The Locke family uncovers more magic within Keyhouse, while a new threat -- the most dangerous one yet -- looms in Matheson with plans of his own for the keys. From Carlton Cuse (Lost, Bates Motel) and Meredith Averill (The Haunting of Hill House), Locke & Key is a coming-of-age mystery about love, loss, and the unshakable bonds that define family. Locke and Key on Netflix is the television adaptation of the best-selling comic book series by Joe Hill and Gabriel Rodriguez for IDW Entertainment.
