'''Grandpa''': "...says I'm joking! Haha!\\

* ''Literature/HarryPotter'': Want to get into the Chamber of Secrets? Then you'd better know how to speak Parseltongue! [[spoiler:Apparently, just making the correct noises without knowing the language also works, as Ron did years later.]]

* In one episode of ''WesternAnimation/DextersLaboratory'', the titular laboratory only opens when you use the spoken password "Franchise/StarWars". Any other phrase, such as ''omelette du fromage'', won't work and will only increase the security around the lab [[spoiler:including the self-destruct]].

** In the episode "Jellyfish Hunter", Mr. Krabs used a voice-activated lock on the enclosure with all the jellyfish he had Spongebob capture. However, while telling Spongebob about the lock he says "The door is voice-activated, and will only open if I say 'open'." You can guess what happens next.
** Averted in "Survival of the Idiots" where Spongebob and Patrick are trapped in the hibernating Sandy's wintery tree dome. Patrick takes a deep breath, throws out his arms, and says "[[SimpletonVoice Open Sesame! ... Well, I've done all I can do.]]"

--> '''[[WesternAnimation/SpongeBobSquarePants Patrick:]]''' [[TheStinger Well, I've done all I can do.]]

* Sonic tries this phrase in [[VideoGame/SonicStorybookSeries Sonic and the Secret Rings]] to try and enter Erazor Djinn's FinalBoss room. Given he's in the Arabian Nights, it'd qualify as a GenreSavvy move, but it doesn't work as the door requires the seven [[MacGuffin World Rings]] to open.

* In ''WesternAnimation/TheTransformers'', Dr. Arkeville's secret laboratory hidden within a cliff face only opens when he says this command. [[LampshadeHanging Lampshaded]] by Starscream.

--> '''[[WesternAnimation/SpongebobSquarepants Patrick:]]''' [[TheStinger Well, I've done all I can do.]]

A door or area is secured by a lock that uses a sound to open the lock, including a spoken phrase.

%%* Occurrs in ''Series/{{Charmed|1998}}'', like [[FantasyKitchenSink many other magical tropes]]. %% In which episode?
* In the opening episode of ''Series/{{UFO}}'', Alex Freeman activates the lift to SHADO's ElaborateUndergroundBase by doing a LargeHam recitation from ''Theatre/RomeoAndJuliet'' into a receiver disguised as a humidor case. Once his voiceprint is verified, [[ToTheBatpole the office starts sinking into the ground]].

* ''WesternAnimation/SpongeBobSquarePants':

* ''Series/StarTrekTheOriginalSeries'', episode "The Paradise Syndrome": the sonic key to open the "temple" containing the planet's asteroid deflector happens to sound exactly like Kirk calling the ship, and Scotty answering.

* A ''ComicBook/CaptainAmerica'' story had a prison breakout story where the con attempt to escape using Cap's shield, but they can't open the main door because they are not aware that it only opens when you say "Captain America" to it. A sequel story was created when that feature's obvious security problem was explored when the cons were gathered in front of that door and accidentally opened it when someone said Cap's name.

* Mr. Krabs used a voice-activated lock in one episode of ''WesternAnimation/SpongebobSquarepants'', "Jellyfish Hunter", on the enclosure with all the jellyfish he had Spongebob capture. However, while telling Spongebob about the lock he says "The door is voice-activated, and will only open if I say 'open'." You can guess what happens next.

* The RKO 1955 action-comedy ''Son of Sinbad'' has the wives and daughters of the original Forty Thieves, seeking vengeance for their slaughtered families, living in a cave worked by this means... sort of.
