Model: Mercedes Mercedes Various
Part: Key

When the battery that powers the remote control for opening and closing the doors of Mercedes cars runs out, you need to replace it. Press the small button on the back of the remote, under the keyring, to slide out the key blade. While pressing the button, remove the rear cover. On one side, you will find the battery compartment, which you can slide out using your fingers.
