Is your 2019 GMC Terrain key fob suddenly not working? Before you panic or schedule an expensive service appointment, the solution might be simpler than you think: a dead battery. Like most modern key fobs, the GMC Terrain key fob relies on a small battery to send signals to your vehicle. Fortunately, replacing this battery is a straightforward process you can easily do yourself with just a few common tools. This guide will walk you through each step to get your key fob working again in no time.
Identifying a Dead Key Fob Battery
The most common sign of a dying key fob battery is an intermittent or complete failure to lock, unlock, or start your 2019 GMC Terrain remotely. You might find you need to press the buttons multiple times, or that the range of your key fob has significantly decreased. In some cases, the key fob might stop working altogether. Before assuming a more complex issue, battery replacement is the quickest and easiest troubleshooting step.
Tools You’ll Need for the Replacement
You won’t need a garage full of tools for this simple task. To replace the battery in your 2019 GMC Terrain key fob, you’ll only require:
- A flathead screwdriver: A small size, like those used for eyeglasses repair, is ideal. This will help you gently pry open the key fob casing.
- A new CR2032 battery: This is the standard 3-volt coin battery used in most GMC key fobs. You can purchase these at most drugstores, supermarkets, hardware stores, and online retailers. Consider buying a multipack to have spares on hand for the future.
Step-by-Step Guide to Replacing Your GMC Terrain Key Fob Battery
Replacing the battery is a quick and easy process. Follow these steps to get your key fob back in working order:
Accessing the Battery Compartment
-
Locate the notch: Turn your GMC Terrain key fob over and look for a small notch or seam. This is usually located on the side or bottom edge of the fob.
-
Insert the screwdriver: Gently insert the tip of your flathead screwdriver into the notch.
-
Pry open the casing: Carefully twist the screwdriver to gently pry the key fob casing open. Avoid using excessive force, as you could damage the plastic. The casing should pop apart relatively easily.
Removing the Old Battery
-
Identify battery orientation: Once the key fob is open, take a close look at the battery and note how it’s positioned. Usually, the positive (+) side faces upwards. This is important for correct installation of the new battery.
-
Remove the old battery: You can often gently pry the old battery out with your fingertip or the edge of the flathead screwdriver. Be careful not to damage the battery contacts inside the key fob.
Inserting the New Battery
-
Install the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is facing in the same direction as the old battery was (usually upwards). It should snap easily into place.
-
Double-check polarity: Confirm that the new battery is correctly seated and the polarity is correct.
Reassembling the Key Fob
-
Align the casing: Carefully align the two halves of the key fob casing back together.
-
Snap the case closed: Press firmly around the edges of the key fob until the two halves snap securely back together. You should hear a click, indicating it’s properly closed.
Testing Your Key Fob After Battery Replacement
Once you’ve reassembled your key fob, test it immediately. Try locking and unlocking your 2019 GMC Terrain remotely, as well as using the remote start function if your vehicle is equipped with it. In most cases, replacing the battery will restore full functionality to your key fob.
When to Seek Professional Help
If you’ve replaced the battery and your 2019 GMC Terrain key fob still isn’t working, there might be a more complex issue. This could involve a problem with the key fob itself or your vehicle’s receiver system. In such cases, it’s best to contact our dealership to schedule a service appointment. Our certified technicians can diagnose the problem and provide the necessary repairs to get you back on the road with a fully functional key fob.
