Locate the release button: Examine your Mercedes key fob. You’ll find a small, discreet button, often on the back. This is the key to unlocking your key fob’s inner sanctum.

Swap out the old battery: Inside, you’ll spot the tired CR2032 battery. Carefully remove it and replace it with the fresh one, ensuring the positive (+) side faces up.
