Is your GMC key fob not working? Before you worry about expensive repairs, the most likely culprit is a dead battery. The good news is that replacing the battery in your GMC key fob is a straightforward process you can easily do yourself at home. This guide will walk you through each step, ensuring you get your key fob working again in no time.
GMC key fobs commonly use a 3-volt CR2032 battery, known for its long life, typically lasting three to four years. However, like all batteries, they eventually need replacing. Fortunately, these batteries are readily available and affordable, found in most department stores, hardware stores, and online retailers that sell batteries. You’ll likely only need a common flathead screwdriver and a fresh CR2032 battery to get the job done.
Tools You’ll Need
Before you begin, gather these simple tools:
- A new CR2032 battery: This is the standard replacement battery for most GMC key fobs. Ensure you purchase a fresh battery for optimal performance.
- A small flathead screwdriver: This tool will be used to gently pry open the key fob casing.
Step-by-Step Guide to Battery Replacement
Follow these easy steps to replace your GMC key fob battery:
-
Locate the small notch: Examine your GMC key fob for a small notch or slot. This is usually located on the side or bottom of the fob.
-
Insert and twist the screwdriver: Carefully insert the tip of your flathead screwdriver into the notch. Gently twist the screwdriver to pry the key fob casing open. Avoid using excessive force to prevent damage to the plastic casing.

Open the key fob: Once you’ve gently pried it, the back panel of the key fob should pop open. Carefully separate the two halves of the key fob casing.
-
Remove the old battery: Take note of the battery’s orientation before removing it. Observe whether the positive (+) side is facing up or down. This is important for installing the new battery correctly. Gently remove the old battery. You might be able to use the flathead screwdriver to help nudge the battery out if needed.
-
Insert the new battery: Place the new CR2032 battery into the battery compartment, ensuring the positive (+) side is facing the same direction as the old battery was removed. Correct polarity is crucial for the key fob to function.
