He must have followed the tutorial from the wiki.

void OnStart()
{
AddUseItemCallback("", "ITEM", "DOOR", "FUNCTION", true);
}

void FUNCTION(string &in item, string &in door)
{
SetSwingDoorLocked(door, false, true);
PlaySoundAtEntity("", "unlock_door", door, 0, false);
RemoveItem(item);
}

I didn't know it still worked if you did that. I get everything from the Engine Scripts page.
