Abstract
The present invention relates generally to security systems, and more particularly, to low cost, highly reliable mechanical-electronic locking units. The electronic security devices of the invention physically include a key assembly, a receptacle for the key in a door or other secured device, a receiver for decoding the signal sent from the key, and a novel electromechanical locking-and-unlocking component which is actuated electrically in response to an appropriate signal from the receiver.
