ABSTRACT:
A system for the prevention of theft of a motor vehicle comprising a valve system and electronic package for the control thereof. The valve system is connected between the master cylinder and the slave cylinder of the vehicle brake system and is selectively actuatable to cause the brakes of the vehicle to lock when the vehicle's ignition is turned off. The electronic package is connected to the valve system and the ignition system for generating an alarm system for generating an alarm system for selectively actuating the valve system. A keyboard is connected to the electronic package for controlling the operation thereof and means are provided for receiving a multi-digit code in the keyboard to effect actuation and deactuation of the valve system and the release of the vehicle brakes for operation of the vehicle. A series of separate alarm sensors are provided in conjunction with the electronic package for affording added safety and theft deterrence. In addition a manual override valve is incorporated into the system to facilitate emergency deactivation as well as disengagement of the system for vehicle repair and the like.
