Follow these steps on how to replace your Mercedes-Benz key fob battery with ease:
- Grip the latch located at the end of the fob and gently pull to remove the emergency key. It should slide out smoothly on its own.
- After the key is released, observe the end of the key fob where a visible slot becomes apparent.
- Insert the emergency key into this slot, applying gentle pressure to open the battery compartment cover.
- Once the cover is open, carefully remove the old battery from its compartment, noting its orientation for proper replacement.
- Take the new battery and insert it into the compartment, ensuring the positive (+) and negative (-) sides align correctly with the markings inside.
- Close the battery compartment cover by pressing it shut until you hear or feel it click securely into place and re-insert the emergency key to its original location.
