LOST BATTLEFIELD 2142 CD KEY BUT HAVE ORIGINAL INSTALL CD

Hello,

i recently rebuilt my computer and stumbled apon my battlefield 2142 cd while installing all my games

i have had soldiers on battlefield 2 aswell as 2142. i believe i even purchased the 2142 online download packs with northern strike pack included..

unfortunatly due to moving and not having computer or internet for a while, i have lost my original cd case w/book that has the cd key for my original battlefield cd.

apon searching my email to try and find the digital online purchase( if i did purchase) (which i think i did), i discovered that my email was entirely empty with no way of retrieving my past messages back.

i am able to download battlefield 2 via steam program and that also gives access to the battlefield 2 cd key that was included

i was wondering how i go about installing my 2142 game onto my origin account

maybe a request of my cd key, i will answer all security questions and do whatever process that is needed.

i had experienced characters with stats from may hours of play on each game

but do to recources and the time that has gone by i have lost and forgoten my info

if there is any retrieval method to regain my stats, i would much appreciate it.

also how i go about linking my battlefield 2 on steam to my origin account?

any and all help is much appreciated,
