ABSTRACT:
A keysafe has tumblers which are set by a key-like programmer and has combination wheels which, when correctly set, have slots which receive the set tumblers. Thus, there is a unique combination for each programmer. In order to reset the combination wheels to their beginning, reference position, a slot is provided in each combination wheel, together with a lock bar which can enter the slot when the combination wheels are in the reference position. This lock bar is actuated to permit the programmer to be withdrawn.
