Gather the Required Tools
Before starting the battery replacement process, gather the necessary tools. For changing the battery on a Mercedes key fob, you will need:
- A small Phillips head screwdriver
- A replacement battery (ensure it is the correct type for your specific Mercedes key fob model)
Step-by-Step Guide to Change the Battery
Follow these step-by-step instructions to change the battery on your Mercedes key fob:
Step 1: Locate the Battery Compartment
On most Mercedes key fobs, the battery compartment is located on the backside of the fob. Look for a small groove or indentation on the side that can be used to pry open the compartment.
Step 2: Open the Battery Compartment
Use the small Phillips head screwdriver to gently pry open the battery compartment. Apply slight pressure until the compartment opens, revealing the battery inside.
Step 3: Remove the Old Battery
Once the battery compartment is open, carefully remove the old battery from its slot. Pay attention to the battery’s position to ensure you insert the new one correctly.
Step 4: Insert the New Battery
Take the new battery and insert it into the compartment, following the correct orientation. Match the positive (+) and negative (-) markings on the battery with the corresponding markings inside the compartment.
Step 5: Close the Battery Compartment
With the new battery securely in place, gently close the battery compartment by pressing it back into position until it clicks or snaps shut. Ensure that it is firmly closed to prevent any issues with the key fob’s functionality.
Step 6: Test the Key Fob
Once you’ve successfully replaced the battery and closed the compartment, test the key fob to ensure it is working correctly. Press any of the buttons on the key fob, and if you see a response from your Mercedes (such as the vehicle’s lights flashing or doors locking/unlocking), it indicates that the battery replacement was successful.
Tips and Recommendations

- Always use the correct type of battery recommended by Mercedes. Refer to your owner’s manual or consult a dealership to ensure you have the right battery.
