In this guide, we’ll detail how to change the battery in your GMC key fob and get it working smoothly again.

Whether you own a GMC Sierra, Yukon, or another model, a GMC remote battery change is generally a quick and straightforward process. By following the steps outlined in this guide, you can save time and avoid costly fees. Regular maintenance, such as replacing the battery every three to four years, ensures your key fob remains in good working condition.

Identifying Your GMC Key Fob Model

Before you start, identify your specific GMC key fob model. This ensures you purchase the correct battery and follow the right directions when replacing it.

Why Knowing Your Key Fob Model Is Important

Different GMC models may have slightly different key fobs. For example, if your GMC Yukon key fob isn’t working properly, you’ll need to replace it. However, the procedure for replacing a GMC Sierra key fob may differ from replacing a key fob battery for a GMC Yukon. Knowing your model will make GMC fob battery replacement smoother.

Common GMC Key Fob Models

Common key fobs include:

• GMC Sierra key fob: A standard fob with lock/unlock, remote start, and a panic button
• GMC Yukon key fob: Includes advanced features such as keyless entry and hands-free trunk opening
• GMC Terrain key fob: Compact with basic features but designed for keyless start

Finding Your Key Fob Model Number

If you need to replace a GMC key fob battery, you can locate the model number on the back of the key fob or in your vehicle’s user manual.

Step-By-Step Guide: Changing the Battery in Your GMC Key Fob

Now that you know your key fob model, here’s how to replace the battery.

Gather Necessary Tools and Materials

Before you replace the battery in your GMC key fob, make sure you have the tools for a smooth battery replacement. You’ll need:

• A small flathead screwdriver or a coin (to open the key fob)
• A new CR2032 3V battery (the most commonly used battery for GMC key fobs)
• A clean cloth to prevent scratches on your key fob

Make sure the new GMC key fob battery is the right type for your specific model, and always check the user manual for confirmation.

Opening Your GMC Key Fob

Start by locating the small seam or notch around the key fob’s edge. Most GMC key fobs have a visible seam where the two halves meet. This is where you’ll insert a flathead screwdriver or coin to pop open the key fob. When you’ve found the seam, gently insert the screwdriver into the notch, then twist it to pry the fob open. Be careful not to use too much force, as you could damage the casing.

Removing the Old Battery

With the key fob open, you’ll see the battery resting in its compartment. This is typically a CR2032 button battery. Using the screwdriver or your fingernail, carefully lift the old battery out of the compartment. Take note of the battery’s orientation so you can install the new one correctly. Usually, the positive side faces upward.

Installing the New Battery

Insert the new CR2032 battery into the compartment. Make sure that the positive side is facing up, just like the old one. Press down gently until the new battery is securely in place.

Reassembling Your Key Fob

To reassemble your key fob, align the two halves of the fob. Press the halves together firmly until you hear a snap. Make sure that they click securely and that there are no gaps between the two halves.

Testing Your GMC Key Fob

After reassembling the key fob, it’s time to test it. Stand near your vehicle and press any button on the key fob to ensure it’s working. If the vehicle responds by locking, unlocking, or starting remotely, congratulations — your GMC key fob battery replacement was successful.

Troubleshooting: When Your Key Fob Still Isn’t Working

Sometimes, your key fob may not work even after replacing the battery. Here are a few potential reasons and solutions you can try before bringing it into our dealership:

• Incorrect installation has affected the battery: Double-check the battery orientation. The positive side should always face up.
• The key fob needs reprogramming: If your key fob isn’t responding after a battery change, it may need reprogramming. Refer to your vehicle’s user manual for specific steps, or contact a local GMC dealer such as Steve Austin’s Auto.
• The key fob has internal damage: If you dropped the key fob or exposed it to water, the internal components may have sustained damage. In this case, you may need to replace the key fob.
• A GMC Yukon or GMC Sierra key fob isn’t working: Both the GMC Yukon and Sierra key fobs may require additional troubleshooting if they’re still unresponsive. Sometimes, resetting the vehicle’s electronic system by disconnecting the 12V battery can help.
