I bring to your attention a few examples of the criminal 'picking' of locks. One of the simplest methods is to drill out the cylinder pins or bolt shank posts in the lever locks. The factories that make the locks take measures against this, such as: Cylinder covers made of heat-strengthened metal (for example, 'ABLOY' locks). The stem of the deadbolt shank is made of heat-strengthened metal. A steel ball is inserted into the end of the bolt shank post in order to move the drill to the side. Mounting plates of locks are made of heat-strengthened metal. However, there …

Now I will tell you about the methods of unlocking lever locks with the help of a 'roll-up'. Convolution (thieves' slang) - a special device for breaking the locking device of the lock in order to move the crossbars to the unlocked position. I already wrote about the rolls for breaking the cylinder mechanism of the lock, and now it's the turn of the lever locks. A huge number of lever locks, both domestic and imported, have appeared on the market. It is very difficult to independently figure out which of the locks is better if you are not an …

For the purpose of a more detailed explanation of this thieves' method, I decided to make illustrations with descriptions. The essence of the method is as follows. If you leave the key in the lever lock from the inside of the door (and as practice shows, most do), then you can easily take an impression from the key left in the lock using plasticine or …

Within the framework of this article, I would like to conduct a comparative test of two overhead locks with a cylinder locking mechanism. These are the Barrier-2 and Barrier-2M locks, manufactured by OOO Polivektor, St. Petersburg. Castle Barrier-2 Photo 1. View of the castle Barrier-2. Red arrows with numbers: 1 - a metal plate is marked, which serves as a protection for the cylinder mechanism and is an element for fastening the lock; 2 - the handle is marked, with the help of which the crossbar is moved. Lock Barrier-2M Photo 2. View of the castle Barrier-2M. Red arrows with …

Photo 8. View of the cylinder mechanism of the Barrier locks. The red arrow indicates the guide post inside the cylinder. The stand is protected from drilling with a steel ball. The stand is not only a guide for the prickly, but also prevents the pins from falling out of the cylinder. To drill the rack, a guide tube with an outer diameter of 8 mm and an inner diameter of 5 mm was used. The stand was 'damp', so a conventional drill R6M5 with a diameter of 5 mm was used (photo 9). Device for criminal unlocking Photo 9. …

Photo 20. Complete lock. We will drill at an angle, incl. The protective plate is not a hindrance to us again. Photo 21. All metal of the lock is 'raw', drilled just fine. The red arrow indicates the hole in the projection of the rotary knob. Photo 22. The red arrow indicates a hole drilled with a simple drill with a diameter of 11 mm. Photo 23. The red arrow shows the deadbolt locking mechanism, or rather what remains of it after drilling. Photo 24. After drilling the deadbolt locking mechanism, the deadbolt moves through the same hole and into …
