I'm probably missing something but this door won't unlock

[liamthespy]

AddUseItemCallback("", "kitchenkey", "kitchendoor", "Kitopen", true);
}

void kitopen(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("kitchendoor", false, true);
PlaySoundAtEntity("", "unlock_door", "kitchendoor", 0, false);
}

I've checked over the syntax and the names like 100 times, what am I missing? it's just a simple key-opens-door situation and I've done it a million times, why is this not working?
