Hummer H2 Key Fob Battery Replacement Guide (2008 – 2009)

Introduction

Replacing the battery in your Hummer H2 key fob is a simple and quick task. In this guide, I will walk you through the process step by step. Whether you have the three-button or four-button version, the procedure remains the same. Let’s get started and have your key fob working again in no time.

Tools and Materials Needed

Before we dive into the replacement process, make sure you have the following tools and materials ready:

• Flathead screwdriver
• CR2032 coin battery

If you don’t have a CR2032 battery, you can easily purchase one from Amazon using the link provided in the description.

Step 1: Locate the Indentation

First, take a look at the bottom of your key fob. To the right of where the key ring attaches, you will see a small indentation in the plastic. This is where you will insert your flathead screwdriver.

Step 2: Insert and Twist the Screwdriver

Insert the flathead screwdriver into the indentation and wiggle it until it is securely in place. Once the screwdriver is in place, twist it gently to start opening the key fob. You will notice the fob beginning to separate.

Step 3: Open the Key Fob

After twisting the screwdriver, you can pull the key fob apart with your fingers. This will give you access to the battery and the internal board of the key fob.

Step 4: Remove the Old Battery

To remove the old battery, lift up on the battery and pull out the entire board. This will make it easier to slide the battery out of its compartment.

Step 5: Insert the New Battery

Take your new CR2032 battery and ensure that the positive side (marked with a plus sign) is facing up. Slide the new battery into the metal component, pushing it all the way in.

Step 6: Reassemble the Key Fob

Now that the new battery is in place, it’s time to put everything back together. Place the board with the battery into the front part of the key fob, ensuring the battery is facing up. Then, align the back section of plastic and squeeze the fob back together.

Conclusion

And that’s it! Your Hummer H2 key fob should now be working with a fresh battery. This process is quick and straightforward, taking less than five minutes to complete.
