Electrical problem
1994 Jaguar XJ6 6 cyl Automatic

Hi
I'm having a problem opening my trunk.
Right now, the battery is dead in the car (the battery is in the trunk) and the trunk is locked. I can't unlock the trunk with the key because manually turning the key for some reason will NOT unlock it (it turns in the hole, but will still not unlock). There is no button to press to open the trunk. I have tried removing the back seats, however, they are bolted in, and i could only remove the bottom of the seats. If you no anyway I can get into this trunk, its important!, even if it includes taking out the seats (WITH GOOD INSTRUCTIONS!..I'm no mechanic ..)
PLEASE HELP!!
ITS REALLY IMPORTANT!!!
