I have a 2015 Chevrolet Silverado. Work Truck.. It does have On-Star (which I don't use) I want to use my factory remote.. The truck never had the remote start. From what I've learnt, I'd use the 3X lock button on the OEM remote.
Youtube video https://www.youtube.com/watch?v=8qYgw8yuLHk appears to be pretty simple... Doesn't meantion anything about needing a flash link or anything about "datalink" in the video so I'm not sure what i need regarding that....
Can you advise exactly what I need and if the video is accurate?
