Steam Keys

Well I guess this is more of a question/gift if it's possible.... Wasn't really sure where to get the best response so figured I'd post it here... I bough the EA Humble bundle and was just wondering, if I didn't use the steam keys... Then can someone else use those keys even if I'd used the origin keys.... Seems like double copy of the game, but I mean they are separate codes after all so I figure it may be possible? If so then I have the codes from them still and I'll give them out, no since in me just holding on to something if I've already redeemed my version of them. Well thanks for replies, I'll be back on in a few hours to check for responses. Later guys!

So I don't know if it'll work that way or not since no one has actually said anything... So now I'm just going to post the Steam keys anyway since I haven't used them.

So, here they are:


Dead Space:
YIVBH-DJEM5-QAX42

Burnout:
QZL3X-II2LT-5MKN5

Crysis 2:
FMYYQ-FRAA0-FNTNB

MOH:
J0370-IGM66-CMPRF

Mirror's Edge:
NETHA-EGEEM-9IQ94


Just let me know if they actually work for one of you guys or not, if they do, I bought a couple of my friends copies as well and I can get whatever codes they didn't use and post them on here and let the others enjoy the splendor.
