Abstract

A vehicle electronic portable key system including a master key (11) and sub-key (12). A retainer (700 is arranged in the vehicle to retain the sub-key. A control unit (60, 90) determines whether the master key or sub-key is located in a vehicle interior or exterior wireless communicatable area (A; B). When the key is located in one of the wireless communicatable areas, the control unit permits various operations of the vehicle in accordance with the communicable area in which the key is located. The control unit determines that the sub-key is in a lent state if the sub-key is removed from the retainer when the master key is located in the interior wireless communicatable area. In a state in which the sub-key is located in one of the wireless communicatable areas after removal from the retainer, the control unit limits the operations of the vehicle unless the sub-key is determined as being in the lent state.
