I don&#x27;t think using the phone app is particularly impractical. It&#x27;s usually as convenient to access as the key fob is, and unlocking it and launching the app isn&#x27;t <i>that</i> hard.<p>I will admit that the first thing I did when I got the update that defaulted to dead-man&#x27;s-switch operation was to put it back the way it was. But I was careful to understand the implications of what I was doing, at least.
