However, years later, still longing for Lucas, Ellie used the Echo Key at the well house to try to bring him back, only to bring back the entity that had possessed him – "Dodge" – instead. Ellie had called Mark about Rendell's murder so that he would use the Matchstick Key to immolate himself and keep the mapped locations of the other keys from Dodge.

In the present day, Ellie and Rufus take the Shadow Key and go back to their house to retrieve the crown.

## Production
### Background

Locke & Key was originally developed as a television series by the Fox broadcast network during the 2010–11 television season by DreamWorks Television and 20th Century Fox Television, with Josh Friedman writing the pilot script adaptation. Alex Kurtzman and Roberto Orci served as executive producers for the pilot, which starred Mark Pellegrino, Miranda Otto, Jesse McCartney, Sarah Bolger, Skylar Gaertner, and Nick Stahl. The pilot was not given a series order by Fox, though it was screened at the 2011 San Diego Comic-Con. At the 2014 San Diego Comic-Con, a feature-film trilogy was announced through Universal Pictures with Kurtzman and Orci expected to serve as executive producers.

### Development

On May 9, 2016, IDW Entertainment was reported to again be developing a television-series adaptation of Locke & Key. The novel's author, Joe Hill, was expected to write the pilot and serve as an executive producer. The project was developed in association with Circle of Confusion with the intent of pitching the series to cable networks and streaming services.
On April 20, 2017, Hulu gave the production a pilot order. The production was developed by Carlton Cuse with Hill and set to be directed by Scott Derrickson. Cuse was expected to serve as the series' showrunner and executive producer alongside Hill, Derrickson, Lindsey Springer, Ted Adams, and David Ozer. Production companies involved with the pilot were to include Carlton Cuse Productions and IDW Entertainment. On July 14, 2017, it was reported that Andy Muschietti was replacing Derrickson as director, as Derrickson was forced to drop out of the production due to a scheduling conflict. On March 27, 2018, it was reported that Hulu had passed on the pilot and declined to order it to series.
On May 29, 2018, the production was reported to be in final negotiations with Netflix for a series order. Netflix redeveloped the property and discarded the Hulu pilot. Due to scheduling conflicts, Andy Muschietti was not expected to direct the new pilot, but would continue to serve as executive producer alongside Hill, Cuse, Adams, Ozer, and Barbara Muschietti. Production companies involved with the new iteration of the project were set to include Genre Arts and IDW Entertainment. On July 25, 2018, Netflix officially gave the production a series order for a first season consisting of ten episodes. Aron Eli Coleite, Meredith Averill, and Rick Jacobs were announced as new executive producers. Circle of Confusion was the anticipated production company. The new iteration was created by Hill and developed by Cuse, Coleite, and Averill. The new first episode was written by Hill and Coleite, with Cuse and Averill serving as showrunners. Michael Morris directed the first two episodes and served as an executive producer.
In adapting the comic for the Netflix series, the fictional town where Keyhouse is located was changed from Lovecraft to Matheson, Massachusetts. According to Cuse and Averill, this change had been suggested by Hill; because of the comic's Lovecraftian themes, the setting's name was to honor author H. P. Lovecraft, but Hill wanted to honor author and screenwriter Richard Matheson for the series, instead.
Although the series had not yet received an order beyond its first season, writing for a potential second season began ahead of the series' first-season premiere. On March 30, 2020, Netflix renewed the series for a second season. On December 18, 2020, ahead of the second-season premiere, Netflix renewed the series for a third season. On April 6, 2022, it was announced that the third season would be the show's last, as planned after the success of the first season.

### Casting

In August 2017, Frances O'Connor and Jackson Robert Scott were cast in the pilot's leading roles. In September 2017, Megan Charpentier and Nate Corddry were reported to have joined the pilot's main cast. In October 2017, Jack Mulhern, Danny Glover, and Owen Teague were cast in starring roles in the pilot.
Alongside the announcement of the production's move to Netflix, it was revealed all of roles would be recast with the exception of Jackson Robert Scott as Bode Locke. On December 19, 2018, Connor Jessup and Emilia Jones were cast to replace Mulhern and Charpentier, respectively. In January 2019, Sherri Saum, Griffin Gluck, Steven Williams (replacing Glover), Darby Stanchfield (replacing O'Connor), Laysla De Oliveira, and Kevin Alves joined the cast with Gluck, Stanchfield, and De Oliveira in main roles and Williams and Alves recurring. In February 2019, Petrice Jones and Thomas Mitchell Barnet (replacing Teague) joined the main cast; Asha Bromfield and Felix Mallard were added in recurring roles.
Mirroring their appearances as characters in the comic book, creators Joe Hill and Gabriel Rodriguez had cameo appearances in the first-season finale as paramedics.
On September 30, 2020, Aaron Ashmore and Hallea Jones were promoted to series regulars while Brendan Hines was cast as a new series regular for the second season. On October 6, 2021, it was reported that Kevin Durand had joined the cast as a new series regular for the second season.

### Filming

Principal photography took place from February 11 to July 5, 2019, in Hamilton and Toronto, Ontario, Canada. Scenes within the fictional Matheson, as well as some other exteriors, such as the outside of the Drowning Cave, were filmed in Lunenburg, Nova Scotia. Keyhouse itself was a constructed set and shot at Cinespace Film Studios in Toronto along with other interiors. The second season began filming on September 21, 2020, and concluded on April 16, 2021. The third season began filming on May 3, 2021, and concluded on September 17, 2021.

### Music

Torin Borrowdale composed the series' score. When writing the main theme, Borrowdale wanted to elicit a feeling of magic and whimsey that would come with exploring a house with magical keys for the first time. Borrowdale implemented a solo cello in a low register for Dodge's theme to capture both the beauty and the darkness of Dodge's character. For Bode's theme, he created a simple tune that would be adaptable to the varying situations Bode got himself into, and variations on the theme were used to reflect the mood of the scene. The soundtrack was released on March 13, 2020.

## Release

In December 2019, Netflix announced that the series would be released on February 7, 2020, in the US and Canada. On January 8, 2020, Netflix released an official trailer for the series. A world premiere was held on February 5, 2020, in Hollywood, California. The second season was released on October 22, 2021. The third and final season was released on August 10, 2022.

On Rotten Tomatoes, the second season has an 83% approval rating with 12 reviews, with an average rating of 7.7/10.

The series received generally positive reviews from critics, with the score, set design, and visual effects singled out as highlights.

The performances of Jackson Robert Scott and Laysla De Oliveira received particular praise.
USA Today claimed that the series was "nearly as strong a debut as Stranger Things was in 2016, but it [needed] a few tweaks to jump the hurdle between good and great." IGN credited its portrayal of trauma and the visual effects, and praised the performances of Scott and de Oliveira, while criticizing the series for failing to consistently build tension.
Polygon's review was more negative, criticizing the decision to make the television adaptation emphasize the coming-of-age story and fantasy elements, while glossing over the horror elements and haunting visuals of the source material. In particular, the review criticized the uninteresting subplots and inconsistent pacing.
