A disc locking device with a semicircular key, which is also called a Finnish lock, is quite popular in Russia. It is simple and has fairly good burglary resistance. Also, the advantages of such designs include high reliability and long service life. But even such practically problem-free mechanisms can break down at the most inopportune moment and present their owners with very unpleasant surprises.

Types of hinged locking devices and approaches to opening them
- Opening with a pin. An ordinary hairpin can turn into a master key in skillful hands. Experts push the pin through the keyhole, locate and displace the inner latch, and the lock opens.
- A padlock without a master key can be opened using a bent wire. The principle of its operation is similar to the principle of using a hairpin. The end of the wire should fit freely into the keyhole so that the internal latch can be moved.
- Opening with a master key. A master key is the main tool that helps to intelligently open most locking devices, including hinged ones. The cylinder cylinder of the hinged locking device is opened with a hook-shaped master key and a roll. The hook-shaped pick lifts the pins, and the roller unlocks the shackle.
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.
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.

Now the side petals need to be wrapped as tightly as possible around the bow. The tin from which the battery shell is made is not too hard, so it will not be difficult to perform such a manipulation.
Everyone knows that some locks do not require a key to close them. It is enough to thread the bracket through the hinges and snap it into place, pressing the shackle into the lock itself. If such a lock is struck sharply with a hammer from the side, on the side where the latch tab is located, it will open. In this case, the mechanism will remain undamaged.
Drilling out the housing
In this method, a channel is drilled in the end part of the cylinder mechanism housing, through which the remains of the pins and return springs are then removed. Next, the mechanism cylinder is simply rotated with a screwdriver or any wrench with the appropriate cross-section profile.
To complicate the use of this method:
- protective linings are used (armored lining, magnetic and coded linings)
- the use of protective inserts made of heat-resistant metal in the design of the mechanism, making it difficult to drill out the functional elements of the mechanism
What shape should the record have?
As a result of such actions, within a minute the lock will be opened without damaging the locking mechanism.
First you need to disassemble the AA battery. All you need from it is a tin shell, from which the plate will be cut. Many people say that you can use an aluminum can for similar purposes, but its material is softer. This means that larger locks with a similar mechanism, whose springs are stiffer, will not be able to be opened.
As for the simplest locks, there are usually no problems with them. For example, some of them can be opened with a hammer without damaging the locking mechanism. After such an opening, you can close the lock back and continue to use it as before.

Break or open
With the help of master keys, you can unlock even the most reliable hinged devices, no matter what kind of lock is on your door. But this kind of thing requires a lot of experience. The unlocking principle is as follows. Two devices are made from two paper clips or steel wire. The ends are bent to obtain an L-shape.
The video shows the most popular methods of opening locks.
Existing types of padlocks
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.
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.
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.
Opening without a key
Before opening the locking device, it is worth determining its type. If it is automatic, then the door can slam itself; if it is semi-automatic, you should press a special button. If a disc mechanism malfunctions, regardless of whether it is a surface lock or a mortise lock, 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. For garage mounted type there is also a simple way to open it. 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.
How to pick a lock without leaving it intact?
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.
There are several methods, for the implementation of which you will need a hammer, two open-end wrenches, a screwdriver, a self-tapping screw, a crowbar with a semicircular end, and a metal blade. But there are ways to open it using the most common household items or a pry bar.
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.
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.
The disc lock device operates by determining the balance. If you insert another key, the discs are stationary, and the balance plate blocks the cylinder and the bolt remains in the closed position.
Domestic push-button locks with a semicircular disk design have serious disadvantages:
What are disc locking devices?
Disk devices are a type of cylinder lock, the security mechanism of which consists of a set of disks. Each plate has a recess that allows you to insert a semicircular key. To set the disks in motion and arrange them in the order required to unlock the lock, the geometry of each plate must completely match the key. Despite the comparative simplicity of the design, the disc lock has good resistance to opening by picking. The number of secret combinations can exceed 2 billion, which seriously complicates the hacker's work.
At the same time, this lock is devoid of elements traditional for cylinder locks - pins and springs. This increases their resistance to temperature changes, accumulation of dirt and moisture. Therefore, they are often used to lock street gates, garage doors, doors in warehouses or utility rooms.

To avoid purchasing a new lock after opening the room, you can try one proven method that will keep it intact. To do this, you will need an ordinary tin can: the lid and bottom are cut off, and the cylindrical part itself is cut in half.
Often in a TV series or film you can see how professionals pick locks using the simplest means at hand, for example, bobby pins, paper clips or wire. In fact, this is true - a paperclip is a very effective tool for opening a padlock.
Of course, there are other hacking methods, they do not require painstaking work. For example, you can open a lock with a grinder. It is especially effective on Chinese locks, since their steel is usually less durable. It doesn’t take much time to cut the lock shackle; you just need to apply some effort, and sometimes you can even cut off the shackle with a hacksaw.
Hacking the cylinder mechanism
From one such half you need to cut out a shape like the letter T. Please note that the leg of the letter should be long enough so that it can easily go around the bow of the lock itself. Next, you need to roll the cut out figure into a semicircle and insert its end between the lock body and its shackle. The entire structure rotates in a circle, making a full revolution. Now the lock can be picked, just pull the handle and it will open.
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.
If you need to pick a lock, you will need two paper clips. They are bent in the shape of an L, and one of them is inserted into the lock. You must try to set the mechanism in motion by rotating the paperclip. Make all movements slowly, it is important to feel the mechanism itself in order to open it easier and faster.
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.
Trace method
The key blank is rotated all the way, adjustments are made according to the marks on it, and so on until the key fits.
To complicate the use of this method:
- protective pads are used that block access to the end part of the mechanism (magnetic and code pads)
- mechanisms with a perforated key are used
- mechanisms are used with a combination of different types of mechanism security elements (frames and pins)
- mechanisms with “telescopic” pins are used
