What You’ll Need to Replace Your Volvo S40 Key Fob Battery
Don’t worry, you won’t need a mechanic’s toolset for this job. Here’s what you’ll need:

- A small flathead screwdriver: This will help you pry open the key fob casing.
- A soft cloth or surface: This will protect your key fob from scratches during the process.
How to Replace the Battery in Your 2004 Volvo S40 Key Fob: Step-by-Step
Now, let’s get down to business. Follow these easy steps to replace your key fob battery:
- Locate the release button: On the back of your Volvo S40 key fob, you’ll see a small, round button. This is the release button.
- Release the valet key: Gently press the release button and slide the valet key out of the fob.
- Separate the fob halves: With the valet key removed, use your fingernail or the flathead screwdriver to carefully pry open the key fob casing along the seam. Be gentle to avoid damaging the casing.
- Replace the battery: Inside, you’ll see the old CR2032 battery. Carefully remove it and replace it with the new battery, making sure to match the positive (+) and negative (-) sides.
- Reassemble the fob: Align the two halves of the key fob casing and press them together firmly until you hear a click.
- Reinsert the valet key: Slide the valet key back into its slot on the fob.
- Test the key fob: Check all the buttons on your key fob to ensure they are working properly.
Pro Tip from John Miller, Automotive Electrician: “If your Volvo S40 key fob still doesn’t work after a battery replacement, there might be a programming issue. Try reprogramming the fob yourself by following the instructions in your owner’s manual, or consult a qualified automotive locksmith or dealer.”
Still Having Trouble?
Sometimes, replacing the battery might not be enough. Here are some common issues and solutions:
- Key fob not responding at all? Double-check that the new battery is properly installed and that the positive and negative terminals are aligned correctly.
- Key fob working intermittently? The battery contacts inside the fob might be dirty or corroded. Try cleaning them with a cotton swab and some rubbing alcohol.
- Key fob working, but car won’t start? This could indicate a more serious issue with your car’s immobilizer system. It’s best to consult a qualified mechanic or dealer for diagnosis and repair.
