Is your GMC key fob suddenly refusing to unlock your doors or start your vehicle? Don’t worry, you’re likely not facing a major car problem. In many cases, the culprit is simply a dead battery in your key fob. The good news is that replacing the battery in your GMC key fob is a straightforward task you can easily handle yourself, saving you time and a trip to the dealership for a minor issue. Most GMC key fobs are powered by a common and readily available 3-volt CR2032 battery, designed to last for several years under normal use. When the time comes for a replacement, you’ll be pleased to know it only requires a few minutes and minimal tools.
To get your GMC key fob working like new again, here’s what you’ll need and how to replace the battery:
What You’ll Need for a GMC Key Fob Battery Replacement
Before you begin, gather these simple tools and supplies:
- A new CR2032 Battery: You can purchase these batteries at most drugstores, supermarkets, hardware stores, and online retailers. Consider buying a multi-pack to have spares on hand for future replacements.
- A Flathead Screwdriver: A small, flathead screwdriver will be needed to gently pry open the key fob casing.

Step-by-Step Guide to Replacing Your GMC Key Fob Battery
Follow these easy steps to replace the battery in your GMC key fob:
-
Open the Key Fob Casing: Locate the small slot on your GMC key fob. Using your flathead screwdriver, gently insert the tip into the slot and carefully twist. This should start to separate the two halves of the key fob. Work your way around the seam, gently prying until the back panel of the key fob pops off. Avoid using excessive force to prevent damage to the casing.
-
Remove the Old Battery: Once the key fob is open, you’ll see the battery. Take note of the battery’s orientation – specifically, observe whether the positive (+) side is facing up or down. This is crucial for installing the new battery correctly. You may be able to gently pry out the old battery with your fingertip, or use the flathead screwdriver to carefully nudge it out if it’s tightly fitted.
-
Insert the New Battery: Take your new CR2032 battery and install it in the key fob, ensuring the positive (+) side is facing in the same direction as the old battery was removed. Push the new battery firmly into place until it is securely seated in the battery compartment.
-
Close the Key Fob: Carefully align the two halves of the GMC key fob casing. Press them firmly together until they snap back into place. Ensure that the casing is completely closed and there are no gaps.
Testing Your GMC Key Fob After Battery Replacement
After replacing the battery and reassembling your key fob, test it to ensure it’s working correctly. Try locking and unlocking your doors remotely, activating the panic button, and starting your vehicle (if your key fob has remote start functionality). In most cases, a fresh battery will resolve the issue, and your GMC key fob should be functioning perfectly again.
However, if your GMC key fob still doesn’t work after replacing the battery, there might be another underlying issue. It’s possible there could be a problem with the key fob itself or your vehicle’s electronic system. If you suspect a more complex issue, we recommend contacting our dealership to schedule a service appointment. Our certified technicians can diagnose the problem and provide the necessary repairs to get you back on the road with a fully functional key fob.
