Abstract
A security system requires the bringing together, at the locking mechanism to be operated from a locked to an unlocked state, of a properly bitted mechanical key and the generator of a digitally coded electrical command signal. The electrical command signal is transmitted through the lock to an actuator so that the lock, when enabled by insertion of the mechanical key, may be operated. The key may define a portion of the signal transmission path between the command signal generator and the actuator.
