Abstract: Disclosed is a burglar sensor arrangement structure for arranging, with respect to a vehicle interior member (10), a burglar sensor configured to detect an intrusion into a vehicle interior. The burglar sensor arrangement structure comprises an ultrasonic wave generation unit (2) for generating an ultrasonic wave, and a throat portion (18) for radiating the ultrasonic wave generated in the ultrasonic wave generation unit, from a outside opening (18a) thereof into the vehicle interior, wherein the vehicle interior member is formed with a groove (20), and the outside opening of the throat portion is opened at a bottom surface of the groove.

Abstract: Disclosed is an electronic key system which comprises a vehicle-mounted device and a plurality of electronic keys, and is configured to have: a normal mode in which a given processing is permitted to be executed by the vehicle-mounted device when a given wireless communication processing between the vehicle-mounted device and any one of the plurality of electronic keys is successfully completed; and a deactivated mode in which the given processing is inhibited from being executed by the vehicle-mounted device. The vehicle-mounted device is configured not to execute, in the deactivated mode, the given processing even when receiving an RF signal after transmitting an LF signal, during the given wireless communication processing, and the one electronic key is configured not to transmit, in the deactivated mode, the RF signal even when receiving the LF signal, during the given wireless communication processing.
