Thanks for the guide! I’ve used the Autel IM508 to add keys to a couple of Toyota models myself. It’s pretty straightforward once you get the hang of it. Just make sure your network connection is stable, and having the master key is crucial. Had a similar process with my 2019 Fortuner and it worked like a charm. Good luck with your key programming!
