I'm looking into installing a door lock w/ key pad at home for two use cases:

1. I'm out of town and need to allow someone to enter my home, in an emergency or for any reason.
2. Nice to have - "oh shit, did I lock the door" - ability to lock the door remotely from my phone, would also solve use case #1 by unlocking remotely.

If there are no privacy respecting / self hosted apps for remote control (use case #2), then a "dumb" electronic lock w/ key pad that enables me to set a PIN that I can give to a friend or neighbor in a pinch and then reset the PIN after I get home, that would be good enough. If no such keypad/electronic locks exist, then my backup plan is to just make a few copies of my key for trusted friends & family and/or hide a key, but I'd like to explore the keypad route.
