Abstract
An anti-theft device, having application for preventing unauthorized operation of a vehicle, includes a moveable lock member biased toward the actuating member for the vehicle's parking brakes. An electric solenoid is energized along with the ignition system to retract the lock member and allow the parking brakes to be released. The preferred device also includes a timer apparatus that requires the parking brakes to be released according to a predetermined timing sequence in order to substantially prevent theft of the vehicle.
