The most straightforward way of getting keys in Rocket League is to purchase them from the in-game menu. Purchasing keys directly from the in-game menu supports the developer, and a part of the proceeds go towards funding the Rocket League eSports scene. Keys purchased in-game cannot be traded for 7 days to protect users against fraudulent charges, so keep that in mind.
This is what some of you are here for. Let’s face it, the game doesn’t give one an obvious way of getting keys for free like you might be able to in some F2P mobile games. There are, however, several ways to get Rocket League keys without spending your cold hard cash. They are:
Trade items to other players for keys
Trade crates to other players for keys
Using trade-ups for betters items and trading upgraded items
Trading items from RLCS events for Keys
Trade Items To Other Players for Keys
This is the simplest way. If you have items that other players want, you can trade them for items that you want. There are several places I’m going to recommend for you to go to trade without fear of getting scammed
Trade Crates To Other Players for Keys
If you are not going to use keys to open crates up yourself, this is a good way to get free rocket league keys. Crates drop regularly during online play. When new crates types come out, that is the best time to trade them as they can go for nearly a key a piece or 2 crates for a key. Other crates will fetch a much lower piece.
How to Get Crates (The Rocket League Crate System)
There are 3 ways to get crates in Rocket League:
Play online matches
Trade items or keys to other players for crates
Purchase event-themed crates
Psyonix announced on May 22, 2017 that each different type of crate will be scheduled for retirement roughly six months after their initial release. This means that the retired crates will no longer drop after matches. Consequently, fewer types of crates can be acquired via online matches, increasing the chance for newer crates.
