<p>The present invention comprises a security locking system for use in the locking of a door or doors of a motor vehicle (2) to prevent unauthorised entry into the vehicle. The system comprises an electrical circuit (1) comprising at least one electrically operable solenoid having a first and second coil (4, 3) located within each of the doors of the vehicle. An energisation source (9) is linked to the solenoid or solenoids. The circuit has momentary switches (8a, 10a) for isolation of said solenoid or solenoids from the energisation source (9). The solenoid or solenoids also has associated with the first and second coils (4, 3) a first and second plunger (5, 6) which are each linked to a locking mechanism in said door so as to enable the locking mechanism to move between an engaged and disengaged position when said plunger is moved between an advanced and retracted position in response to energisation from said energisation source, wherein when said first coil (4) is activated, said plunger (6) advances to lock said door and when said second coil (3) is activated said plunger (5) retracts to unlock said doors; said door or doors having keyway access means eliminated therefrom.</p> |
