How to Activate Norton Internet Security: While Norton Product Key Activation Support and Norton Internet Security products come with valid product keys that can be used to activate your software, other security products (like Norton Security and Norton 360) don’t ship with these codes included. Even if you’ve received one of these products as a gift, your product key should still be available online if you need to re-install or transfer your subscription. Follow these steps to activate any Norton security product using the Norton account you created when you first installed the software.
