Key to a level door

[MaTPlays]

Not working, maybe I've got something wrong:
void OnStart()
{


AddUseItemCallback("", "Keymaindoor", "Door_1", "UseKeyOnDoor_1", true);
}


void UseKeyOnDoor_1(string &in asItem, string &in asEntity)
{
SetLevelDoorLocked(asEntity, false, true);
PlaySoundAtEntity("", "unlock_door.snt", asEntity, 0, false);
RemoveItem(asItem);
}
