Im having a little problem with the lock mechanism on the rear hatch of my 71. i dont have a clue which key unlocks it, is it the ignition key?? I replaced the tumblers in the ignition and threw the old key in the pile so I'd have to find it again. i have one that works for the doors but it wont work on the hatch......i dunno!?!? Your right I dont understand the jeep thing!?
