Integrated garage door automation and wireless signal transmission on the 2023 GMC are managed by Universal HomeLink transceiver modules, overhead console buttons, and garage motor programming protocols.
How to Fix It:
-
Clear Memory: Press and hold the two outer HomeLink buttons on your overhead console for twenty seconds until the indicator light flashes slowly.
-
Train the Button: Hold your handheld garage remote close to the mirror buttons and press both the remote and the desired vehicle button simultaneously until the light flashes rapidly.
-
Sync Rolling Codes: Press the Learn button on your garage door opener motor in your home, then press your vehicle's programmed button twice to complete synchronization.
