Its really easy.. you cant...
Keys are made for you to use not to trade with someone

You can't.

Steam keys can be activated onto a single account. That is all.
They can't be traded through the trading system.

What should I not trade for?
■Trading items/gifts for CD Keys. You cannot add a CD Key into the trade window. CD Keys that are offered can be for a different game, fake, used or region restricted. A common example of this trade is trading items/gifts in return for a promotional CD Key that is never given to you.
