'''Key Doors''', also known as '''Locked Doors''' (or '''locked doors'''), appear in the [[Super Mario (franchise)|''Super Mario'' franchise]] as objects with the appearance of a regular [[Warp Door]] with a keyhole, and they cannot be entered without a [[key]].

==History==
===''Super Mario'' series===
====''Super Mario Bros. 2''====

Key Doors are objects in ''[[Yume Kōjō: Doki Doki Panic]]'' and ''[[Super Mario Bros. 2]]''. They are first encountered in [[World 1-2 (Super Mario Bros. 2)|World 1-2]]. If the player character picks up a key for a Key Door, a [[Phanto]] will chase them. Once a Key Door is unlocked, it disappears, though in remakes, only the keyhole disappears by transforming them into normal swing-open Warp Doors.

====''Super Mario 64'' / ''Super Mario 64 DS''====
[[File:SM64 Key Door.png|thumb|150px|A Key Door in ''Super Mario 64'']]
Key Doors in ''[[Super Mario 64]]'' and ''[[Super Mario 64 DS]]'' are used to open certain doors to new courses. In the remake only, there are also Key Doors that hold [[Mario]], [[Luigi]], [[Wario]], and a secret [[Power Star]] in the [[Princess Peach's room|princess's room]].

====''Super Mario Advance 4: Super Mario Bros. 3''====
[[File:SMA4 Key Door.png|frame|left]]
While Key Doors do not appear in ''[[Super Mario Bros. 3]]'', one can be found in the [[Game Boy Advance]] remake ''[[Super Mario Advance 4: Super Mario Bros. 3]]'', in the [[World-e]]-exclusive level [[Doors o' Plenty]].

====''Super Mario Galaxy''====
[[File:SMG Key Door.png|thumb|left|100px]]
Key Doors appear in the [[Ghostly Galaxy]] in ''[[Super Mario Galaxy]]'', where they automatically open as soon as Mario or Luigi obtains a key. In the case of the mission [[Matter Splatter Mansion]], multiple Key Doors can be unlocked at once with one key.

====''Super Mario Maker'' series====
Key Doors are objects in ''[[Super Mario Maker]]'' as of the version 1.40 update and in the base game of ''[[Super Mario Maker for Nintendo 3DS]]''. They can be produced by shaking a [[Warp Door]] again after being shaken into a [[P Warp Door]]. Key Doors are also objects in ''[[Super Mario Maker 2]]'', with the same role, though as of version 3.0.0 of ''Super Mario Maker 2'', [[Cursed Key]]s can also be used to unlock Key Doors.

====''Super Mario Run''====
[[File:SMRlockeddoor.png|10px|right|frame]] 
Key Doors appear in ''[[Super Mario Run]]'' in the course [[Boohind Lock and Key]]. They can be opened only by using the key found in their room. If the player approaches a Key Door without a key, then the door wobbles in place. Once the player has the key, they act identically to Warp Doors. Key Doors resemble [[Ghost House]] doors from ''[[New Super Mario Bros. U]]'' but with keyholes in the center.

====''Super Mario Bros. Wonder''====
Key Doors are objects in ''[[Super Mario Bros. Wonder]]''. They are based on their appearance in the ''Super Mario Maker'' subseries. Only two Key Doors appear in [[Color-Switch Dungeon]]: one requiring a red heart-shaped key, then another later on requiring a blue spade-shaped key, each indicated by the shape of the door frame and the emblem on the door.

===''Yoshi's Story''===

In ''[[Yoshi's Story]]'', locked doors are found in the [[Lift Castle]], [[Ghost Castle]], and [[Magma Castle]].

In ''[[Mario vs. Donkey Kong]]'' and its [[Mario vs. Donkey Kong (Nintendo Switch)|remake]], locked doors appear in all levels excluding the [[Mini-Mario]] levels and boss battles, and are designated with a giant keyhole on them. In the original game, they were referred to generically as '''doors'''<ref>{{cite|title=''Mario vs. Donkey Kong'' North American Virtual Console digital manual|page=9}}</ref>. The player (or [[Key Mini Mario]] in the Plus levels) must carry a [[Key]] towards the door to reach the next area of the level. In all Plus and [[Expert (world)|Expert]] levels, doors act as the goal instead, with no new areas beyond it.

In the remake, doors are redesigned, with an additional red frame featuring a gold star symbol on top. Doors continue to retain their usual purpose, but the music does not stop and no victory fanfare is played when a player enters one, except in Plus and Expert levels. In multiplayer sessions, a player who is not close to the door at the time of its unlocking will be instantly warped inside of it with similar mechanics to ''[[Super Mario 3D World]]''. Additionally, the door will be chained with a silver lock, bearing a resemblance to locked doors in ''[[Mario vs. Donkey Kong: Mini-Land Mayhem!]]''. This requires obtaining a silver [[flying key]] in the level to unchain the door before the main key can be used on it.

Doors are succeeded by similarly functioning [[Goal Door (Mario vs. Donkey Kong series)|Goal Door]]s throughout the ''[[Mario vs. Donkey Kong (series)|Mario vs. Donkey Kong]]'' series, however most appearances do not always require the use of a key to go through them.
