The Castle Key[1] is an object that appears in Sonic Heroes. They are usual keys with the ability to open the doors inside Mystic Mansion. Team Chaotix's objective in Hang Castle is to find these keys.


The Castle Keys resemble mostly keys for lever-type locks. They have a slightly flattered, green hexagon-shaped bow with what appears to be a half-closed eye in the middle. They also possess a short shaft and two teeth for a head. They are usually found afloat on the ground.


A key fading away after being collected.

The Castle Keys appear exclusively in Team Chaotix's version of Hang Castle where ten of them are hidden in the Stage. The player's objective here is to collect all ten Castle Keys. Upon touching a key, they give off a small "ping" and slowly fade away. Sometimes, they are found inside cages and other times they float in open areas.
