Is your GMC Yukon key fob suddenly not working? Don’t panic! The most likely culprit is a dead battery. Fortunately, replacing the battery in your GMC Yukon key fob is a straightforward task you can easily handle yourself. This guide will walk you through the simple steps to get your key fob working again, saving you time and a trip to the dealership for a minor issue.
The majority of GMC Yukon key fobs are powered by a common and readily available 3-volt CR2032 battery. These batteries are designed to last for several years, typically three to four, but factors like usage frequency and environmental conditions can affect their lifespan. When the battery begins to weaken, you might notice your key fob becoming less responsive or having a shorter range. Eventually, it will stop working altogether.
Replacing the CR2032 battery is a quick fix that requires minimal tools and no specialized automotive knowledge. Here’s what you’ll need and how to do it:
Tools You’ll Need:
- A new CR2032 battery
- A small flathead screwdriver
Step-by-Step Battery Replacement Guide:
-
Prepare Your Workspace: Find a clean, well-lit area to work on your key fob. This will help you keep track of the small parts.
-
Locate the Opening Slot: Examine your GMC Yukon key fob. You should find a small slot or seam, usually on the side or bottom of the fob. This is where you’ll insert the flathead screwdriver to open the case.
-
Carefully Pry Open the Key Fob: Insert the tip of your flathead screwdriver into the slot. Gently twist or pry to separate the two halves of the key fob case. Avoid using excessive force, as you could damage the plastic casing. The case should pop open relatively easily.

-
Identify Battery Orientation: Once the key fob is open, you’ll see the battery. Before removing the old battery, take a moment to note its orientation – specifically, which side is facing up (positive or negative). Most often, the positive (+) side is facing upwards, towards the back cover of the key fob. This is important for installing the new battery correctly.
-
Remove the Old Battery: Gently pry out the old CR2032 battery. You might be able to use your fingernail or the tip of the screwdriver to carefully lift it out.
-
Insert the New Battery: Take your new CR2032 battery and insert it into the battery compartment, matching the orientation you noted earlier. Ensure it sits snugly in place.

Reassemble the Key Fob: Carefully align the two halves of the key fob case and snap them back together. Press firmly until you hear or feel them click securely into place.
-
Test Your Key Fob: Try using your key fob to lock and unlock your GMC Yukon, start the engine remotely, and test all other functions. In most cases, replacing the battery will restore full functionality.
Troubleshooting and When to Seek Help:
If you’ve replaced the battery and your GMC Yukon key fob still isn’t working, there could be another issue. Here are a few things to consider:
- Battery Compatibility: Double-check that you’ve used a CR2032 battery. Using the wrong type of battery might prevent the key fob from working.
- Battery Installation: Ensure the battery is installed with the correct polarity (+ and – sides).
- Key Fob Damage: Inspect the key fob for any signs of physical damage, such as cracks or broken components, which could affect its functionality.
