Keycard

A keycard is a device used by the Simpsons in The Simpsons Game 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.
