^ mine did that to. I had to open the inside, look down in there and move the lock to lock/unlock. Watch the rod that moves, and which direction when you push unlock. Then, get down in there and push it a little further to completely unlock it.
Then, don't lock the doors... as least thats my solution as I leave the jeep empty and don't have keys for my doors anyways lol.
I was thinking, if I used the locks I'd probably pull the entire door panel and put a return spring in there to help it pull back to unlock all the way. You may also get away with moving the striker down slightly but no so far where the door won't latch.
