ABSTRACT:
An electromechanical key safe includes a housing with a region defined therein. The region can be closed by means of a pivoted door attached to the housing. The door carries an electronic control system as well as a manually operable keypad. In response to entry of a sequence of characters through the keypad, the control system compares the entered sequence to a predetermined sequence of valid combinations. If a match is detected, the matched combination is checked to determine whether or not it is enabled. In the event that a matched combination is enabled, the lock system can be unlocked or actuated. In the event that a predetermined and matched combination is not enabled, the lock system cannot be unlocked.
