If your Mercedes-Benz C230 will not turn over, there may be a number of reasons why this is happening. Here is a checklist to aid in diagnosing the problem:
Battery Problems
Is the battery charged?
Are the terminals of the battery clean and properly attached?
Attempt a jump-start to eliminate a dead battery.
Starter Motor
Check for a click when you turn the key. One click may signal a bad starter.
If you hear rapid clicking, it may be a dead battery or poor contact.
Ignition Switch
Make sure the key is turning easily. Occasionally the ignition switch will also malfunction.
Neutral Safety Switch (automatic transmission only)
Make sure the gear shift is in 'Park' or 'Neutral.'
Try to start the car in both positions.
Fuses and Relays
Inspect the fuse box for blown fuses associated with the starting system.
Security System
Is the security light on? The car's anti-theft system may be keeping it from starting.
Try turning the key with the spare key.
Fuel System
You may hear a humming sound from the fuel pump when you turn the key to the "on" position.
Check to see if there is fuel in the tank.
Error Codes
If you have an OBD-II code reader, you can check for error codes. They can provide hints regarding problems such as crankshaft position sensor failure.

I had this on an XC70 recently. (The key would turn to get the dashboard lights on, but that was it). The lock was broken and needed to be replaced. But the AA man did manage to force the key to work and this enabled me to use car for a few days awaiting the lock with the same code as before.
