Abstract: An anti-theft system for motor vehicles. The preferred embodiment is designed to prevent theft by preventing a vehicle's wheels from turning when the system is activated. In the preferred embodiment, there are inhibitors in the disc rotors of each wheel. Next to each wheel, there is a solenoid, within which is a locking pin or piston rod. When the user enters an activation coded key in an ignition, the solenoids are energized, causing the piston rods to move outward into arcuate recesses, thus preventing the rotor discs from turning. A deactivation code must be entered in the ignition to de-energize the solenoids, causing the piston rods to move back into the solenoids and releasing the rotor discs. Optionally, the parking brake may also be locked when the system is activated.

The preferred embodiment is designed to prevent theft by preventing a vehicle's wheels from turning when the system is activated. In the preferred embodiment, there are inhibitors in the disc rotors of each wheel. Next to each wheel, there is a solenoid, within which is a locking pin or piston rod. When the user enters an activation coded key in an ignition, the solenoids are energized, causing the piston rods to move outward into the curved slots, thus preventing the rotor discs from turning. A deactivation code must be entered in the ignition to de-energize the solenoids, causing the piston rods to move back into the solenoids and releasing the rotor discs. Optionally, the parking brake may also be locked when the system is activated.
