Keys are small
skeleton keys with round bows, although minor design details vary between games. In gameplay, keys are used to unlock essential paths in the Stages blocked by gates. The keys always come in a set of three and lie scattered around for the player to collect by touching them. Only by collecting all three can their gate be opened.
, the keys have only one tooth and flash in different colors. Each level has three keys scattered around them which are needed to open the gate to the Sonic Labyrinth Goal
Keys can either be found lying around the levels or carried around by enemies, the latter which must be destroyed to make them drop the key. Thirty seconds are added to the timer with each key acquired. Upon taking damage, all collected keys scatter in the immediate vicinity: grab them back quickly or they will warp to their original resting spot in the level. Note that retrieving a lost key does not add time to the countdown.
Sonic the Hedgehog (2006)
, the keys are golden with two small teeth, and have a white star surrounded by a blue and red circle within their bow. Keys are only found in Shadow's version of Sonic the Hedgehog (2006) Kingdom Valley and some of the Hard Mode Action Stages. In this game, they lie scattered around the general area of the gate they unlock, usually inside Cases or behind breakable ice walls. Once all of the keys are collected, their gate will automatically be opened.
