How to Easily Change the Battery in Your Mercedes Key

Is your Mercedes key fob starting to act up? Finding yourself repeatedly clicking at the doors, only to be greeted by silence? It's likely time to change the key battery. Luckily, this is a straightforward process you can handle yourself, saving both time and money you'd spend at the dealership.

Spotting the Signs

Know when it's time: A common indicator that your Mercedes key battery is low is a decrease in the effective range of the key fob. If you notice you're having to get closer and closer for your car to unlock, it's time for a replacement.

What You'll Need

Before diving into the process, gather these essential tools:

  • A new CR2025 or CR2032 battery (depending on your key model)
  • A small flathead screwdriver or similar tool

Step-by-Step Guide to Changing Your Mercedes Key Battery

Step 1: Remove the Mechanical Key

Start by sliding the black switch at the bottom of your key fob. This action will free the mechanical key. Slide it out carefully.

Step 2: Open the Battery Compartment

Once you have the mechanical key removed, use your flathead screwdriver to gently pry the back cover open. Be cautious and ensure that you don't apply too much force, which could damage the casing.

Step 3: Replace the Battery

You'll find the old battery inside the compartment. Note its position and orientation carefully before removal. Place the new battery in the same spot, ensuring the positive side (+) is facing up.

Step 4: Reassemble the Key

Snap the back cover into place until you hear a click, indicating it's securely fitted. Slide the mechanical key back into its slot. Test your key fob to ensure it's functioning correctly—try locking and unlocking the car from various distances.
