ABSTRACT: An anti-theft device for an automotive vehicle in which the starter is grounded to the vehicle frame unless two switches are maipulated by the user. One switch is the key- operated ignition switch. The second switch is connected to an electrical relay to open one side of the grounded starter to turn over the engine. In one embodiment, the second switch is a sensor located in a hidden place in the vehicle. In another embodiment, the second switch is connected between the battery and an electrical accessory that is energized independently of the position of the ignition switch, such as a power-operated lock, a brake-operated switch or the like. The user must energize the second switch in order to open the connection between the starter and the ground before he can energize the starter by manipulating the key in the ignition switch. In another embodiment of the invention, both sides of the ignition coil and the starter are normally grounded to the frame. Both can be energized only after the second switch is manipulated. The ignition switch is connected to a siren that is energized if the ignition switch is manipulated but the second switch is not, as by a thief.
