I used summon all the time, worked great. Recently, it stopped working using my key fob (either one of the two I have.) Still works using the smartphone app. I tried looking at settings but found nothing wrong. I used to long press the roof button, the car would beep, 4 way flash and fold mirrors and then I could press either the trunk or the frunk button. Now the car simply locks when I long press the roof button. Any ideas?
