Is your GMC key fob not working as reliably as it used to? Or perhaps it has stopped working altogether? Before you assume the worst, the most likely culprit is a dead battery. Fortunately, replacing the GMC key fob battery is a straightforward process that you can easily handle yourself. This guide will walk you through each step, ensuring you can quickly restore your key fob to perfect working order.
What You’ll Need to Replace Your GMC Key Fob Battery
Before you begin, gather these simple tools:
- A new CR2032 battery: This is the standard 3-volt battery used in most GMC key fobs. You can purchase these at most drugstores, hardware stores, and online retailers. Consider buying a multi-pack to have spares on hand.
- A small flathead screwdriver or prying tool: This will be used to gently open the key fob casing.
Step-by-Step Guide to Replacing Your GMC Key Fob Battery
Follow these easy steps to replace your GMC key fob battery:
-
Locate the small notch on your GMC key fob. This notch is usually located on the side or bottom of the key fob casing.
-
Carefully insert the flathead screwdriver into the notch. Gently twist or pry to separate the two halves of the key fob. Avoid using excessive force to prevent damage to the casing.

-
Identify the battery type and orientation. Take note of how the old battery is positioned in the compartment, specifically noting which side is facing up (+ positive or – negative). This will ensure you install the new battery correctly. The CR2032 battery is typically round and flat.
-
Remove the old battery. You may be able to gently pry it out with your fingertip, or use the flathead screwdriver if it’s snug.
-
Insert the new CR2032 battery. Place the new battery into the compartment, ensuring it’s oriented the same way as the old battery (positive side in the correct position, usually facing upwards).

What if Replacing the GMC Key Fob Battery Doesn’t Work?
In the vast majority of cases, replacing the battery will solve the problem and restore your GMC key fob’s functionality. However, if you’ve replaced the battery and your key fob is still not working, there might be another issue.
Possible reasons for a non-working key fob after battery replacement could include:
- Incorrect battery installation: Double-check that the battery is the correct type (CR2032) and is inserted with the correct polarity.
- Key fob damage: If the key fob has been dropped or exposed to moisture, internal damage could be the cause.
- Vehicle electronic issues: In rare cases, the problem might lie with your GMC vehicle’s receiver or immobilizer system.
