Is your GMC key fob not working like it used to? The most common culprit is a dead battery. Fortunately, replacing the battery in your GMC key fob is a straightforward task you can easily handle at home. Most GMC key fobs use a 3-volt CR2032 battery, which typically lasts for 3 to 4 years. When it’s time for a change, you’ll only need a couple of simple tools and a few minutes.
To replace the battery, you will need the following items:
- A new CR2032 battery
- A small flathead screwdriver
Once you have gathered these items, follow these simple steps to replace your GMC key fob battery:
-
Open the Key Fob Casing: Locate the small slot on the back of your GMC key fob. Using your flathead screwdriver, gently pry open the back panel. Be careful not to apply excessive force, as you could damage the casing. The panel should pop off relatively easily.
-
Remove the Old Battery: With the key fob open, you’ll see the CR2032 battery. Take note of the battery’s orientation, specifically which side is facing up (positive or negative). This is important for installing the new battery correctly. Carefully remove the old battery. You might be able to gently pry it out with the flathead screwdriver if needed, but often you can remove it with your finger.
-
Insert the New Battery: Place the new CR2032 battery into the key fob compartment. Ensure the new battery is oriented in the same direction as the old one you just removed (positive side up or down, as noted earlier).
-
Close the Key Fob: Carefully align the two halves of the key fob casing and snap them back together. Ensure they are securely closed.
In most cases, replacing the battery will restore your GMC key fob to its working condition. If your key fob still doesn’t work after replacing the battery, there might be a different issue. It could be a problem with the key fob itself or your vehicle’s electronic system. If you continue to experience problems, it’s recommended to contact a qualified service technician or your GMC dealership for further diagnosis and repair. They can help determine if there are more complex issues with your key fob or vehicle.
