Cadillac Repair/security


ok i'm not sure if you mean aftermarket secruity systems but when i start the car it shuts down stating that it's an anti-theft problem.  I tried using the key in the door and turning the ignition on for twenty minutes then trying to start all with the same results.  oh it's a 1997 cadillac eldorado my question is if i change the computer could this solve my problem.  as i stated in the beginning if this is not in your area of expertise i apologize for waisting your time


I need some more clarity. You state hen you start the car it shuts down. Do you mean the engine started and is running and then shuts down? Do you mean you tray to start and nothing happens?
You should have the VATS in that car with a big ugly resistor chip in the ignition key. Is that correct?

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
