Question
I HAVE A 1990 SEVILLE. THE STARTER WENT OUT SO I REPLACED IT. AFTER I HOOKED THE BATTERY UP AGAIN, I GOT THE MESSAGE "STARTING DISABLED DUE TO ANTI THEFT SYSTEM". IT STARTED AND RAN FINE BEFORE THE STARTER WENT OUT. THE CAR CAR CAME WITH TWO KEYS AND TRIED BOTH OF THEM THINKING IT MIGHT BE THE PASS SYSTEM. ANY HELP WOULD BE APPRECIATED. THX
Hi Pete,
These systems cause more problems for the owners and not thieves.
With this said, I will give you at least an idea of what you can do to fix your problem.
If everything is working properly, all you need to do is lock the door with the door button. Close the door and unlock it with the door key. That should set you up.
In the event that that does not work which it should, turn the ignition key on for 10 minutes. Turn off. Turn on for ten minutes. Turn off and turn on one more time.
These are the two reset procedures for GM.
Try the door lock first.
Good luck!

Expertise
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?
