I posted this on a previous FOB programming thread...
For $120, you can program your FOB's with this:
www.obd2tool.com
The one I purchased (not from the source above) came with seven DVD's that included all Hyundai models up to 2017. I don't see those listed with the unit above but there looks to be a thumb drive with this package that may include all models.
After a modest learning curve of the entire software program, I programmed a second FOB on the first try.
With that tool you can also diagnosis pretty much any issues your car comes up with.
AFAIK, this is the same tool Hyundai dealers used in their service departments up through 2017.
