Map Key

The Map Key is a special golden key used in the game Donkey Kong Country Returns. One level in each of the eight worlds in the game contains a locked path which can be seen on the map screen, as a literal lock with a golden chain. A map key is required to unlock the path for the level to be accessible for Donkey Kong and Diddy Kong after they have completed the previous one.

A Map key can be purchased at Cranky Kong's Shop in each world for twenty Banana Coins. Once bought and immediately after exiting the shop, the key will unlock the path that the Kongs aren't able to access after finishing the previous level on the World's map screen. Unlocking the path can also provide a shortcut leading to another level and the world's boss without completing all the levels for each world.
