What if your phone ran out of power though?

You could have a magnetic switch somewhere that you could tap SOS on with a magnet or something. Or just knock on the door with a certain pattern. Or speak "Open the pod bay doors, Hal" into a pinhole mike. I'm sure you could think of many methods.

And when your house has no power?

The second half of your post is survivor bias. The first part of your post is pure hyperbole. There are plenty of places less crime ridden then Baltimore or Detroit where you absolutely have to lock your things or they are likely to get stolen. Pretty much any urban area in the US. Most suburbs as well if you park on the street. Kids will go down and just try doors. They have no intent of picking anything or forcible…

This is not even a US specific issue. Vancouver, BC has a serious problem with (heroin, meth, cocaine) addicts and property crime. Theft from vehicles and from vehicles in supposedly "secure" underground parking garages is epidemic. No bicycle worth more than 50 dollars is safe locked in public, no matter what kind of lock it has on it.

Vancouver is probably even worse. Not only is crime rampant, out of misguided compassion for drug users they have for all intents and purposes decriminalized petty crime in a sizable section (DTES) of the city. Police will quite literally not even arrest repeat "frequent flyers" even when seen seen prying into buildings and security gates.

> Essentially everyone has stolen at some point in their lives Isn't this a fairly wild claim? I've never stolen anything and can't imagine doing so. That's a pretty dismal view of the human race isn't it.

I don’t think they’re suggesting that everyone on earth has purposefully become a thief at one point, but that sometimes it just happens. I’ve definitely walked out of a supermarket with a bottle of water that I picked up while shopping and forgot to pay for - I still stole it, even if unintentionally.

How often do you unintentionally walk into someone’s unlocked house and steal something, though?

Turns out powers tools work well on non-Turing complete locks too. The interesting part of the threat model for smart locks are cases where a physical attacker is _not_ present.

The article points out that the lock casing is made of aluminum rather than steel (presumably for aesthetic reasons), which is trivially easy to drill through. A steel casing would take a lot longer and make a lot more noise.

The point is that people in the market for smart locks need to additionally vet the company that makes them for their proficiency in physical security, not just in software security. A competent company that has made non-smart locks for a while would not make this same mistake.

My pet peeve is smart dead bolts. Presumably if you have a dead bolt you are worried enough about security to pay for a lock that's stronger and harder to subvert than a normal door knob lock. After all using 2 keys/locks is a hassle every time you open the door. Presumably because you don't want anyone with a shim/credit card to just pop your latch. Most would expect a dead bolt to survive a 5 second attack from a 1…

I (and I assumed everyone with a dead bolt) only ever lock the dead bolt. What's the point of locking the door handle if there is a dead bolt?

I mean, it’s there; you might as well.

I've unintentionally stolen dozens of lighters from the houses I've visited while I was a smoker.

That's... not what the parent upthread said, though.

Easier way to open a smart door lock in 3 seconds...use a hooligan tool[1]. For $150 USD a SWAT team(or someone who practices for a few hours) can be in your room in no time. [1] https://en.wikipedia.org/wiki/Halligan_bar

Yes. The truth is most (and I mean nearly all) residential door frames snap like a match stick with a hooligan tool. In a previous life I kicked in doors for a living. I don’t give a fuck how cool your dead bolt is. I could be in your face before you were out of bed. If you want to keep out lazy thieves any lock will do. If you’re preventing against a dynamic entry you need trip wires, man traps, metal door frames, a…

Metal door frames here. No comment on the others.

-Anecdotal, but indicates there's a certain honour among thieves - if you volunteer to visit inmates in Norwegian prisons, you get a parking pass to keep prison staff from having your car towed or bike removed while you're visiting.

An inmate advised me that I should just leave that pass on the windshield at all times - as it would be more effective against theft than any immobiliser.

I did leave it in place, and a few months later, just about every car parked curbside down my street had had its stereo and valuables snatched - except mine.

Now, obviously, this may have been a result of my stereo being pretty basic, though of recent manufacture from a renowned brand - but I like to think it was because of the visitor's service pass.
