Is your 2010 Gmc Terrain Key Fob suddenly not working? Don’t worry, you’re not alone! One of the most common culprits for a dead key fob is simply a dead battery. The good news is that replacing the battery in your 2010 GMC Terrain key fob is a straightforward process you can easily do yourself, saving you time and money.
What Battery Does a 2010 GMC Terrain Key Fob Need?
For your 2010 GMC Terrain, you’ll typically need a CR2032 battery for your key fob. This type of battery is widely available online and at most stores that sell batteries. They are also quite inexpensive, usually costing less than $6. You can quickly find replacements online by searching for “CR2032 battery”.
Step-by-Step Guide to Battery Replacement
Replacing the battery in your GMC Terrain key fob is a simple DIY task. Here’s how to do it:
Tools You’ll Need
- A new CR2032 battery
- A small flathead screwdriver or your GMC Terrain’s hidden key (depending on your key fob type)
Opening the Key Fob
The method to open your 2010 GMC Terrain key fob depends on whether you have an older or newer style fob.
-
For newer GMC Terrain key fobs: Look for a small, designated slot on your key fob. Insert the hidden key (usually located within the fob itself – check your owner’s manual if unsure) into this slot. This should allow you to pry the case open.
-
For older GMC Terrain key fobs: If you don’t see a designated slot, locate a small notch on the side of the key fob casing. Carefully insert a thin object, like a flathead screwdriver, into this notch. Gently twist or pry to separate the two halves of the key fob case. Be careful not to apply too much force to avoid damaging the plastic.
Replacing the Battery
Once you have the key fob case open:
- Gently access the circuit board: Carefully lift the circuit board inside the key fob to reveal the battery compartment.
- Note the battery orientation: Before removing the old battery, take a quick look at how it’s positioned in the case. Pay attention to which side is facing up (+) and down (-). This will ensure you insert the new battery correctly.
- Remove the old battery: Take out the dead CR2032 battery.
- Insert the new battery: Place the new CR2032 battery into the compartment, making sure it’s oriented the same way as the old one.
- Close the case: Carefully snap the two halves of the key fob case back together until they are securely closed.
Testing Your Key Fob
After replacing the battery and closing the case, test your GMC Terrain key fob to ensure it’s working correctly. Press the buttons to lock, unlock, or start your vehicle (if applicable). If everything works, you’re all set!
Troubleshooting: What if the New Battery Doesn’t Work?
If your key fob still isn’t working after replacing the battery, here are a few things to check:
- Battery Connections: Double-check that the battery is properly seated in the compartment and that the metal contacts are clean and making good contact with the battery. Sometimes, a little bit of dirt or corrosion can interfere with the connection.
- Battery Orientation: Make sure you inserted the new battery with the correct polarity (+ and – sides).
- Key Fob Damage: If your key fob has been damaged or exposed to moisture, internal components might be faulty, and a battery replacement won’t fix the issue.
If you’ve tried these troubleshooting steps and your 2010 GMC Terrain key fob still isn’t functioning, you may need to consider replacing the entire key fob.
