Dead key fob battery ?

[Ghost10]

I’ve noticed just today the drivers side button on the exterior handle doesn’t lock or unlock truck
Sometimes when I get in it and try to start it says fob is not present even though it is.
Tonight I got this on my DIC….

I had similar issue plus short fob range so I tried the fix in this post https://www.tahoeyukonforum.com/threads/2019-yukon-key-fob-range-blows-what-would-you-do.112937/ and everything is fixed for now
