So, you bought the car and it worked for two weeks. You didn't do anything between the last time it worked and the time it didn't work? The key worked one day and the next day it would not turn? Odd.

The Mercedes part number for the lock cylinder lubricant is 001 989 26 51 10. It's about $15. My local dealer had it in stock. The service manual says to "spray the cylinder with grease" but I think I would follow merc s500's advice and try applying it to the key first. I did that to my wife's C car and it's been fine for years.

Unbelievable...I'm guessing this is not your daily driver to be.

Follow the earlier post and take the cylinder out and try it then.

Personally, I would get it into a shop and get the beast on the road.
