Obviously you took it to someone that did not know anything about Mercedes, I am without insufficient information to determine if it was the key problem, did the key over the lock? Did the engine crank? Most likely the only problem you had was the batteries were low or dead in your remote key, or if you notice on the barrel of the key there is around black plastic ring that is your key recognizer, it requires special tools only from the dealer to determine and program recognition problems with the key. I recently had to take a customer's Mercedes to the dealer with the same problem and cost $64 for them to reprogram the key.
