Is the light on all the time? Or only when you turn the car off? Is it solid on all the time? Or blinking? You will need a scanner if you don't have one to diagnose the problem, let me know if you have one, (if you don't we sell them on this site) and I will step you through the procedure called "diagnostic system check -- theft Deterrent"
