At Battery Zone, we understand the importance of a working key fob and are here to help. In this guide, you’ll learn how do I change the battery in a Mercedes key fob easily at home or with professional help. Plus, if you need extra car support, such as car battery replacement in Dubai, car jumpstart service, or roadside assistance, we’ll show you local trusted options to keep your driving stress-free.
Why Change Your Mercedes Key Fob Battery?
The key fob controls your Mercedes remotely through radio signals. If the battery runs low, you may notice:
- Reduced range when locking/unlocking
- Delays in response
- Failure to start the car remotely
- Warning lights on your dashboard
Changing the battery is a quick fix that restores normal function without costly repairs.
What Battery Does a Mercedes Key Fob Use?
Most Mercedes key fobs use a small coin cell battery — either a CR2025 or CR2032 lithium battery. These are inexpensive and widely available, including at stores like Battery Zone. Make sure to check your key fob model or the old battery to get the correct type.
Step-by-Step: How to Change Battery in Mercedes Key Fob
Step 1: Get the Right Tools and Battery
You will need a new CR2025 or CR2032 battery and a small flathead screwdriver or coin.
Step 2: Remove the Mechanical Key
Push the release button on your key fob to slide out the mechanical key. This makes it easier to open the fob case.
Step 3: Open the Key Fob
Use a flathead screwdriver or a coin to gently pry open the fob case at the seam. Be careful not to damage the plastic.
Step 4: Remove the Old Battery
Take note of the battery’s position (positive side up or down). Carefully remove the old coin cell battery.
Step 5: Insert the New Battery
Place the new battery in the same position as the old one. Make sure it fits securely.
Step 6: Close the Key Fob
Snap the two halves of the key fob back together until you hear a click.
Step 7: Replace the Mechanical Key
Slide the mechanical key back into place.
Step 8: Test Your Key Fob
Try locking and unlocking your Mercedes to confirm the battery change was successful.
Helpful Tips for Key Fob Battery Replacement
- Avoid touching the new battery with bare hands; oils can reduce battery life.
- Handle the small parts carefully to avoid losing them.
- Dispose of old batteries safely at dedicated recycling points near you.
- If your key fob still doesn’t work, visit a professional or Mercedes service center.
