Buick LaCrosse Key Fob Battery Replacement Guide (2010 – 2016)

Introduction

Replacing the battery in your Buick LaCrosse key fob can seem daunting, but it’s a straightforward process. This guide will walk you through the steps to ensure your key fob is back in working order. Whether you have a key fob with three, four, or five buttons, the process remains the same.

What You Need

To replace the battery in your Buick LaCrosse key fob, you only need one CR2032 battery. These batteries are readily available online.

Step-by-Step Battery Replacement

1. Flip Out the Internal Key

First, locate the button on your key fob that flips out the internal key. Press this button to release the key. This step is essential as it provides access to the back piece of plastic that needs to be removed.

2. Remove the Back Piece of Plastic

With the internal key flipped out, hold the key fob firmly. You’ll notice a small ridge inside the area where the key was stored. Push up on this ridge to release the back piece of plastic. It doesn’t require much pressure, so be gentle to avoid any damage.

3. Take Out the Old Battery

Once the back piece of plastic is removed, you’ll see the battery. There’s a small piece of plastic covering one side of the battery. Apply some pressure on the exposed side of the battery to pop it out. Dispose of the old battery responsibly.

4. Insert the New CR2032 Battery

Take your new CR2032 battery and ensure the positive side (the side with the text) is facing up. Slide the battery into the compartment, making sure it sits securely.

5. Reassemble the Key Fob

With the new battery in place, align the back piece of plastic with the key fob and press it back into place. Ensure it clicks securely. Finally, flip the internal key back into its original position. Your key fob should now be functioning correctly.

Additional Tips

• Handle the key fob gently to avoid damage.
• Ensure the battery is inserted with the correct polarity.
• Dispose of the old battery properly.
• Consider purchasing a pack of CR2032 batteries for future use.
