Is your GMC Terrain key fob not working? Before you consider a costly replacement, the most likely culprit is a dead battery. Fortunately, changing the battery in your GMC Terrain key fob is a simple and affordable DIY task. This guide will walk you through the process of replacing your GMC Terrain key fob battery, ensuring you get back on the road quickly. Typically, GMC Terrain key fobs use a CR2032 battery, readily available online and at most stores for under $6.
Step-by-Step Guide to Replacing Your GMC Terrain Key Fob Battery
The method to open your GMC Terrain key fob depends slightly on the model year. Here’s how to open both newer and older versions:
For Newer GMC Terrain Key Fobs:
- Locate the Hidden Key: Find the release button or latch on your key fob. Press and hold it to detach the mechanical key.
- Insert the Key: Once the mechanical key is removed, you’ll see a slot or opening where the key was. Insert the key into this designated slot.
- Pry Open the Case: Gently twist or lever the mechanical key within the slot. This action will pry open the key fob case. You might hear a click as the case begins to separate.
For Older GMC Terrain Key Fobs:
- Find the Notch: Examine the edges of your key fob for a small notch or seam. This is usually located along the side of the fob.
- Use a Thin Tool: Take a thin, flat object like a small flathead screwdriver or a credit card.
- Pry at the Notch: Carefully insert the edge of your tool into the notch. Gently twist or pry to separate the two halves of the key fob case. Avoid using excessive force to prevent damage to the casing.
Battery Replacement Process (For All GMC Terrain Key Fobs):
- Open the Key Fob Case: Follow the appropriate steps above to successfully open your GMC Terrain key fob.
- Access the Circuit Board and Battery: Once open, you’ll see the internal components. Gently lift the circuit board if necessary to reveal the battery underneath. Be careful not to detach any components.
- Note Battery Orientation: Before removing the old battery, take a close look at how it’s positioned in the case. Note the positive (+) and negative (-) sides to ensure you insert the new battery correctly.
- Remove the Old Battery: Carefully remove the depleted CR2032 battery. You might be able to pry it out gently with your fingertip or the same thin tool used to open the case.
- Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring it’s in the same orientation as the old one (positive side up, if that was the original configuration). Push down gently to ensure it’s securely seated.
- Close the Key Fob Case: Carefully align the two halves of the key fob case and press them firmly together until they snap back into place. Ensure the case is completely closed with no gaps.
- Test Key Fob Functionality: Press the buttons on your key fob to test if it’s working correctly. Try locking and unlocking your GMC Terrain remotely.
If your Gmc Terrain Replacement Key Fob is still not working after a battery change, double-check the battery orientation and ensure the battery contacts are clean and making good contact.
