I have a 2020 Silverado 1500, 36,500 miles with the same “Unable to detect key fob” problem. It has happened twice so far and has cleared itself overnight both times and then the fobs work correctly. I have been able to put the fob in the fob “pocket” in the console and drive it both times.
The first time it happened, my daughters 2019 Jeep Grand Cherokee was parked next to it overnight and her vehicle had the same issue. Way too coincidental!
I don’t believe my issue has anything to do with window tinting. Mine were tinted about 6 months ago and no problem until now.
Mine is going to the Chevy garage Monday. I would like to hear if FirstAscent has an update/fix or anyone else.
Thanks
