Abstract
Abstract Tamper-resistant features are provided for a vehicle hood-locking and ignition disabling apparatus which functions as an automotive anti-theft device. These tamper resistant features are responsive to efforts to defeat or by-pass the anti-theft device and comprise: 1. a magnetically-operated alarm; 2. a lock "breakaway" portion responsive to efforts to break or pull the lock portion of anti-theft device; and 3. an underhood dead latch assembly adapted to dead-bolt the hood of the vehicle in a closed position, and to latch the ignition-disabling circuitry in a closed position.
