    I recently got an alert that the battery in the key fob was low and needed changing. I tried the 2nd key fob and got the same message, so I changed out the battery, still getting the same alert. I tried rebooting, but the alert is still there. I have not called the SC and have been using the key fob with the new battery and all is good....for now. Does anyone know how to reset the alert? My wife is a little skittish about driving with the low battery message on the screen.

    Mine is doing the same thing. Even with a new battery. Might be RF interference from the phone or something els.

    I remember mine was a little funky with the low bat warning also. I think I had to show the car both keys after I replaced the batteries until the car would accept that they were fine. Meaning that after I got the low bat, using the second fob with a good bat wouldn't clear the alarm. I had to also show the car the first fob (with new bat) before it cleared.

    When in doubt reboot the touchscreen. That often works.

    Sorry to revive an old thread, but I'm currently experiencing the same issue. I replaced the key fob battery 2 days ago, and the message remains on the screen. Not to mention that for the second time in 2 weeks, the main screen seems to go out and completely reset itself like it's booting up again. This has happened while actually operating the vehicle...

    Called Tesla Center. They said I needed to change both batteries (CR 2032) and all cleared up. Make no sense, but it works...

    when I had a low battery alert, the only thing that would clear it was to change the battery on the other fob as well. Does not make a ton of sense, but it works.

    Ok, thx, will do that this evening. Definitely doesn't make any sense at all. What if you don't have another key fob..?

    after changing the batteries did you reboot the car?
    rebooting sometimes clears these minor problems

    I am reviving this because I'm having this issue. We left Florida and the second fob but was told I can't get that to reset or even use summon until I return to Florida. What the h*** Tesla

    I had the same issue couple of weeks ago with both key fobs. Paid a visit to my SC, got the battery replaced in my regular key fob, got the latest firmware upgrade and haven't had the problem since, even with the second fob with old battery.

    I'm going to a SC tomorrow. I don't like the fact I can't even use autopark which makes no sense. I can understand summon a bit more. We tried three batteries.
