    Things might be different by now, but when I was researching this I decided on the Yale x Nest.

    It’s more secure than a keyed lock in the following ways:

    • Can’t be picked (no physical keyhole).
    • Codes can be revoked or time-gated (for example, you can set the dog walker’s code to work only at the time of day they’re expected to come by).
    • Guest codes can be set to provide real-time notifications when used.
    • The lock keeps a detailed log of every time it’s used.
    • The lock can be set to automatically lock the door after a certain amount of time.

    It’s less secure than a physical traditional lock in the following ways:

    • Compromise of a keycode isn’t as obvious as losing a key, so you might not change a compromised keycode the same way you might change a lost key.
    • People can theoretically see a code being punched in, or intercept compromised communications to use it.
    • Compromised app or login could be used to assign new codes or remotely unlock

    It’s basically the same level of security in the following ways:

    • The deadbolt can still be defeated with the same physical weaknesses that a typical deadbolt has: blunt force, cutting with a saw, etc.
    • The windows and doors are probably just generally weak around your house, to where a determined burglar can get in no matter what lock you use.
    • Works like normal without power or network connection (just can’t be remotely unlocked or reprogrammed to add/revoke codes if not online)

    Overall, I’d say it’s more secure against real-world risk, where the weakest link tends to be the people you share your keys with.

      Some smart locks are vulnerable to being manipulated with a magnet, if they’re poorly designed, since someone can just manipulate the motor from outside.

        I’ve seen it for keypads that have to send a signal to an actuator located elsewhere, but I think the typical in-door deadbolt (where the keypad is mere millimeters from the motor itself) wouldn’t have the form factor leaving the connection as exposed to a magnet inducing a current that would actually actuate the motor.

        Most of LPL’s videos on smart locks just defeat the mechanical backup cylinder, anyway. I’d love to see him take on the specific Yale x Nest model I have, though.

      But since smart locks generally also have a traditional mechanical mechanism for backup, aren’t they inherently always less secure than a traditional lock since you can find the weakest link in either of the two mechanisms?

        Usually yes, but this person is saying theirs does not have a physical keyhole.

          Yup. The backup for battery failure on this model is that the bottom of the plate can accept power from the pins of a 9V battery, held there just long enough to punch in the code.
