If you look at the article here, you will see that there is a plastic piece that connects the door lock mechanism to the actual key and door lock. These plastic pieces have a tendency to break. Replacing them is relatively straightforward, but you need to remove the door panel and get in there to reach them.

I should say it does turn one way to unlock but not the other way
