Keys are items in Rocket League that can be bought from a player's specific platform's marketplace and used to unlock crates. They come in sets of 1, 5, 10, and 20. They can also be traded with other players and are commonly used as "trading money". Xbox however is restricted from trading keys between players.
Keys have a "trade hold" that prevents them from being traded to other players for 7 days from the time of purchase. As such, keys used to obtain items from crates will transfer the remaining "trade hold" time from the key to the item.
