Abstract:
A vehicle electronic key comprises: a receiver (21) for receiving a request signal sent by an on-board device; a transmitter (22) to transmit a response signal to respond to the request signal; a key control unit (26) to determine whether the request signal was received and to cause the response signal to be sent from the transmitter on the basis of the determination that the request signal has been received; and an acceleration sensor (25) to detect acceleration occurring in the vehicle electronic key and to set a vibration detection flag on the basis of the determination that a vibration of a threshold or greater has been detected. The key control unit sets a response permission state to respond to the request signal on the basis that the vibration detection flag is set.
