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

Why is everyone calling this "hooligan" instead of "Halligan" tool?

A primary point of a lock is to keep people from acting impulsively. Consider these scenarios, ordered by decreasing likelihood of "yes, you would peek your head in" — or "yes, you would slip in and steal something": If your neighbor leaves their door open, do you peek your head in out of curiosity? If your neighbor leaves their door unlocked, do you open the door and peek your head in out of curiosity? If your neigh…

If the door is open and that is an unusual occurance, sure, I would knock on the door frame and call out to make sure they are alright / didn't forget to close the door, etc. For every other situation, no, I wouldn't.

Yes, thankfully, closed doors are enough for most people to curb their curiosity :)

His magnetic attack[1] on a common commercial lock that's no longer in use was entertaining too. [1] https://www.youtube.com/watch?v=cCay5ek_cW0

What? No longer in use? Those things are still widely in use in many mid century and older education and healthcare buildings around NYC.

I assume this specific model is no longer in use. Sorry, I should've been more clear.

From his comments, I don't believe the vulnerable ones are still out there. But, maybe they are.

I'm just not all that curious, to be honest. It doesn't need to be curbed, I don't care what you have in your house. Is this really a motivation that other people feel?

Looks like it was originally named for the creator(Halligan) but I'm guessing someone people made the mistake of calling it hooligan and there wasn't enough pressure to correct them.

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…

This isn't true - modern standard domestic polycarbonate and metal composite doors and frames with locks that engage all the way up are a real problem for the police as they're extremely hard to get through even with repeated blows from a battering ram. There is absolutely no chance whatsoever that you can kick in a modern door. You will break your leg first.

Do people have doors like that? Mine looks like a bog standard wooden door. Even the fanciest condo I lived in had a massive heavy fire door with hella heft but it didn't look metal.

The lock is still in use but the vulnerability has been fixed in newer models and older models can be fixed by a part kit.

Oh, interesting. I thought most of them had been replaced with the newer versions. I didn't know about the replacement kit. Now that you mention it, I guess LPL might've said something about it in his video (which I didn't re-watch, oops!).

Thanks! Very informative!

You have to explicitly want to spend money on that type of door. Looking at random model houses in the US, i have yet to see anything that comes with that type of door. Most apartments dont generally have high security doors either (landlords dont care, its not their stuff that gets stolen). Most front doors where i live can be punctured by leaning on them in the wrong way, and may as well be cardboard.

He mentions the mech was changed in 2011, mentions there’s a probably little used retrofit and at the end of the video he comments that there are likely many compromised ones still out there.

Which is pretty expected if you've seen how buildings are maintained in general. I haven’t encountered a lock that doesn’t have this vulnerability in any 20th century post-war nyc building.

Yes. Not as many, but a few!
