How to Replace Battery in GMC Door Key Fob

Replacing the battery in your GMC key fob is a quick and easy process that can save you the time and expense of visiting a dealership. This guide will walk you through the steps involved in replacing the battery for various GMC key fob models, helping you get back on the road with a fully functioning key fob.

Locating the Key Fob Battery Compartment

The first step in replacing your GMC key fob battery is locating the battery compartment. Most GMC key fobs have a small release button or slot on the back or side. Some models may require you to separate the key fob halves using a small flathead screwdriver. Consult your owner’s manual for specific instructions for your GMC model year and key fob type.

What Type of Battery Does a GMC Key Fob Use?

GMC key fobs typically use a CR2032 3-volt lithium coin battery. These batteries are readily available at most electronics stores, pharmacies, and online retailers. It’s always a good idea to have a spare CR2032 battery on hand, just in case.

Step-by-Step Guide on How to Replace the Battery

Once you’ve located the battery compartment and have your new CR2032 battery, follow these steps:

1. Open the compartment: Carefully press the release button or insert the flathead screwdriver into the designated slot and gently pry open the compartment.
2. Remove the old battery: Use your fingernail or the flathead screwdriver to carefully lift the old battery out of the compartment. Note the orientation of the positive (+) and negative (-) sides of the battery.
3. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces the same direction as the old battery.
4. Close the compartment: Snap the key fob halves back together or close the battery compartment cover securely.

Testing the Key Fob After Battery Replacement

After replacing the battery, test all the key fob functions, including locking and unlocking the doors, remote start (if equipped), and the panic button. If any of the functions aren’t working, double-check the battery installation and ensure the compartment is closed tightly. In some cases, you may need to reprogram your key fob.
