That should work for you. The errors were caused by
1) Inaccurate function names.

Example:
Setswingdoorlocked won't be read by the engine, as your capitalization was incorrect
SetSwingDoorLocked is the proper way of writing it.

2) Incorrect Callback

You had usedkeyondoor as your target callback, as definted by the AddUseItemCallback, but your function was named keyondoor. Therefore, the engine won't be able to find the function you called for, and what you want to happen simply won't.
