Weapon Case Keys

Weapon Case Keys are items in Counter-Strike 2 used to unlock weapon cases, which contain random weapon skins, knives, or gloves.

Overview

Each weapon case requires a key to open. Keys are purchased directly from the in-game store or the Steam Community Market for approximately $2.49 USD (price varies by region). A single key opens a single case, and both the key and case are consumed in the process.

How to Use

Acquire a weapon case (random drops after matches, or purchase from Market)
Purchase or obtain the corresponding key
Click Open on the case in your inventory
The case opening animation reveals your item
The item is added to your inventory

Key Types

Historically, each case type required a specific key (e.g., Chroma Case Key for Chroma Cases). In CS2, Valve has simplified the system with universal keys for newer cases.

Case Opening Odds

When opening a case, the odds of each rarity tier are:

Rarity	Approximate Odds
Mil-Spec (Blue)	79.92%
Restricted (Purple)	15.98%
Classified (Pink)	3.20%
Covert (Red)	0.64%
Extraordinary (Knife/Gloves)	0.26%

Each item also has a ~10% chance of being StatTrak.

Economics

Opening cases is statistically a losing proposition:

Key cost: ~$2.49
Most common drops (Mil-Spec): Often worth $0.03-$1.00
Average return per case opening is significantly less than the key cost
However, rare drops (knives, gloves, valuable skins) can be worth hundreds to thousands
Case opening is essentially a form of lottery/gambling

Market Dynamics

Keys maintain a relatively stable price (~$2.49) since they are available from Valve
Older cases may cost more on the Market due to discontinued drops
Newer cases drop frequently and may be worth only a few cents
Some cases appreciate significantly when they stop dropping (e.g., Bravo Cases)
