A safe-deposit box uses a lock including a tongue, a first mechanical device, a second mechanical device, a solenoid, a control unit and a keypad. A renter's key drives the first mechanical device from a first position to a second position to actuate the control unit. The solenoid is in a first position to retain the first mechanical device in the second position. A code is input through the keypad to the control unit to drive the solenoid from the first position to a second position to allow movement of the mechanical device from the second position to a third position to retract the tongue. A clerk's key can drive the second mechanical device from a first position to a second position to drive the solenoid from the first position to the second position and turn off the control unit. If the code is forgotten, the second mechanical device is driven from the second position back to the first position to retain the solenoid in the second position to allow movement of the first mechanical device from the first position to the third position. If the renter fails to pay rent for the safe, the second mechanical device is driven from the second position through the first position to a third position to drive the solenoid back to the first position to prevent movement of the first mechanical device from the first position to the third position.
