Abstract

A device for disabling a motor vehicle having an engine, an engine compartment, a hood, a primary circuit enabling the operation of the engine and a power source. The device includes a remote receiver having a pair of remote controlled switches which are controlled between contact and open positions by a remote transmitter. The device connects one of the switches with a primary circuit with the switch normally in a contact position maintaining the power circuit normally complete. A secondary electrical circuit which controls electrically actuated hood locks is also provided. Second switches of the remote receiver are connected in the secondary circuit with the second switches being normally open which maintains the secondary circuit normally broken. A remote transmitter which when actuated causes the remote receiver to move the first switch to an open position breaking the primary circuit and disabling the engine and to move the second switch to a closed position enabling the secondary circuit to activate the hood locks to lock the closed hood.
