2002 W210 key question
A friend of mine at work just bought a 2002 E320. He asked me if the battery on the key goes dead will the car still run once he uses the metal key to get in and puts the key in the ignition. Doesn't the car continuously looks for a reponse code from they key to make sure it is the right one? Also he doesn't think that the dash is real leather. Is it?
