Try this first and we go from there in case was a glitch
Master Reset1-Disconnect Both Battery Cables ,Positive & Negative .
2- Touch Cables With Each Other For 60 Secs ( this will take any residual power in the Harness to Reset the Vehicle Modules )
3- Wait 30 min
4- Close all doors and trunk
5- Reconnect Battery Positive First
6- Use The Key in The Driver Side Door
Lock Cylinder to Lock it & Unlock,IF You have only a Key Fob ,use it to lock and unlock

unfortunately at this time you will needed scanned with factory scanner or equivalent and read key less entry fault codes and based on these fault code we can pull up a pin point troubleshoot and be accurate

you can post them back here and i can help further

now with that said i suspect on 2016 the key fob lost sync with vehicle receiver and needs reprogramming or replacement where the rf signal to unlock is nt being sent

but we need to be sure with a scanner

sorry i wish there was one answer for this

now if you have 2 key fobs try the other if u have not already ,if it did work then we have a door module/bcm module issue but again we needs these fault or it will be a guess and end up throwing parts at it

You are very welcome :)
