Instructions
Call Electronic Arts at 866-543-5435 between 7 a.m. and 7 p.m. Pacific time. The company operates seven days a week. You need a live adviser to reset your old code.
Listen to the automated menu and follow the instructions to get to a live adviser. The menu changes periodically, so listen to the options even if you've called in the past.
Explain your problem to the EA representative and tell him why you need the code reactivated. Specify that it is a PS3 code as well. EA designed the game to accept each code only once, so the representative may be reluctant to reactivate a code unless you have a good reason for why the code no longer works. The representative can then activate the code remotely, and it will work the next time you enter it into the PS3.
