I have a smart lock and tbh hate it. I’m not sure the security difference, but it’s more inconvenient than a key, takes longer, needs me to pull out my phone, open an app and then I can unlock my front door.

Unfortunately getting away from them in moderately upscale apartments is getting harder and harder.

dogslayeggs ,

I absolutely love my smart lock. It has auto-unlock when I arrive home after leaving the neighborhood, so I never have to use a key or a phone app. It also has a key pad, so if my phone is not on me or is dead or whatever I can still punch in a code. And I can both check the lock status AND door open status anywhere I am in the world if I have wifi or cell data. I can remotely unlock the door to let in my housekeeper if I am at the office without giving her a code. I can also lock it when she leaves.

BURN ,

That’s a much more fancy one than mine then. The only feature I have is remote unlocking. Nothing else you mentioned is a feature of mine, so that may make sense why I dislike them.

I’m not even able to lock my door remotely, let alone check status or if it’s open. The only way to lock the door is physically using the deadbolt from the inside, the app offers no way to do it.

dogslayeggs ,

Ahh, yeah, I can see how that would be annoying.

BURN ,

Yeah, it’s not great. The door had a keyhole so when I signed the lease I was really expecting to be given a physical key to unlock the door, but they wouldn’t even give us those.

A fully featured lock might be worth it, but with the one I have now it’s not great.

schmidtster ,

Well than that’s a proprietary lock, I don’t think that falls under the umbrella of “smart”.

BURN ,

If it’s internet connected it’s considered a smart lock imo. I’m not sure what distinction you’re trying to make.

Anything that requires the use of my phone for something that could be done just as well with a physical item is a bad product imo. I don’t read on my phone, I don’t ever want my phone to be my car key, I don’t like having smart devices in my home.

SmashingSquid ,

I have an august lock that has auto unlock but the Bluetooth radio is so weak it never unlocks. I usually use Siri on my watch to lock/unlock. Next place hopefully I can get one of those homekey tap to unlock ones.

I hope you didn’t pay much for your lock if you can’t even lock it with the app, that’s a huge deal breaker. I don’t remember the last time I used a key.

BURN ,

I live in an apartment building, so I had no choice in the lock, but also didn’t pay for it.

Never tried Siri for it, but I also have Siri disabled on my phone. The watch app is a PoS with this and doesn’t work unless you open the app on the phone too.

I’m sure there’s better options out there, and my sample does seem to be a pretty low quality one, but I just don’t really find a need for one. I’d much rather have a physical key tbh. I’ve almost been locked out because I don’t always take my phone when running the trash out and I’ve bumped the front of the lock with my back and it auto locks me out.

slazer2au , to nostupidquestions in Are smart door locks more or less secure than traditional door locks?

Less. Look at any Lockpicking Lawyer video on YouTube as he demonstrates in real time how bad they are. Most of his videos are under 5 min

If you want to really turn yourself off smart locks check out any DefCon talk about smart locks or “smart” devices in general.

dogslayeggs ,

And most dumb locks can also be picked in under 5 minutes. The difference is a smart lock can alert me when someone who isn’t me opens the door or leaves it open. Of course, most burglars are just going to break a window to get in.

Madison420 ,

There should be a separation between fully mechanical locks with electronic monitoring (ideal) and a mechanical lock with vital electronic components.

Natanael ,

You can get a lot of locks which allows you to connect external mechanisms which can do just that. Don’t know anything ready out of the box, though

bigdog_00 ,

SwitchBot makes a retrofit deadbolt controller that straps onto the inside

schmidtster ,

Funnily enough, if you have the best lock they’ll just break your door or window instead.

Much cheaper to replace a lock than the entire front door.

Something to keep in mind, also lots of smart locks down have a keyhole to pick, so they would actually increase your security when compared to most regular lockset.

tonyn ,

I just watched LPL pick a smart lock with no keyhole. He just had to shove a bit of wire in the drain hole at the bottom. 🤦‍♂️

schmidtster ,

Right at the start dude….

Designed for administration of high occupancy.

Those are second line in those cases, that’s not supposed to go on someone’s front door…

TheIllustrativeMan ,

You want them to break in for insurance purposes though, it’s a clear indication of unauthorized entry. Your policy should cover the door/window, but if your lock gets picked/bypassed you’re going to have a rough time getting things covered.

schmidtster ,

Why would they need proof of forced entry? Is that seriously a thing where you are?

DogMuffins ,

This just isn’t true.

maporita ,

A previous owner of my apartment had for some reason installed a high security door. It’s 5 inches thick with steel plates inside and has 3 separate sets of 3 locking rods like a bank vault. Not sure what line of work they were in but, really, good luck to the person who thinks they can break in here easily. Downside is there is no way to put a digital lock on the sucker.

I would be worrying about fire fighters won’t be able to enter my apt when they need to.

Followupquestion ,

Firefighters train for exactly such scenarios and will happily go through a nearby wall. The cops struggle with armored doors, but the guys with axes don’t bother.

ImFresh3x ,

My smart lock doesn’t change the locking mechanisms. It’s basically a robot on the inside that turns the lock like you would. The only security issue would have to be software side, which a typical thief isn’t going to bother with especially since you cost tell from the outside that’s it’s not a normal lock - because it is.

August lock btw.

meekah ,
@meekah@lemmy.world avatar

I agree that most thieves won’t bother - but they do now have the additional option to hack it, making the lock less secure in total, not to mention the flawed mechanical design many of those smart locks have.

ImFresh3x ,

Yeah I’m just saying in my case they have no way of seeing that it’s a smart lock at all. The only smart part is an attachment on the interior side. So mechanically it’s 100% the same, and there is no visible indication that is “hackable,” even if it were. My door and it’s lock look as just like it did 15 years ago.

malloc ,

most of the smart locks that are supposed to be drop in replacements for traditional locks are mostly trash.

Personally been eyeing upgrading to UI’s access readers, but it lacks features like door unlock with Apple Homekey (for now anyways since it requires some specialty hardware). So been holding off.

This particular product is geared towards small business and large enterprises. But can be setup for home usage if you have to technical expertise.

Shurimal ,

Burglars won't pick locks, though. Breaking the door, door fixture or the window next to the door is much faster, easier and requires very little skill.

schmidtster ,

Lots do, less common with more modern locks, but a bump key is a very quick fast way to try and get in.

AA5B ,

I doubt it. Bump key requires a tool and a skill. The bar is not high but there is one. My understanding is most burglaries are impulse or opportunity. Is something open or unlocked? Can I break it with my boot or a nearby rock?

schmidtster ,

Doubt what? A proven issue?

A bump key requires zero skill and a set of 10 will net you around 90% of current doors. And skill? It’s a 30 second video to watch, if you even need it. You push the key in and turn at the same time. If it works it works, if it doesn’t you move on. Even a trained professional can’t get into every single door, it’s about ease. If it doesn’t work, they move on.

AA5B ,

I doubt it’s used frequently to break and enter. Burglaries are much more opportunistic

schmidtster ,

It’s used very frequently…. It’s hard to track though since it leaves no trace if done right. Most people would just think they left their door unlocked.

But of course very few people are going to admit that either.

I seriously don’t know why I’m arguing with you or why you think that your opinion matters.

It’s a known issue, simple as that. They are illegal to own without a locksmith license for these things exact reasons.

Ignore facts if you want mate.

AA5B , (edited )

My opinion doesn’t matter as yours doesnt, just actual facts.

I didn’t spend enough time finding data but this is representative of data I’ve read

www.adt.com/…/how-do-burglars-break-into-houses

Edit to add: here’s an article from “Bump Key and Lock Picking News”

ukbumpkeys.com/…/how-safe-is-your-home-i-ask-a-th…

schmidtster ,

He bought lockpicks…. Not a bump key…. Said that they couldn’t use it to pick their nose…. And it’s one persons opinion…. Lord have mercy.

They work, and if you use the right terms you’ll find plenty of supporting evidence.

Try using bumpkey instead of lockpicks for starters……

AA5B ,

I never disagreed with whether bump keys could be used, just whether they are.

There are lots of ways you can get sophisticated to break into pretty much any home, to get around various security doors, locks, alarms, dogs, cameras: a homeowner can never keep out a determined sophisticated burglar. I’m arguing that those are extremely rare and would need sufficient payoff, so it’s also not worth worrying about for most of us.

The bar might be low on using a bump key, and I do see plenty of scare stories in the media about how available they are, but none that I read ventured to say how frequently they’re actually used.

However actual crime stats continue to say you need to worry about the basics, and bump keys are either not mentioned as a frequently used tool or are not frequently used. I’m not claiming my house is secure against them; it’s not. I’m saying that if I get burgled, it’s much more likely there was a door open, or a door kicked in, or a window broken. The cause will be the blinking lights visible through the windows indicating potentially valuable electronics, and it will likely be a smash and grab. No bump key involved, no finesse of any kind

HidingCat ,

LPL is quite a bit better than your average thief though, and if you attract enough attention to have this kind of expertise thrown at you, you need to worry more than just locks.

fubo , to nostupidquestions in Are smart door locks more or less secure than traditional door locks?

Against what sort of attack? Who’s the attacker? What capabilities do they have? What do they want?


There’s a saying, “locks are to keep your friends out.” If someone really means you harm, a lock is not going to keep them out: they can smash a window, break down the door, or hit you with a rubber hose until you give them your keys or passwords. This applies no matter what kind of lock you have.

But a lock represents a social barrier: everyone knows that trying to defeat someone else’s lock is a hostile act. The law recognizes this in many places: breaking-and-entering is a more severe crime than trespassing.

A lock may slow down an attacker. It may redirect an attacker to go after your neighbor’s stuff instead of your stuff — but not if everyone has locks.


A password lock has some advantages over a key lock. You don’t have to issue physical keys to everyone you want to allow in. Many allow you to create and revoke passwords separately — so you can grant a friend access to your house while you’re away, and then revoke it when they no longer need it.

However, a password lock also has some disadvantages. If you give a password to one person, that person can easily give it to everyone. That’s a lot harder with a physical key, because they’d have to go make a lot of copies of that key — which, if nothing else, costs money and time.

A computerized lock can create an audit trail: it can record when it was opened, and even which credentials (passwords, keys, …) were used to unlock it.

Any lock can have vulnerabilities — most common key locks can be picked; computerized locks can be attacked through their computer hardware or software.

en.wikipedia.org/wiki/Rubber-hose_cryptanalysis

In cryptography, rubber-hose cryptanalysis is a euphemism for the extraction of cryptographic secrets (e.g. the password to an encrypted file) from a person by coercion or torture—such as beating that person with a rubber hose, hence the name—in contrast to a mathematical or technical cryptanalytic attack.

cloudless OP ,
@cloudless@feddit.uk avatar

It is for a house in a residential area, and I don’t keep a lot of valuables in the house. I wish I knew who the attacker would be, so I can catch them with pre-crime.

fubo ,

If you’re concerned about burglars, one problem is that if they decide to hit your house, they can just break a window.

Where I live, burglars often hit cars rather than houses; and they’re very willing to break windows to get in, especially if they see something valuable in the car. They spend no time trying to defeat the locks — hell, some don’t even check if the car is locked. They’re pros; they’ve practiced smashing a window and looting the car quickly.

A lot of the loss due to burglary is the damage the burglar does on the way in, rather than the value of the things stolen. And upgrading locks does nothing to reduce this.

Maybe instead of upgrading your locks, you might be better off spending the same amount of money upgrading your insurance?

SlightlyMad ,

Are you an insurance salesman? Because this script probably would have worked on me!

fubo ,

Here’s a sillier economic take on it:

Locks should be difficult enough to break that if you can develop the skills to break them, you’re smart enough to get a real job and not be a burglar.

bluGill ,

Cars have historically been broken into and stolen a lot. Thus auto makers have put extra effort into good locks. Some hardware store deadbolts are so bad you anyone can pick them with lock picks - no instructions needed. Only the best deadbolts are equal what a car has. Likewise breaking a car window is typically harder than breaking a house window.

MelodiousFunk ,
@MelodiousFunk@kbin.social avatar

Likewise breaking a car window is typically harder than breaking a house window.

All it takes to break a car window is a single tap. There's specific tools available, or someone can just use a shard of ceramic. Shatters completely and instantly.

bluGill ,

Right, if you have that tool. If you don't have that tool though a rock you find won't work unlike many house windows.

MelodiousFunk ,
@MelodiousFunk@kbin.social avatar

$10 on Amazon. Or just a piece of broken spark plug. Anyone who seriously wants to break a car window will have something handy.

Or maybe thieves are just walking down the street and see a fancy bag on a seat and a rock and just decide to do the deed on a whim and get foiled by tempered glass. ¯_(ツ)_/¯

bluGill ,

Shhh, most thieves don't know that and are taking cheap opportunity.

dogslayeggs ,

I love my August smart lock. It auto-unlocks my door when I get home, so I never need keys or to reach for my phone. It also has a key pad to unlock if I dont have my phone. It has alerts and reports status on an app. I can unlock or lock the door remotely for people to check in on things for me while Im away.

Yes, it has issues and eats batteries, but its so convenient.

What would you recommend?

OberonSwanson ,
@OberonSwanson@sh.itjust.works avatar

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.

slazer2au ,

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 m.youtube.com/ 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.

sagrotan ,
@sagrotan@lemmy.world avatar

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…?

moody ,

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.

slazer2au ,

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.

moody ,

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.

papabobolious ,

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.

cerevant ,

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.

moody ,

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.

agent_flounder ,
@agent_flounder@lemmy.one avatar

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.

agent_flounder ,
@agent_flounder@lemmy.one avatar

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.

Izzy , to nostupidquestions in Are smart door locks more or less secure than traditional door locks?
@Izzy@lemmy.world avatar

If there is no keyhole to pick then it is probably marginally more secure, but if a burglar wants to get into your home then no door lock is going to stop them. They could just break it or break your windows.

stevehobbes ,

This is it. The weakest part of most doors is the door. A sledge hammer will go through a door or window regardless of the lock.

Smart locks are way more convenient and the ability to grant timed access and unique access controls probably makes them more secure.

    This is why you need backup measures. For example, if they break in through my windows, they’ll be foiled by the micromachines I placed strategically on the floor. If they break through the door, they’ll have to contend with the blowtorch I have rigged just inside the entryway. Always remember, “this is my house, I have to defend it.”
