Invalid code - Online Pass

i bought this game for my son, he is also having the invalid or expired code problem, it is the limited edition for the PS3, can we just get a code that works? 

bought game last december 1st, Limited edition for PS3,, online pass code invalid

heres the error message 

"The code you entered may not be correct or may no longer be valid.

Please check your entries."

"The code you entered may not be correct or may no longer be valid.

I bought the game for PS3, NFS: Most Wanted Limited edition.

And the problem is with the online pass.

for more than a month has elapsed since the launch the game and still can not access online play is very embarrassing and leaves EA name wrong especially when page $ 100 for the cd

hello,

i went on to multiplayer and it went to online pass and i typed in my code which was inside the case but it didnt work i did quite sometime but i still didnt work so i did purchase code and that didnt work either so i did the other option to go on playstation store and did the redeem code on there and i didnt work so i you mabye you could  give me another code and i will see i that would work

on wich platform are you playing?

ps3
