1. An anti-theft system for motor vehicles, comprising:

  • at least one inhibitor in a disc rotor of at least one wheel of a motor vehicle;

    at least one locking member that can be inserted into at least one inhibitor to prevent at least one wheel from turning; and

    at least one solenoid that, when energized, causes at least one locking member to be inserted into at least one inhibitor, and when de-energized, causes at least one locking member to be withdrawn from at least one inhibitor;

    wherein at least one of the inhibitors in at least one of the disc rotors is an arcuate recess;

    there are a plurality of the inhibitors in at least one of the disc rotors, and the inhibitors are an equal distance from the center of the wheel;

    the inhibitors in at least one of the disc rotors are arranged in a circular pattern around a center of the wheel;

    the inhibitors in at least one of the disc rotors are separated by obstructions;

    there are four obstructions arranged at right angles;

    at least one solenoid is energized when an activation code is entered;

    at least one solenoid is de-energized when a deactivation code is entered;

    the activation code and the deactivation code are entered using a keypad;

    at least one locking member is cylindrical;

    means are included for locking at least one brake of the vehicle when the activation code is entered;

    means are included for releasing at least one brake when the deactivation code is entered;

    at least one brake is locked by preventing release of a cable attached to a lever controlling the brake;

    when the activation code is entered, an additional solenoid is energized that causes a clamp to engage a cable inhibitor that prevents release of the cable and the lever; and

    when the deactivation code is entered, the additional solenoid is de-energized, causing the clamp to disengage the cable inhibitor, and allowing release of the cable and the lever.
