Having Trouble making a door lock and close behind me. Help Please! :)

[Watskeeee]

So far, this is my coding of the first half.

void OnStart()
{
AddUseItemCallback("", "key01", "doorroom01", "KeyOnDoor", true);
AddUseItemCallback("", "key02", "doorroom02", "KeyOnDoor", true);
}

AddEntityCollideCallback("Player", "RoomofSecretsArea", "CollideRoomTwo", "true", 1);
}

Void CollideRoomTwo(string &in asParent, string &in asChild, int alState)
{
SetSwingDoorClosed("doorroom01", true, true);
}


void KeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("doorroom01", false, true);
PlaySoundAtEntity("", "unlock_door", "doorroom01", 0, false);
RemoveItem("key01");
}


void keyfunc(string &in asEntity, string &in type)
{
SetEntityActive("servant_brute_1", true);
StartPlayerLookAt("servant_brute_1", 15, 15, "");
AddTimer("monstertimer", 2, "monstertimer");
ShowEnemyPlayerPosition("servant_brute_1");

}


void monstertimer(string &in asTimer)
{
StopPlayerLookAt();
}





I know theres something wrong in there, but I can't see where..
