Will there be another season of Locke & Key?

Netflix confirmed that the third season of Locke & Key would be the last one back in April this year.

However, the show hasn’t exactly been cancelled and has ended naturally after a three season run, which had been the plan of the creator’s since the show began.

Locke & Key creators Carlton Cuse and Meredith Averill said: "Once we began working on the series, we felt three seasons was the ideal length to bring the story of the Locke family and their Keyhouse adventures to a satisfying conclusion.

"As storytellers, we are grateful that we had the opportunity to tell our version of Joe Hill and Gabriel Rodriguez’s incredible story exactly the way we wanted. We’re keeping the magical keys, though, for our own personal use."
