What You’ll Need to Replace Your Mercedes Key Fob Battery

Steps to Replace Your Mercedes Key Fob Battery
Ready to tackle this simple DIY project? Follow these step-by-step instructions:
- Locate the release button on the back of your key fob. This small button is usually located near the bottom or side.
- Press the release button and gently slide the emergency key blade out. The key fob casing will separate slightly.
- Use the flat-head screwdriver to carefully pry open the key fob casing. There is usually a small notch where you can insert the screwdriver.
- Identify the old battery. It will be a small, round, silver battery labeled CR2032.
- Gently remove the old battery and install the new battery, making sure the positive (+) side is facing up. Avoid touching the battery’s flat surfaces to ensure optimal performance.
- Align the key fob casing halves and press them firmly together until you hear a click. This indicates the casing is securely closed.
- Reinsert the emergency key blade into its slot.
- Test your key fob by pressing its buttons. If the buttons function correctly, you’ve successfully replaced the battery!
Troubleshooting: What if My Key Fob Still Doesn’t Work?
If you’ve followed the steps above and your key fob still isn’t responding, there are a few possible reasons:
- The new battery is dead. It’s rare, but even new batteries can be faulty. Try installing a different CR2032 battery.
- The battery wasn’t installed correctly. Double-check that the battery is properly seated in the casing with the positive (+) side facing up.
- There’s a different issue with your key fob. In some cases, the problem may not be the battery. You might need to have your key fob diagnosed and repaired by a qualified Mercedes technician.
“One time, a customer came in convinced their Mercedes key fob was completely dead,” says master automotive technician, John Smith. “Turned out, they just had the battery in backward! It’s a simple mistake anyone can make.”
