You can get a new key from Mercedes. Do you have the documents of the car? If you don't have the keys I guess you don't have the documents either, because in mine there was a code which was the "Key replacement code".
But if I recall correctly, I had to prove it was my car first. You can do that like the poster above said, or you can show them your documents when you purchased the car.
