What You’ll Need:
Before you get started, gather the following items:

- A small flat-head screwdriver
- Your 2011 Mercedes E350 key fob
How to Replace the Battery in Your 2011 Mercedes E350 Key Fob:
-
Locate the release button: On the back of your key fob, you’ll find a small, rectangular button. This is the release button for the emergency key.
-
Remove the emergency key: Gently press the release button and carefully slide out the emergency key.
-
Open the key fob: With the emergency key removed, you’ll notice a small slot where it was inserted. Insert the flat-head screwdriver into this slot and gently pry open the key fob casing. You should hear a slight click when it separates.

Replace the battery: Carefully remove the old CR2025 battery and replace it with the new one. Make sure the positive (+) side of the battery is facing upwards.

Reinsert the emergency key: Slide the emergency key back into its slot until it locks into place.
-
Test the key fob: Try locking and unlocking your car doors using the key fob buttons to ensure the new battery is working correctly.
Still Having Trouble?
If you’ve replaced the battery and your key fob still isn’t working properly, there might be a different issue. Here are a few possibilities:
-
Key fob programming: In some cases, you might need to reprogram your key fob after a battery replacement.
-
Key fob damage: Physical damage to the key fob or its internal components could prevent it from functioning correctly.
-
Car battery issues: A weak or dead car battery can also interfere with your key fob’s ability to communicate with your vehicle.
