The Chao Key (チャオキー^[1], Chao Kī^?) is an object that appears in the Sonic the Hedgehog series. It is a type of key needed for accessing Chao World.

Description[]

The Chao Key resembles a normal key, albeit blue and the top resembles a Neutral Chao head, complete with a yellow ball. In the center of the "head" is a small image of a Neutral Chao's face.

Overview[]

In Sonic Adventure 2 and its enhanced port, Sonic Adventure 2: Battle, Chao Keys are crucial to entering Chao World, as the player has to collect one as each character and take it to the end of the Stage to unlock every character to play as in Chao World. Chao Keys can be obtained from Chao Container which are hidden in nearly every Stage. These Containers will keep yielding Chao Keys until the player collects it, where it will remain in the player's possession, even if the character loses a life, or being defeated by the enemy, when the Chao Key doesn't disappear, until the Stage is completed. When collected, a Chao icon will appear in the upper left side of the screen.

Trivia[]

• The only two Stages in the game where Chao Keys cannot be obtained at are the driving stages, Route 101 and Route 280.
