Is your 2021 GMC Terrain key fob not working? Don’t worry, you’re not alone. One of the most common culprits for a malfunctioning key fob is a dead battery. Fortunately, replacing the battery in your GMC Terrain key fob is a straightforward process you can easily handle yourself. Most GMC key fobs, including those for the 2021 Terrain, use a 3-volt CR2032 battery, known for its longevity, typically lasting three to four years. When the time comes for a replacement, you won’t need to visit a dealership right away. This guide will walk you through how to change your 2021 Gmc Terrain Key Fob Battery quickly and efficiently.
To replace your 2021 GMC Terrain key fob battery, you’ll only need a couple of simple tools. First, you’ll need a small flathead screwdriver. This will be used to gently pry open the key fob casing. Secondly, you’ll need a new CR2032 battery. These batteries are widely available at most drugstores, hardware stores, and even grocery stores. Purchasing a multi-pack of CR2032 batteries might be a good idea to have spares on hand for future replacements.
Now, let’s get to the battery replacement process. Carefully examine your 2021 GMC Terrain key fob. You’ll notice a small seam running along the edge of the fob. This is where you’ll use the flathead screwdriver. Gently insert the tip of the screwdriver into the seam and carefully twist. The key fob cover should pop open. Avoid using excessive force to prevent damaging the casing. Once the case is open, you’ll see the old CR2032 battery. Take note of the battery’s orientation, specifically which side is facing up (positive or negative). This is important for correct installation of the new battery.
With the key fob open, carefully remove the old battery. You can often do this with your fingertip, or use the flathead screwdriver to gently nudge it out if needed. Now, take your new CR2032 battery and install it in the same orientation as the old one. Typically, the positive (+) side of the battery will face upwards, often towards the back cover of the key fob. Ensure the new battery is securely seated in its place.
After installing the new 2021 GMC Terrain key fob 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. Once reassembled, test your key fob to ensure it’s working correctly. In most cases, replacing the battery will solve the issue, and your 2021 GMC Terrain key fob should be functioning like new.
However, if you’ve replaced the battery and your 2021 GMC Terrain key fob is still not working, there might be another issue. It’s possible there’s a problem with the key fob itself or your vehicle’s receiver system. In such cases, it’s best to seek professional assistance. Contact a certified GMC dealership or a qualified automotive technician. They can diagnose the problem and provide the necessary repairs or further assistance to get your 2021 GMC Terrain key fob working again. We at keyfobx.com are experts in key fob issues and recommend seeking professional help if a battery replacement doesn’t solve the problem.
