If the battery that powers the remote for the Mercedes A-Class suddenly dies and you cannot replace it, you can open and start the vehicle by performing a few steps. Press the small button on the back of the remote and pull out the metal key, then insert it into the hole located under the plastic cover of the driver’s door handle to remove it. You will have access to a lock that you will use to open the door.

Once seated in the driver's seat, place the remote in the cup holder on the side where a key is printed and by pressing the Start button, the vehicle will start.
