Every CS2 and CS:GO key, split by what it opens. Case keys unlock weapon cases; capsule keys unlock the older sticker capsules. Valve stopped selling keys for pre-2019 cases, so those "untradable-era" keys now trade as collectibles in their own right and cost far more than the $2.49 store key. Check which key a case takes before you buy — keys are not interchangeable.
A key only opens the container family it was made for. Modern cases all take the universal CS:GO Case Key sold in-game; older cases from before the unification each took their own named key, and the sticker capsules of that era took capsule keys. Check the container’s own page for the key it accepts before buying — a mismatched key cannot be refunded into a working one.
In October 2019 Valve made all newly purchased keys untradable, which froze the tradable supply at whatever existed on that date. Those pre-2019 keys can still be sold, so they trade well above the in-game store price and behave like collectibles rather than consumables. A key bought from the in-game store today will open a case perfectly well but can never be traded or sold.
