Abstract: An identification or protection system for vehicles, doors, lights and other electronic objects possessing a disabled state, having a disabling circuit operatively associated with the identification system so that when said resulting circuit is activated, the object achieves its disabled state; a transmitter transmitting a signal for a period of time at least once during a succession of time intervals using frequency-based coding; a receiver configured to receive the signal transmitted by the transmitter, the receiver causing the disabling circuit to disable the object when the receiver does not receive a number of consecutive signals from said transmitter which exceeds a pre-determined threshold.
