It only takes a moment to learn how to program your 2021 GMC garage door opener. Just park close to your garage door and have your current garage door remote handy.
Your GMC garage opener, also known as the HomeLink garage opener, allows you to open three separate garage doors from within your car.
Here’s how to program yours:
  • Choose which of the three HomeLink buttons you want to program and hold it down. A red light should begin to blink.
  • Hold your garage remote a few inches from the HomeLink.
  • Press the opener button until the red light becomes solid.
That should do it! If you’re having trouble, just make sure you’re parked close enough to the garage in question (without being over the sensor).
