Is your 2010 GMC Terrain key fob not working? Before you panic, the most common culprit is often a dead battery. Replacing your GMC Terrain key fob battery is a simple and cost-effective fix you can do yourself. This guide will walk you through the process of replacing the battery in your 2010 GMC Terrain key fob, getting you back on the road quickly.
GMC Terrain key fobs typically use a CR2032 battery, a widely available and inexpensive option. You can find CR2032 batteries online or at most stores that sell batteries. The cost is usually less than $6, making this a much cheaper solution than replacing the entire key fob.
Steps to Replace Your 2010 GMC Terrain Key Fob Battery:
The method to open your GMC Terrain key fob varies slightly depending on the model year. Here’s how to open both newer and older style fobs:
For Newer GMC Terrain Key Fobs:
- Locate the hidden key. Most newer models have a physical key inserted into the bottom of the key fob.
- Remove the hidden key. There’s usually a small button or release to slide and remove the key.
- Insert the key into the designated slot. Once the key is removed, you’ll see a slot where the key was. Insert the key into this slot.
- Pry open the case. Gently twist or pry the key in the slot to separate the two halves of the key fob case.
For Older GMC Terrain Key Fobs:
- Locate the notch. Examine the edges of your key fob for a small notch or seam.
- Use a thin object to pry. Insert a thin, flat object like a small flathead screwdriver or a plastic pry tool into the notch.
- Pry open the case. Carefully twist or pry to separate the two halves of the key fob case. Be gentle to avoid damaging the plastic.
Once the Key Fob is Open:
- Access the battery. After opening the case, carefully lift the circuit board to reveal the battery compartment.
- Note battery orientation. Before removing the old battery, take note of which way it is facing (+ side up or down). This is important for correct installation of the new battery.
- Remove the old battery. Gently pry out the old CR2032 battery.
- Insert the new battery. Place the new CR2032 battery into the compartment, ensuring it’s in the same orientation 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:
- Test the functionality. Press the buttons on your key fob to test if it’s working. Try locking and unlocking your car, and if applicable, the remote start.
- Troubleshooting. If the key fob still doesn’t work, double-check the battery orientation and ensure the battery contacts are clean and making good contact with the battery. You can gently clean the contacts with a cotton swab and a bit of rubbing alcohol if needed.
Types of Key Fobs:
Understanding the type of key fob you have can be helpful. Here are common types:
- Standard Remotes: Basic remotes with just buttons, no extra features.
- Flip Keys: Keys attached to the remote that flip out.
- Remote Heads: Keys integrated with the remote, key blade is always visible.
- Fobik Keys: Remotes with a separate, hidden key inside.
- Smart Keys: Often associated with push-to-start ignition systems.
