I lost my Guild War CD key. how do i get it back?

Hi Guys,
I lost my Guild War box and the cd key is inside but i already have an account to play guild war. is there anyway i get my cd key? is cd key important as i already have an account? i am planning to buy Guild War faction next month, do i need to have my current guild war CD key to be able to play faction or the faction cd key will do to play?
thanks for the help guys

No, you don't need your CD key since you've already activated your account (your email and password are all that matter).

You could try contacting GW support and see if they'd be willing to find out your key (which you don't need) for you (I doubt they will).

Buy Factions, add the key to your current account under "Manage Access Keys" in the "Edit Options" button/page after you login.

Thanks a lot koneko
so when i bought faction i just add the faction cd key to my current account in manage access key option?
thanks a lot

If you want it back for some reason then like koneko said, you can contact GW support and they could probley get it to you.

But you don't need it, the only time you use it is when you create your first character. I haven't needed it since then for anything.

And yes, just add the key under manage acess keys and you will be fine to play Prophecies and Factions.

ok thanks to u all guys for the answer thats very helpful
