A forum PSA...
Just replaced key batteries(CR2032), both remotes.
Car in service for a little over a year, approximately 4,500 miles. If you've got some spare time and you're batteries are older than this and you haven't changed them before, make it a point to do so.
I can be all thumbs sometimes, I thought the procedure
was more involved than it should be for a battery swap.
Patience pays when snapping covers on.
Original batteries measured 3.02v, new measured 3.23.
Procedure starts on page 6-29 of 2021 manual.

over two years ownership on mine and they still work fine, you can always keep a 2 piece battery pack in your console or glove box just in case 😄

I’ve changed mine after more than two years. It started to report Replace key fob battery or something similar. It was working ok for 10 days or so, and then I replaced it. Really easy job
