Abstract:
    The invention easily specifies a position of a lost electronic key. A control device 2 having an immobilizer function is equipped with a transmitting circuit 202 sending out a request signal to a predetermined range. After a response signal to the request signal is temporarily received from an electronic key 1 to move a moving element, when the response signal to the request signal periodically sent out is not received, it is determined that the electronic key 1 is out of a transmitting performance range of the transmitting circuit 202, namely dropped. A monitoring portion 220 energizes a warning light 217 by outputting a warning signal at that time, and transmits the warning signal to a navigation device 3 too. The navigation device 3 responds to the warning signal and memorizes a position at that time as electronic key position information, and displays a key position on the basis of the electronic key position information on a map simultaneously or according to a separated instruction.
