[[File:Symbol - Keyhole.png|right|A Keyhole]]
A {{Nihongo|'''Keyhole'''|鍵穴|Kagiana}} is a gateway in each [[world]] that leads to the [[heart]] of that world. The [[Heartless]] invade worlds and search for their Keyholes. Upon discovering the Keyhole, the Heartless will enter it and eventually devour the world's heart. After a world's heart is consumed, the world crumbles, and fades from existence. It is said that, if the [[Keyblade]] locks a world's Keyhole, it can never be opened again.

==Story==
===''[[Kingdom Hearts Birth by Sleep]]''===
When [[Aqua]] travels to the Throne Room of the [[Land of Departure]] with [[Ventus]]'s comatose [[body]], after being named the only [[Keyblade Master]] successor of [[Eraqus]] and after finding [[Master's Defender|her late Master's Keyblade]], she uses it to access the Land of Departure's Keyhole in order to transform it into [[Castle Oblivion]], and the Throne Room into the [[Chambers of Repose and Waking|Chamber of Waking]], in order to keep Ventus's motionless body safe.

===''{{c|Kingdom Hearts|game}}''===
[[File:The Dark Powers 01 KH.png|thumb|left|Riku sees Destiny Islands' Keyhole appear inside the Secret Cave.]]
The Heartless invaded [[Destiny Islands]], the home of [[Sora]], [[Riku]], and [[Kairi]]. Not only did they attack the islands in search of the Keyhole, but also to find the Keyblade Master and one of the Seven [[Princesses of Heart]], who is Kairi. The islands were eventually destroyed when the Heartless attacked Kairi and managed to get into the Keyhole (located in the Secret Cave). Sora ended up in [[Traverse Town]] by going through a [[Corridor of Darkness]] (which opened during the islands' destruction), while Riku ended up in [[Hollow Bastion]]. Kairi's body was found by [[Maleficent]]. In Traverse Town, Sora learned from [[Leon]] and [[Yuffie]] that the Heartless took over their world by order of Maleficent. Sora, along with [[Donald Duck|Donald]] and [[Goofy]], decide it is their duty to travel from world to world and seal the Keyholes using the Keyblade.

Maleficent and her gang of villains were in the midst of completing an artificial Keyhole in Hollow Bastion by obtaining the seven hearts of the Princesses of Heart. That Keyhole, once completed, would lead them into [[Kingdom Hearts]], the heart of all kingdoms and source for immeasurable power and knowledge. However, without Kairi's heart the Keyhole remained incomplete. Her heart was actually dwelling inside Sora's. Sora eventually released Kairi's heart using the [[Keyblade of heart]], completing the Keyhole. [[Ansem, Seeker of Darkness|Ansem]], who possessed Riku's body, ventured into the Keyhole in order to get to Kingdom Hearts. Sora sealed the Keyhole and then followed Ansem to the [[End of the World]], a place formed from the remains of worlds taken by the Heartless. Deep in the [[darkness]] of that place lay the [[Door to Darkness]], with Kingdom Hearts lying beyond it. There, Sora battled Ansem. Ansem then opened the door so he could obtain the darkness inside Kingdom Hearts, but Sora called out the [[light]] from inside the door and Ansem was destroyed. Sora, Riku and [[Mickey Mouse|King Mickey]] sealed away Kingdom Hearts by locking the Door of Darkness on both sides. All of the destroyed worlds were restored, including Destiny Islands. It is presumed all the restored worlds had their Keyholes sealed automatically and hidden, so they could not be destroyed again.

===''[[Kingdom Hearts Chain of Memories]]''===
Following his final battle with [[Marluxia]], [[Sora]] seals the room where they fought, causing the doors to vanish.

===''[[Kingdom Hearts 358/2 Days]]''===
The term "Keyhole" was only mentioned when [[Roxas]] and [[Xion]] experience a memory of Sora sealing the Keyhole of [[Agrabah]]. Coincidentally, all of the [[Organization XIII Device|devices]] that Xion absorbs power from during her battle with Roxas were planted near the Keyholes of Wonderland, Halloween Town, and Agrabah.

===''[[Kingdom Hearts II]]''===
Instead of sealing the Keyhole of a world, Sora opens the world's [[Gate]], which reveals a new path to a different world. Curiously, though several never-before-seen worlds appeared in ''Kingdom Hearts II'', not one of them had their Keyholes sealed, mainly because after End of the World was destroyed, all worlds went back to what they used to be, and the newer worlds therefore had no reason to be sealed by a Keyblade. Sora did use the Keyblade to seal a Keyhole on [[Pete]]'s door to [[Timeless River]], to unlock the seal on the door blocking himself, Donald, Goofy and [[Auron]] from escaping [[Cerberus]], and to unlock the [[Underdrome]] in order to save [[Megara]].

===''[[Kingdom Hearts coded]]''===
[[File:Keyhole Entrance KHREC.png|thumb|The door Data-Sora uses to enter the worlds' Keyholes.]]
In order to rid each of the worlds within the [[Datascape]] of the [[Bug Blox]] plaguing them, [[Data-Sora]] searches for and enters the Keyhole of each of the data worlds, within which he faces the bosses which are generating bugs. Energy spikes within Keyholes alter Data-Sora's powers, resulting in [[side-scrolling]], [[3D shooting]] and [[Labyrinth]] segments. Data-Sora also uses a Keyhole to enter [[Data-Riku]]'s inner data, where he eliminates the bugs that are corrupting Riku. When Mickey enters the Datascape after the data is reset, he shows Data-Sora a Keyhole that leads them to the digital Castle Oblivion.

===''[[Kingdom Hearts 3D: Dream Drop Distance]]''===
{{main|Sleeping Keyhole}}
As part of their [[Mark of Mastery exam]], [[Yen Sid]] sends Sora and Riku to the [[Sleeping Worlds]] to unlock the seven [[Sleeping Keyhole]]s, and return the worlds to the [[Realm of Light]].

===''[[Kingdom Hearts III]]''===
Sora seals the Keyhole on the door used to banish [[Randall Boggs]] in [[Monstropolis]], causing the door to vanish into nothing, presumably sealing Randall out forever. This seemingly is not the Keyhole of Monstropolis itself, as [[Boo]]'s door still works.

Aqua summons the Keyhole of [[Castle Oblivion]] and unlocks it. This reverts the world back into [[The Land of Departure]] and repairs the damage caused by [[Xehanort]] calling a storm of darkness a decade earlier.

The [[Replica Xehanort]]s use the power of Kingdom Hearts to open various Keyholes to a dark void, trapping Aqua, Ventus, [[Terra]], Riku, Roxas, [[Lea]], and Xion. The Keyholes coalesce into a single large glowing Keyhole, which Sora enters and uses Mickey's light to free the Guardians.

To find Sora and Xehanort, the [[Seven Guardians of Light]] open a Keyhole to [[Scala ad Caelum]].

===''[[Kingdom Hearts III]]''===
In [[Monstropolis]], after the [[Lump of Horror]] is defeated and [[Randall]]’s takeover of Monsters, Inc. is thwarted, [[Sulley]] and [[Mike]] banish him once again through the same repaired doorway he originally passed through. Before Sully can punch out the light like he previously did when Randall was first banished, Sora offers an alternative solution. Using his Keyblade, Sora permanently seals the door, which fades into light completely.

*'''[[Atlantica]]:''' The Keyhole is hidden in Ariel's Grotto. It can only be accessed using a [[Crystal Trident]] or [[King Triton]]'s trident. After defeating [[Ursula]], Triton allowed Sora to lock the Keyhole using the trident to reveal it.
