摘要: A locking device for utility locks having a lock bolt, wherein key signal transmitter is disposed in portable housing and stationary receiver the vicinity of bolt controls operation bolt. The has coder generating predetermined code specific to device, decoder decoding generated by coder. employs coding format which sequence at least three pulses, characterized different pulse widths transmitted decoded thereat unlock upon sequence.
