Understanding Your GMC Key Fob Battery
When it comes to your GMC vehicle, the key fob plays a vital role in convenience and functionality. It allows you to lock and unlock your doors, start your engine remotely, and often even open your trunk with just a click. However, like all electronic devices, the key fob requires power to function, which comes from a small component called a battery.

- CR2450: Found in some newer key fobs that require a larger power source for additional functions.
- CR123A: Occasionally used in fobs with advanced features such as keyless entry and ignition.
To determine the exact type of battery needed, you can check your user manual or look inside the key fob after you open it.
Signs Your GMC Key Fob Battery Needs Replacement

- Inconsistent Functionality: If the key fob only works sometimes or requires multiple button presses to function, it may be time for a change.
