Gear lock with "trap"

All Dierre cylinder locks with geared system are provided with a security system (trap) that blocks the carriage and holds the lock’s latches in a locked position in case the defender that protects the cylinder is attacked.

In the case in which the defender is extracted and the cylinder is broken, the system trips in an irreversible manner by locking the latches in security mode and preventing delinquents from opening the lock.
