For the Mercedes SLK 200:
I've got a flat battery and the electronic key won't open the doors. I have no other key. Is there a solution to this problem?

Hi, sorry for the long wait on this question. When the battery is flat you use the metal key blade from your remote to unlock the door with the key. If that does not work you will need to raise the car and connect 12 volts to the starter motor to back feed the circuit so that you can unlock the car with the remote.

Let me know if you need further assistance.
