How to download Sims 3 Expansion Packs without Origin?

Before I had Origin, I had multiple Sim's Expansions and the base game all on my desktop. 
To download it, just put the disk in, and go to the start button (usually in the bottom left corner) and press 'Computer'*. 
Once that loads, there will be a Circle with a color in it, also including the trademark Sim's plumbob. 
Press that until an installation screen shows up. Go through the installation process, and it'll show a screen that tells you to enter a serial code. That is on the inside of the box in a little pamphlet. It's usually on the back. Afterwards, it'll download. When you want to play and you have finished the download, take the expansion disk out and put the base game back in. There you go! You have your new expansion downloaded and ready to play.
If you do end up using Origin's fantastic system (I put ALL my games in it, I love the convenience), simply open the Origin application on your desktop, then take your games from the desktop screen to the "My Games" section of the application. 

*Please note that I do have a PC, so I wouldn't know how to do it with a Mac. My apologies. :c

I redeemed all but one code that wouldn't redeem on Origin. It would redeem on the Sims website though. So I'm confused on how you download it from the Sims website because its not showing up on Origin. Help please! Thanks!

Sorry I got back to you all so late. For the first replier, the problem is that I don't have a disk. It was just a code. For the second replier, I told you, it wouldn't show up on Origin. I tried logging in and out and closing the application and starting it up again. It didn't work.
