Is your 2020 GMC Terrain key fob not working as reliably as it used to? Before you worry about complicated repairs, the most likely culprit is a dead battery. Fortunately, replacing the battery in your GMC Terrain key fob is a straightforward process you can easily handle yourself. This guide will walk you through each step to get your key fob working like new again.
What Kind of Battery Does a 2020 GMC Terrain Key Fob Need?
The 2020 GMC Terrain key fob, like many modern car keys, uses a common and readily available 3-volt CR2032 battery. This small, round battery is designed for longevity, typically lasting between three to four years under normal use. You can find CR2032 batteries at most drugstores, supermarkets, hardware stores, and online retailers. It’s always a good idea to keep a spare CR2032 battery or two at home, so you’re prepared when your key fob battery eventually needs replacing.
Tools You’ll Need for a GMC Terrain Key Fob Battery Change
You won’t need a toolbox full of equipment for this simple task. In fact, you probably already have the only tool required:
- Flathead Screwdriver: A small, flathead screwdriver will be used to gently pry open the key fob case. If you’re concerned about scratching the plastic, you can wrap the tip of the screwdriver with a thin cloth or tape.
That’s all you need! With a fresh CR2032 battery and a flathead screwdriver, you’re ready to bring your GMC Terrain key fob back to life.
Step-by-Step Guide to Replacing Your 2020 GMC Terrain Key Fob Battery
Let’s get started with the battery replacement. Follow these simple steps:
-
Locate the Notch: Turn your GMC Terrain key fob over and look for a small notch or slot. This is usually located on the back of the key fob casing.
-
Pry Open the Case: Insert the tip of your flathead screwdriver into the notch. Gently twist the screwdriver to pry the two halves of the key fob case apart. Be careful not to apply excessive force, as you could damage the plastic casing. The case should pop open with minimal effort.
-
Identify Battery Orientation: Once the case is open, you’ll see the CR2032 battery. Take a moment to note the orientation of the battery before removing it. Usually, the positive (+) side of the battery faces upwards or towards the back cover of the key fob. This is important to ensure you install the new battery correctly.
-
Remove the Old Battery: Carefully remove the old battery. You may be able to gently pry it out with your fingernail or the flathead screwdriver if needed.
-
Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring that the positive (+) side is facing the same direction as the old battery was.
-
Reassemble the Key Fob: Align the two halves of the key fob case and snap them firmly back together. You should hear a click, indicating that the case is securely closed.

Testing Your Newly Replaced Key Fob Battery
After reassembling your key fob, test it to ensure it’s working correctly. Try locking and unlocking your GMC Terrain remotely, and test the remote start function if your vehicle is equipped with it. In most cases, replacing the battery will solve the issue, and your key fob should be functioning perfectly again.
What if the New Battery Doesn’t Fix the Problem?
If you’ve replaced the battery and your 2020 GMC Terrain key fob is still not working, there might be another issue. While a dead battery is the most common cause, other potential problems could include:
- Key Fob Damage: The key fob itself may be damaged internally due to drops or exposure to moisture.
- Vehicle Electronic Issues: In rare cases, there might be a problem with your GMC Terrain’s receiver or other electronic systems.
If you suspect a more complex issue, it’s best to consult with a professional. Contact your local GMC dealership or a qualified automotive technician.
