Like any electronic device, your GMC key fob relies on a battery to function, and eventually, this battery will need replacing. The most common culprit for a GMC key fob suddenly ceasing to work is a dead battery. Typically, these fobs use a 3-volt CR2032 battery, designed to last around three to four years under normal use. The good news is replacing it is a straightforward task you can easily handle yourself with just a couple of simple tools. You won’t need to be a car expert to get this done!
To change the battery in your GMC key fob, you will need:
- A small flathead screwdriver
- A new CR2032 battery
These batteries are widely available and can be purchased at most stores that sell batteries, including department stores and hardware stores. Consider buying a multi-pack to have spares on hand for the future.
The process of replacing the battery is as follows:
Step 1: Open the Key Fob
Locate the small slot on the back of your GMC key fob. This slot is designed to allow you to gently pry open the fob casing. Insert the tip of your flathead screwdriver into this slot. Apply gentle pressure and twist the screwdriver to separate the back panel from the front. Be careful not to apply excessive force, as you could damage the plastic casing. The key fob should pop open relatively easily.

Step 2: Remove the Old Battery
Once the key fob is open, you’ll see the battery compartment. Take note of the orientation of the old battery before removing it – specifically, observe whether the positive (+) side is facing up or down. This will ensure you insert the new battery correctly. You can usually pry the old battery out gently with your fingertip or the edge of the flathead screwdriver if needed.

Step 3: Insert the New Battery
Take your new CR2032 battery and insert it into the battery compartment, matching the orientation you noted in the previous step. Most often, the positive side of the battery will face towards the back cover of the key fob. Press down gently to ensure the battery is securely seated in place.

Step 4: Close the Key Fob
With the new battery in place, carefully align the two halves of the GMC key fob casing. Press them firmly together until they snap securely back into place. You should hear a click indicating that the fob is properly closed.

In most cases, replacing the battery will restore your GMC key fob to full working order. However, if your key fob still doesn’t function after a battery change, there might be a more complex issue with either the key fob itself or your vehicle’s electronic system. If you continue to experience problems, it’s recommended to contact a certified GMC dealership to diagnose and resolve any underlying issues. They can provide expert assistance to ensure your key fob and vehicle electronics are working correctly.
