Is your GMC key fob refusing to unlock your doors or start your vehicle? Don’t worry, you’re likely facing a common issue: a dead battery. Like all batteries, the one in your GMC key fob will eventually need replacing. Fortunately, changing the battery in a GMC key fob is a straightforward process that you can easily handle yourself at home, saving you time and a trip to the dealership for this minor issue. Most GMC models, from trucks like the Sierra to SUVs like the Yukon and Terrain, use a common type of battery in their key fobs.
The good news is that replacing the battery on your GMC key fob requires minimal tools and only a few minutes of your time. Typically, GMC key fobs are powered by a 3-volt CR2032 battery, known for its longevity, usually lasting between three to four years under normal use. When the time comes for a replacement, you won’t need to search far and wide. These CR2032 batteries are readily available at most department stores, hardware stores, and even pharmacies where batteries are sold. You might consider purchasing a multi-pack to have spare batteries on hand for future replacements.
To replace the battery, you will need just one simple tool: a flathead screwdriver. Here’s a step-by-step guide to help you through the process:
Step 1: Open the GMC Key Fob Casing
Carefully inspect your GMC key fob. You’ll notice a small seam running along the edge where the two halves of the fob meet. This is where you’ll use the flathead screwdriver. Gently insert the tip of the flathead screwdriver into this seam. Apply a slight twisting motion to carefully pry the back panel of the key fob open. Avoid using excessive force, as you want to open the casing without damaging the plastic. The panel should pop open with a little gentle pressure.
Step 2: Remove and Replace the Old Battery
Once the key fob is open, you’ll see the battery compartment. Take a moment to observe the orientation of the old battery before removing it. Note whether the positive (+) side is facing upwards or downwards. In most GMC key fobs, the positive side of the battery faces towards the back panel of the fob. This is crucial for correct installation of the new battery. Carefully remove the old battery. Now, take your new CR2032 battery and insert it into the compartment, ensuring the positive side is facing in the same direction as the old battery was.
Step 3: Reassemble the Key Fob
With the new battery securely in place, it’s time to close up the key fob. Align the two halves of the key fob casing, making sure they fit together properly. Press firmly until you hear or feel the case snap back together. Ensure that the casing is completely closed and secure.
Step 4: Test Your Key Fob
Now that you’ve replaced the battery, test your GMC key fob to ensure it’s working correctly. Try locking and unlocking your doors remotely, and if your vehicle has remote start, test that function as well. In most cases, replacing the battery will restore your key fob to full working order.
However, if you find that your GMC key fob is still not functioning after replacing the battery, there might be a different issue. In such instances, the problem could lie within the key fob itself or your vehicle’s electronic system. If you suspect a more complex issue, it’s best to contact our dealership to schedule an appointment with our service department. Our certified technicians can diagnose the problem and provide the necessary repairs, whether it’s related to your key fob or your GMC vehicle.
