Abstract
Abstract Disclosed herein is a system whereby a car burglar can be prevented while a driver leaves a car as engine going. Upon detection of the driver getting off the car as engine idling, a predetermined device other than equipment belonging to an engine starting system is actuated to a state not ready for the car to start. The device is then turned to a state ready for the car to restart through a predetermined enciphered operation.
