  • Vehicle security device using key device which completes interrupted circuits
    Patent number: 5594284
    Abstract: A vehicle security system disables various electrical systems throughout the vehicle. A unique double-sided security key is used to complete the various circuits of the chosen electrical systems by matching physical codes on the key to that of an installed receiving unit mounted within or about the dashboard of a vehicle. The various combinations created by the coded key make a determination of how the various circuits are broken. The method of attempting to re-connect the circuits by trial and error is prohibitive to a would-be thief. The unit can be used to disable an automobile, boat, motorcycle, RV, etc. The device may include one or more blocking diodes within the circuits to produce false readings during attempted tampering.
