Sounds like the lock is faulty. Thing is, with these lock they must be replaced by the dealer as Mercedes does not give out it lock information to aftermarket businesses.
Call your local Benz dealer to see what can be done. And oh yeah, get ready for a little sticker shock. I've had this happen to two of my cars before and it wasn't cheap nor expeditious.
