Trying to open and close a door with a lever

[GraphicsKid]

Closing part is pretty easy, but the darned thing won't open. As soon as it's closed, it sort of latches shut. SetSwingDoorClosed("blah blah, false, true") does nothing. If I put a force on the door body, it just looks like someone is throwing themselves against it from the other side... it sort of bucks for a second, but stays shut. This is a prison door btw, not one of the usual wooden ones.

Also, I'd like to make it so the door cannot be moved by the player other than by using the lever.
