2009 C300 Car Won't start

I have been having trouble starting the Car. Door unlocks and locks. Checked Battery, fuses everything is fine. After some playing around started then 2 weeks later same car would not start. Finally took to dealer here is what they said

They suspect it's something to do with my key, and suggested that I get a new one and have them program it to my car, but said they can't guarantee that's going to solve what ever the problem was. They wanted to charge me $485 for a new key and programming - but no guarantee that will fix the problem.
Car starts fine now but I am sure this will happen again.

Any help shedding some light would be greatly appreciated.

Does it crank and not start or does it not crank?

Could be anti theft issue. If the dealer or an indie mercedes mechanic put a Mercedes specific code reader on it, they could read the stored codes and do diagnostics on it to get to the heart of the issue. I don't like throwing parts at it.

Also sounds like you're a new dealer
