Abstract: An apparatus and method for motor vehicle anti-theft wherein the apparatus comprises a device for blocking a motor vehicle's exhaust gases path and a device for moving the blocking device. The moving device moves or displaces the blocking device to one of a first position, whereat the blocking device is completely removed from an exhaust gases path, and a second position, whereat the blocking device completely blocks an exhaust gases path. The method comprises the steps of actuating the moving device and moving the blocking device to a position, whereat the blocking device completely blocks off or seals off a motor vehicle exhaust gases path.

Abstract: A remote-controlled anti-theft or theft-deterrent system and method, for motor vehicles, is disclosed which comprises a transmitting device, wherein the transmitting device is capable of transmitting data signals to at least two remote locations, a first receiving device for receiving the data signals transmitted from the transmitting device at a first of the at least two remote locations, a second receiving device for receiving the data signals transmitted from the transmitting device at a second of the at least two remote locations, a first control device associated with the first receiving device for processing the data representative of the data signals, wherein the first control device processes the data representative of the data signals and issues one of a disable signal and a re-enable signal to one of a vehicle's ignition system, a vehicle's fuel pump system and a vehicle's auxiliary equipment system one of instantaneously and after a time delay period, and a second control device associated with the
