They can be unlocked with keys, which are available for sale in the "Manage Inventory" and "Crate Unlock" menus. Unlocking a crate will reveal a random exclusive item. There is also a chance of acquiring a certified or painted variant of said item.
Each crate has a unique "series" of items. Items in each crate are classified as Rare, Very Rare, Import, Exotic, and Black Market.
Players can obtain keys by purchasing on their specific platform's marketplace in sets of 1, 5, 10, and 20.
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.
Crates drop randomly after completing on-line matches, with one estimate being that a player will receive one crate for every 10 hours played. Although Psyonix initially suggested that crates could only be obtained through Competitive mode, this is not actually the case.
Crates can also be traded with other players.
List of available crates
On May 22, 2017, Psyonix announced that the Champion Crate series would be retired in June, 2017, with other crates set to retire approximately six months after their initial release date.
All four Champion crates were officially retired on July 5, 2017.

Black Market decals are unique in that they are shown in the preview as an Octane Battle-Car partially covered by a purple hexagon-motif fabric. These decals are dubbed "Mystery Universal Decal" in the preview, which means that the Black Market decals are applicable to all Battle-Cars.
