If you haven't had any previous difficulty it might be due to a worn ignition switch plus the very cold weather. Do you have another key that could be used. Sometimes that will solve the problem. Don't force the key. If it won't turn be cool a do a couple of things. One, you could warm up the switch with a hair dryer. Also, warm up the key as much as you can, with the hair dryer, a candle or lighter. If all that fails, try vibrating the switch with an electric razor while gently trying to turn the key. If all that fails, and probably even if you can get it to turn, you are due for a new ignition switch. Diesel Giant over in the diesel section has a nice pictorial on how to change the ignition switch. All the Benz switches are about the same.
