How to Change Key Fob Battery GMC Sierra: Easy DIY Guide

Losing the ability to unlock your GMC Sierra can be frustrating, especially when you’re in a hurry. A dead key fob battery is a common culprit, but changing it is a simple task that can save you time and stress. This guide will walk you through the process step-by-step, so you can get back on the road in no time.

Why Your Key Fob Battery Might Be Dying

Before diving into the replacement process, it’s helpful to understand why your key fob battery might be losing its charge.

• Battery Age: Like all batteries, key fob batteries have a limited lifespan. Over time, they naturally lose their ability to hold a charge.
• Frequent Use: If you use your key fob often, whether to unlock your doors, start the engine, or open the tailgate, it will drain the battery faster.
• Extreme Temperatures: Exposure to extreme heat or cold can affect battery performance and shorten its lifespan.
• Malfunctioning Electronic Components: In rare cases, a malfunctioning component within the key fob itself might lead to excessive battery drain.

Gather Your Supplies: What You’ll Need

Before you start, make sure you have the following items:

• New CR2032 Battery: This is the most common type of battery used in GMC Sierra key fobs. You can find them at most auto parts stores, convenience stores, and online retailers.
• Small Screwdriver: A small, flathead screwdriver will be needed to open the key fob housing.
• Optional: Tweezers (If you find it difficult to handle the battery with your fingers).

Step-by-Step Guide to Changing Your Key Fob Battery

Now, let’s get down to the actual process of changing the battery:

1. Locate the Key Fob Battery Cover: Your GMC Sierra key fob will have a small, usually concealed, cover that hides the battery. Look for a seam or a small button on the side or back of the fob.
2. Open the Battery Cover: Using your small screwdriver, gently pry open the battery cover. You might need to apply a little pressure, but avoid using excessive force to prevent damage to the fob.
3. Remove the Old Battery: Once the cover is open, you’ll see the old battery inside. Carefully remove it by pulling it out with your fingers or tweezers.
4. Insert the New Battery: Take your new CR2032 battery and align it with the positive (+) and negative (-) terminals inside the key fob. The battery should sit snugly in its compartment.
5. Replace the Battery Cover: Close the battery cover securely. Make sure it clicks into place to ensure proper contact.
6. Test the Key Fob: Press the unlock, lock, or panic button on your key fob to test if the battery is working properly.

Troubleshooting Tips

If your key fob still doesn’t work after replacing the battery, there are a few things you can try:

• Check the Battery Orientation: Ensure the new battery is correctly aligned with the positive and negative terminals.
• Clean the Battery Contacts: Use a clean, dry cloth to wipe the battery contacts and the corresponding contacts inside the key fob.
• Reset the Key Fob: Some GMC Sierra key fobs have a reset button. Refer to your owner’s manual for instructions on how to reset your fob.
• Consult a Mechanic: If you’ve tried all of the above troubleshooting steps and your key fob still isn’t working, it’s best to consult a qualified mechanic to diagnose the issue.
