A communication monitoring unit monitors whether or not radio waves Swk periodically transmitted from a vehicle are received. When there is no movement of the portable electronic key device but the portable electronic key device has received or is receiving radio waves from the vehicle, an operation controller maintains the start-up state of the portable electronic key device.
