Is it a smart key or just keyless entry transmitter? I've never programmed a Hyundai keyless, but my Alldata tells me that you would use Hyundai GDS software to program it in. Perhaps someone that has done it before can chime in if an Autel tool has the "Transmitter Code Saving" function available. I have a 2016 Hyundai at my shop that I'll test tomorrow and report back.
