I redeemed the key while playing through the steam client, and i wnat to redeem the codes their.
You mean the "Deluxe Game Key" and the "Deluxe Promo key"?
If you bought the game in Steam you don't have to redeem the keys, the should already be unlocked after installation.
The keys do not automatically activate in steam they require redemption through other sites so for mass effect 2 to have to go to ea games account online and redeem the codes their or not at all. Redeeming the codes on origin will only apply to origin and you have to buy the game there, does not apply to steam version.
