Display/FOB issues
I've had service twice on display issues, first was flash and replace module a year ago due to a blank screen at start, subsequently came on. Second was a month ago, both screens were our after a three hour trip, came back later, again another reprogram. Now the system won't recognize the FOB more than a foot away, even displaying a message to insert it into the column. Other GM cars works with the FOB in my pocket? Something new with programing?

Bad "new" fob batteries seem to be fairly common. Maybe try another battery? Have not seen any threads related to bad fobs - except for one chewed up by a dog. All apparently resolved by a good battery.

All I'm suggesting is that sometimes a new battery has been on the shelf for a while or is just plain defective. Test the battery with a volt meter, try another battery, or swap batteries between your fobs. I bought 12 brand name batteries online and a couple were dead. I change all fob batteries whenever one gives problems like decreased range. 4 cars / 9 fobs.
It has been suggested to avoid the brand with cross hatched back surface.
If it does turn out to be a bad fob they are available. At least you won't have to get a key laser cut. You'll need to delete all fobs from the car's memory so they can be assigned as #1 and #2. Just adding a 3rd fob makes it #3 which won't have seat memory functions.
Good luck.

Busy Woodward Dream Cruise last week.... New battery checked 3+ volts, gently cleaned contacts and and increased the tension.. back to normal operation. The display after 2 service visits initially took a couple seconds to appear, now back to normal. I was thinking this might be related. Thanks for the advice! and
