钥匙

Case keys are functional items in CS2 used to unlock weapon cases, which contain randomised weapon skins and occasionally rare knives or gloves. Each key is tied to a specific case type, for example, the Kilowatt Case Key opens only Kilowatt Cases, so matching the right key to the right crate is essential before you open. Keys are consistently among the most liquid and steadily priced items in the CS2 economy. Because each Major or seasonal update introduces new cases, the key catalogue has grown considerably since CS:GO. Prices sit within a relatively narrow band compared to skins, making keys one of the more predictable items to buy and sell. Some older or discontinued keys from legacy CS:GO cases can trade at a slight premium due to scarcity. SIH gives you a complete, up-to-date listing of every key available in CS2 and from the CS:GO back catalogue. You can instantly compare prices across 28+ marketplaces, Steam Market, Buff163, CSFloat, Skinport, DMarket, CS.Money, and more, refreshed every hour. Whether you need a single key to open a case you already own or want to buy in bulk, checking SIH first saves you the manual tab-switching across multiple sites. The price history charts on each key page help you judge whether current prices represent a dip or are riding a temporary wave. You can also add keys to your inventory tracker to include them in your full portfolio valuation alongside your skins, knives, and stickers. Head to the keys catalogue on SIH, find the key you need, and compare prices now to get the best deal before you open your next case.
