Locke & Key to end with its upcoming Season 3

Deadline

According to Deadline's Nellie Andreeva, Season 3 was always planned as the final season. "In fact, I hear that, following the breakout success of Locke & Key‘s ten-episode first season, Netflix approached the series’ creative team with a plan for a three-season run consisting of a 10-episode second season and an eight-episode third season," reports Andreeva. "That fit the vision of Locke & Key executive producers/co-showrunners Carlton Cuse and Meredith Averill for how to tell the story and when to wrap it." Cuse and Averill added, in a statement: “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."
