I have a stock GT-R. 2011 year of release. After several attempts, I failed to successfully program the garage door opener. I'm having problems at the stage where you have to hold down the home button and the hand controller for 80 seconds until the slow flash turns into a fast flash. The problem here is that the slow flash stopped flashing after about 50 seconds. Nothing else will happen. I'm pretty much lost at the moment. Any help would be greatly appreciated!
Maybe your code didn't fit your car, so there were problems? I've had this happen to me. And Homelink wouldn't pick up the garage door when I approached it. You can contact the support service of the manufacturer of your garage doors. If you don't receive a call, you can call this store https://www.garagedoornation.com to consult about your problem. I order various parts for the garage in this store. They also provide services for installing spare parts for garage doors in case of breakdowns. So they may well help you explain how to reinstall your Homelink or fix the problem. Garagedoornation has contact details on the website.
