William Westerlund / August 22, 2025 / 5 min read

If you’ve been playing Team Fortress 2 for a while, one of the things that you might want to learn is how to trade in TF2, including where to buy TF2 keys.

There are plenty of options available for purchasing keys, but the Steam Market is generally considered the easiest and most direct method.

What Are TF2 Keys

TF2 Keys

Team Fortress 2 keys, also known as Mann Co. Supply Crate keys, are essential items in the game. You need one key to open each Mann Co. Supply crate, which contains a variety of cosmetic items, skins, and occasionally, rare items.

The importance of these keys cannot be overstated, as they open the door to potentially valuable items that can enhance your gaming experience or even be traded for significant profit.

How Keys Function in TF2

The practice of buying a key to open a crate or case is quite old and is similar to systems found in games like Counter-Strike. Here’s how it works:

📊

Market Dynamics

The value of items within crates can fluctuate based on demand, rarity, and community trends.

💰

Purchasing

Players buy keys to open crates they have acquired through gameplay or trading.

🎁

Unboxing

Each crate contains random items, and the chances of getting a desirable item can vary greatly.

Rarity Classes and Item Wear Levels

In TF2, the items obtained from crates come in various rarity classes and wear levels, impacting their value and desirability. Here’s a breakdown:

Rarity Classes:

🎒

Civilian Grade

Common items with little to no market value.

🛠️

Freelance Grade

Slightly more valuable items.

⚔️

Mercenary Grade

Items with moderate market demand.

🎖️

Commando Grade

Rare items that are often sought after.

🕵️

Assassin Grade

Highly valued and harder to come by.

👑

Elite Grade

The rarest items, often commanding high prices in the market.

Wear Levels:

Factory New

The best quality, essentially unblemished.

🌟

Minimal Wear

Slight signs of use but still in excellent condition.

🔧

Field-Tested

Noticeable wear but still appealing.

🛡️

Well-Worn

Used, affecting its aesthetic value.

💥

Battle-Scarred

Significant wear and tear, usually the least desirable.

One crucial point to remember when buying TF2 keys and unboxing TF2 crates is that skins in Team Fortress 2 do not degrade through usage. If you unbox a Factory New skin and start using it, it will not lose its value as you use it in-game.
