I have a 2009 c class 300 mercedes benz I put my key in the ignition and it reads remove key from ignition radio comes on light comes on I can lock and unlock doors but car wont crank.
Where did you get the key? Mercedes or "Joe's Storm Door and Key Cutting Company?"
I remember reading something about the steering colum having issues with getting the signal from the key which keeps the car from starting. Heres the link so you can read it for yourself to see if this matches the same problems as your car. http://www.benzworld.org/forums/w204-c-class/1632510-08-c300-wont-start.html
