Hello
So there I was, eating my lunch in the back seat of my 300SD. The "lunch is over" beep came from inside the work place. I reached over, pushed the button on the driver side door down to lock all the doors. And then I hurried inside. And yes, you guess it, the keys are still in the car. I don't have the Valet key so I basically need to get into the car, without the keys.

Please someone help. Thanks a lot
