Consistent use of remote functions will eventually wear out the battery in your key fob, which means the time to replace it will come.

To help Mercedes-Benz owners from Barrington and beyond troubleshoot their key fob battery issues, the experts at our Mercedes-Benz parts center took the time to answer some common questions.

When Should I Replace My Mercedes-Benz Key Fob Battery?

If you notice your Mercedes-Benz key fob or push-button start functions do not work properly, chances are you need to replace your battery. Signs include:

  • Reduced range.
  • Lock, unlock, or trunk release buttons do not work.
  • In push-button start models, your Mercedes-Benz fails to recognize your key fob.

Fortunately, replacing your Mercedes-Benz key fob battery is a simple DIY-project.

How Do I Replace My Mercedes-Benz Key Fob Battery?

  1. Release the emergency key.
  2. With the emergency key partly in its chamber, pull it away from the key fob, using it as a lever to lift the battery casing free. Alternatively, some fobs require you to fully remove the emergency key and use a small screwdriver to open the battery cover.
  3. Remove the old battery and insert the new one, ensuring it’s facing the correct way.
  4. Put the cover back on by placing it in its original position and either applying force or screwing it back in. Finally, put the emergency key back into the fob.

If your Mercedes-Benz key fob does not work after replacing the battery, the problem likely stems from broken battery contacts or dysfunctional buttons.
