Buick Lucerne Key Fob Battery Replacement (2006 – 2011)

Introduction

Replacing the battery in your Buick Lucerne key fob is a simple task. You don’t need any special tools, just a flathead screwdriver and a CR2032 coin battery. In this guide, I will walk you through the steps to replace your key fob battery at home.

Tools and Materials

Before you begin, gather the necessary tools and materials:

• Flathead screwdriver
• CR2032 coin battery

You can find the CR2032 battery online for just a few dollars. I have included a link in the description where you can purchase one from Amazon.

Step-by-Step Guide

Step 1: Locate the Seam

First, look at the bottom of your key fob where the key ring attaches. You will see a seam in the plastic with a small slot.

Step 2: Insert the Screwdriver

Take your flathead screwdriver and gently push it into the slot. Be careful not to use too much force, as you could damage the plastic. Twist the screwdriver gently until the key fob starts to open.

Step 3: Open the Key Fob

Once you have created a small gap, you can either pull the key fob apart with your fingers or continue twisting the screwdriver until it is loose enough to open completely.

Step 4: Remove the Circuit Board

Inside the key fob, you will see the battery. In some cases, a small wall may prevent you from sliding the battery out directly. If this is the case, gently remove the circuit board to access the battery.

Step 5: Replace the Battery

Slide out the old battery and dispose of it properly. Take your new CR2032 battery and ensure the positive side, marked with a plus sign, is facing up. Slide the new battery into place.

Step 6: Reassemble the Key Fob

Place the circuit board back into the front side of the key fob, ensuring the battery is facing up. Click the two halves of the key fob back together until they are securely fastened.

Conclusion

That’s it! You have successfully replaced the battery in your Buick Lucerne key fob. This straightforward process can save you time and money compared to visiting a dealership.
