Hi. I'm Brian and I'll try to help.
How are you trying to redeem the product key? What happens when you try? You don't usually renew a subscription by buying a new product key (which you should not publish in a public forum). If you have a subscription, log into your Microsoft account at https://account.microsoft.com/services and renew it there.
