Hi, when you try to close the door does it close flush and not latch or is the latch already locked and it is preventing the door from closing?
If the latch is already locked you need to use a screwdriver to try to pry the latch lever back around to the open position while a helper pulls on either the inner or the outer handle.
I would try pulling on the inner handle and doing the same thing. It may help if you take a look at the other door so you can see how the latch rotates.
Ok, It's the same idea just a little more difficult.
Sorry I was pulled away
The latch rotates and locks. I would try rotating it back. You might also try doing it while your helper presses the trunk release button.
