Help on locking level doors?

[Wyz]

You have probably a callback somewhere that when you pick up the key it calls the function AtriumDoorUnlock. Have you written AtriumDoorUnlock inside the key's entity tab?

Yes, the callback func is listed on the key. Is that my problem? Because my callback is a useitem, could that be what you're saying, the unlock function is called as I pick it up?
