'Locke & Key's Main Filming Locations Might Surprise You

The Netflix horror series Locke & Key centers around the magical and mysterious Keyhouse. The show itself is set in the fictional town of Matheson, Mass., in the New England region.

But does filming actually take place in Massachusetts?

The answer is no, but the Locke & Key locations are picturesque and picked to be the show's backdrop for a reason. Allow us to take you on a behind-the-scenes journey to where Seasons 1 through 3 of the Locke & Key series are actually filmed.

Seasons 1 and 2 of Locke & Key were filmed primarily in Toronto, Canada. According to a report from the Radio Times, the exterior of the famous Keyhouse is a combination of a front facade that was built in the Canadian countryside and CGI.

Many exterior and interior shots for Locke & Key were shot at Cinescape Film Studios in Toronto. The aforementioned Radio Times report notes that interior shots set in the Drowning Caves were filmed at Cinescape.

Exterior shots of the Drowning Caves were filmed in Lunenberg, a town located in Nova Scotia.

According to a report from Decider, a majority of Matheson shots were filmed in Lunenberg. Another interesting report from Narcity goes into further detail about specific Ontario spots that are seen on Season 2 of Locke & Key.

For example, the interior of the movie theater in Season 2, Episode 1, which centered around the premiere of Kinsey Locke's (Emilia Jones) film Splattering, was filmed at the real-life Ontario movie theater Playhouse Cinema.

Ontario's Mill Race Park served as a stand-in for the city of Bath, England during an exterior scene with Jackie Veda (Genevieve Kang) and Tyler Locke (Connor Jessup) in Season 2, Episode 4. For context, during the episode, Tyler uses the Anywhere Key to send Jackie to Bath for her birthday.

According to the same Narcity report, Kingston Market Square in Ontario was also used for shots of Tyler and Jackie's romantic birthday getaway in Bath. Another notable Ontario-based location was Westfield Heritage Village in Rockton. The village was also used to film interior scenes of the key-making cabin.

Season 3 of Lock & Key — which premiered on Aug. 10, 2022 — was filmed in Ontario and Nova Scotia, specifically in Toronto, Mississauga, Woodstock, and Lunenburg, per The Cinemaholic. Scenes involving the Keyhouse and the Drowning Caves were filmed in Cinespace Film Studios, just as they were in Seasons 1 and 2.

Mississauga's Lakeside Promenade and Woodstock's Museum Square were also used for the series.

In Lunenburg, Montague Street, Bluenose Drive, and 9 King Street were backdrops for Season 3, standing in for the fictional town of Matheson.
