Understanding Your Key Fob
Your 2017 GMC Sierra key fob is essentially a tiny communication device that allows you to unlock, lock, start, and sometimes even remote-control your vehicle. The process of programming this key fob can be as simple as replacing a dead battery, or it may involve more intricate steps depending on the specific features of your Sierra.
