Pay close attention to the sound of the engine while it cranks over. The cylinders shd all sound the same as it cranks. If it sounds funny, the head gasket has been damaged. That is an expensive repair

My first guess is a dead batter. Be REAL careful in getting the cables correct if you jump it off.

Car battery might be discharged , or try key lock unlock to calibrate key, hope this helps good luck.

In some cars, you have to depress the switch a little bit further in to start it. I am not familiar with this Mercedes but it is worth trying. In some cars, the key fob has a disabling mode if the key is not activated, the car will not start.

I would say it is the ignition switch. You can try to get the steering wheel unlocked moving it, but usually when the key won't turn, it is the switch or security system. You will need to reset it to find out. Call the dealership if you don't have it.
