My Norton 360 licence is about to expire. I entered a new product key and it comes up as a new product. How do I use this key to extend my expiring licence and avoid having to do a full remote backup
The only way to use a new product key to extend an existing subscription is to contact Norton Support and ask them to add the time from the new to the old.
