A large key-shaped weapon. It has the power to unlock any seal or lock (Assuming the wielder of the keyblade was a chosen keyblade wielder). It is said it can bring both peace and chaos. When the keychain attached to it's rear is replaced with another special keychain, the keyblade may change form into a new keyblade. (Still keeping it's unlocking capabilities)
