It’s a common frustration: you reach for your GMC Yukon key fob, press a button, and nothing happens. Before you assume the worst, consider the simplest solution – the battery is likely dead. For most GMC Yukon models, the key fob relies on a standard 3-volt CR2032 battery. These batteries are designed to last for several years, typically three to four, but eventually, they will need replacing. The good news is that changing the battery in your GMC Yukon key fob is a straightforward task you can easily handle yourself with just a couple of basic tools. This guide will walk you through the process step-by-step, saving you time and a trip to the dealership for a problem you can resolve at home.
To replace the battery in your GMC Yukon key fob, you will only need a few readily available items:
- A new CR2032 battery: This is the standard battery type for most GMC key fobs. You can purchase these at most drugstores, supermarkets, hardware stores, and online retailers. It’s always a good idea to have a spare CR2032 battery or two on hand for future replacements.
- A small flathead screwdriver: This tool will be used to gently pry open the key fob casing. If you don’t have a screwdriver, a thin but sturdy tool like a butter knife or even a guitar pick can sometimes work, but be extra careful to avoid damaging the plastic.
Once you have gathered your tools and replacement battery, follow these simple steps to change the battery in your GMC Yukon key fob:
-
Locate the small notch on your GMC Yukon key fob: Examine the key fob closely, and you should find a small slot or notch along the seam where the two halves of the casing meet. This notch is specifically designed to provide a point of leverage for opening the fob.
-
Carefully pry open the key fob: Insert the tip of your flathead screwdriver into the notch. Apply gentle but firm pressure to twist the screwdriver. The key fob casing should begin to separate. Work your screwdriver around the seam if necessary, gently prying until the two halves of the key fob casing come apart. Avoid using excessive force, as this could damage the plastic housing of the key fob.

Identify the battery orientation: With the key fob open, you will see the CR2032 battery. Before removing the old battery, take a moment to note the orientation – specifically, which side is facing up (positive or negative). In most GMC Yukon key fobs, the positive (+) side of the battery faces upwards, usually towards the back cover of the fob. This is crucial for ensuring the new battery is installed correctly.
-
Remove the old battery and insert the new one: Gently remove the dead CR2032 battery. You may be able to pry it out with your fingernail or the edge of the screwdriver. Once the old battery is out, insert the new CR2032 battery, making sure to match the orientation you noted in the previous step. Push the new battery firmly into place to ensure good contact.

Reassemble the key fob: Carefully align the two halves of the key fob casing back together. Press them firmly until they snap securely back into place. You should hear a click or feel them latch together, ensuring the fob is properly closed and protected.
After reassembling your GMC Yukon key fob, test it to ensure it is working correctly. In the vast majority of cases, replacing the battery will restore full functionality to your key fob. However, if your key fob still doesn’t work after replacing the battery, there might be a more complex issue. In such instances, it’s recommended to consult with a qualified automotive technician to diagnose and resolve any potential electronic or key fob malfunctions. While battery replacement is a simple DIY fix, more intricate problems may require professional expertise.
