About All CS2 Keys
What keys are for
A key unlocks a sealed weapon case, letting you open it for a chance at the skins and rare special items inside. Each key is tied to a specific case and won't open others. Without a key, a case just sits sealed in your inventory.
One key per case
Most cases have their own matching key, so the key you need depends on the case you want to open. Some older keys opened several early cases, but the modern rule is one key per case. Each key page names the case it unlocks.
Why key prices vary
Key prices track supply and demand: keys for popular or active cases stay in steady circulation, while keys for retired cases can command more. Because keys are consumed on use, there's constant fresh demand from openers. Each key page shows its own live price.
Opening vs. buying the skin
Opening a case is a gamble weighted toward the common tiers, so many traders skip the key and buy the finish they want outright. Others hold keys expecting demand to hold up. Whichever route you prefer, unused keys keep their value well.
