How to Replace the Battery in a Volvo S40 Key Fob (1999 – 2003)

Introduction

If you drive a Volvo S40 from 1999 to 2003, you may find yourself needing to replace the battery in your key fob. This is a simple process that only takes a few minutes and requires minimal tools. In this guide, I will walk you through the steps to replace your key fob battery efficiently.

Tools and Materials Needed

Before you begin, make sure you have all the necessary tools and materials. Here’s what you’ll need:

• CR2032 battery
• Torx head screwdriver (size T8)

You can purchase a CR2032 battery online. Additionally, if you don’t already have a Torx head screwdriver, you can find an affordable set online as well.

Step-by-Step Instructions

Replacing the battery in your Volvo S40 key fob is straightforward. Follow these steps to get the job done:

1. Remove the Screw

Locate the screw on the back of the key fob. It looks like a star and requires a Torx head screwdriver. Use a Torx head size T8 to unscrew it. This is the only challenging part, as you need the correct screwdriver.

2. Open the Key Fob

Once the screw is removed, start to open the key fob. Be careful not to snap it open abruptly. There are tabs at the top that can break if you’re not gentle. Instead, open it slightly and then push upwards to release the tabs without breaking them.

3. Remove the Old Battery

With the key fob open, you will see the battery. Use your fingernail or a flathead screwdriver to gently lift the battery from the side. Be careful not to damage any components inside the key fob.

4. Insert the New Battery

Take your new CR2032 battery and ensure the positive side (marked with a plus sign) is facing down. Snap it into place gently. Make sure it fits snugly in the battery compartment.

5. Reassemble the Key Fob

Slide the top part of the key fob back onto the tabs. Once the tabs are aligned, squeeze everything back together. Finally, replace the screw and tighten it with your Torx head screwdriver.

Additional Tips

Here are a few extra tips to ensure a smooth battery replacement process:

• Work on a clean, flat surface to avoid losing small parts.
• Take your time to avoid breaking any tabs or damaging the key fob.
• Dispose of the old battery properly, as it contains harmful chemicals.
