Replacing the battery in your GMC Terrain key fob is a straightforward process that you can easily do at home. Whether your key fob has a different button layout or number of buttons, the procedure remains the same for models from 2018 to 2021.

In this guide, I will walk you through the steps to replace the battery quickly and efficiently. By the end of this tutorial, you will have a fully functional key fob with a new battery, saving you time and money.

What You Will Need

Before starting the battery replacement process, gather the following items:

• Flathead screwdriver
• CR2032 battery

If you don’t have a CR2032 battery, you can purchase one online. The link provided in the description will direct you to Amazon, where you can buy the battery for a few dollars.

Step-by-Step Instructions

Step 1: Remove the Internal Key

First, locate the button on the side of your key fob. Press and hold this button while pulling on the key ring. This action will release the internal key from the fob.

Step 2: Open the Key Fob

With the key removed, look inside the keyhole. You will see two small holes and an indentation in the middle. This indentation is where you will insert your flathead screwdriver.

Insert the flathead screwdriver into the indentation and hold the sides of the key fob. Avoid holding the back, as this is the part you will be removing. Twist the screwdriver gently to open the fob. Once it pops open slightly, use your fingers to pull it apart completely.

Step 3: Remove the Old Battery

With the key fob open, you will see the old battery. Use the corner of your flathead screwdriver to pry the battery out carefully. Dispose of the old battery properly.

Step 4: Insert the New Battery

Take your new CR2032 battery and ensure the positive side (marked with a plus sign) is facing down. Click the battery into place with the positive side down.

Step 5: Reassemble the Key Fob

Once the new battery is in place, align the two halves of the key fob and press them together until they click. Give it a good squeeze to ensure it is securely closed.

Finally, reinsert the internal key into the fob. You have now successfully replaced the battery in your GMC Terrain key fob.
