Certain locks require two or more people to unlock them simultaneously. The idea is that even if someone malicious got hold of one key, they'd still need to get hold of the second key. And even if they managed to do that, they'd still need to be able to turn all the keys at once, which are usually placed too far apart for one person to do so on their own. Maybe it's the keys to the world's destruction or the kingdom's treasure, but whatever it is, it's so important that you know it must be good... or really bad. Common in military settings and very much Truth in Television with Nuclear Weapons. An implementation of the more general military concept of "Two Person Control" (TPC). A variation seen in video games, especially ones with co-op play, is a stock puzzle that requires two characters to activate triggers in different places at the same time to complete an objective. May sometimes be played for laughs, where the thing being protected by the two keyed lock turns out to be something mundane, or even silly. Not to be confused with Double Unlock, which is about enabling new game features. |

Ōkamiden being based around partners has a plenty of these throughout the game where Chibi and his partner must stand on pressure pads to unlock doors or make bridges appear. One notable example has a two-buttoned lock which is also a trap forcing Chibi to play through half the dungeon himself to gain the key to free his friend. | |

K-19: The Widowmaker twice sees the crew go through their missile launch procedures.* Once during a dockside exercise, once when launching an unarmed test missile. Three keys, each held by a different officer, must be inserted in a control panel. Additionally, authorization from Moscow must be obtained via automated radio link; this procedure requires a disk kept locked in a safe, which is opened with yet a fourth key.# However, this key is held by the submarine's captain, who also holds one of the three launch keys. | |

Devil May Cry 4: A gate in Mission 11 requires the pressure plates on both sides to be stepped on so that it will open. Nero can just easily snatch the nearby Scarecrow on the other side to get past this. In the Special Edition, the gate is already open when playing as Lady or Vergil because they lack the necessary ability to pull in other enemies. | |

The Lord Darcy story "A Case of Identity" had a two key system for a vault containing the Marquis' official regalia. The door had eight keyholes and two keys. Each man with a key knew which keyhole to use his key in, but not which keyhole the other key went into. Improper timing, or turning a key in the wrong hole, would set off the alarm. The keyholes were usually covered with ornamental doors; when opened, they acted as visual shields so that neither man could see which keyhole the other picked. | |

Rare example not involving nukes: in an episode of Alias set in a Romanian mental hospital, the door to get out is double-keyed, one lock on the wall to either side of a wide maintenance door, too wide for one person to turn both keys with their hands. Sydney deals with this by acrobatically turning the other one with her foot. | |

In the second V (1983) miniseries, the Visitors intend to deploy their mothership as a nuclear bomb as a last resort in case their troops can't hold on to Earth. John and Diana both take one of the arming device's two keys. John is willing to concede defeat and just retreat, but a spiteful Diana wants to kill off all of humanity because they defeated her. She orders John to hand over his key at gunpoint, and kills him when he voices his disgust. | |

Sonic The Hedgehog: Used in Sonic Chronicles: The Dark Brotherhood when you had puzzles where four characters had to stand in certain spots to unlock doors. This is also a common type of puzzle in Sonic Heroes, where all three teammates have to stand on switches at the same time to activate a door or gimmick. While at the start these puzzles boil down to running through a line of switches in Power formation, later stages have the switches located in completely different corners of an area, resulting in a hybrid Escort Mission and No-Gear Level where you have to leave your teammates behind at switches as you travel to the next while making sure said teammates remain safe. |

The Simpsons: In "Hello Gutter, Hello Fadder", two keys were required to be turned simultaneously to drop the "perfect 300 game" balloon at the bowling alley. In "HOMЯ", When Homer goes to the bank to withdraw his family's life savings, he's informed that the money cannot be withdrawn unless both he and Marge agree to it. He goes to the other side of a nearby plant to pretend he's talking Marge into agreeing and then he forges her signature. He also pretends Lisa is there asking for a bonbon. In Season 29's "Gone Boy", Bart stumbles into an abandoned missile silo, and after the Springfield police call off the search, Sideshow Bob hears a news bulletin that Bart is reported to be dead, only for Marge to confirm that he's still alive. After Milhouse leaves the Simpson house, Bob asks Milhouse to lead Bob to Bart's whereabouts in the missile silo. Bob ties Bart and Milhouse to the missile, which requires a two-key setup to ignite, and after stretching his body, he manages to ignite the missile, only to untie Bart and Milhouse from the missile, which lands near the sculptures in the town plaza. |

The 2023 film Last Sentinel has the two key version for a Doomsday Device, but it's useless as one man can still set off the device himself, while holding down a Dead Man Switch that prevents anyone from rushing him.

Atop the Fourth Wall uses the exact self-destruct code from Star Trek III in the Cold Open for his review of... the comic adaptation of Star Trek III in order to prevent Lord Vyce from taking his ship back. Vyce manages to stop the sequence before the ship blows up. Possibly unique in that one of the people who confirms the code is the ship's AI. Linkara makes it clear that he's not asking her to help kill herself, though, as she can transfer her consciousness off the ship. | |

Used in NCIS: Los Angeles when the team has to access a dead man's safe-deposit box, thinking that it contains a little black book of highly classified and potentially damaging secrets. Once they've found the dead man's key, they still have to send in Sam Hanna as his attorney. In another episode three launch officers stationed in nuclear missile silos are revealed to be moles for a radical organization. Two of them end up stationed at the same silo but a failsafe prevents them from launching their missile without an authorization from the President. However, the system has an override that can be activated by the two launch officers of another silo. One of those people is also a mole so he kills his partner and then gets around the two key lock by using a mechanical device that turns both keys at the same time. |

A few 'double-button security locks' show up in Sly 3: Honor Among Thieves. The timing window seems to give some margin of error. Notably, while there are many Two Keyed (and more commonly three, five, seven, or whatever-keyed) locks, these are clustered on the console as individual padlocks. Still, you do have to retrieve all the keys to open it. | |

Predictably, one of them gets greedy and murders the other two for their keys. After hunting him down and killing him, you get all three keys from his corpse and, thus, their loot as your reward. | |

Neon Genesis Evangelion: In episode 13, an Angel infiltrates NERV's computer system and Gendo tries to be Genre Savvy. Then a few minutes later, Maya and Ritsuko do this to hack into the Angel through Casper while Casper is being hacked by the Angel in turn. They enter the final command simultaneously and it works, killing the Angel and disarming the MAGI's self-destruct sequence a single second before it could blow the entire base to kingdom come. In fact, this is how the MAGI self-destruct works: the three cores vote among themselves. Starting or cancelling the sequence requires unanimity of all three; cheating is impossible since any attempts at one core hacking another are immediately discovered. If two disagree and the third is undecided, they'll ask the human crew. |

In My Little Pony: Equestria Girls – Forgotten Friendship, Celestia and Luna open the Bookcase Passage by pulling on a pair of books. Each one uses her own telekinesis to move the book with her respective cutie mark on the spine. Since it should be trivially easy for either of them to do both at the same time, this hints that there is a security system requiring the two alicorns to work in tandem to get access to the restricted section of the library. | |

Mario Party: Mario Party 5: In the minigame ID UFO, two pairs of characters have to press the UFO icons that match the ones shown in front of them. The caveat is that, for each team, the two correct icons have to be pressed at the same time (each by one character), and doing so grants a point to that team while replacing all present UFOs with the next batch. Whichever team manages to score three points will win; but if neither succeeds at that after 60 seconds, the minigame ends in a tie. Mario Party DS: In the minigame Cube Crushers, two teams of characters are navigating through a maze filled with breakable ice cubes, and at the end of each room there are two switches that open the door that leads to the next part. Each team has to punch the ice cubes to break them (they must be careful not to break certain cubes marked with a question mark, as they may end up freezing for a short time; other blocks have a Starman that helps them break stronger blocks, though) and reach the switches, which have to be punched at the same time (each switch is located in a side of the door, so it's required that the two characters approach them separately) so the door to the next room opens. A total of three rooms awaits for each team, and in all cases the door has to be opened the same way. The first team to reach the exit wins. |

James Bond: GoldenEye had this for the titular weapon as well, defeated by simply having two villains working together. Interestingly, this was replicated in the secret underground base as well. No Time to Die: SPECTRE raids a secret MI6 laboratory and demands access to one of the biovaults, which requires two scientists. The moment the two are identified, the others are shot dead, then when the weapon they are after has been removed, one of the scientists is killed and the other taken with them. |

This is also a common type of puzzle in Sonic Heroes, where all three teammates have to stand on switches at the same time to activate a door or gimmick. While at the start these puzzles boil down to running through a line of switches in Power formation, later stages have the switches located in completely different corners of an area, resulting in a hybrid Escort Mission and No-Gear Level where you have to leave your teammates behind at switches as you travel to the next while making sure said teammates remain safe. | |

In Hostile Waters, launching the K-219's missiles requires two keys, one held by Captain Britanov and the other held by Security Officer Pshenishny. The launch procedure is not shown, but the security surrounding the keys is - each key is kept locked in a safe in its holder's cabin, with the safes requiring both a second key and a combination to open. The two key holders are also required to inspect each other's keys periodically, verifying in the presence of another officer that they are "in good order and secure." | |

In Dragon Age: Origins, there are two such locks that the Mage Warden must overcome. The first requires a password passed down through the Chantry followed by a spell by a mage that has passed the Harrowing, the second literally requires two keys, one held by First Enchanter Irving, and the other by Knight Commander Gregor. The keys are needed because the second door has Anti-Magic properties preventing the Warden from just blasting through it. | |

Robot Odyssey has a progressive series of these, starting with having to coordinate two robots to complete a task, to the culmination of the fourth level requiring all four robots to separate operate their switches to free a fifth robot. Then, in the fifth level, those five robots need to work together in programmed coordination to solve the final puzzles. | |

Crimson Tide: Two keys needed to unlock the missile launch controls. The XO refuses the captain's orders to unlock the controls because they lost communications before the launch order was confirmed as protocol demands. Mutiny ensues. One might notice that this is exactly why there are two keys. The captain was in fact acting on legitimate launch orders, and the XO was refusing those orders due to the possibility they had received orders to cancel the launch. The real villains of the film were the (unseen) President and Secretary of Defense, who issued nuclear launch orders with the intention of rescinding them if the situation changed. There are no take-backs in thermonuclear warfare. Aside from the captain and XO having their own arming keys, the captain's safe has additional keys that needed to be passed out to other crew members during launch preparations. The missile launching switch itself was also located in the Missile Control Compartment, behind a multi-door safe; only the weapons officer (played by Viggo Mortensen) had the combinations to the locks. In addition, when the launch order comes in, two officers are required to authenticate it. One reads a random series of letters printed on the order while the other one reads a series of letters from an authenticator kept aboard ship. If both sequences match, the order is authentic. |

The Cave has several puzzles require characters to pull switches/stand on pressure pads to allow other characters to past. Also a literal three-keyed-lock is in the scientist level. This is in fact a central theme of the plot: the parties exploring The Cave are complete strangers with nothing in common save that they all have goals they can't seem to achieve, and this place makes those goals achievable - but not without the assistance of said strangers. This trope is thus pervasively used (both out-of-game by the designers and in-game by The Cave itself) to turn What You Are in the Dark into a group experience. | |

Putting this trope into effect in Stargate SG-1 could almost have been considered a plot thread of its own during the first two seasons or so. In the movie and until the events of the pilot, the SGC had a hair-trigger on the self-destruct button and the Gate's iris, because the primary priority was keeping everything alien out. In the show, though, they start bringing stuff back for study and all kinds of other reasons, and of course, it's stuff they don't fully understand that's often hostile. A Two-Keyed Lock is needed to stop Puppeteer Parasite, a handprint scanner is needed to stop cloaked aliens, and so on. | |

Resident Evil: Oddly enough, only two "puzzles" in Resident Evil 4 need Leon and Ashley to do this. However Resident Evil 5 has loads of these to prevent you from leaving your partner behind. Resident Evil 0, considering its focus on the partner system, also had a few puzzles like this, including one literal two-keyed lock right at the end. Resident Evil 6 has random doors all over the place that require two people to hold down buttons on either side of the frame for them to open. Nothing valuable is behind them, they're just another way to make sure you don't leave your partner behind. Resident Evil – Code: Veronica has one such lock to the weapon used to defeat the Final Boss. Chris and Claire activate it in a cutscene before the final battle. |

The Legend of Zelda: The Legend of Zelda: Majora's Mask has plenty of these in the Stone Tower, and in order to work them you need the Elegy of Emptiness, which creates a statue duplicate of your form, and the Zora and Goron masks (Deku Link's statue is too light to be used for switch pressing). The Legend of Zelda: Four Swords: There are a lot of puzzles which include the "four buttons, each of them only triggers if a person is standing on it"-factor. In some of the games this is subverted by "one player controls four characters". At some places this is required to move on, at others it's just "drop a lot of loot"! The Legend of Zelda: Spirit Tracks: There's a good number of two-keyed puzzles in the game. Sometimes using a block or the assistance of lovely Princess Zelda (as a Phantom) to push one, or hitting a series of switches with the boomerang. |

The Cyclops system in Mobile Suit Gundam SEED was so inhumane (and probably expensive, considering that it was one-shot only) that it required at least five top Earth Alliance generals' keys to turn on. This was reduced to only two in the anime, and the system was set up so that it was possible to have one person to turn both keys as long as he had them. The keys were kept on two separate generals, however. | |

Star Trek: One can actually see this decay in the franchise. In the days of the original series, voice-print match and codes from three senior officers are necessary to activate the auto-destruct sequence. In the days of TNG and DS9, it only takes two with biometric hand scans, and requires both to disable it. By the time of Voyager, Janeway could apparently destroy the entire ship on a whim. Played with in the episode "Cathexis". An alien consciousness is floating around Voyager, possessing various people long enough for them to enter various commands in their computer, then moving on. At one point Janeway considers dividing the command codes between herself and the security chief, as the alien can only possess one person at a time. This actually becomes a plot point in "11001001". The Bynars load the Enterprise's main computer with all the data from their home planet. In order to download it back into the planet's mainframe, a passcode needs to be entered. However, since the Bynars always operate in pairs the passcode has to be entered at two separate terminals simultaneously. The Xindi planet killer required access codes from any three of the five members of the Council in order to fire. This would've been a useful feature when three of Council races back out. Unfortunately, the Reptilians and Insectoids abduct Hoshi and force her to crack a third code. By the time the Insectoids realize they've been played, they've already supplied their code and as such aren't needed anymore. Interestingly, while arming the ship requires three codes, launching it can apparently be done with two. In the TNG episode "Interface", it's explained that it requires two senior officers' authorizations to deactivate the holodeck's safety protocols (though some subsequent TNG-era stories ignored this detail, e.g. Star Trek: First Contact has Picard disengaging the protocols by himself). |

RuneScape: The Dungeoneering skill has two variants on this, in the lever room and follow-the-statue-leaders emote rooms. Getting to the king dagganoths requires two people (or one person and a pet rock) to get past any of the three entrances to the monsters, then three people (each having gone down a different path) to open the door to the kings' lair. The rune thrownaxe was later introduced to circumvent it, as its special attack lets it ricochet off of all three ends. |

Chip's Challenge: A unique version appears in the 121st level, Perfect Match. There's a meandering corridor from whence cloned fireballs are moving to die in a moat of water. Right in front of the clone machine is a toggle door that opens and closes when the level's green buttons are being pressed. Ideally, the door should be closed so the corridor clears up and Chip can reach the exit, but in the central area of the level there are two paths where fireballs move, and each path happens to have a green button as well (and they're pressed whenever Chip or a mook steps onto them). The trope comes into play when Chip makes it so those two buttons are pressed at the same time, canceling out the toggle command and leaving the clone machine's door in its current state (open or closed); this is easier said than done, because it requires pushing a block to kill any surplus fireballs in one of the routes (the other cannot be manipulated), and any mistake will require him to clone new fireballs in that route to recalibrate. Chip can then press a green button in his area in case the toggle door remains open (after the fireballs' pressing match is done) in order to close it, allowing him to finally reach the exit. | |

In Yu-Gi-Oh! GX, Duel Academy Island is the home of the three Sacred Beasts (essentially evil versions of the Egyptian God Cards), which are sealed away beneath the academy. Unlocking them requires seven keys which are being targeted by the Shadow Riders; to protect the keys, Chancellor Shepard entrusts them to Jaden Yuki and his friends. | |

In Freeman's Mind, Gordon accidentally launches what he believes to be a missile (it's actually a satellite delivery rocket, but he hadn't been paying attention to the security guard who told him about it) and afterward mentions that he would have expected one of these instead of just the Big Red Button he pressed. Even for a satellite delivery rocket, and even considering he was resuming an aborted launch, yeah, you'd think the procedure would be at least a little more complex. | |

Steel Rain. After the ruler of North Korea is wounded in a coup, what looks like a smart watch is removed from his wrist but when South Korean intelligence try to examine the watch they find it's heavily encoded. Meanwhile the coup leader is trying to activate North Korea's nuclear arsenal. He's handed the code generator, but is told there's a second code generator that their Great Leader always carried with him. So he has military hackers break the codes of the individual nukes and is able to launch one of them that way. However the protagonist pretends he's stolen the watch and brings it back to him; it's been replaced with a Tracking Device enabling an airstrike to be called in on the coup leader's secret bunker. | |

Oddworld - Abe's Exoddus has a lot of these. Abe can turn one wheel, but there's often more than one required to unlock a door/move a platform/whatever, so you need to bring other Mudokons along and order them to turn the wheels. The timing's fairly forgiving, so assembling the Mudokons is usually the main problem... with one exception, where it's two levers instead of wheels. | |

Skies of Arcadia has a whole dungeon focused around locks that require two people to stand on panels in different parts of the dungeon. The thing is, neither side knew that they were helping each other get past and they just both happened to be searching for the same treasure at the same time(for a double dose of irony, it was to make enough money to go looking for each other). | |

The nuclear missile locks in The Hunt for Red October had one of these. Although we never see the locks themselves, we see Captain Ramius taking possession of both keys — which, as the doctor points out, sort of defeats the point. The movie plays with the idea that Ramius has gone mad and intends to start WW3, but in the novel this idea is rejected as five officers are needed to carry out a launch. It also stated that in the event of the political officer's death, the captain was supposed to take charge of his key. There were probably other standing orders as to who inherits the other keys in the event of any of the other officers with launch keys dying on a voyage as well. A two key (two combination in the book) system was also used on a safe in the submarine that contained the mission orders and code books. Moreover, while the movie version plays up that Captain Ramius took both launch keys as if he could single-handedly activate the missiles, the locks are intentionally positioned far apart enough in the room that it is physically impossible for one man to turn both keys simultaneously. | |

In Metal Gear Solid, the player must find three card keys to deactivate Metal Gear Rex late in the game. The twist, however, is that the one key Snake obtains is actually all three keys. The key is made of shape memory alloy, so depending on what extreme temperatures Snake subjects the key to, it changes into each of the keys. There's also a two-part code, each part memorized by DARPA chief Donald Anderson and ArmsTech president Kenneth Baker, respectively. The PAL key option is stated to be a backup, as a way to disable Rex once the code has been entered, or to enable it if the code is somehow lost. Snake is led to believe Psycho Mantis extracted Anderson's code, even though it should have been impossible, while Baker gave in to Revolver Ocelot's torture. It turns out Ocelot inadvertently killed Anderson before getting him to break, requiring Decoy Octopus to impersonate him and have Snake figure out the key system so they could activate Rex. |

Final Fantasy: Used as a minigame in Final Fantasy VII, where to open a security door three party members must push three widely separated buttons at the same time, the player only controls Cloud and has to timed their button press with Tifa and Barret's automatic button presses. The Four Shrines in Final Fantasy IX must be activated simultaneously, but the only impact this has on gameplay is forcing you to fight a boss with just two characters; you don't control the rest. Similarly the Fork Tower in Final Fantasy V. The tower will explode if both rewards aren't taken simultaneously, so you're forced to split the party. This isn't an idle threat, either - once one party takes their item, the game switches to the other party, and if you don't grab the item within about a minute you get a Non-Standard Game Over. Final Fantasy XI has the Three Mage Gate, which requires three different classes of mage to stand on panels to open initially, though once you pass the gate, you can obtain a charm that allows you to open the gate yourself. |

In order to advance to the next stage of the game, three coins need to be found and thrown into the fountain in the center of the castle simultaneously. However, the coins are enchanted such that any given person can only hold one coin at a time, so at least three separate people must be working together to advance the Game. | |

In The Sum of All Fears, not a physical lock, but when President Fowler orders a nuclear strike on Iran, he has to get it confirmed by someone else from an approved list. Since both the secretaries of State and Defense are dead, he tries to get CIA Deputy Director Jack Ryan to confirm the order. Ryan refuses, since it's an act of Disproportionate Retribution, using a nuke to kill one man. Turns out to be the right call since Iran wasn't actually behind the nuclear attack at the Super Bowl. | |

However, because both key terminals are not immune to hacking and the timespan needed to activate both locks is rather generous, a single Agent with a DART 6 chip can hack both locks rapidly in succession, completely bypassing the security system. | |

Doctor Who: "Journey's End": The Osterhagen Key, a Self-Destruct Mechanism for the Earth, can only be activated if three out of five stations are manned. "Dinosaurs on a Spaceship" has a manual override for the navigational system that requires two people "of the same gene-chain" to unlock it and pilot the ship. Fortunately any old DNA will do, and not just the DNA of the builders. Averted in "Cold War": the launch control system of a Soviet nuclear submarine allows an Ice Warrior to retarget its missiles and ready them for launch using a single key taken from the executive officer. It is an aversion, since the plot hinges on this being possible, but ultimately we don't get to see if the two-key security actually was compromised. Averted in "The Day of the Doctor", when Kate Stewart is able to order the destruction-by-nuke of the Black Archive by herself. |

The cult is keen on twins, and the idea is that the door will be only unlocked by having one identical twin at each scanner. Caroline needs to get in, but there's only one of her. The solution is to go back in time to the beginning of the game and remove an eye from Caroline's unconscious past self to place next to the other scanner, thus solving the mystery of why Caroline woke up at the beginning with a missing eye. | |

Ratchet & Clank Future: A Crack in Time includes a variation of this. Clank must use his newly-acquired ability to shift time to record multiple copies of himself completing various tasks (such as pressing buttons or activating platforms), usually with the end goal of opening a door at the end of a room. The actions of the copies must be perfectly timed in order for the player controlling the "real" Clank to solve the puzzle; with up to four copies working at once to complete the task, the difficulty can ramp up pretty quickly. | |

Tales of Xillia has a gate that needs to be opened by two switches being charged with mana at the same time. The player is led to believe it'll be a timing puzzle like in Final Fantasy VII, but the whole thing is done automatically via cutscene. The point of it is just to show that Leia isn't very good at channeling mana. | |

In the Andromeda pilot episodes, Dylan gives four people he barely knows positions on his ships - because, apparently, one person cannot launch the Nova Bombs even though one can arbitrarily give out the positions necessary to do so. Pops up again in the last season where a pair of (stupid) gang leaders join forces to shake down the locals. They find a key to open a ship they want. Only at the moment when they both have to enter the keys to get the door open they get greedy and turn on each other. |

Darksiders II has few. Several dungeons has Death commanding up to ghosts which results in many cases of this. Then later in the game Death gains the ability to split his soul into two which generally follows this trope more clearly as you have to control both to perform the same actions at the same time. It also turns out the that the final door in the game requires two keys, and they have to be turned at the same time for the door to open. |

Portal: The games use a few of these in both single-player and co-op. The former involve two buttons that need to be pressed within a short timespan of each other, and thus require having your two portal ends right next to them. (One of these is justified as an actual two-keyed security lock. The rest are just part of the tests.) The latter actually involve both players, and the game has thoughtfully included the ability to initiate a countdown that appears on the other's screen. Subverted in Portal 2, where a timed two-switch interlock to open a blast door is defeated by using the portal gun to cross the entire fifty-foot wide room to hit both switches within the time limit, rendering the safety spacing irrelevant. |

Madam Secretary. A computer glitch makes it look like Russia has launched its nuclear arsenal at the United States. The ABORT signal is sent just as an ICBM technician has turned his launch key, then a Reveal Shot shows the other technician was a fraction slower and his key hasn't been turned yet. | |

Godzilla (2014). A nuclear weapon on the deck of a naval vessel is armed via this trope, which along with the spinning cogs, countdown clock, and the keylocks being about three feet apart is presumably for Rule of Drama rather than realism. | |

Star Wars Legends: In The Truce at Bakura, it is revealed that on Imperial ships the Self-Destruct Mechanism consists of two levers that when pulled together will trigger an immediate reactor overload. While there aren't actual locks, the levers are at opposing sides of the bridge to prevent accidental triggering. Star Wars: Allegiance: Mara Jade's field gear includes a lightsaber hidden inside an innocuous-looking data analysis unit. The unit has three hidden catches which must be tripped simultaneously to open it, only two of which can be reached at once by humanoid beings. Mara uses her hands on those and trips the third telekinetically with the Force. |

In Paperinik New Adventures, Morgan Fairfax had the remote of his earthquake-generating system with two keys, of which he kept one himself and the other was given to Mary Ann Flagstarr, his bodyguard (who didn't know his plan) without telling her what it was, so Paperinik or others couldn't stop him by force but he was still able to access the key in case he found it necessary. Just in case, he still had a very complex set of codes in place, something that got handy when Flagstarr realized Paperinik was telling the truth and our heroes realized the twin necklaces were the needed keys. | |

Mario Party DS: In the minigame Cube Crushers, two teams of characters are navigating through a maze filled with breakable ice cubes, and at the end of each room there are two switches that open the door that leads to the next part. Each team has to punch the ice cubes to break them (they must be careful not to break certain cubes marked with a question mark, as they may end up freezing for a short time; other blocks have a Starman that helps them break stronger blocks, though) and reach the switches, which have to be punched at the same time (each switch is located in a side of the door, so it's required that the two characters approach them separately) so the door to the next room opens. A total of three rooms awaits for each team, and in all cases the door has to be opened the same way. The first team to reach the exit wins. | |

Sunshine has a high-tech version; instead of two keys, to override the Master Computer they need the voice patterns from two different crew members. At one point the computer starts turning the spaceship's heat shield towards the sun because a fire has broken out in their oxygen garden, endangering the ship. Unfortunately the captain is EVA on the heat shield, putting his life in danger. One crewman tries to override the computer. A second refuses to do, because their mission (to save the entire human race) is more important than one man's life. A higher ranking officer then backs up the first. The captain then overrides him in turn. | |
