Key fob battery low message won’t go away

[chjch]

I can't simply let that go without my two cents. I have to first ask, have you looked in the manual? You didn't say you did.
I will admit, I already know this (from reading one of the previous versions of the manual for my car), so I am not going to look at a more recent version to see if it is there. But I can't imagine it not being in the manual.

It isn’t in my manual. I’m reading it now. Of course it took so long to load on my screen that it could have changed since I pressed the button. Good thing I’m using decent wifi
