How do you program the garage door opener on a 2021 GMC Sierra?
I just purchased a new 2021 GMC Sierra and I know that I’m able to link my car to my garage door opener, but I’m not sure where to start. Do you know how to program the garage door opener on a 2021 GMC Sierra?

, follow these simple steps: - Press and hold the outer two HomeLink buttons on your GMC Sierra, found on the roof control center between the driver and passenger seats
- Hold these buttons until the small red light between the buttons changes from solid to rapid flashing. Once the light flashes, stop pressing the buttons
- Then, press and hold the HomeLink button you’d like to use for your garage door
- Hold your garage door remote button 1-3 inches away from the HomeLink button while also pressing and holding the HomeLink button
- Do not release either button until the red button stops flashing slowly and returns to a solid red light
- Then, press the HomeLink button you used throughout the process to link your garage door. Now, you should be able to open and close your garage door with your GMC HomeLink button
