Locke & Key

This plot is presented in chronological order.

In 1775^[1] during the American Revolution, a group of Rebels, hiding in a sea cave in Massachusetts Bay beneath what will one day be Keyhouse in the town of Lovecraft, discover a portal to another dimension, the plains of Leng. It is filled with demons who can mesmerize anyone who sees them and possess them through touch; two men are possessed over two days, and they kill several rebels. However, when the demons attempt to enter the real world without possessing someone, they are transformed into "whispering" iron, which young smith Benjamin Locke forges into a variety of magical keys. The first key he makes is the Omega Key (which has an Omega character on the head) that seals the entrance to the dimension. The magic of the Keyhouse gradually evolves over the years, including a spell that causes occupants to forget about the keys and the magic of the house when they pass their 18th birthday. In 1988, a group of teenagers, having used the keys extensively in their high school years to their great delight, decide to open the black door with the Omega Key, hoping to trick a demon into entering the real world in order to provide more metal with which to make more keys. Rendell Locke's younger brother Duncan follows the group into the cave, but he is mesmerized by demons in the open door, and attempts to walk through it. He is stopped by Lucas "Dodge" Caravaggio, who accidentally puts his hand through the doorway and is possessed by a demonic being. He plots to kill his friends and enslave the others; Dodge kills several and causes another to lose her memory. He also extracts a part of his spirit to be hidden in a jar in the home of Ellen "Ellie" Whedon, one of the surviving friends, as a contingency plan. Dodge is finally killed by Rendell before he can force more people to be possessed. Rendell discovers a small piece of "whispering" iron from the sea cave and disguises it as a fishing lure.

Around 2010, the fragment of Dodge's spirit partially possesses Ellie, who then conjures the rest of Dodge's spirit in the physical world at the magical well at Keyhouse, but Dodge is trapped within the well house. In 2011, Dodge's spirit reaches out to a young, abused prodigy, Sam Lesser, and convinces him to force Rendell to give him the Anywhere Key (which will allow Dodge to escape the wellhouse) and the Omega Key. When Rendell refuses, Sam murders him, but Sam is then incapacitated by Tyler, Rendell's oldest son, and captured by the police. The Locke family, children Tyler, Kinsey, Bode, and mother Nina, move across the country to Keyhouse, reuniting with Duncan, and begin discovering the house's secrets. Sam escapes prison with Dodge's help and follows the Lockes to Massachusetts. Sam attacks the family again at Keyhouse, but Dodge also tricks Bode into bringing him the Anywhere Key in case Sam fails again. Dodge escapes from the wellhouse with Bode's help, kills Sam, and returns to Lovecraft in the same body as he had thirty years before.

Dodge intimidates his way into living in Ellie's home, who is now a teacher at the same high school she originally attended with Dodge, and where Tyler and Kinsey are enrolled; Dodge also re-enters the school under the guise of a new student and Ellie's cousin. Over the next year, Dodge secretly tries to recover the various keys – particularly the Omega Key – from the children, collecting many, though hindered by Tyler and Kinsey. Dodge is eventually discovered but manages to switch bodies and possesses Bode before they can kill him. Now free to explore the house as Bode, Dodge finally finds the Omega Key and plans his takeover during the after-prom party in the sea cave. Demons possess several students, and many others are killed. Dodge is ultimately undone by Tyler, having re-discovered the "whispering" iron from his father; he forges an "Alpha Key" with Duncan's help, which can exorcise a demon from the possessed soul, though it is fatal to the physical host. Dodge spirit in Bode's body is forced back into the well, killing the spirit again, though Bode's empty body is cremated before Bode's soul has a chance to return into it.

In the epilogue, Tyler conjures Dodge's spirit again and uses the Alpha Key to finally exorcise Dodge from Lucas' soul, allowing Lucas' unpossessed soul to finally rest in death. Tyler uses the well's magic to speak with his father one last time. Finally, Tyler restores Bode's spirit to his physical form using the Animal Key.

The narrative of Locke & Key has a three-act structure, with each act covering two story arcs. Act One's first story arc, Welcome to Lovecraft, was a six-issue limited series published by IDW Publishing. The first issue of Welcome to Lovecraft was released on February 20, 2008, and sold out in a single day, requiring a second printing to be done immediately.^[2] The second arc of Act One, Head Games, commenced with the release of the first issue on January 22, 2009.^[3] The actual Head Games story was printed in four issues, with a standalone prologue ("Intermission" or "The Joe Ridgeway Story") and a standalone conclusion ("Army of One").^[4]

The first storyline of Locke & Key Act Two, Crown of Shadows, began in late 2009.^[5] The second storyline, Keys to the Kingdom, began in August 2010.

The first storyline of Act Three was announced as Time & Tide,^[6] but was retitled Clockworks.^[7] The second, and concluding, storyline is entitled Alpha & Omega.

Originally, the plan was to release the first five-story arcs in a monthly format with the sixth arc published as an original graphic novel. The plan changed, and the concluding story arc appeared in monthly installments.^[8][9][10]

In the universe of Locke & Key, there are many keys created from whispering iron that have different magical properties. Some of them are extensively featured in the series, while others are featured very briefly. The known keys are:

• Alpha Key: Created by Tyler Locke. Removes demons from possessed people's souls when inserted into their chests. It instantly turns a demon into whispering iron, so if the demon is still inside the host, the key's effect is fatal.
• Angel Key: Gives the user control of a winged harness that grants the ability to fly.
• Animal Key: Used on the right door in Keyhouse, it allows the user to travel through the door and transform into an animal. It is unclear whether they have a choice in the matter. It appears that the key assigns the animal according to some spiritual affinity. Returning through the door transforms a person back into a human. This works for human ghosts that have possessed animal bodies. Animals may also transform into humans if they enter through the opposite side of the door.
• Anywhere Key: Opens a door to anywhere the bearer can visualize in their mind. It is also capable of allowing Echos to leave the well house unharmed.
• Chain Key: A large chain, ball, and shackle-shaped key. Controls the Great Lock, which guards the catacombs with entangling chains.
• Creation Key: Resembling a pencil, this key causes anything drawn with it to become real, living, or otherwise. These things can also be erased by touching the other end of the key to them.
• Demon Key: When held against the spine of a person, a lock will appear. Upon being inserted, the victim becomes possessed by a demon.
• Echo Key: Allows entry to the Keyhouse wellhouse and, with the Echo Key in hand, allows a person to return a spirit from the dead to the world of the living. Leaving through the wellhouse door, however, banishes the spirit back to wherever it came from. This also applies to spirits that have possessed living bodies using the Ghost Key.
• Enigma Key: The purpose of this key seems to be intentionally unknown.
• Gender Key: Unlocks a half-sized door between rooms, which changes the sex of a person who enters it.
• Ghost Key: When used in the right door in Keyhouse, it separates the soul from the body of whoever travels through the door. The body falls dead while their ghost is free to roam the Keyhouse grounds. Ghost souls can inhabit any other bodies nearby and clash with other ghosts. If the door is closed while the user is a ghost, they will become permanently separated from their own body. If the user is possessed by a demon, the demon will become visible when the user is a ghost, appearing to be physically attached to their spine.
• Giant Key: This physically large wooden key, once inserted into a keyhole-shaped window in Keyhouse, transforms the bearer into a massive giant.
• Grindhouse Key: Transforms whatever door it opens into a giant fanged mouth that consumes whatever enters it.
• Harlequin Key: Unlocks the Harlequin Wardrobe and allows objects not normally inside to be seen.
• Head Key: Inserted into the base of someone's head, it allows one to peer inside the mind of a person, where memories and mental concepts (including "sanity" itself) are represented as tiny beings. The memories can be removed and swapped between people. Books inserted into a head with the Head Key transfer their contents to the bearer of the key, though in such a situation, the knowledge of the text is accurate but superficial.
• Hell Key: The bearer is automatically the Lord of Hell and can open the gates of Hell.
• Hercules Key: Embedded in a necklace, it grants the bearer considerable strength and bulk. The necklace was replaced by a belt in the Netflix series.
• Identity Key: Upon inserting into the base of one's chin, the bearer can change any aspect of their appearance, including clothes, body, or even gender. Also allows a bearer to forcibly change the appearance of others. However, the new appearance cannot match that of any existing person, and the user has to create a new face in their mind.
• IDW Key: Opens an outhouse in the woods bearing the eye of the IDW Comics logo. Once opened, the outhouse summons characters from other IDW comic books.
• Keyhouse Key: A large hammer-shaped key that fits into a stone slab and regenerates the Keyhouse after it is destroyed.
• Matchstick Key: Creates fires when inserted into a door or touched to an object, including a body. Shaped like a burning matchstick.
• Mending Key: Opens a magical cabinet in the Keyhouse into which a broken object can be placed (the cabinet can resize itself to the size of the object). Once the object is locked inside the cabinet, it is repaired. While it can heal severely wounded people to some extent, it apparently cannot resurrect the dead.
• Mirror Key: When inserted into a mirror, it allows the user to open a doorway to a parallel-pocket universe, called the Prison of the Self. This key affects a mirror's reflection if it is held toward a mirror, as it makes the reflection eerily pleasant and beckons the person to enter. The user is then enticed to come into the mirror by their reflection, and upon entering, they find themselves in a dark, empty abyss.
• Moon Key: Allows the user to reach and open the Moon like a door, which allows the user to pass on to the afterlife peacefully. Inhabitants who cross the door see the living world like a stage they can observe, and the afterlife like the backstage of a theater.
• Music Box Key: Inserted into a magical music box, it will cause the box to play a song that compels whoever is listening to obey its lyrics. Whoever turns the key can supply the commands. Commands are carried out so long as the music is playing and the listener can hear it.
• Omega Key: Opens the lock on the demonic door. The first key to be created.
• Orchestra Key: Inserted into a gramophone, this harp-shaped key will summon an orchestra composed of miniature humans.
• Owl Key: Gives the user control of a mechanical owl.
• Philosophoscope Key: Gives access to a device that allows viewing of various people and places, including concepts such as the user's truest love, greatest enemy, and future place of death.
• Reali Key: Allows passage to alternate dimensions.
• Shadow Key: Allows its wearer to control shadow creatures, and even the shadows of other people. Shadows are capable of interacting with the material world (often violently) but can be rendered immaterial by bright light. Embedded in a crown, the key is a tremendous source of power for the wearer.
• Skin Key: A key with a gazing mirror on its handle, it can change the ethnicity of whoever is using it.
• Small World Key: Unlocks a dollhouse replica of Keyhouse, allowing the user to see anything in Keyhouse in real-time. Any interaction with the unlocked dollhouse also occurs within the actual house, such as a house spider entering the dollhouse, magically emerging as a giant spider within the real house.
• Snow Globe Key: Traps the user inside a snowglobe resembling Keyhouse.
• Splody Key: Resembling a cartoonish stick of dynamite, this key causes explosions in any building it is used within.
• Squirrel/Undertree Key: Controls squirrels.
• Stamp Key: Allows the bearer to send postage through alternate dimensions and timelines.
• Sword Key: When inserted into the handle of any sword, it allows the sword to cut through any object.
• Tempus Fugit Key: Can turn the bearer into an older version of themselves, possibly other ages.^[11][12]
• Timeshift Key: Operates a grandfather clock that allows a user to observe (but not interact with) past events. The clock is limited to a specific time period: the earliest date one can visit is January 13, 1775, and the latest is December 31, 1999.
• Teddy Bear Key: Animates and controls stuffed teddy bears.
• Thorn Key: Controls plants, including for offensive purposes. This Key was redesigned and renamed the Plant Key for the Netflix series.^[11][12]
• Unnamed Riffel Key (unofficial name):^[12] A key created by Hans Riffel, the last person to use whispering iron before Tyler. The key is to the front door of Keyhouse Manor and implements the Riffel Rule, where no one who enters the front door of the house as an adult can directly see the power of the keys. People who age into adulthood will also begin to lose their conscious memories of the keys and their magic. Shown in the Netflix Series as the Memory Key, resembling a third eye with a keyhole for a pupil.^[13] The Memory Key also bestows the user with the ability to remember magic in adulthood if inserted into their clavicle.
• 2" Key: Shrinks the bearer down to two inches tall.

These keys have not made an appearance in the official comics but appear in merchandise, promotional tie-ins, and/or non-canon materials. They may have also appeared in concept art. Regardless, their purpose or abilities are unknown.

• Ankh Key
• Audible Key
• Biblio Key
• Compass Key
• Freemason Key
• Illuminati Key
• Jetpack Key
• Phoenix Key
• Scepter Key
• Snow Angel Key
• Toy Key
• Trident Key
• Yin-Yang Key

These are locks that are seen in the art that could hint at the existence of potential Keys. Names are not official.

• Cat Key: (Lock seen in Small World). A lock can be seen on the collar worn by Jean and Mary Locke's pet cat, Tiberius.
• Gauntlet Key: (Lock seen in Keys To The Kingdom #3) A gauntlet with a lock on it can be seen in the Harlequin Wardrobe when it is first opened by Bode.
• Keys to Omega Doors #1-#10: (Locks seen in Crown of Shadow #2: "In the Cave" & Clockworks #4: "The Whispering Iron"). While exploring the Drowning Caves, Kinsey Locke and her friends encounter an Omega Door marked with a #1 that they cannot open. This is shown to be a door separate from the Black Door, as the Black Door is deeper in the caves and is marked with a #11. This door reappears in a flashback to Rendell Locke and the Tamers of the Tempest on their way to the Black Door. Omega Doors marked with a #5 and #3 are also seen. This implies that there are at least 10 Omega Doors (not counting #11) in the caves, which may have their own Keys. It is unknown if the Omega Key has anything to do with these doors.
• Penny-farthing Key: (Lock seen in Golden Age 9: "Hell & Gone #2"). One of the items in the Harlequin Wardrobe in 1927 was a Penny-farthing bicycle with Keys as its wheel spokes and a lock on its handle.
• Radio Key: (Lock seen in Dog Days). A keyhole shape can be seen on the old-fashioned radio that the two sons of Mary Locke listen to with their dog.
• Stained Glass Key: (Lock seen in Omega 2). Assuming the keyhole on the Glass Ceiling is an actual keyhole and not just an image. Much like how the keyhole for the Giant Key was also a glass window.

These keys were designed as merchandise and are based on several famous novels and fairy tales. They were created as a limited series by Skelton Crew.^[14] Skelton Crew is solely responsible for making all purchasable replicas of Locke & Key keys.

At the 2019 San Diego Comic-Con, Joe Hill confirmed that a new Locke & Key series called World War Key was in the works.^[38] This storyline as Hill puts it is "about the idea that the past is never gone... and I think a lot of ghost stories are about ways the past keep bleeding through to the present. We'll visit the Revolutionary War, Civil War, and World War II to show how those past events have had lingering effects on our heroes today."^[38] As of 2019, the series is expected to run thirty-seven issues across six books (not including The Golden Age).^[39] World War Key is designed to be both a prequel and a sequel to the original run of Locke & Key.^[40]

A series of short stories set in the past.^[41] In his newsletter, Joe Hill referred to the book as "World War Key 0: The Golden Age".^[42]

Locke & Key: …In Pale Battalions Go… will be a three-issue story that leads into World War Key, set at the beginning of the 20th century and will feature characters from "Small World" and "Open the Moon".^[43] It will also lead into the Locke & Key/Sandman Universe crossover comic.^[42] On February 21, 2020, IDW announced via their Twitter^[44] that Locke & Key would be crossing over with DC Comics's Sandman Universe. The story, Hell & Gone, will center around DC's Key to Hell from The Sandman: Season of Mists. Hell & Gone will wrap up The Golden Age arc.^[45]

According to Joe Hill, ...In Pale Battalions Go... was originally supposed to be just two issues, but he quickly realized that it wasn't enough to tell the full story, so it was increased to three.^[46]

Joe Hill has stated that the chronological order of the Golden Age chapters is as follows:^[62][63]

1. Small World
2. Open the Moon
3. Face the Music
4. ...In Pale Battalions Go...#1
5. ...In Pale Battalions Go...#2
6. ...In Pale Battalions Go...#3
7. Hell & Gone #1
8. Hell & Gone #2

The first arc of World War Key. Joe Hill stated in an interview that Revolution "takes place during the Revolutionary War and it's about how the magical keys won the Revolutionary War."^[64]

The second arc of World War Key, according to Joe Hill. He described the plot: "leaps forward to the modern-day, [where] we visit some favorite characters from the Locke & Key series, and we see how they're doing. And we all see the events of the Revolutionary War staining through into the present."^[64]

Many fans believed that "GRINDHOUSE" and "DOG DAYS" were a part of the Golden Age arc until Joe Hill stated via Twitter that they are at the moment their own standalone stories that are not a part of any arc.^[66]

On November 11, 2014, the first six volumes were collected as a slipcase set of paperbacks.

Locke & Key was also collected in three hardcover books with all-new cover art and design by Gabriel Rodriguez.

• Locke & Key Master Edition Volume 1 (May 19, 2015). Collects the first two arcs, Welcome to Lovecraft and Head Games.
• Locke & Key Master Edition Volume 2 (March 22, 2016). Collects the third and fourth arcs, Crown of Shadows and Keys to the Kingdom.

All six arcs (Welcome to Lovecraft, Head Games, Crown of Shadows, Keys to the Kingdom, Clockworks, and Alpha & Omega) of the main story are published in one compendium edition, featuring new front and back cover art by Gabriel Rodriguez. The compendium had an original release date of October 2020,^[75] but it was delayed and eventually published July 20, 2021.^[76]

On November 11, 2007, Subterranean Press announced a pre-order for a hand-numbered, signed, limited edition of the six-issue run of Welcome To Lovecraft. This edition consisted of 250 numbered copies and 26 lettered copies, both of which sold out within 24 hours of being announced.^[77][78] This edition was a hardcover release in a specially designed and illustrated slipcase, and featured exclusive dust jacket art by Vincent Chong and reprinted all 250 pages of Joe Hill's script in addition to the actual comic work.^[79]

This was followed by the publication of Head Games, which was also limited to 250 hand-numbered and signed copies as well as 26 lettered copies.^[80] The third volume, Crown of Shadows, is available for preorder, and like the previous editions is signed and numbered with the same limitations and also comes with an illustrated slipcase.^[81] Cloth-bound trade editions limited to 1000 copies (unsigned, unnumbered, and without the slipcase) were also released. Trade editions for the first two volumes are sold out.
