No Stupid Questions

From what I've seen? Considerably less secure.

Many of them feature a normal pin-tumbler lock cylinder as a backup in case the electronics fail, and best case scenario it's going to be as mediocre as any old Kwikset hanging on the peg on the comedy aisle at Lowe's. So you're probably still vulnerable to key theft, key duplication, picking, combing, raking, jiggling, etc.

Then there's the electronics. A surprising number of them rely on either a solenoid to directly operate the latch/bolt, or a relay that energizes a motor to do the same, both of these are vulnerable to attacks by magnets. A stupid number of them are vulnerable to disassembly attacks. There are trace evidence attacks such as looking at the keypad and noticing where all the fingerprints are, there's just watching you dial the combination...

And the smart phone app driven ones...sure, let's send a signal that means "I just got home" across the internet. That sounds safe.

"The weakest part of the door is the window (next to it)"
"You don't need a key when you have a brick"

In my case, definitely more secure. If I'd given my kids a key, my ex was likely to copy it without my knowledge. With a code, I could tell them to go ahead and give him the code if he pressured them, then just change it.

And I still have a non-electronic deadbolt.

Researched a bit into this some time back and I was not convinced.

It would be nice to have a lock I could assign entry codes for different users and still have a physical key as an emergency backup but the obcession with these locks being tied to an app and/or internet discouraged me.

I stayed with purely mechanical locks with complex keys and secondary arms that make the task to break down a door much harder.

Don't know how it is in other countries but I've been to shops where I specifically asked for locks that would give a locksmith a bad time to pick and was shown a few models where the only way to break it was to put a whole cutter to it and cut out the entire drum.

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.

One thing people aren’t considering is that if we assume that it’s relatively trivial to bypass either a classic lock or a smart lock, only one of the two is likely to give your phone a notification that it’s been opened in your absence.

Both at the same time. Different attack vectors

It's important to remember that no lock is entirely unpickable. It's just a matter of time, skill, tools, and know-how. Generally speaking, if someone is willing to pick a lock, they will be able to pick your lock eventually.

But arguably even more importantly, most people do not possess the skill, tools or know-how to pick a lock and will not try. So you get the same benefit from just about ANY lock for the vast majority of people that might break into your home, in that any functioning lock will deter them equally.

Also, even if you have the most secure door locks known to man, even if they are literally unpickable, that will not keep motivated people from entering your home through other means. Having a perfectly secure lock just means that it become preferable for them to break in through a window, by literally breaking in a door, by your crawlspace/basement access, etc. They could also catch you outside the home and use you to gain access by threat, trickery or theft of your keys.

So, to me, even if a smart lock is less secure than a standard lock they are both going to act as sufficient deterrence for most situations and the tangential benefits of a smart lock can be worth the marginal loss of security. But that's a choice you have to make for yourself.

Edit: Also, some features can make smart locks massively more beneficial to addressing a break in attempt even while being easier to actually break in. For example, there are can be some secret distress features, like a alert combination that unlocks the door but also secretly alerts the police of a break in. Or notifications that alert you that the door was unlocked even when you aren't home. Smart locks come with vulnerabilities, yes. But also unique features that you can't get with conventional locks.
