An inductively coupled electronic lock system wherein a key unit receives binary multiple bit data and generates a binary frequency modulated carrier which is input to a transmitter inductor. A lock unit of the system has an inductive pick-up which compares the received sequence of binary signals with a predetermined sequence of binary signals so that upon a proper correspondence a motor opens the lock.

An electronic lock system comprising, in combination: key means including generating means for generating a plurality of binary frequency modulated carrier waves, first inductor means electrically connected to said generating means; lock means including lock inductor means positioned to inductively couple with said key inductor means when said key means is in predetermined spatial relation to said lock means, signal distinguishing means electrically connected in circuit of said lock means and disposed to receive signals from said generating means whereby a predetermined sequence of binary signals is compared with the sequence of binary signals contained within the carrier from said generating means, motor means electrically connected in driven relation to said signal distinguishing means so that upon a corresponding comparison of said signal distinguishing means said motor means is activated, lock lug means connected in movable, driven relation to said motor means, whereby activation of said motor means causes movement of said lock lug means between a locked and unlocked position.
