1 Open your Norton program and click on your initials. 2 Hover over "Serial Number" and click "Enter a Key". 3 You can now fill in your product key. After filling in your code click "Next". You may have to log in after that, if so, log in, if not, you're done. TIP: If the "Next" button does not turn yellow check for spelling errors in the product key because this means there's a typo.
