A vehicle electronic key system (1) that may be lent to a third person without having to worry about how the key (12) would be used. The key system includes a portable key (12) and a control unit (4) installed in a vehicle (3). When the vehicle owner does not want the third person to use a certain accessory, the owner registers a restriction code in the key. The restriction code is registered only when a fingerprint input from an input device matches the owner's fingerprint that is pre-registered in the key. The registration of the restriction code prohibits operation of the accessory. <IMAGE> |
