This thread got my curiosity going.....not too hard to do.....so yesterday when the trunk happened to be open, I pulled on the cable and heard a click at the trunk lock. So something was happening. I closed the trunk and used the key to lock the front door. The trunk locked. I pulled the cable and nothing happened.
I was able to unlock the trunk with the key--turning counter-clockwise and pushing in the button at the same time. If I don't lose the key, I am OK.
