Abstract
A permutation lock, particularly for storage compartments, has a variable combination such that an opening combination corresponds to a combination to which the lock was set by advancement of the bolt into the locked position. The lock has an emergency opening mechanism which can be activated and deactivated by key actuation. To increase the security value with simple actuation of the permutation lock, the emergency opening mechanism can be deactivated only by means of a reactivation key which can be inserted into a lock cylinder.
