I'm not sure why but, my unlock exit won't work. I have an exit set to locked. On the door i have it set to use key on the door and the script says to unlock that exit. And after it's used on it I still can't go through the exit.

Make sure you're referring to the exit by the correct name in your script.

For example, if you have a "north" exit to "dungeon", your script needs to unlock the "north" exit, NOT the "dungeon" exit.
