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



////////////////////////////

////////////////////////////
// Run when leaving map
void OnLeave()
{

}

////////////////////////////
// Run first time starting map
void OnStart()
{
AddUseItemCallback("", "Awesome_key", "Awesome_door", "ABC", true);
}

void ABC(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked( "Awesome_door", false, true);
PlaySoundAtEntity("", "unlock_door.snt", "Awesome_door", 0, false);
RemoveItem("Awesome_key");
}

Check that the names match and delete .map_cache if there's any.
