The present invention relates to an electronic key (23) for controlling a remote access system, (5) in a vehicle (3), such as a PEPS, PASE or RKE system. The electronic key has an electronic controller (29), a first receiver (25) for receiving an authentication signal, and a first transmitter (25) for transmitting a signal. The electronic key further comprises a data connector (31) for establishing a wired connection with a data port (33, 43) on the vehicle. Power may also be transferred between the electronic key and the remote access system when the key is docked in the data port. A challenge-response authentication procedure may be conducted when the electronic key is inserted into the data port. Data ports may be provided on the exterior of the vehicle, for granting entry to the vehicle, and interior of the vehicle, for controlling engine start after an authentication process. The vehicle has a controller, transmitter and receiver, for exchanging authentication signals with the electronic key and controlling access to the vehicle, in addition to the data ports. The direct wired connection between the key and the vehicle remote access system provides a back-up when wireless communication is not possible. |
