How do i download using a digital origin key

@samozzy93 Open Origin - click Origin in the upper left - click redeem code

@samozzy93 Does the sims 3 game icon appear in Origin? If so hover over the game icon and click the small i. You should see the expansion packs and if the code took PETS should download and install install. Personally I would be leary about buying a Sims code off Ebay because the code can only be used once. If you got a used code you'll have to return to the seller.
