Leave key in ignition and turn to ON (do not start) Leave in on position for exactly 10 minutes. After 10 minutes is up and your anti-theft light is off, then immediately start the car.
Sometimes the key also need to be reprogrammed for the car.
insert the key and turn the key to "on". The DIC will say "Remove Key, Starting Disabled", and the security light will remain on.

approx. 10 minutes later. Remove the key. wait 10 seconds and repeat this another two times, for a total of 30 minutes "key-in" time.

Now insert your key and start the engine.

To learn additional keys:
Start the engine up with a working key. Shut the engine off, and within 10 seconds, insert the next key you want to learn and turn it to "ON". When the security light goes out, that key is programmed. Repeat for the next key, up to 10 keys can be programmed per car.

Testimonial: "Worked exactly like you said, thanks a million."

Hello: On the rear bumper, driver side lower portion you will see a square which you can flip open with the key you have. Once open you will see a lock cylinder, insert the key and turn. That will open the trunk. Inside the trunk you will see a handle, pull it and it will open the drivers door. That should do it.

Reset 98 cadillac catera alarm

You can get one from the dealer or on ebay.
I would recommend an aftermarket unit with car starter. Much cheaper, 2 remotes and starts the car as well.
