ABSTRACT:
An electronic safe has a secure housing including a lockable door thereto, a programmable control unit within said housing, a keyboard mounted on an external side of the housing and connected to the control unit, whereby a user can program a selected combination code into the control unit through the keyboard, a motor driven lock bolt for locking the door to the housing upon the programming of a combination code by a user and closing of the door, and a program control for recognizing entry of the selected combination code to open the lock bolt to permit access into the safe. The electronic safe further has a display for displaying the codes entered by the user, and an override device for randomly generating an alternate code and permitting access into the safe upon entry by the user of an override code corresponding to the alternate code. A pull-out component is also provided for altering the alternate code generating program in the event the security of the override code list has been breached.
