I had left the lights on overnight and the battery in my old '02 CLK died. I also couldn't get the trunk open, but I could get the hood open and in there was a jumper terminal, onto which I attached a pair of jumper cables to provide power so that I could release the trunk. Then I recharged the battery. Maybe your car works the same way.
