Not sure if this topic has been covered or not, as I did not see anything related in the forum. So, how do you go about replacing the batteries on your key-fob, one of them is fully dead and the other has a low battery warning message every time you start the car.

Our Ascent is a 2020 model, so once you replace the battery do you have to re-sync the fob with the car? And can that only be done at the dealership, as I am trying to avoid going there since the subaru service dept at both dealers that are close me, are just plain bad.

Thank you!
