A key is an item that is used to bypass certain barriers preventing progress beyond them. They can be small enough to be handled by a leader or large enough that they must be handled by Pikmin, and upon collection or use, may unlock doors or special gates or reveal the entrance to the next sublevel, floor, or section of a cave, tower, or dungeon.

Keys are items scattered all over the worlds in Pikmin Adventure. Resembling smaller versions of The Key from Pikmin 2, they allow unlocking locked doors, passing certain gates, and more. Keys are often cleverly hidden to make finding them more difficult.

Lost keys are collectible items appearing in every cave in Pikmin: Sinister Incinerator. They may seem to be a treasure, but these objects have an entirely different function as they reveal the hole to the next sublevel upon collection, like The Key in Pikmin 2's Challenge Mode. A missing hole generally means that a lost key must be collected. When the Research Pod picks it up in its tractor beam, the hole to the next sublevel will appear. However, the lost key will mysteriously vanish as soon as it is collected, so it can not be truly collected and has no monetary value.

The lost key looks identical to The Key, being a somewhat square, golden key. Because lost keys continually vanish upon collection, the leaders may be somehow finding the same key throughout each dungeon. It first appears in the Magenta Den, as part of this first dungeon's purpose is to give a tutorial on lost keys. Finding a lost key becomes extremely irritating late into the story because of its frequent appearances in hard-to-reach places.
