ABSTRACT:
In an electronic digital safe lock including a slide plate pivotally connected by an articulated linkage to a bolt operating lever for retracting safe door locking bolts after digital input of the electronic lock combination, a lock override is provided which includes a dial operated mechanical combination lock having a linkage pivotally interconnecting the manual combination lock bolt with the electronic lock articulated linkage of the slide plate and bolt operating lever. When the electronic lock is locked, i.e., the slide plate is immovable, the manual combination lock can be manipulated to operate the aritculated linkage to operate the bolt operating lever independent of movement of the slide plate.
