Problems solved by technology

The existing anti-theft locks have a wide variety of anti-theft mechanisms, and the appearance and structure are also very different. The internal structure of the lock cylinder is becoming more and more complicated. There is no essential difference in the technical principles of most anti-theft mechanical locks. Low mutual restraint ability, it is easy for thieves to take advantage of loopholes. At present, some lock-unlocking companies that have been registered in the public security and industrial and commercial registrations are to seize the defects of the existing anti-theft locks and provide unlocking services for users.

In order to overcome the defects existing in the existing anti-theft locks, a kind of anti-theft lock is researched when the user loses the key or locks the key in the room. Highly anti-theft lock with spare key
