Abstract
Abstract A car theft proofing system includes a sensor attached to or mounted adjacent a cylinder door lock for detecting insertion into the door lock of a door key or other article, an alarm device for giving an alarm, an alarm drive device for driving the alarm device, a control unit for causing the alarm device to give the alarm in response to signals received from the sensor and the alarm drive device, and a radio transmitter for transmitting a radio wave upon insertion of the article. The alarm drive device includes a portable remote control transmitter and a receiver disposed on a car body. The remote control transmitter includes an abnormality alarm for transmitting a theft signal in response to the radio wave transmitted from the radio transmitter.
