one, or original, but has significant damage, is inserted into the lock. This applies to both regular and round keys.

If the door lock does not open, but the key is easily inserted and removed, this indicates a broken secret, or perhaps, as in the first case, a foreign object has gotten into it. It can also be assumed that the movement is hampered by a jammed shank of the bolt or crossbars, which happens, most often, when installed incorrectly, when the fastening, fixing and adjusting screws are overtightened, resulting in distortions and disruption of technological clearances.
The lock does not open, but turns one turn. Here you should inspect the key to identify significant damage that cannot be corrected and that does not allow the lock to recognize the original key.
A separate category is the magnetic lock. What to do and how to open it depends on the type of locking mechanism - it can be a regular bolt or an electromagnet. In the first case, a power outage deactivates the magnetic lock in the closed position, and in the second, in the open position.

There is not much difference between how to open a padlock and a regular one - in general terms, their mechanisms are the same. Only the most common, most common causes of lock malfunction are described here, which are given to understand the algorithm for opening them.

How to open a combination padlock

In this case, there are several ways. The first and most common requires the selection of a combination. First, you need to pull the locking shackle until it begins to put pressure on the wheels. After this, you should make rotational movements until a click occurs and the lock opens.

The second method is more complicated. To open it, you will need an aluminum plate, which can be cut from a tin can. This semblance of a key is rounded to a diameter corresponding to the width of the arch. The plate is inserted into the hole located between the body and the bow. At the very end, after the procedures have been completed, it is necessary to apply some force for final unlocking.

How to open a disc padlock

A characteristic feature of this mechanism is the presence not of pins, as in other models, but of several disks with specific holes, which significantly complicate entry into the room. To ensure that the discs are placed in the correct position, it is important to select a wrench with suitable grooves.

Padlock disc

Considering the specificity of the design, with minimal loss of time, you can open a disc padlock without a key only with a correctly selected master key or a bent flat-head screwdriver, which must be driven into the lock and turned with force.

How to open a barn lock without a key

It is important to remember that barn locks are those samples that have a standard round shackle. Therefore, old-style garage locks often fall into this category.

A medium-sized and small-sized lock installed on a wooden door can also be opened by force. A regular crowbar is suitable for this purpose. It is necessary to insert the tool through the bow and, using the lever method, tear it off.

It will be more difficult to open the rack lock using the method described above, so here it is worth using fishing line or a string from a guitar. First, you need to press the door with a crowbar, then a loop is made from a string, which must be inserted into the hole, circled around the pins and pulled towards you. For clarity, below is a video.

How to open an Apecs lock without a key

For those who have wondered how to open a padlock from such a manufacturer, any specialist will answer that the methods are practically no different from those given above.

It should also be noted that Apex's products are designed for mass use and their price does not exceed the average. Therefore, hacking this mechanism will not take much time and effort.

How to open a Chinese padlock without a key

Samples made of Chinese steel are, as a rule, unstable to force. The steel of overhead locks is quite soft, so if you have an angle grinder, the opening process will not take much effort and time.

When using a crowbar, you will need to apply force, but it is still important to choose the right angle.

Lockpicks

Online stores sell master keys for such locks. With a little effort, you can make them yourself.

You can open a disc lock using the following scheme: create pressure on the rotating part of the cylinder, then use a master key to select the correct position of each closing element until the slots completely coincide with the rod.

Opening a lock with a master key

With the help of a professional tool, the mechanism opens in this way: at the same time pressure is created and the discs are rotated one by one. For this, there is a special graduation of rotation, depth and angle, which conveniently rotate the disks, moving them from one element to another. For master keys that are made independently, it is better to use knitting needles or thin tubes. To open a lock with such devices, you will have to devote more time and effort to do the job accurately.

Lock opening algorithm:

Turn all parts of the system in one direction until the very end, as soon as it gives in (forward):
Press the lever in the direction where the lock opens until it stops;
Use a master key to get to the far border (away from you), then turn it to the side and forward again;
Perform these actions until you find a moment and feel resistance;
This moment indicates that the groove is opposite the rod;
Perform such actions with all disks one by one;
At one point you should hear a click, this means that the lock has given way and opened.
Once all the slots are in the correct position, press the lever and open the lock.

Opening without a key

Before opening the lock, it is worth determining its type. automatic, then the door can slam itself, if semi-automatic, you should press a special button. If a disc mechanism malfunctions, regardless of whether it is surface-mounted or mortise-mounted, it should be replaced and the automatic closing function removed.

Lock with semicircular key

If you need to open a lock without a key, there is a simple method that does not require much skill - knock out or simply break the cylinder with a code plate - it looks beyond the boundaries of the canvas. There is also a simple way to open a garage padlock. It consists of removing the pressed ring that holds the larva. Then pour out the secret plates and use a screwdriver to turn the auxiliary mechanism.

Prevention of breakdowns

Perform periodic preventative lubrication on your padlocks. Mechanisms must be lubricated exclusively with special household oil. Such prevention will be relevant not only for padded locks, but also for absolutely any other locks - except electronic ones, of course.

Lubricating the lock will significantly extend its service life and will also help withstand the negative effects of various atmospheric factors. Including moisture and low temperature.

Types of locks

When ordering a door, the consumer, in addition to the design itself, selects additional fittings. Mortise cylinder and lever mechanisms are usually used. Products with several security mechanisms, which are placed in one housing, are also installed.

Cylinder mechanism

A disc lock is a type of cylinder lock. It is opened with a semicircular key, which passes through the hole in the frame, which has a spring on the side. Frames connect the cylinder mechanism to the body. Using this key, rotate the disks to open them.

Disk device

The secrecy of the design is determined by the number of possible combinations. 10-5000 possible combinations in the absence of a protective element are considered low.

Bumping is one of the methods by which pin cylinder devices are opened. This method is based on the use of a special tool that pulls the core out of the body. To do this, a channel is drilled at the boundary of the cylinder device body, through which the remains of the retainer and springs are removed.

Opening with bumping

Imported disk mechanisms become unusable due to constant friction between the key and the working part.

A disc lock is a type of cylinder lock; their difference lies in the secrecy of the device. In this product, instead of a pin, a whole set of round disks with recesses and special holes is used.

The main problems of disc locks

Most often, situations in which the lock cannot be opened in the usual way are associated with the following circumstances:

Lost or broken key. Keys for disc locks have a fairly robust design due to their crescent-shaped cross-section. Therefore, it is very difficult to break them - this requires a lot of effort;
Natural wear and tear of the mechanism. It usually appears either after prolonged use or as a result of using the locking device in difficult conditions - for example, in damp or dusty rooms, outdoors, etc.;
Actions of attackers. Very often, trying to break into the front door, burglars break the lock and, unable to open it, leave;
Mechanism clogged. It can occur both for natural reasons and as a result of the actions of vandals.

Opening methods

Here are the available options for opening such a device without special tools.

Knock out the protruding part of the lock using improvised means. After this, the mechanism will open with a flat-head screwdriver, but then the lock will have to be repaired - the cylinder must be replaced.
Open with a roll. To do this, place a roll in the hole where the key is inserted and use a wrench to turn it in the mechanism. After this, repairs will also be required, but the door will be able to be opened.
To unlock the lock without damaging it, you will need to prepare a slotted screwdriver and insert it between the cylinder and the handle adjustment. Then pull the cylinder towards you. After this, a small hole will appear. Take a flat-head screwdriver and turn in the desired direction. This method is not suitable for all models.
There is also a method that requires a hammer and a wide screwdriver. They knock down the fixing screw. After opening the door, the mechanism is disassembled and a new screw is installed.
A radical way to lock a padlock is to use an electric grinder. But it is not always possible to connect the instrument to the network. In this case, you can use a crowbar, apply a little force, and the lock will open.
Considering that the larva is held in place by a special ring, you can try to remove it. After this, remove the secret plates and try to open the mechanism using a flat-head screwdriver.

Tensioner

Now you need to make a tensioner, the task of which is to turn the lock. With its help you will press on the cylinder, and with another paperclip you will simultaneously put the pins in place. There are two ways to make a tensioner from a paper clip.

The first, simpler one: bend the long end of the paper clip at a right angle. This way you will have the basis for a working tensioner, but not a very good pick.

The second, a little more difficult: completely straighten the ends of the paper clip so that the wire bends in the middle and the ends meet. In this case, one of them should be slightly shorter than the other. Then the longer part must be bent again at a right angle, about a centimeter from the tip.
