renewing NIS 2014 v 21.7.0.11

Vitsa Home Basic laptop
Windows 7 PC
Windows 8.1 laptop

all currently run Norton Internet Security 2014 v 21.7.0.11
I have no intentions of upgrading any of these machines to Windows 10 at this time
I am down to the last week of my current subscription. I want to stay with Norton Internet Security v 21.7.0.11. I dont want the upgraded Norton Internet Security 2014 v22 or the Norton Security v22

So I assume the logical step is to open the GUI and click on the renew option at the bottom of the windows (where it shows how many subscription days are left) and then follow the prompts?
Do I need a key if I am renewing and paying by credit card for the renewal?
