    Yesterday, I could not lock or unlock my 2019 Prius LTD. I was able to gain entry and discovered that my battery pack for my cell phone was still plugged into my power port. I believe that this created some type of feedback loop. Once I unplugged it, all returned to normal. Thoughts?

    It'd be interesting to re-try it - to check that was the actual cause, and not some freak coincidence.

    Well, I tested again and same problem. Is this a defect in the software, hardware or something to just live with? Thoughts?

    Wow. I've had exactly the same problem with the same cause. Also if I have my old phone charging on the passenger seat it triggers the TPMS alert after half an hour.

    In both cases, I'm pretty sure it's just interference from the devices. Both chargers and phones produce a lot of RF interference at lot of frequencies (GSM, 2x WiFi bands, BlueTooth, NFC, etc).

    SM-T813 ?
