Can't Return Key Fob

I ordered this key fob thinking it was the right one for my 2012 Kia Sportage, it isn't, it doesn't contain the chip components on the inside either. The item description says it doesn't, I expected it not to have the programable chip parts. I can't return the item through Amazon because they are a Private Seller, but they don't have any kind of Warranty or Return Policy. Ultimately, I should have checked the item better, but I wish I could return it. They don't list that they don't have any kind of return policy either.
