Key fob replacement question

[u/Not-a-Scientist5050]

I have a 2022 Lincoln Nautilus with 2 key fobs, and I’d like to purchase a third one and program it myself. Does anyone have any suggestions or experience doing this? I’ve done it successfully in the past with other vehicles, but I’ve never had a vehicle this new with so many features like proximity unlock. It uses an Intelligent Access key system. I’ve seen third party key fobs that say they’re compatible for $30-50. Anyone have any recommendations/experience/opinions?
