Is your GMC key fob suddenly refusing to unlock your doors or start your vehicle? Don’t worry, you’re likely facing a common issue: a dead battery. Fortunately, replacing the battery in your GMC key fob is a straightforward task that you can easily handle yourself. This guide will walk you through the simple steps to get your key fob working again in no time.
Changing the battery in your GMC key fob is a much simpler process than you might imagine. Most GMC key fobs are powered by a small, easily replaceable 3-volt CR2032 battery. These batteries are designed to last for several years, typically three to four, but eventually, they will need to be replaced. When that time comes, you won’t need to visit a dealership or professional mechanic. With just a few minutes and a common household tool, you can restore full functionality to your key fob.
Here’s what you’ll need to change your GMC key fob battery:
- A new CR2032 battery: You can purchase these batteries at most drug stores, supermarkets, hardware stores, and online retailers. Consider buying a multi-pack to have spares on hand for future replacements.
- A small flathead screwdriver: This will be used to gently pry open the key fob casing.
Once you have gathered these simple tools, follow these steps to replace your GMC key fob battery:
- Locate the small notch on your GMC key fob. This notch is usually found along the side of the key fob casing.
- Carefully insert the flathead screwdriver into the notch. Gently twist the screwdriver to pry the two halves of the key fob casing apart. Avoid using excessive force, as you could damage the casing. The case should pop open with minimal effort.
- With the key fob open, locate the battery. Take note of the orientation of the old battery before removing it. Observe which side is facing up (usually the positive side with the “+” symbol). This will ensure you install the new battery correctly.
- Remove the old battery. You may be able to gently pry it out with your fingertip or the edge of the screwdriver if needed.
- Insert the new CR2032 battery. Make sure the positive (+) side of the battery is facing the same direction as the old battery was.
- Carefully snap the two halves of the key fob casing back together. Press firmly until you hear or feel the case click securely closed.
After replacing the battery, your GMC key fob should now be working correctly. Test all the buttons to ensure they are functioning as expected, including locking and unlocking the doors, remote start (if applicable), and the panic button.
In the vast majority of cases, replacing the battery will solve the issue of a non-working GMC key fob. However, if you’ve replaced the battery and your key fob still isn’t functioning, there might be a more complex issue. In such instances, it’s advisable to consult with a qualified automotive technician or your local GMC dealership for further diagnosis and potential repairs. They can help determine if there’s a problem with the key fob itself or your vehicle’s receiver system.
