Is your 2021 GMC Acadia key fob not working like it used to? The most likely culprit is a dead battery. Fortunately, replacing the battery in your GMC Acadia key fob is a simple task you can do yourself with just a couple of common tools. Most GMC key fobs, including those for the 2021 Acadia, use a 3-volt CR2032 battery, which typically lasts for 3 to 4 years. When it’s time for a change, you won’t need to visit a dealership. This guide will walk you through the easy steps to replace your 2021 GMC Acadia key fob battery and get you back on the road quickly.
To change the battery in your 2021 GMC Acadia key fob, you will only need two things:
- A small flathead screwdriver
- One new CR2032 battery
CR2032 batteries are widely available and can be purchased at most drug stores, supermarkets, hardware stores, and online retailers. Consider buying a multi-pack to have spares on hand for future battery replacements.
Here’s how to replace the battery in your 2021 GMC Acadia key fob:
-
Open the Key Fob: Locate the small slot on the back of your GMC Acadia key fob. Carefully insert the flathead screwdriver into this slot. Gently twist the screwdriver to pry the back panel of the key fob open. Avoid using excessive force to prevent damage to the casing. The key fob should pop open easily.
-
Remove the Old Battery: Once the key fob is open, you will see the CR2032 battery. Take note of the battery orientation – specifically, which side is facing up (positive or negative). This is important for installing the new battery correctly. Typically, the positive (+) side faces upwards or towards the back cover of the key fob. Carefully remove the old battery. You may be able to use the tip of the flathead screwdriver to gently pry it out if needed.
-
Insert the New Battery: Take your new CR2032 battery and insert it into the battery compartment, ensuring that the polarity matches the orientation you noted when removing the old battery. In most cases, the positive (+) side of the new battery should face the same direction as the positive side of the old battery did.
-
Close the Key Fob: Align the two halves of the GMC Acadia key fob casing and gently snap them back together. Press firmly until the case is securely closed and you hear a click.
After replacing the battery, your 2021 GMC Acadia key fob should be working perfectly again.
