Except the homeowner doesn't own the alarm. It's more like a mapmaker allowing access to the index of the map, which a clever person happened to figure out revealed where some houses with broken locks are. And the mapmaker has the decency to say "hey, let's see if this visitor is at least human" before allowing you to proceed from the index to the map itself. Ok, now the mapmaker has solid evidence that this human is doing something shady. Human, you are on notice.
