Question
Hello, Mr. Painter.

My only car is a 1992 Cadillac Seville with 93,100 miles. Although 21 years old, the exterior is good. The interior is worn.

Exactly one week ago I drove it to the mechanic's shop that has worked on my car for ten years. They fixed the problem (straining sound)) when turning the steering wheel, with fluid and a pump. However, when they turned the key to start the car out of their garage, the car responded with the anti-theft warning. They pondered the problem and went to Radio Shack to get a VAT bypass kit but that did not work. They tried both keys, neither worked. The mechanic suggested towing it to the Cadillac shop but instead I discreetly called the dealership to ask what the problem could be. "Sounds like a transponder problem that will cost you $580." The mechanic and I thought that was too costly so I called an Auto Locksmith who was kind to offer his suggestions to the mechanic over the phone, since neither key worked and said maybe the wires behind the dashboard or the fuses. Meanwhile, my mechanic's company offered to pay on a rental car for me while they worked on my car. I didn't accept their offer because helping them may also help me. Tomorrow (seventh day) they are expecting new keys for my car. I am hoping this solves the problem completely. If not, "What could it be?" and the estimated "Cost?"

Thank you for your time.

Hi,

How ignorant can the dealer be? Transponders were not offered in this model until 2000. In over ten years, I have not heard a knowledgeable response from a dealer. All I get is complaints about the dealers replacing parts and not fixing the problem. Good thing you never took the car to the dealer.

Sounds like your mechanic is a stand up guy and really cares for you--rare!

It's very possible that since this is not the mechanics expertise with bypassing the system, its very possible that he misread the value or has a bad connection. I am sure he is good at what he does, but this bypass can be touchy. What was the message on the dash? Vehicle may not start in 3 minutes? The computer could have failed as well. If that is the case, the bypass would not work anyway.

I wish you would have contacted me before doing the resistor bypass. I don't understand the reason for ordering keys at this point because the system is already bypassed.

I have never seen a resistor key fail, unless the resistor fell out and was missing. Keep in mind I have been involved in thousands of these situations.

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?
