Abstract (en)
Key-operated locking device e.g. for electrically actuated vehicle door locks in which only the correctly cut key (21) will displace a row of tumblers or wards (22) to bring apertures (26) therein into alignment. A light emitter (16) emits a light beam through the apertures as the key is inserted and if alignment is correct the beam is sensed by light responsive sensor (17) to generate a signal applied in a control circuit to release the door lock and/or operate other equipment.
