For code redemption issues  like yours please contact a game advisor who can solve your issue.  You can find a GA here:

1 Click on the following link: https://help.ea.com/contact-us
2 Make sure you are flogged in (top right corner)
3 Click on the blue button "Contact a Game Advisor"
4 Enter the name of your game or product (or "Origin" for account-related issues) and click "Find Solutions"
5 Select the type of issue and the platform you play on, and click on "Find Solutions".
6 Click on the blue button "I still need help" if the FAQ articles do not apply to your situation.
7 Select a contact option. Note that you may get different contact options depending on your country.

I recommend that you use the telephone option and the “call me” option so you don't have to stay on hold for a long time (call back feature available to North America only).

Make sure the code is correct. If it still says invalid you will have to contact Amazon as they have sold you a product that doesn't work.

hey said ea will replace the new code I DONT UNDERSTAND WHAT I HAVE TO DO amazon says ea will replace the code ea says amazon will replace the code JUST ADD MY GAME

EA doesn't have to correct any misconduct on the part of an Amazon seller.  EA simply does not support the resale of used games.  Amazon, the coordinating part of the operation, is well aware of that EA policy.
