    Here's my latest wish-list item (albeit a minor item):

    I would like to be able to go into Controls/Settings, or, maybe some new app, where I fire up a page that says "press your keyfob button now" and you do, and the car comes back and says, "your keyfob battery is currently at 46%" or whatever. So, I can know when it's getting close to time to change the CR032 battery.

    Of course, it might require a new type of keyfob from Tesla, one that would send battery-charge-level data to the car when asked. I doubt that is in the current communications protocol.

    Yeah, the alternative is to take the battery out of the fob and test it with a voltmeter or whatever, but I don't wanna do that :)

    Another of your great ideas. Until Tesla addresses your concern with an app feature, I'd suggest having an extra fob battery in your glove box . . . or maybe in the side door pocket when they get around to that enhancement!

    The car will give a notice when it senses the fob with a low battery.... However, I wouldn't wait or rely on that. I keep a spare in the glove box.

    Cool, if that is true, then the keyfob must actually communicate battery strength to the car already. Good to know.

    It’s cheaper for Tesla to send you a new battery every six months / year than to pay for the development of a battery level monitor UI. I’m not saying they won’t do it some day, but those FOB batteries are cheap
    Here’s a 10 pack for $4.64
