If the show gets picked up for a second season, there are a lot more keys from the comics that could potentially come into play.

The Music Box Key also appeared in the comics but Kinsey and Gabe using it to puppeteer Eden in the lunchroom is a creation of the show. Another small but notable difference is the Plant Key, which does exist in the comics but is used here in a different manner: to trap Duncan Locke's bottled memories inside of the tree in the garden of Keyhouse. The second is The Mirror Key, which opens up a terrifying world inside of a mirror which Dodge uses early on to try and trap Bodie and his family inside. The first is the Matchstick Key, which gives its user the ability to start fires and is used by Mark Cho, Sam Lesser, and Tyler. Speaking of new keys, we see two more that have never existed prior to the show.

Though no Identity Key exists within the original comics, this one is more of a mashup of two other keys - the Skin Key and the Gender Key - that do appear in the Locke & Key comics, rather than an entirely new creation. One of the other big changes in regards to the keys is the newly-invented Identity Key which Lucas/Dodge/Gabe uses throughout the first season. "I don't think you see other shows going inside someone's head or kind of trying to come up with the metaphorical comparisons," he said. “So we had to figure out how we were going to translate the Head Key to the screen and we thought about it a lot and we decided that really we needed to kind of break down for each character what would be the essential elements that we would see in their heads." It's a diversion from the source material that works surprisingly well on screen and Cuse had a theory why. There's this splash page of Bode's head that may be the greatest thing in the Locke and Key comic book, but it's impossible to actually do that on television,” Cuse said.

Play "There's so much incredible imaginative art in the comic and some of those things translate well to the screen and others are impossible.
