A keycard is a device used by the Simpsons to gain access to The Creator's Mansion so that they can get their creator to stop torturing them by putting them into awful second-rate videogames. Each of the keycards are found in the four videogame worlds that exist in the Game Engine: Medal of Homer, Grand Theft Scratchy, NeverQuest, and Big Super Happy Fun Fun Game. The Comic Book Guy humorously berates the player by saying that a keycard is basically a key.
