Cadillac Repair/Cadillac Seville keyless entry system

Question
Hello,
I recently bought Seville, which was first registered in Germany Feb.1998, so its most probably a 1997-model. I did not receive the keyless entry device with the car. I want to buy a new device via the internet in the USA. Question is: how to program the new device to my car? Here in Germany, it`s not so easy to find a Cadillac expert. The only garage, I had the chance to talk to, offered me a new device for 180 Euro (approx. 250 $US)and the programming for additional 300$.
I really appreciate any better way to solve the problem.

I also still have in my possession the entry "beeper" of my old 1994 Eldorado, the car which I scraped recently. Might it be possible, do program this device to my car?

Thank You very much in advance
Ralf

Answer
Hello,

Hopefully, you still have the owners manual for the car in the glovebox. The owner's manual gives you instructions as to how to program the key fob. As far as the fob working from the Eldo, I doubt it, but you can try.

Good luck.

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?
