Put key remote near the ignition switch. Disconnect the battery for 30 minutes and reconnect. It SHOULD reset the chip in the ignition to match the remote and they should then be recognised by the ECM.
need to reset the sensitivity level of the alarm system..some vehicles have a sensor that will set off if the car is bumped or shakes in the wind..reset it for sensitivity or replace it with a new one..
Hello: The keyless entry feature was NOT a factory option available on the 1989 Cadillac SedandeVille. If you have keyless entry it has to be after market. you will have to find out who made the add on unit and how to program it. SORRY
press the two outside buttons at the same time. Hold while message reads "clearing codes"
Once you get a cleared message. hold the button that you want to program as your remote and press it down. The light will flash slowly. Take your remote in your other hand and hold it about 3 inches from your review mirror as close to the windsheild as possible. You must do this as soon as you press your designated button on the panel. Hold until your green light starts flashing fast. Once it flashes fast it means you have programmed your button properly.
Suggestions - do not do this in front of your garage as you remote will make you door go up and down the whole time. Also - make sure your batteries are new in your remote so you get a good signal to your button. Last thing - if one remote does not work after a couple of tries - use another remote.
