Key is a type of Rocket League Items that are used to open Crates for valuable randomly chosen rewards. Keys can be bought from the in-game marketplace, as well as, traded with other players. When it comes to buying them from the official store, they come in sets of 1, 5, 10, and 20 with small discounts the more you buy. Keys, once obtained from the Psyonix store, can't be traded for seven days, so if you are looking to get them to trade for Items with other players, you should consider buying them from other players. At the same time, Keys bought from regular players are usually cheaper. 

Keys are currently the official in-game Currency, which determines price of all Items and is the primary mean of exchange in Rocket League (on top of the standard "Barter trade" which is also very common). However, Keys are scheduled for removal on December 3, 2019. They will be replaced with a new Currency called "Credits". This is done because of global trends that are looking to limit gambling in online gaming done via Loot Crates/Boxes etc. which have randomly generated rewards with low odds of getting valuable rewards. Credits will allow players to obtain specific Items from Item Shop or build Items based on Blueprints owned, or purchase Rocket Passes. While we are yet to find out if this is a change for good, Rocket League Keys will always be remembered for having played a big part in Rocket League's history. 

There are two types of Keys in Rocket League which are the standard Keys, and Decryptors. They are used for the same purpose - to open Crates, however, they are obtained from different sources and Decryptors, nor the Items you obtain using them, are tradeable.

Keys can be obtained via the in-game store, purchased/traded with other players, and awarded from Rocket Pass. Est. price in-game: $1.00 Est. price when bought from players: $0.60
Decryptor	Decryptors can be used to open any Crate, however, neither Decryptors or the Items you will be obtained from Crates opened using them, will be tradeable. This is a good alternative for players that don't want to spend real-life money in Items in Rocket League, however, finding rare Titanium White Items from Crates opened with Decryptors can be really frustrating. Also, if you Trade-in Items, if even of them is non-tradeable, the reward will also be non-tradeable. Decryptors can be obtained as rewards from online matches, special events, and Rocket Pass. They can't be traded so we can't give you an estimated price on Decryptors.
