Are smart door locks more or less secure than traditional door locks?

Anything with added complexity will have a larger attack surface and more failure modes.

I have to disagree - this is more like the gate that blocks the sidewalk that you can get around by walking on the grass. The mechanical locks that these come with are significantly weaker, more common and better understood by thieves, that they wouldn't bother even trying to figure out how to hack the smart lock.

That doesn't invalidate their point. The electronic lock is just an additional potential point of failure with no added security. In addition to people who can pick or break the key lock, now there is an additional type of person who can break in: the kind that knows how to bypass electronic locks.

Same concept but why pick a lock when you can break a window or sliding glass door?

In other words... The attack surface is indeed larger for smart lock than dumb lock -- more ways to attack -- but in practice it matters little because existing home attack surface is easily breached.

PS the counter argument is smart locks come with added security controls: monitoring, logging, and the ability to auto lock in case someone forgets to lock it.

What would you recommend?

Honestly, the lock is one of the last things to worry about. If you have an outward opening door get security pins for your hinges.

Check out one of https://m.youtube.com/@DeviantOllam talk on door security and worry less about the lock and more about the door fixture. His hour long conference talks to through how a door is insecure how it can be exploited and what you can do to prevent it from happening.

Absolutely right! By far the majority of burglaries are with forced / destructive entry. Virtually all. That makes me think: if there is a "lockpicking lawyer" out there, what else lockpicking is there...?

Typically, external residential doors open inwards so that they can't be blocked by someone on the outside. Of course this doesn't apply if we're talking about an internal or non-residential door.

It is region specific as in my place 2 out of 3 of my external doors open outwards. my place before that was about 50:50 for outwards or inwards opening doors.

I'm not sure. Honestly, it was mostly observation, and not straight fact. Perhaps it just more common on more recent construction. I don't think I've ever been aware of an apartment or house door opening outward, except for screen doors on the outside of regular doors.

Trying to think through all doors of all places I have lived personally and I can not remember a single inward opening door in a house, cottage or apartment. I could very well be wrong but nothing comes to mind.

Based on the context, I think they would suggest going with the old school lock with a deadbolt. The more complex a device is, the more likely it is to have multiple vectors of attack.
