Claim:
1. A self-powered lock system for a movable member, the system comprising: an energy storage device having an electrical charge stored therein; a generator coupled to the storage device and operatively connected to a lever of the movable member, displacement of the lever driving the generator to generate electrical energy and store the generated electrical energy in the storage device; a lock mechanism having a first state in which the movable member is locked and a second state in which the movable member is unlocked; a control unit coupled to the lock mechanism and adapted to place the lock mechanism in one of the first state and the second state; a trigger unit adapted to be activated with the lock mechanism in the first state, the trigger unit comprising a keypad having a plurality of keys; and a passive detection unit coupled to the trigger unit and to the control unit, the detection unit detecting activation of any one of the plurality of keys while consuming substantially no electrical energy and, upon detection of the activation, providing a conductive path between the control unit and the storage device, thereby powering the control unit with the stored electrical charge, the control unit, upon being powered, placing the lock mechanism in the second state.
