I got it programmed. Thank you everyone.
The mistake that I made when programmed it was that I did not stand close enough to the front of the car thinking that if the car’s transmitter can send out signal to the garage opener 100 yards away, seating inside the car or stand around the front door should be close enough during the process but Noooo. I literally letting the garage remote touching the front of the car that up close and BAM, headlights flashed indicate signal accepted... after that, programming others were so much quick. Again, thank you
