Replacing the Remote Battery of Mercedes Cars

Model: Mercedes Mercedes Various
Part: Key

When the batteries powering the two-button black remote of Mercedes cars run out, you need to replace them. Remove the metal key from the remote. Using a small flathead screwdriver, lever the edge of the battery housing until it disengages, then pull it out. Using the screwdriver, extract the exhausted batteries. Replace them with two new CR2025 batteries, ensuring correct polarity during installation. Insert the block back into its housing and press until you hear a click, then reinsert the metal key into the remote.
