So Ive followed all the intrusctions to the T and I just cant seem to get my garage door opening feature to work. It says that if I follow the instructions and the light blinks rapidly when I try and use it I have to go to the actual garage door opening motor and press some "learn" button. But mine doesnt have one!!! I dont actually have my own garage door opener, Im living with my dad before i go off to college, and programming my homelink is my only way to get into the house... All our keys say do not duplicate so they cant cut me a key. I HAVE to make this work. Please help.
