I'm new to this board but...i have a problem, I guess someone here can tell me how big, I have a 99, CLK 430, when i got the car i was never able to use the keys to open the trunk, it wont even turn. I have to use the remote to open it. Any way my battery is dead.....I cant get into the trunk cuz the key dont work, *plus* my cousin locked the back seat from folding down....So i dont know what position im in right now! I cant get in the trunk at all to jump start the car. Is there anything i can do?
