The Key is a collectable item that first appeared in Pac-Man. It is worth 5,000 points if eaten. In the Pac-Man Championship Edition games, it gives the player 4,000 points. In Pac-Man World, keys are used to free the six friends who got captured by Toc-Man. Also, there is another key known as the Magic Key. It can be obtained after the player has a grand score of 1,000,000 points, and allows Pac-Man to unlock any Fruit Door without needing the corresponding fruit. In Super Pac-Man, there are 15 keys on each level that can be used to open gates, and each one gives 50 points plus an open gate.
- In the Game Boy Color version of Pac-Man, the key's sprite is mirrored in a different direction.
