2007 Mercedes Benz keys locked in the trunk ..help
I worked on Mercedes any years but none newer than the late 90's models but I can tell you it can be done by removing the back seat. You will most likely run into a gas tank that is in the way but might be able to see them and fish them out with a coat hanger or something. The tank is removable but for the trouble it is I would call a locksmith.
