The Locke family (minus Bode) looking at something alarming.

The third and final season of Locke & Key will arrive on the streaming service on August 10, and the streamer calls it the most dangerous threat yet. You can check out the new trailer.

Multiple villains are coming from the looks of it. Locke & Key has yet to achieve the pop-culture-obsession heights of, say, aStranger. Keeping the series to three seasons is a way to make sure the stakes escalate for the core characters while also keeping the story intimate.

The final eight episodes of Locke & Key will be available on August 10.
