How to Program a Cadillac Garage Door Opener

Cadillacs manufactured in recent years conveniently come equipped with a garage door opener sensor system built directly into the dash of the car.  This convenient system allows you to open your garage door without the need of a remote.  It is easily programmable and will operate any brand of garage door. 

1. Press and hold the two end buttons on your Cadillac HomeLink system. This will reset the garage door manufacturer codes and settings. Depending on the model of Cadillac, there may be a message about "Clearing Codes." Release the buttons when the "Codes Cleared" message appears or when the green light indicator flashes slowly.


2. Hold your original garage door opener up to the HomeLink system in your Cadillac. Press the button you want to assign to as the garage opener button on your HomeLink system and the open button on your original remote at the exact same time.


3. Release both of the buttons when either the green or red light flashes rapidly.


4. Press the button you assigned on your HomeLink system; if your garage door opens, you have successfully programed your Cadillac system to open your garage door.  If not, try repeating the above steps.

If repeating the above steps does not result in being able to open your garage door from the Cadillac system, you may need to reset your garage door motor. Most models will have a small reset sensor on the back of the system. Follow the manufacturer's instructions in order to do this. Be warned that if you reset the garage door motor, any other garage door openers may also need to be reset.
