The full name of the security door is "security door". It combines anti-theft and security performance. According to the provisions of the "General Technical Conditions for Anti-theft Security Doors", qualified anti-theft doors cannot be pried open within 15 minutes by using ordinary hand tools such as chisels, screwdrivers, crowbars and portable power tools such as hand drills, or open an opening of 615 square millimeters on the door leaf, or open an opening of 38 square millimeters in a semicircle of 150 square millimeters of locking points.

It is best to indicate what brand of anti-theft door, depending on the level of the lock and the structure of the lock body.

Generally, there are several possibilities that the lock company can't open: 1. The lock body is broken and the outside can't be opened. This is good to find someone who can repair the security door.

Sometimes, the shot is made against the lock position, and sometimes it can be opened. 2. The inside is locked. It is the latch inside that is given.

This one is manual and sometimes pops up on its own. This one is best to go in through a window and open the door from the inside. 3. Super B-level lock cylinder, generally the lock-picking company can't open it.

This one can only hit the keyhole with a percussion drill, and the lock cylinder is broken. And the door opened.

This method was first discovered and used. Filling the keywell first requires a complete set of lockpicking tools, as well as multiple foil boxes. Then take out the general lock and special tools, and then prevent the tin foil from entering the special tools, and then with the assistance of another tool, insert the B-class lock cylinder, fix it on a small vice, so as to simulate the unlocking process, and finally only need to shake for about a minute to be able to open.

Insert a key into the B-grade cylinder and then use a hammer to tap the key on the other end, as hard as you can. Just twist the key while tapping, and the cylinder will be opened in no time.
