History Main / Lockdown

* During the film ''Film/MenInBlackII'', the [=MIB=] [=HQ=] goes into Code 101 [=Lockdown=].

* In ''VideoGame/TheElderScrollsIIIMorrowind'', each of the ThievesGuild OpenSecret "Guild Halls" is putting a plan in place to defend against attack by the rival [[TheSyndicate Camonna Tong]]. The Balmora Guild Hall tasks you with finding a "Master of Security" to rig the [[LegitimateBusinessmensSocialClub South Wall Cornerclub]] to be able to "lock down" in this fashion should the Tong attack.

** In ''Exit Strategy'' a space station goes into lockdown to prevent Dr. Mensah and Murderbot from escaping. When three [=SecUnits=] turn up to kill them, Murderbot is at least able to convince the port authorities to open the door wide enough to let Dr. Mensah out.

%%* ''Film/TheAndromedaStrain'' (without human input).
* Averted in ''Film/TheBourneSupremacy''. Bourne has just escaped from CIA custody.

* Shown in the opening sequence of ''Film/ColossusTheForbinProject'' when the MasterComputer goes on-line, the idea being that no saboteur or commando unit can get inside. Of course, this causes a problem when the computer decides to TakeOverTheWorld.

* ''Film/ForbiddenPlanet'': To demonstrate that he has nothing to fear, Dr. Morbius activates the protective shutters around his residence. When it turns out he actually needs them, the Id Monster easily forces its way through them, and then an even thick door MadeOfIndestructium.

* ''Film/ANewHope'':
** "Close the blast doors!"
** "Open the blast doors, open the blast doors!"

* ''Fanfic/AbraxasHrodvitnon'': In Chapter 15 of this ''Franchise/{{Godzilla}}'' Franchise/MonsterVerse fanfiction, Castle Bravo is effectively thrown into lockdown when its power and communications are shut down with the Monarch staff trapped inside, due to the Many's actions.

[[caption-width-right:350:"Dad, why does our house have blast shields?"[[note]]I didn't know they have blast shields - the landlord must have installed them![[/note]]]]

* ''Film/Alien40thAnniversaryShorts''. In "Specimen", the female protagonist is wearing headphones so doesn't hear the RedAlert until it's too late, leading to her being TrappedInContainment. She tells her colleague to unlock the door, but the quickest way to do this is to reboot the system by [[CutTheJuice cutting the power]], which also [[DarknessEqualsDeath kills the lights]]. Turns out she's not dealing with some alien molecule, but a Xenomorph facehugger.

* ''Film/ExMachina''. The isolated underground lavatory/house automatically locks all the doors whenever the power gets shut off, to prevent someone getting past the security by knocking out the generator. This becomes plot-relevant.
* ''Film/ForbiddenPlanet''. To demonstrate that he has nothing to fear, Dr Morbius activates the protective shutters around his residence. When it turns out he actually needs them, the ID Monster easily forces its way through them, and then an even thick door MadeOfIndestructium.

* ''Film/NoTimeToDie''. When SPECTRE commandos raid a secret [=MI6=] biolab, the entire place goes into lockdown. The commandos force the elevator doors open and throw a sophisticated bomb down the shaft that blows a hole in the floor to the service tunnels beneath, while also deploying hundreds of tiny magnets to generate a magnetic field that will slow down the commandoes to a safe speed when they jump into the shaft. Who said that James Bond had to have all the fancy gadgets?

%%* ''Film/{{Quarantine}}'' (2008).

* ''Film/WarGames''

* ''Literature/TheHungerGames'': During the bombing of [[spoiler: District 13]] in ''Mockingjay''.

* ''Film/ThePurge'': Ethan Hawke's character works for a company that sells advanced security systems that will essentially put homes on lockdown during the 12 hours of crime. However, it becomes apparent through the course of the film that while the system is strong enough to cause opportunistic criminals to seek easier prey, it won't stop a determined group from breaking in.

* Parodied in a VerySpecialEpisode of ''Series/OneTreeHill'' where Jimmy Edwards shoots up the school. He doesn't understand how Keith is able to enter the school because...
-->Jimmy: '''The school's on [=lockdown=]!!!'''
* ''Series/TheOuterLimits1995'': "Blood Brothers" had a secure medical experiment lab that could be sealed and sterilized with microwaves.

* ''Series/PersonOfInterest''. In "If-Then-Else", Team Machine must infiltrate a server room on Wall Street to stop a financial crash. They realise they've been LuredIntoATrap when Samaritan agents are seen entering the floor, whereupon a security lockdown protocol (designed to protect against a terrorist attack) is activated to trap them inside.

* In the ''Series/{{Supernatural}}'' episode [[Recap/SupernaturalS09E02DevilMayCare "Devil May Care" (S09, Ep02)]], Kevin is locked in the bunker unable to contact anyone or open the door after the sensors detected the falling angels.
* ''Series/{{Torchwood}}'' had one that activated by reading poetry and could be removed by reading the ISBN number of said poetry anthology (ItMakesSenseInContext). Later in ''Children of Earth'', the Hub has a lockdown protocol if it detects a bomb inside or near the hub (it very nearly kills Ianto this way).
* The Lone Gunmen used automatic fire doors in the improvised [=lockdown=] of a pathogen-contaminated corridor when they made their HeroicSacrifice at the end of ''Series/TheXFiles''.

* Some countries have put their population in lockdown in their homes and shut down all non-essential businesses to battle the UsefulNotes/COVID19Pandemic of 2020.

A location is isolated by means of locking every door/window/refrigerator/[[AirVentPassageway air vent]]/other entrance in the area so that no one can get in or out of the building. For the medical cases surrounding this, it is a quarantine. Armed guards may also be posted, depending on whether or not the military is involved.

When this begins, the odds are 99% someone will attempt a IndyHatRoll.

* ''[[Literature/TheMurderbotDiaries''

** In ''Exit Strategy'' a space station goes into lockdown to prevent Dr. Mensah and Murderbot from escaping, on the grounds that he's a rogue [=SecUnit=]. He's able to persuade them to open the door enough to [[ThreeLawsCompliant save his human client]], but Murderbot is still on the wrong side of the door when three hostile [=SecUnits=] turn up.

* This is the SpannerInTheWorks for the murder in ''[[Literature/TheMurderbotDiaries Fugitive Telemetry]]''. The body is dumped far from the murder scene, but the killers failed to anticipate that the entire SpaceStation would be put in lockdown preventing them from making a getaway, because murder is so abnormal on Preservation (as [[CapitalismIsBad opposed to the Corporate Rim]] where the killers come from).

* ''WesternAnimation/CodenameKidsNextDoor'': [[ExactlyWhatItSaysOnTheTin The premise]] of "[[Recap/CodenameKidsNextDoorS3E8BOperationLOCKDOWN Operation: L.O.C.K.D.O.W.N.]]". Treehouse lockdowns are known as a "Code L-62", and Numbuh One ordered it after he was lured out of bed into [[OurVampiresAreDifferent Count]] [[ComedicSpanking Spankulot's]] jail cell and transformed into a Spank-Happy Vampire, then during the lockdown, he went on to spread his vampirism to the others.

* In ''VideoGame/SonicAdventure2'', the titular prison of Prison Island is locked down when Tails gets there. Also, the facility that Dr. Eggman breaks into to retrieve the secret weapon goes into [=lockdown=]. This time, you see a number of doors closing and hear a voice telling people to close them. (In both cases, the doors that don't succumb to you blowing off the locks open anyway just because you destroyed some G.U.N. robots.)

* ''VideoGame/DevilSurvivor'' takes place in the "Tokyo Lockdown", things get complicated and bad very quickly.
* Periodically in ''Franchise/DeadSpace'', the room Isaac is in goes into "quarantine" lockdown. The lockdown ends when he successfully defeats the Necromorphs that find their way in.

* A few times in the original ''VideoGame/DeusEx'', usually at UNATCO HQ. As early as the very first mission, where "base is under [=lockdown=] until the danger's gone, Agent Denton", and later when [[spoiler: JC is captured by [=MJ12=] and has to escape out of UNATCO. Getting the key for the front door from Alex Jacobsen is the only way out.]]
* In ''VideoGame/TheElderScrollsIIIMorrowind'', each of the ThievesGuild OpenSecret "Guild Halls" is putting a plan in place to defend against attack by the rival [[TheSyndicate Camonna Tong]]. The Balmora Guild Hall tasks you with finding a "Master of Security" to rig the [[LegitimateBusinessmensSocialClub South Wall Cornerclub]] to be able to "lock down" in this fashion should the Tong attack.

* The second ''Creator/{{Toonami}}'' AlternateRealityGame, titled ''[=Lockdown=]'', centers around the Absolution being trapped in a DerelictGraveyard, unable to move until [=TOM=] repairs the engines and the [=DOKs=] shut down the TractorBeam that's holding them there.

* In ''Anime/IrresponsibleCaptainTylor'', after Tylor is [[spoiler: kidnapped]], the command takes the opportunity to put the whole crew in quarantine because ([[BlatantLies they claim]]) of the alien virus [[spoiler: the crew were infected with to force him to surrender.]]
* NERV goes into [=lockdown=] in ''[[Anime/NeonGenesisEvangelion End of Evangelion]]''. It...doesn't work.
** Even in ''Anime/RebuildOfEvangelion'' , where the UN and NERV bases get extra funding, Angels still blast through blast doors like a torch to wax paper. Anything built by the hand of man slows Angels down at best.

[[folder:Film]]
* Film/Alien40thAnniversaryShorts. In "Specimen", the female protagonist is wearing headphones so doesn't hear the RedAlert until it's too late, leading to her being TrappedInContainment. She tells her colleague to unlock the door, but the quickest way to do this is to reboot the system by [[CutTheJuice cutting the power]], which also [[DarknessEqualsDeath kills the lights]]. Turns out she's not dealing with some alien molecule, but a Xenomorph facehugger.

* Done in the Literature/AgentPendergast novel ''Literature/TheRelic'', with disastrous results.

* ''Literature/TheHungerGames'': During the bombing of [[spoiler: District 13]] in ''Mockingjay''.
* This is the SpannerInTheWorks for the murder in ''[[Literature/TheMurderbotDiaries Fugitive Telemetry]]''. The body is dumped far from the murder scene, but the killers failed to anticipate that the entire SpaceStation would be put in lockdown preventing them from making a getaway, because murder is so abnormal on Preservation (as [[CapitalismIsBad opposed to the Corporate Rim]] where the killers come from).

* The Lone Gunmen used automatic fire doors in the improvised [=lockdown=] of a pathogen-contaminated corridor when they made their HeroicSacrifice at the end of ''Series/TheXFiles''.

* ''Series/{{Heroes}}'' had a [=lockdown=] in Level 5 to keep the bad dudes from getting out.
* The [=lockdown=] in the hatch in ''Series/{{Lost}}'' seems to shield the residents with blast shield. The previous Dharma Initiative resident used these shields as maps before the arrival of the protagonists.
* ''[[Series/TwentyFour 24]]''. CTU is locked down during the first season.
** CTU is locked down constantly, but it never seems to do any good actually stopping people from breaking in or out!
* ''Series/StargateSG1'' has a [=lockdown=] protocol, including StockFootage of the NORAD blast doors closing (see Real Life).
* ''Series/TheOuterLimits1995'': "Blood Brothers" had a secure medical experiment lab that could be sealed and sterilized with microwaves.
* ''Series/{{Spooks}}'' has done this twice. First with the VX episode "I Spy Apocalypse", and then with the episode with the crazy former spy, and the Princess Di conspiracy theory story.

* ''Series/{{Torchwood}}'' had one that activated by reading poetry and could be removed by reading the ISBN number of said poetry anthology (ItMakesSenseInContext). Later in ''Children of Earth'', the Hub has a lockdown protocol if it detects a bomb inside or near the hub (it very nearly kills Ianto this way).
* ''Franchise/StarTrek'' does this a few times. Notable because they also ''fail'' to do it a few times - when locking down the ship would have caused the episode to be very short.
* Happens in ''Series/{{Oz}}'' (and every other prison drama) when someone gets murdered or the prisoners riot.
* Parodied in a VerySpecialEpisode of ''Series/OneTreeHill'' where Jimmy Edwards shoots up the school. He doesn't understand how Keith is able to enter the school because...
-->Jimmy: '''The school's on [=lockdown=]!!!'''

* Purdey gets trapped inside a high-tech building that goes into [=lockdown=] in ''Series/TheNewAvengers'' episode "Complex".

* In the ''Series/{{Supernatural}}'' episode [[Recap/SupernaturalS09E02DevilMayCare "Devil May Care" (S09, Ep02)]], Kevin is locked in the bunker unable to contact anyone or open the door after the sensors detected the falling angels.
* ''Series/{{Angel}}''. The Wolfram & Hart skyscraper does this as a GodzillaThreshold response to the Beast killing everyone in the building. Steel shutters close over all windows, doors and [[AirVentEscape air vents]] in the skyscraper, and every corpse reincarnates as a bloodthirsty zombie. Of course, as the Beast has NighInvulnerability the only people bothered by this [[TrappedInContainment are our heroes]].
* ''Series/DoctorWho''. In "Planet of Evil", numerous doors seal off various parts of the spaceship from the anti-matter monsters, who just [[IntangibleMan walk right through them]].

* ''Series/PersonOfInterest''. In "If-Then-Else", Team Machine must infiltrate a server room on Wall Street to stop a financial crash. They realise they've been LuredIntoATrap when Samaritan agents are seen entering the floor, whereupon a security lockdown protocol (designed to protect against a terrorist attack) is activated to trap them inside.
* In ''Series/{{Cordon}}'', a deadly new disease comes to Belgium and a whole city district is closed and locked down in an attempt to isolate the contagion. Remade for the USA with the action transferred to Atlanta, Georgia, as ''Series/{{Containment}}''.
* ''Series/BlakesSeven'':
** In "[[Recap/BlakesSevenS2E7Killer Killer]]", a derelict spacecraft is put into lockdown, but the corpse of the pilot revives and attacks the doctor doing the autopsy, causing the others to break quarantine in their attempt to rescue him. They later realise this was planned as the corpse has cybernetic components and a SyntheticPlague sent by an alien race to infect humanity.
** In "[[Recap/BlakesSevenS4E6Headhunter Headhunter]]", [[MasterComputer Orac]] refuses to let Scorpio land or teleport to prevent the MonsterOfTheWeek from escaping. It responds by shutting down life support, so Avon overrides Orac's objects to rescue the crew, with inevitable consequences.
* In ''Series/TheGoodDoctor'', the emergency room, containing several important characters, is put under quarantine due to the outbreak of an airborne disease in the episode of the same name.
* ''Series/TheFortyFourHundred'': In "Lockdown", Tom places the Seattle NTAC offices under lockdown after all of the men in the building (including him) are infected with a HatePlague generated by T.J. Kim.
* Subverted in ''Series/{{Chernobyl}}''. The local emergency committee has the city put into lockdown to prevent the spread of 'misinformation', not to protect the people from radiation which is already being carried beyond the city limits. As a result Pripyat is not evacuated until 36 hours after the disaster, and the upper echelons of the Soviet government (not to mention anyone downwind of the Chernobyl plant) are unaware of the true scale of the disaster and the need to take immediate anti-radiation precautions.

* ''Series/TheBarrier'': Discussed when there is worrying news about the [[ThePlague noravirus]] and Julia mentions Madrid may go into lockdown in response. If that were to happen, there would be supply problems.
