Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
Rank Math does not make use of license keys for the purposes of upgrading to Rank Math PRO. Instead, we’ve made it more secure and easier for you, and you only have to connect with your Rank Math account and confirm your subscription to get Rank Math PRO activated on your website.
To activate the license, first, you should install and activate the PRO plugin and then connect the website to the Rank Math account by going to WordPress dashboard > Rank Math dashboard > Help > Connect
Here is a guide for your reference:

I hope this helps. Looking forward to helping you.
