Changing the battery in your 2021 GMC key fob is a quick and easy process that can be done at home with just a few simple tools. This guide will walk you through the steps involved in replacing the battery in your GMC key fob, saving you a trip to the dealership and keeping your key working smoothly.
Understanding Your GMC Key Fob
Before diving into the battery replacement, it’s important to understand the different types of key fobs used in 2021 GMC models. Some models use a traditional flip key, while others utilize a keyless entry remote. Identifying your key fob type will ensure you follow the correct procedure. This is crucial because forcing the wrong method can damage the fob.
Gathering the Necessary Tools
You’ll need only a few tools for this task: a small flathead screwdriver or a similar tool for prying, a fresh CR2032 battery (this is the most common type, but double-check your owner’s manual), and optionally, a small container to hold the screws if your fob uses them. Having everything ready beforehand will make the process even quicker.
Step-by-Step Guide to Changing the Battery in Your 2021 GMC Key Fob
-
Locate the release button: On the side of your key fob, look for a small release button or switch. This button is often located near the key ring. Press the release button and gently slide the metal key out of the fob.
-
Open the key fob: Use your flathead screwdriver or similar tool to carefully pry open the key fob casing. Start at the seam where the two halves of the fob meet. Gently insert the screwdriver and twist slightly to separate the halves. Be careful not to apply too much pressure, as this can damage the plastic.
-
Remove the old battery: Once the fob is open, you should see the old CR2032 battery. Gently pry the old battery out of its compartment using your screwdriver or fingernail. Avoid puncturing the battery as this can cause it to leak.
-
Install the new battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side is facing up. Press down gently until the battery is securely in place.
-
Reassemble the key fob: Carefully align the two halves of the key fob and snap them back together. You should hear a click when the fob is properly closed.
-
Reinsert the metal key: Slide the metal key back into the key fob until it clicks into place.
-
Test the key fob: Try locking and unlocking your vehicle using the key fob to ensure the new battery is working correctly.

Troubleshooting Common Issues
If your key fob still isn’t working after replacing the battery, try these troubleshooting steps:

- Clean the battery contacts: Use a cotton swab and rubbing alcohol to clean the battery contacts inside the key fob. This can help improve the connection.
- Reprogram the key fob: In some cases, you may need to reprogram your key fob to your vehicle after replacing the battery. Refer to your owner’s manual for instructions on how to do this. Often, this involves a specific sequence of turning the ignition key and pressing buttons on the fob.
Tips for Extending Key Fob Battery Life
- Avoid extreme temperatures: Extreme heat or cold can shorten the lifespan of your key fob battery.
- Keep your key fob away from metal objects: Metal objects can interfere with the key fob’s signal and drain the battery faster.
