Is your GMC Terrain key fob not working as reliably as it used to? Perhaps you need to be closer to your vehicle for it to unlock, or maybe it’s stopped working altogether. The most likely culprit is a dead battery. Fortunately, replacing the battery in your GMC Terrain key fob is a simple task you can do yourself in just a few minutes. This guide will walk you through the process step-by-step, saving you time and a trip to the dealership.
What You’ll Need
Before you begin, gather these simple tools and supplies:
- A new CR2032 battery: This is the standard 3-volt coin cell battery used in most GMC key fobs. You can find these at most drugstores, supermarkets, hardware stores, and online retailers. Consider buying a multi-pack to have spares on hand for future battery replacements.
- A small flathead screwdriver: This will be used to gently pry open the key fob case. If you don’t have a screwdriver, a thin butter knife or even the tip of your car key can work carefully.
Step-by-Step Guide to Replacing Your GMC Terrain Key Fob Battery
Replacing the battery is a straightforward process. Just follow these steps:
-
Locate the Notch to Open the Fob: Turn your GMC Terrain key fob over and look for a small notch or slot. This is usually located on the side or bottom edge of the key fob casing.
-
Carefully Pry Open the Key Fob: Insert the tip of your flathead screwdriver (or alternative tool) into the notch. Gently twist or pry to separate the two halves of the key fob. Avoid using excessive force, as you could damage the plastic casing. The case should pop open with minimal effort.
-
Identify the Battery Type and Orientation: Once the key fob is open, you’ll see the CR2032 battery. Take a quick look at how the old battery is positioned before removing it. Note whether the positive (+) side is facing up or down. Typically, the positive side faces upwards towards the back cover of the fob.
-
Remove the Old Battery: You can usually pry the old battery out with your fingertip or the edge of the screwdriver. Be gentle not to damage the battery compartment clips.
-
Insert the New CR2032 Battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is oriented in the same direction as the old battery you removed. Push down gently until the battery is securely in place.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob case. Press them firmly together until they snap back into place. You should hear a click confirming that the case is securely closed.
Testing Your Key Fob
After reassembling your GMC Terrain key fob, test it to ensure the new battery is working correctly. Try locking and unlocking your doors remotely, and test the remote start feature if your vehicle is equipped with it. In most cases, your key fob should now be functioning perfectly with the new battery.
What if My Key Fob Still Doesn’t Work?
If you’ve replaced the battery and your GMC Terrain key fob still isn’t working, there might be another issue. While a dead battery is the most common cause, other potential problems could include:
- Key fob malfunction: The internal electronics of the key fob itself could be damaged.
- Vehicle electronic issues: There might be a problem with your GMC Terrain’s receiver or other electronic systems.
In these situations, it’s best to consult with a professional. Contact our dealership to schedule an appointment with our service department. Our certified technicians can diagnose the problem and get your key fob working again, ensuring you have reliable access to your GMC Terrain.
