A safe locking system that provides a means to operate one of two (or more) safe locks of any type to facilitate safe opening of a door. The safe door can be opened by operating either of two locks, regardless of the type or style; e.g., e-locks and mechanical locks. A sliding bar assembly is mounted to the rear face of the safe door for displacing the boltwork into and out of the door frame. Extension of the lock bolts of both locks prevents movement of a main locking bar and attached boltwork, which prevents a user from opening the door. Retraction of either of the lock bolts permits sliding movement of the main locking bar, such that a user can unlock the door from the frame.
