Introduction

Replacing the battery in your Buick Century key fob is a quick and easy process. This guide will walk you through the steps needed to replace the internal battery, ensuring your key fob works efficiently. You won’t need any special tools, just a CR2032 battery and a flathead screwdriver or coin.

Gather Your Materials

Before starting, make sure you have the necessary materials. You will need a CR2032 coin battery, which is readily available online or in stores. Additionally, have a flathead screwdriver or a coin on hand to open the key fob casing.

• CR2032 coin battery
• Flathead screwdriver
• Coin (optional)

Locate the Indentation

First, examine the bottom of your key fob where the key ring attaches. You’ll notice a small indentation along the seam of the plastic casing. This is where you’ll insert your tool to open the key fob.

Open the Key Fob

Insert your flathead screwdriver or coin into the indentation. Twist the tool to pry open the casing. This may require some force, and you might slightly damage the area. Using a coin can help minimize damage due to its wider surface area.

Remove the Old Battery

Once the key fob is open, you will see the old battery. Use your fingernail or a flathead screwdriver to gently lift and remove the old battery. Be careful not to damage any internal components.

Insert the New Battery

Take your new CR2032 battery and ensure the positive side is facing down. Insert the battery by pushing it towards the metal component first, then click it into place. This ensures the battery is secure and properly positioned.

Reassemble the Key Fob

After inserting the new battery, align the two halves of the key fob casing. Press them together until they click into place. Your key fob is now ready to use.

Testing the Key Fob

Test your key fob to ensure it’s working correctly. If it doesn’t work, double-check the battery’s orientation and ensure it is securely in place. If issues persist, consider consulting a professional.
