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.
