The Cell Key[1] is an object that appears in Sonic Heroes. They are a set of keys that can unlock Dr. Eggman's prison cell on Final Fortress. Team Chaotix's main objective in Final Fortress is to collect these keys.


The Cell Keys resemble mostly keys for lever-type locks. They have a flat, hexagon-shaped white bow with a red rim and a symbol resembling the Eggman Empire's on it. 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 Cell Keys are found exclusively in Team Chaotix's version of Final Fortress where ten of them can be found hidden in the Stage. In the normal Mission for the Final Fortress, the objective is to collect only five Cell Keys, while in the Stage's Extra Mission, all ten must be collected.

When touching a Cell Key, they will give off a small "ping" and then slowly fade away. In most cases, they are found in cages that the player must unlock, usually by destroying surrounding enemies.
