Crate Keys are an item in Ghost Simulator. They can be used to open any Pet or Board Crate. They are obtained by either completing quests, opening boss crates, or from Daily Rewards. You can also purchase crate keys from the shop for robux. Crate keys obtained for free from boss chests or from quests have the "[Non-Tradable]" tag, meaning you cannot trade them, however the ones purchased with Robux are tradable, and thus rarer. Non-tradable crate keys are used first. Crate Keys cannot be burnt at the Incinerator in the Junkyard.
