To open a CS2 case, you’ll need a CS2 key. Each key comes with its own price, and understanding the cost is helpful if you’re planning to try your luck with case openings. Here’s a simple breakdown of what a CS2 key costs and where you can get one.
Here’s a quick summary of CS2 key pricing:
- In-game non-tradable CS2 keys cost $2.50 each
- Tradable CS2 keys cost between $8-$16+ depending on rarity and demand
- Older or case-specific keys can exceed $20 on third-party markets
Below are full details for each pricing type.
In-Game Key Price
The standard price for a CS2 key purchased directly in-game is $2.50. These are non-tradable and can only be used by the buyer. You’ll find them available at this fixed rate on the case opening screen.
Tradable Key Prices
Tradable keys are no longer available for purchase through the game, which makes them rarer. These keys were originally bought before Valve restricted trading. Because of their limited supply, their prices range from $8 to $16 depending on the case they unlock and current market demand.
Certain keys tied to discontinued or high-value cases can cost significantly more. On platforms like the Steam Community Market or third-party marketplaces, some CS2 keys sell for $20 or more.
