Abstract
An electronic key for use with a vehicle locking system controls at least one of a door locking feature and an ignition lock feature on the vehicle. The electronic key has a transmitter/receiver for transmitting at least one coded operating signal generated by the electronic key and transmitted from the electronic key to the locking system to activate at least one function of the locking system upon positive evaluation of the transmitted operating signal by the locking system. Actuating members are provided on the key and operated by the user to cause the transmitter/receiver to transmit the coded operating signal, and the activating elements are also adapted for the user to enter an individual code. A circuit is provided for receiving the entered individual code and comparing it with a programmed individual code and, upon entry of the programmed individual code being detected, changing the key over from a first, activated state in which transmission of the coded operating signal is prevented to a second, inactivated state in which transmission of the coded operating signal is permitted.
