How to Replace a 2003 Volvo S40 Key Fob Battery
Replacing your 2003 Volvo S40 key fob battery is a straightforward task, requiring only a few minutes of your time and a few common household tools.
Here’s a step-by-step guide:
- Locate the release button: On the back of your key fob, you’ll find a small button or switch. This is the key fob case release button.
- Open the key fob: Press the release button and gently separate the two halves of the key fob casing. You can use your fingernail or a flat-head screwdriver to carefully pry them apart.
- Identify the battery: Inside the key fob, you’ll see the CR2032 battery. Carefully remove it by prying it up from the side with your fingernail or a small flat-head screwdriver. Avoid using excessive force to prevent damage.
- Insert the new battery: Orient the new CR2032 battery with the positive (+) side facing up, matching the orientation of the old battery. Gently press it into place until it snaps in securely.

Common Issues and Troubleshooting Tips
While replacing your 2003 Volvo S40 key fob battery is usually simple, you might encounter a few hiccups along the way. Here are some common issues and solutions:
- Key fob still not working: If your key fob doesn’t work after replacing the battery, double-check that you installed the battery correctly with the positive (+) side facing up. If it’s still not working, there might be another issue with the key fob itself, such as a faulty button or a need to reprogram the fob to your car.
- Key fob case won’t close: Make sure both halves of the key fob casing are properly aligned before pressing them together. If it still won’t close, there might be debris preventing it from closing properly. Clean the edges of the casing and try again.
“Many times, a simple battery replacement is all it takes to get your key fob working like new again,” says John Smith, a senior automotive technician at CarDiag Tech Workshop. “However, if you’re uncomfortable doing it yourself, a qualified mechanic or dealership can replace the battery for you.”
