Melt with a gas burner
Locks are often made from silumin, an alloy of aluminum and silicon.
The lock is heated with a gas burner.
Silumin melts when heated to 480 - 670 degrees Celsius. A minute of heating - the case will melt and the lock will fall.
Security measures. Clear the work area of flammable materials, cover it with sand, and cover it with a sheet of metal.
We use a lever made of two wrenches
Breaking the lock body or shackle. Use two large wrenches as levers. They are inserted into the space of the shackle near the lock body and the free ends are moved together.
The longer the keys, the less effort. Large keys can be inserted between the body and the top of the lock shackle.
If you have access to liquid nitrogen
It is known that metals become brittle when overcooled. The lock body is made of non-frost-resistant materials. If the lock is cooled to the brittle temperature of the metal, it can easily be broken with a hammer.The metal is cooled with liquefied nitrogen or oxygen.
Pour liquefied gas into a glass glass and hold the lock in it.
Attention. It is dangerous to take a glass with bare hands - you can get frostbite on your hands.
A couple of minutes of cooling and the lock is broken with a hammer blow or with mitten hands.
Destruction by “burning” using a thermite mixture
They set it on fire with a special ignition strip. When burning, it gives a temperature of 800 - 850 degrees Celsius and heats the mixture until it ignites. When the powder burns, its temperature increases to 2000 - 3500 degrees Celsius.
To use this method of destroying a padlock, you need to lower it into some container, for example, made of magnesite, pour thermite powder into it and insert the ignition strip.
Place a sheet of asbestos on the bottom, but not metal. Drops of burning thermite can burn right through it.
Attention. It is better not to approach it until the mixture finishes burning.
Use master keys
Next method. Manipulative opening, that is, they open with master keys of different shapes. Used for the so-called. "English castle" This lock has a cylinder mechanism based on a set of pins. The pins are cut into two, usually unequal parts, and are spring-loaded.
A flat key with a shaped cross-section, having teeth on one side, is inserted into a shaped slot in the cylinder. The spring-loaded pins, with the teeth of the key, each rise to a strictly defined height. The cut locations of all pins form a line coinciding with the outer surface of the cylinder. After this, the cylinder is turned with a key and the lock opens.
An aluminum can will help us
A T-shaped figure is cut out of thin elastic aluminum, for example, from a Pepsi-Cola can.
The “leg” of this “letter” is placed in the gap between the lock shackle and the body.The upper part is wrapped around the shackle and, like a handle, the aluminum figure is turned around the lock shackle.
She pushes back the latch that holds the shackle in the case. The lock opens.
There are other simple ways to “deal” with a closed lock without a key: cut the shackle with a cutting torch using gas or electric welding, cut the shackle with hand wire cutters, cut it with the cutting disc of an angle grinder.
