Key

Keys are items found in all Croc games.

Silver Keys
Silver Keys will enable Croc to open Cages that contain either a Gobbo Baron Dante has imprisoned, or Red Buttons that manipulate a platform or other part to a level. These keys are most commonly found in Croc: Legend of the Gobbos.

Gold Keys
Gold Keys help Croc open Locked Doors that have big, gold locks on them. A Gobbo or something usually important is what usually hides behind these doors. In some levels, the locked door is actually the only way to advance and complete the level.

Croc 2
Keys are used in certain quests, such as Find the Key! Save the Gobbo!. Their use varies depending on the quest.

Croc Mobile: Jungle Rumble! and Volcanic Panic!
Keys are found in some levels in both games, being used similarly to the console games to save Gobbos in cages. Unlike the console games, all rescued Gobbos in these games are found in cages.

In Pinball
The Key found on the pinball board acts as a wild card of sorts. You can get a prize from it, but you could also end up with a booby prize.
