Guide MIT on the opening of locks picklock

This chapter contains a series of exercises that will help you develop the basic skills of opening locks with a master key. Some exercises develop only one skill, some are dedicated to developing the coordination of different skills.

During the exercise, concentrate on the process, not on the outcome. If you focus on the result, nothing good will come of it and the learning process will be lost. The goal of each exercise is to learn something about the castle that you hold in your hand, and something about yourself. When the lock opens, remember what you did and what you felt immediately before the lock was opened.

Exercise should be given short intervals. If you perform them for more than half an hour, your fingers will become achy and you will lose the ability to reach the required degree of concentration.

Chapter 8.1 Exercise 1: Motion of the Picklock

This exercise helps to master the skill of applying a fixed pressure picklock, regardless of how the master key moves in the lock. Basically, you need to learn what you need to do, so that the master key "jumps" up and down in accordance with the resistance provided by each pin.

Very important in applying a fixed pressure is how you hold the master key. It needs to be held so that the pressure turns out to be fingers or a wrist. Elbow and shoulder do not have the agility that is necessary for opening locks. When you "comb" the lock, notice which of your joints are immovable, and which have the ability to move. Pressure is moving joints.

The master key can be held by two fingers, which form the fulcrum, and the third finger acts as a lever for applying pressure. What kind of fingers to use for this is the matter of choice. Another way is to keep the master key as if you are holding a pencil. In this case, the pressure exerts a wrist. When pressure exerts a wrist, the shoulder and elbow must provide the force required to enter the lockpin into and out of the lock. Do not use your wrist in order to simultaneously move the master key and apply pressure.

In order to "feel", like a skeleton jumping in the keyway, it's good to try combing the pins of the open lock. The pins are fixed at the top, and it is necessary to adapt the master key to the heights of the pins. Try to feel how the pins "ruffle" when the master key moves over them. If you quickly spend a master key on the pins, you will hear this rutting. This same feeling of hummocking will help you to point out that the pin has pushed right. If it seems that the pin is pushed, but it does not roll, then it will be pushed incorrectly. Incorrectly pushed pins can either be pulled down, or weaken the moment of rotation provided on the cylinder; In this case they will return to their original position.

And the last tip. Concentrate on the tip of the master key. Think not about how that part of the master key moves in your hands, but how the tip moves.

Chapter 8.2 Exercise 2: The Pressure of the Lock Pig on the Pins

This exercise will teach you in what range you need to apply pressure picklock. First, apply the pressure picklock to the pins when you pull it out of the lock. Once you have learned this, try to apply pressure to the pins while inserting the master key into the lock.

Use the flat side of the master key to press the first lock pin. Do not give the cylinder a torque. The amount of pressure exerted by you should be sufficient only to overcome the resistance of the spring. This resistance gives you an idea of ​​the minimum pressure that you have to provide with a master key.

As the pressure on the pin is applied, the spring resistance increases. You must feel this resistance.

Now you need to feel how you push on the other pins as you take out the lock pick from the lock. Begin the procedure by inserting the picklock with the lever into the lock, but do not give the cylinder a torque. While removing the lock picks from the lock, apply sufficient pressure to move up all the pins.

The pins must jump back into their original position after the pick passes over them. Pay attention to the sound produced by the pins. Also pay attention to the sensation of "cotton" when the pick passes along the pin. Also pay attention to the feeling of elasticity, when the master key presses on each new pin.

So that you can better concentrate on these sensations, try to count the number of pins in the lock.

To get an idea of ​​the maximum pressure, the flat side of the master key, push all the pins in the lock. Sometimes you will have to apply the same pressure to one pin. If you meet a new kind of lock, do this exercise to determine the elasticity of its springs.

Chapter 8.3 Exercise 3: Making the Cylinder Torque

This exercise will teach you in what range you need to give the cylinder a rotational moment. It demonstrates the interdependence of the rotational moment and pressure, which was described in Ch. 5 .

The minimum torque that you will use is sufficient only to overcome the frictional force of the cylinder rotation in the body. Using the lever, turn the cylinder until it stops. Note the torque required to rotate the cylinder until the pins come into contact with the walls of the pin holes. This force can be much greater in relation to locks exposed to rain. The minimum torque for padlocks must overcome the resistance of the spring, which is fixed between its rotating part and the bow.

To feel the maximum torque, press the flat side of the master key on all the pins and try to give the cylinder a torque sufficient to keep the pins in the up position after removing the lock from the lock. If your lever is uneven, then you will be able to hold, in all probability, only a few pins.

If you give the cylinder too much torque and push it too hard, the following situation will occur: the key pins are moved too far into the casing, and the torque is large enough to hold them there.

The range of the values ​​of the torque can be found by gradually increasing the torque during the combing of the pins with a pick. It will be more difficult to press some pins. Gradually increase the rotational moment until some pins are pushed. These pins will cease to be elastic. While holding a constant torque, comb the pins with a picklock several times; Maybe, it will be possible to push some more pins.

The most common mistake for beginners is giving the cylinder too much torque. With this exercise, you will learn to find the minimum torque required to open the lock.

Chapter 8.4 Exercise 4: How to make sure that the pins are pushed

When you open the lock, try to determine which pins are pushed. The protruded pin can be pushed slightly further, using a small pressure, but it will be hard to push it even further (for an explanation see Chapter 6 ). When you stop affecting the pin with small pressure, the pin will bounce back slightly under the influence of the spring. Pulled pins are also pounded, if they are slightly poked with a picklock. Try to hear this sound.

Swipe all the pins and try to determine if the pushed pins are in the front or back of the lock (or both). Try to determine which pins are pushed. Remember that the pin number 1 is the pin nearest you to all the others (ie the pin that the key touches first). The most important skill in opening locks is the ability to identify properly pushed pins. This exercise will teach you this skill.

Try to repeat this exercise by turning the cylinder the other way. If the front pins are pushed in one direction when the cylinder is rotated, the rear pins will be pushed when the cylinder is turned to the other side. For an explanation, see Fig. 6.2 .

To determine the number of pins pushed, it is necessary to loosen the torque and count the clicks that the pins are returning to their original position. Try to do this procedure. Try to notice the difference between the sound of one returning to the starting position of the pin and the sound of the two pins returning at the same time. The pin, which is incorrectly pushed, also produces a sound that looks like a click.

Try to do this exercise, applying different values ​​of the torque and pressure. You should note that the more torque you apply, the greater the pressure you must have with the pickpick to properly push the pins. At excessive pressure, the key pins are stuck and remain in the casing.

Chapter 8.5 Exercise 5: Exercise Training

During the exercise, try to present a picture of what is happening. The picture does not need to be visual, you just need to present in general terms which pins are pushed and what resistance each pin has. To train this ability, you should try not to forget your feelings and assumptions about the castle, which you had while working with him. When the lock opens, do not forget about it immediately, keep in mind all that has happened.

For this exercise, you need a lock that can be easily opened with a master key. It will help you improve the visual skills that you need to master the craft of opening the locks. Open the lock. And try to remember what you felt at the time when you opened it. Mentally repeat all actions and all the sensations experienced by you when the lock is opened correctly. In a word, you should mentally review the "film" on which the process of opening the castle was recorded. Imagine the movement of your muscles, when they exert the right pressure and torque, once again feel the resistance of the lock. Now open the lock again and try to make all your movements coincide with the movements on the "film".

Repeating this exercise, you learn to develop detailed commands for your muscles and interpret the data coming from your senses. Mental repetition teaches you to understand the castle at a visual level and to recognize the basic steps of its opening.
