Redeeming a code on Sims 3: My code is too long?

[sylvarian404]

I've had Sims 3 since it first came out and just recently I lost the disc. I downloaded Origin and created and account and I also have an account on the Sims 3 website. I tried to redeem my code but the website (Sims 3) only provides 4 boxes for my code but my code is longer than 4 boxes, it's 5. I have my manual and I have the code, I even tried putting it on Origin but I found that I had to register it on TheSims3.com first, so I tried but I ran into my issue-- my Sims 3 redeemption code is too long for the website. Do I have to buy a new Sims 3 game?
