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

An air pressure information display device of a vehicle tire has a normal air pressure storage module () for storing a normal air pressure of a tire corresponding to a tire temperature, an excessive/deficient amount detection module () for detecting the excessive/deficient amount from the normal air pressure on the basis of the stored normal air pressure, and air pressure information detected by an air pressure information detection module (), and a display control module () for controlling a display () to display the detected excessive/deficient amount. Hence, since the user is informed of the excessive/deficient amount from the normal air pressure, he or she can appropriately determine an air pressure state of a tire even when he or she does not recognize the normal air pressure.

An air pressure warning device of a vehicle tire has an excessive/deficient amount calculation module ( ) for calculating an excessive/deficient amount on the basis of the difference between a normal air pressure stored in a normal air pressure storage module ( ) and a detected tire air pressure, an informing control module ( ) for controlling an informing module ( ) to inform an excessive/deficient state of the tire air pressure determined based on the calculated excessive/deficient amount, and a normal air pressure correction module for increasing the readout normal air pressure by a predetermined value when an expressway traveling detection module ( ) detects that the vehicle is on an expressway.

An anti-vehicle-thief apparatus registers specific ID codes of a plurality of keys, and determines validity of a key, for example, in accordance with an operation of the key 1 including a transponder having one of the registered specific ID codes. The anti-vehicle-thief apparatus registers a code specific to the key and confirms an operation in which an ignition switch is turned on and off five times by using the key, where this operation is for changing the ID codes specific to the plurality of keys registered in EEPROMs. After the confirmation of the operation, ID codes specific to a plurality of new keys are successively registered, thereby preventing a third person from using the old keys, as well as making registration of the ID codes specific to the new keys easily.
