The battery to my 1993 300-SE went dead. It's located in the trunk of the car. I attempted to "jump it off", using another battery & cables, which didn't work. I closed the trunk lid, to try later with another battery. Later, I was unable to open the trunk lid at all. I've tried just about everything, except a wrecking bar. Does anyone know how to open trunks in this situation? Is it tied in to the car's security system & need battery power? There's supposed to be some "jump poles" under the hood, but I don't have a clue as to where.
