well,,,you can try ebay,,,, its called "blackjax4" made by clifford it is like two systems in one,,,,its a stand alone system that works by itself or with any alarm system..

it is a car jack system,, door opens it activates the car jack feature.. but when you turn the ignition off to go home or to park the car,,, it automatically shuts down the entire ignition system.. meaning the car will not turn over or crank the starter...


sells on ebay at buy it now for like 89.00 the system sells for over 200.00 at stores... i dont work for them or anything but i have tested the system and it works great,,, plus you get the car jack feature too....and it comes with a siren and everything....

just my 2cents
