We don't always have keys in stock. We only get more in stock when other users sell keys to us. This is heavily dependant on the current market situation and key prices.

In key banking we only accept normal Mann Co supply crate keys. This means that we do not accept other keys like : EoTL keys, nice keys, naughty keys, summer keys, etc.. We also do not accept/buy keys that were event keys and turned into normal keys.

However, in item banking we accept some of the alternative keys.

Yes, it does. The current stock limits are 5 basic killstreak kits per weapon, 7 specialized killstreak kits per weapon (one of each color sheen) and 49 professional killstreak kits per weapon (one for each killstreaker per color)

This is a guide on how to use Mann Vs. Machine part banking.

I want to buy some Mann Vs. Machine parts for metal, how do I buy these?

This is the Mann Vs. Machine banking page.

You'll see a list of bots when you click the "Buy Parts" button. Choose a bot to continue.

Here you choose the part(s) you want to buy. I've selected two Battle-Worn Robot Taunt Processors.
You can choose to pay with Metal or your Robo Parts + Metal.
I wanna pay with metal only so I press the "Offer Metal Only" button.

You're now in the queue to buy the Robo-Part(s) you selected. You might be in a queue for a minute or so. 

Now this will pop up. Click the green "Go to trade offer"

You'll now get into a trade. Simply accept the trade if everything is alright.
When the offer is alright and has gone through then the trade will be closed.

You'll now see this. You now have the weapons you wanted. Simply close it by clicking the white X at the top right of the box.

You've now succesfully completed a Mann Vs. Machine Robo Part trade! Congratulations!
It's basically the same with all the other trades, but. You can always go and check those tutorials as well.

This option/feature makes the bot detect the fabricators in your backpack and automatically sends you a trade offer with the parts that you are missing in order to complete it/them.

That's because all of our bots are full, you will have to wait until they have more space in their inventory.

You can check their inventory capacity by going to the about page.

The stock limit is of two units per wear of that skin. This stock limit is global, meaning that if one bot has one unit of said skin with a certain wear and the other bot has the same skin with the same wear, we won't be buying it.

1. Some user gives items to the bot for free, giving them away.
2. Some other user notices that the bot has items in it's backpack and "buys" them (like every other banking).
3. That other user gets the items for free.

That's because all of the metal that is being stored in such bot is used for future item/site refunds or for other situations which is urgently needed.

That's because the items which have been incinerated have quickly been grabbed by other users. Staff does not put items in the incinerator bot by request.
