Experiencing issues with your 2020 GMC Sierra key fob? It can be frustrating when your key fob suddenly stops working, leaving you unable to remotely lock, unlock, or start your vehicle. The most frequent culprit behind a dead key fob is a simple issue: a dead battery. Fortunately, replacing the battery in your 2020 GMC Sierra key fob is a straightforward process you can easily handle yourself.
Most GMC Sierra key fobs, including those for the 2020 model, are powered by a 3-volt CR2032 battery. These batteries are designed to last for several years, typically three to four, under normal usage. However, factors like frequency of use and environmental conditions can affect battery life. When the time comes for a replacement, you won’t need to visit a dealership immediately. With just a few minutes and the right replacement battery, you can restore full functionality to your key fob.
To perform this quick fix, you’ll only need a couple of common household items: a small flathead screwdriver and a fresh CR2032 battery. These batteries are widely available at most drugstores, supermarkets, and auto parts stores. Buying them in multi-packs can be a cost-effective way to have spares on hand for future replacements.
The first step in replacing your 2020 Gmc Sierra Key Fob Battery is to open the key fob casing. Locate the small notch on the side or bottom of your key fob. Using your flathead screwdriver, gently insert the tip into the notch and carefully pry the two halves of the key fob apart. Avoid using excessive force, as you could damage the casing. The key fob is designed to snap open with minimal pressure.
Once the key fob is open, you’ll see the battery compartment. Take note of the battery orientation before removing the old battery. Observe whether the positive (+) side is facing upwards or downwards. Typically, the positive side is facing up towards the back cover of the key fob. This is crucial for correct installation of the new battery.
Carefully remove the old CR2032 battery. You can use the tip of your screwdriver to gently nudge it out if necessary. Now, take your new CR2032 battery and install it in the same orientation as the old one. Ensure it is securely placed in the compartment.
After inserting the new battery, carefully align the two halves of the key fob casing. Press them firmly together until they snap back into place. You should hear a click indicating that the case is securely closed.
In most cases, replacing the battery will solve the issue, and your 2020 GMC Sierra key fob should now work perfectly. Test all the buttons to ensure proper functionality – lock, unlock, remote start, and panic button.
However, if you’ve replaced the battery and your 2020 GMC Sierra key fob still isn’t working, there might be another underlying problem. This could involve issues with the key fob itself or your vehicle’s receiver system. In such instances, it’s best to seek professional assistance. Consider contacting a certified GMC technician or your local GMC dealership to diagnose and resolve any more complex issues. They have the expertise and equipment to identify whether the problem lies within the key fob or the vehicle’s electronic system. Don’t hesitate to contact our dealership for an appointment to have your key fob or vehicle checked if you continue to experience problems after a battery replacement.
