    I've had my X 30 days. Have already had to change key fob battery twice. Anyone else experiencing your fob ripping through batteries?

    If you keep your key close to the car, then the battery will drain more quickly. Try storing the key at a greater distance from the car.

    I keep mine in A RFID blocking pouch available on Amazon. No such issue for me. It was initially reported in the very early models which was resolved after changing the battery. There is a thread on this issue plenty of suggestions there.

    You likely need to have your FOB firmware updated. This is a known issue that was corrected on my last service visit. So a call to your local SC (and then a visit with both your fobs) should take care of it.

    Funny you should mention this. I just took delivery of my car a few short weeks ago and yes my battery died yesterday while I was out. Luckily I had my iphone App and could open and start the car but was surprised that the battery would die after such a short time. My Model S battery would last a lot longer. I never store my battery close to the car so this is pretty surprising.

    Yeah, if you live close enough to a Service Center, that's your best bet. Bring both FOBs. They'll change the batteries and update the firmware on them.

    Your battery may not actually have died. The fob's themselves have an issue and get confused. I had to keep taking my battery out and reinserting it every few weeks. Nothing wrong with the battery.

    They have reprogrammed the fob's but it has only been a few weeks so too early to tell if they have actually fixed it yet.

    One of my two Fobs battery died after only 9 weeks. Interesting, it is the one I don't use regularly and it is stored even farther away from the MX than the one I use every day! Worries me enough that I'm keeping an extra battery inside the key fob silicon holder for emergencies.
