Abstract
A vehicle theft prevention system switches an engine from an immobilized state to a mobilized state when an ID code received from a mobile device carried by a user matches an ID code registered in advance, and keeps the engine in the immobilized state when the ID code received from the mobile device does not match the ID code registered in advance. Further, when a disable command is received from the center and it is detected that the vehicle is in an unused state based on a state of a predetermined signal indicative of states of the vehicle, the system immobilizes the engine and prevents the engine from being switched from the established immobilized state to a mobilized state even if the ID code included in the signal received from the mobile device matches the ID code registered in advance by invalidating the ID code of the mobile device.
