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.

      Am I?

      The one attack vector you provided that actually applies here is something that would require technical experience above what your average thief would reasonably have. But with a keyed deadbolt, a lot of those can be raked, picked, or opened with a Lishi tool.

      So yeah, you’re right that there’s a vulnerability when locks are paired. But that would require someone to either be within range when that happens or to place a battery powered device and pick up that information the next time pairing happens. Pairing doesn’t happen very often. I think the last time I paired any of my locks was over a year ago.

      But with keyed locks, an attacker wouldn’t have to wait for me to do anything, they could just walk up and pick the lock with tools that are easier to get and understand/use.

      Going with your reasoning, the two videos I’ve shared about picking deadbolts would mean that keyed locks aren’t secure either.

        Two words then: Flipper Zero

        You’re behind the times on this one. This is a common tool used to defeat all kinds of locks. The Z-Wave exploits have been around for a LOOOONG time now. There’s also BT and RFID exploits as well, hence the CVE is posted above.
