"No combination to forget!" "You can open it with a directional code!" ...okay.

[@ZylonFPV]

The smiley face on the motor and the "woooo!" Sound effects made my day :D

[@aljoschi]

The Masterlock is indeed vulnerable to magnetic attacks. In the video of the talk "Lock picking the IoT", from the chaos communication congress 2016 media.ccc.de/v/33c3-8019-lockpicking_in_the_iot#video&t=2725 at ~43:30 it is shown, how the Masterlock can be opened with a moderately sized magnet. Rotating the magnet at the back of the lock moves the motor and opens it in seconds.

[@jackwhite3820]

nice!

[@Hainaa]

I love how the lock says "FOR INDOOR USE ONLY" but you keep making references to outdoor stuff such as locked bikes.

[@ZacharyParrott]

While the app wasn't working as fully advertised... it does work if you played around a bit more. I've had to hold the lock icon within the app and then get prompted to press any key on the lock. My university's makerspace uses a few of these locks to lock tools that require certain training. When you complete the training the lock is shared with you. Maybe not ideal, but there are applications.

[@jeffreymurdock8366]

It has a combination as well as bluetooth capabilities. I used several of these with the same combination and never had problems with the bluetooth part. With that I liked not having to worry about grabbing my keys to get something from the storage areas.

[@Landrew0]

I just love these videos that get Dave worked up into a squeaky frenzy.

[@ForViewingOnly]

So glad you gave a groan at the idea of a Bluetooth padlock at the start of the video. I wouldn't have known what to do if you'd said "What a great idea!". The last time I face-palmed at a device as useless as this was when Oral B released a toothbrush that could communicate with a smart phone app.

[@SirElliottatk]

ForViewingOnly not to mention anything Bluetooth is a security problem

[@EEVblog]

I groaned at that one too. My Oral B vibrates to let me know how long I've been brushing, no stupid app required.

[@johnfrancisdoe1563]

EEVblog Mine vibrate while I brush, kind of the primary function.

[@zvpunry1971]

Instead of paying a lot of money to buy one expensive electric toothbrush. Buy several manual toothbrushes, one for the office, one for the glove box in your car and so on. And have dental floss everywhere and use it. Teeth should be cleaned directly after every meal, especially if it contains a lot of fermentable carbohydrates. If you drink sweet lemonades or acidic juices, just rinse your mouth with water. That is a lot more effective then waiting until you are at home to use your high-tech electric toothbrush, because when you arrive at home, the damage has already been done. Dental hygiene doesn't need the Internet of Things or Bluetooth or electricity or stopwatches or colored stripes in the toothpaste, it needs some minutes after every meal and discipline to do it. :-)

[@Draugo]

Expect studies have concluded that it doesn't make a lick of difference if you actually brush your teeth before or after your breakfast for example so that kinda goes against you "immediately after each time you eat" idea

[@micsky99]

We use these locks to secure the transport of exams to a examination centre. The great thing about them is that we can provide controlled access to the exam papers. Once the exam centre has the zoom session up, our remote invigilator provides the guest code which is single use to open the exam paper box. Once the exam is complete the put the papers back in and lock the box again. No one can get back in now as the guest code is single use. We put a few single use guest codes in in case it needs to be reopened under supervision.

[@DoRC]

It's an indoor lock so forget locking your bike or your shed with it. Or most other places where a padlock is used....

[@FindLiberty]

If the battery dies or control circuit happens to fail due to moisture or EMP, *MAGNETIC COUPLING WORKS GREAT TO OPEN YOUR LOCK!* The tiny internal lock/unlock motor can be spun via an external magnet turned against that area on the rear of the ALUMINUM lock housing. Use finger power or a small rechargeable drill fitted with an external (spinning) magnet as an emergency backup "key" for your lock. EEVblog Dave could design a multi-phase drive circuit to power the stator coil of an old electric motor (just large enough to slide over the failed lock) in order to open it up in a jiffy _...and quicker than you can say, "GUILTY", uncle Bob's your cellmate who's also in, like Flynn!_

[@filipsz6728]

Best padlock I ever had. In the construction place where I work it's unbeaten. Working flawless with new app in 2020.

[@TheMechanicalPhilosopher]

[@zvpunry1971]

The channel hopping between 2.402 GHz and 2.480 GHz makes the communication absolutely resilient against farts (or other gaseous emissions)!

[@DrakkarCalethiel]

Great timing. Got home 2 minutes ago. Time for a good teardown!

[@CliveChamberlain946]

This is a refreshing change! A Canadian product at just $51 loony bucks (around 40 USD?) on the amazon-ca site. Masterlock is from Dudley Canada. Go figure, when you live under the shadow of the U.S.ofA, not too many of our products get any mention.

[@km5405]

and the motor has magnetic shielding too .... impressive, even if its a slightly stupid idea, its engineered well!

[@ChipGuy]

Finally the good old garage got used for the channel again :) Yay to old times.

[@Audio_Simon]

It would actually be good for my workshop as I go in and out a lot but get tired of entering the combo especially when dark. No outdoor use though!

[@brightquark]

I think the simplest weakness is the motor pins are on the edge, next to the plastic bushing. A hot soldering iron would put holes in the desired location and then just insert two wires from external battery to energise the motor bypassing the rest

[@andreccantin]

Is it protected against over-voltage (maybe 9V, since that's an easy battery to obtain and carry) on the external DC input? If 9V won't do it, how much voltage does it take before failing? I'd be worried about someone intentionally frying the electronics to lock you out.

[@LEGnewTube]

"Someone farts half way across the room and the Bluetooth connection doesn't work." 😂 😂

[@jfwfreo]

The real weakness with most of these Bluetooth smart locks (be they padlocks like this one, the kind that fits over the locking snib on a single-cylinder deadbolt or the kind that actually replaces the door lock on a door) is that the security involved in the communication with the lock is usually junk. Many smart locks have been hacked open without ever having legitimate access (there was a talk at a hacker conference about it IIRC).

[@diegoespinosa82]

Jonathan Wilson - True but depends on the software security app. Some come with key encryption making it difficult to hack. Key code

[@NamdeoPatil]

Thank you for the inputs

[@GPUtest]

Two times "Hi!" means this video will be two times better :)

[@TheChipmunk2008]

Anyone else see this in their recommended videos and have a "Wtf, Bill already did this one" moment... before the "ohhh it's Dave!" moment?

[@FreddericUnpenstein]

The level of thoughtless divisiveness here is astounding. If it was weatherproof, something like this would be perfect for my front gate; I walk to the shops for a bit of exercise if I only have a small amount of groceries to buy, and if I get a little too much, or it's started raining, fiddling with the gate padlock is a rite PITA. These locks have been found wanting, but I could write a book on the number of times this would have been useful in the past decade on my front gate alone, from the cleaner, to that adult kid who got kicked out of their home that you just don't trust with your keys (when you're kind of glad your wife list the spare keys, because it's actually safer to leave the house unlocked occasionally, than to give them the spares), to the friend you want to let in to feed your dogs because your car broke down and your going to be stuck in Woodenbong overnight (yes, is a real place, and it happened to me), etc., we've had it all. Not all of us live in a candy coated world where everything (and everyone) works as it should. I for one hope this technology matures quickly.

[@EEVblog]

They make a weatherproof version

[@DoRC]

This is probably master locks most secure lock since it doesn't rely on their marshmallow of a pin tumbler.

[@RygartARTB]

"somebody farts halfway across the room, bluetooth doesn't work". Love it.

[@leisergeist]

Master locks are a joke in the first place A beginner can pick their key locks with actual paper clips... Ask any locksmith what they think about them lol

[@Peter_S_]

I made that boast to somebody who challenged me to prove it, so with two jumbo size paper clips (one bent into a tension bar) I opened their Master padlock in less than two seconds from when the pick paperclip went into the keyway.

[@WacKEDmaN]

easy to push them locking pins in with some shims..im sure theres a vid floating around on youtube showing exactly how to do it

[@EEVblog]

No, I don't think shims will work on those pins. The bottom locking pin will prevent pushing down of the upper locking pin.

[@ConstantlyDamaged]

It's just a master lock. You tap them once or twice with a hammer and they will fall off on their own.

[@leisergeist]

Yeah, shims won't work on modern Master's, they've at *least* come that far. But their key locks are abysmal

[@agentsixsix]

Hey Dave, that's a double "Hi" at the beginning. This one becomes a collector's item, I think! 🤓

[@khronscave]

Just another case of "just because you can, doesn't mean you should"... This one's almost up there with the likes of Juicero (AvE hint) :P

[@apbosh1]

Had a break for a while but forgot how funny and good your videos are. HI

[@adityakhandkar2923]

Android has the inbuilt Bluetooth logger that stores captured packets in the log file. That file can be imported in Wireshark for analyzing which could potentially reveal the key code if it is not encrypted.

[@papal1ef]

Nice work Dave !!!

[@dangerousmythbuster]

Can't wait to see a Defcon video about this lock.

[@MrYoshiDan]

I'm having a difficult time even understanding this from a convenience standpoint. I mean, you reach into your pocket, pull your phone out, unlock your phone, open an app... How is it more convenient than reaching into your pocket, retrieving a key, inserting the key, turning the key? Is it supposed to be more convenient because you don't have to carry a key? I mean, you're already probably going to be carrying your house keys with you anyway, what's another key on your key ring?

[@johnfrancisdoe1563]

MrYoshiDan According to the video, you keep the phone in your pocket, and whenever you are close enough to the lock, it opens on the first keypress. Of cause that would require Bluetooth on at all times, even if not used for anything else.

[@yuppiehi]

This product simply taps into a market where people will use their smartphones for EVERYTHING. Don't look more into it - there's nothing there. This is simply an example of top-down marketing. Mr. Masterlock asked a bunch of millenials how to tap into the smartphone market but still stick to its primary business of selling padlocks. And this is what came out of the findings.

[@ian-c.01]

Yup, smartphones are making people dumber !

[@docgonzodotcom]

+Ian Clarke if a smart phone is so smart, why does it always connect to the weakest wifi access point around ? :)

[@MitsumaYT]

It has a "Locker Mode" which Dave missed in the beginning of the video and called it a "Fail" funnily enough. That does it as the advert in the front describes it. You don't have to touch your phone, it only needs to be in the proxmity of the lock to be able to unlock it. If you don't use that you have to use your phone to unlock it manually or the combination.

[@adamlumpkins2000]

Damn Dave! I have watched you for many years, and I have never seen you so pissed about a product. Lol

[@fpicotte]

The big advantage with these connected locks is access control. In our case we're a large student team (soon to be ~60) with small office space in the corner of a large multi-million-dollar university research lab. The University can't afford tracking and crafting keys to the lab for everyone, much less changing locks every time a student leaves the team or graduate. And updating everyone with new combinations is not much more of a hassle-free solution. With connected locks, you just edit people's access online. This was a good compromise with the University, going from 3 supervisors cleared for key access to our entire team. We're also planning to buy more for controlling access to equipment and hardware requiring special training.

[@LycanWitch]

Dave, you probably have to move the phone out of range then back in range (or just disable bluetooth on your phone then reenable it), then the lock may unlock via bluetooth. It makes since for it to remain locked while in range because it would be bad if it unlocked when you're in range then remains unlocked or keeps unlocking when you are attempting to lock it because your phone is still in range...

[@DoctorThe113]

3:38 I have seen some padlocks in my life and in my experience those which comes with a "hardened" marking on their shackle are not hardened at all, sometimes not even steel. I recommend you try cutting it with a hacksaw and see if it cuts or not.

[@FrankETaylor]

Great video Dave!

[@harshbarj]

I have never understood this fad of electronic locks. I have seen a ton come onto the market for bicycles. This is simply a solution looking for a problem. Most of the time when a lock is defeated, it's not the lock itself that is defeated, but the shackle. Most thieves use either bolt cutters, or an angle grinder. Why complicate things with an electronic device that will fail at some point far sooner than a mechanical lock.

[@RevJR]

Very neat! Wonder if Bosnian Bill will do a picking?

[@mgzukows]

He already did, atleast a similar one if i remember.

[@NathanaelNewton]

Rev JR yea it didn't last very long, check bosnian bill's video at 14:48 😂😂😂😂

[@npiper]

He looked at one but it barely qualifies as a paperweight by Bill's standards.

[@NathanaelNewton]

Echo_Hotel hahaha very true :)

[@towerclimber7277]

The lockpicking lawyer did a review too, both came to the same conclusion... Junk!

[@SproutyPottedPlant]

Use it to lock up David2 and see how long it takes him to escape.

[@EEVblog]

He knows you want to tie him up ;->

[@4pharaoh]

Thanks for the great excellent vid. But when it comes to cracking the lock, the correct tools start with a Bluetooth sniffer. (Which would be a good series for you to get into :-)

[@nikomo]

Funny bikes and sheds you Aussies have, we don't keep ours indoors. And the lock clearly states it's for indoor use only.

[@loic2665]

Double "Hi" ! :D

[@PunakiviAddikti]

The rotating bit that lets the wedge move down and let the lock open seems to be a Geneva drive. The motor rotates and turns it an exact degree every rotation.

[@jotchava]

Love this channel. oh man. Keep it up bud!

[@feynthefallen]

Dave, while you have that lock laying around, could you run 30V or so through that backup connector for us, just to see if it fries? That's the vandalism I'd worry about when having one of those where people can get at it.

[@footrotdog]

If you put it on your locker at school, I'm sure someone would just dunk it in a cup of water.

[@OliverUnderTheMoon]

0:42 Buys $100 padlock for locker; leaves $600 iPhone hanging out of backpack.

[@paultargett5211]

Dave, if you can punch through the plastic couldn't you tap direct into the motor wires to open it?

[@DrakkarCalethiel]

Someone farts halfway across the room and Bluetooth doesn't work xD Best reason ever!

[@EEVblog]

Because it's true!

[@VoidHalo]

Sure you can't take the battery out when it's locked. But there's nothing to stop you putting mains voltage across those battery terminals.

[@LucasHartmann]

Have you tried rotating the magnet parallel to the motor axis? I have seen some locks fail like that. Also DEFCON talks often feature padlocks from the electronic side of the problem.

[@EEVblog]

Yes I tried that. They get magnetically hack this at the CC hack conference, but mine seems immune to this, they might have fixed it.

[@Kek5kopF]

Interesting video, thanks!!

[@lezbriddon]

bosnianbill had a play with one of these... he loves the masterlock company...

[@vigneshnin]

I don't think it actually spins that much inside the lock. Its just a delay before the motor stops to ensure that the locking mechanism has locked completely... When it actually works, it will just rotate a little bit after which it will be stopped by that locking mechanism..

[@grndkntrl]

They do an outdoor version as well, which is model #4401. Not many favourable reviews of it on Amazon UK so far though.

[@gunnish1337]

"For bike or shed etc" The lock states "for indoor use only"

[@binaryguru]

Love the 'FAIL!' sign!

[@GearDownForWhat]

That tiny spinning piece is a Geneva drive. Maker muse did a video on those it was pretty cool

[@f304]

Hey Dave, What do you normally do with all the parts from your tear downs? Great video and you rock on The Amp Hour.

[@RobertSzasz]

The drive looks like a modified Geneva mechanism. In use the motor would turn 90° or so, it almost certainly just pulses the motor one way or the other for a moment to lock/unlock.

[@petresakov7955]

I know I am writing this a year later, but I would be curious to find out if it would be susceptible to circuit overload. Of course, if you run a high enough voltage through anything, it will release the magic smoke, but what I mean is transistors usually fail closed, so if the power rail is connected to the motor through a transistor, the transistor would fail closed way before the motor. In that case, you can just zap it with a high enough voltage, and you would be able to control the motor directly through the exposed contacts. I saw a fuse, but even with a fuse, transistors still tend to fail before the fuse fails.

[@richardgoebel226]

Once again good video, Dave. How many turns did the motor make? Was it a timed sequence? I only saw 2 power wires not any sensing wires.

[@RandyLott]

The life of a content creator. Re-take on the "Hi"!

[@darrenjacobson7456]

This is surprisingly well designed for a Masterlock. If only the bluetooth actually worked. Although, just as an electronic combination lock, it beats the pants off of any mechanical combination lock that Masterlock make.

[@mysticvirgo9318]

Doesn't look shimmable, either .. there is no spring loaded bit that engages the shackle locks is a solid mechanical mechanism.

[@EEVblog]

Yes, I can't see a way to shim this.

[@stonent]

For a second I thought I had a Bosnian Bill video showing up.

[@NoNameC68]

This wouldn't be that bad of a lock for lockers or when you're not trying to protect something insanely valuable. And, if there is someone who's used to picking locks open, this lock would probably throw them for a loop. I don't think it's that bad of a lock per se (depending on what you're using it for). When it works, it is less hassle than a normal lock, but normal locks aren't all that much hassle to begin with.

[@sarowie]

Indoor use only - well: That should prevent kids from tampering with your bike lock.

[@earlygrayce3200]

When I fart I block all bluetooth in my suburb, not just across the room.

[@ghammatx]

Those spikes you were measuring were from the power supply/battery? Are these dips in voltage due to the current spikes of the controller? If so, how comes that the bulk caps don't do their job and don't flatten these spikes? If not, than I don't get it :p

[@mozismobile]

Can't use it on a bike or most sheds, it's not water resistant. It says "INDOOR LOCK". So it's suitable for school lockers and that's about it.

[@jasonponciano6823]

Oh my we finally live in a world where even locks needs to be recharged

[@Fahnder99]

If i was to pick it, I'd melt the pvc with a hot knife and grab the motor wires.

[@zvpunry1971]

At least a good advertisement... people who have their phone sticking out of the backpack are exactly the right target group for that thing. ;)

[@TheBrokeHam]

Dave, check out the noke bluetooth lock, 1. it's not a masterlock so it's not absolute trash. 2. the bluetooth works pretty well

[@TheBrokeHam]

Also for me the usefulness of having a bluetooth lock being that if family or friend needs to get in to whatever I have locked up I open my app and send them an email. that being said even with my noke I have had the app and the lock miscommunicate and been locked out of about 10 minutes.

[@Chalky.]

The most I'd consider using this on is my work locker because it's unlikely anyone would bother breaking into it.

[@rikvdmark]

Ah the safe video, that was a good one! We've all been there in some form, the almighty "oops!"

[@MSgtBuzzKill]

I think it would be good for companies that need multiple people to get into. Like a job box or storage unit?

[@williamsquires3070]

Makes me wonder if this would be susceptible to a power-line analysis attack, given the two exposed terminals?

[@Cephalon_Shade]

The blutooth locks has some vulns in them i believe. I bet they still haven't been patched. Replay attacks would work too.

[@antwakefield]

3:05 - "Someone farts half way across the room and bluetooth doesn't work" - aussie as fuck.

[@kille78]

It's not like padlocks are solely meant to keep people out. They're more of a deterrent than anything. If someone is dead set on getting past one, they will. Boron or not, a pair of bolt cutters will get through real quick

[@janneaalto3956]

I think Bosnianbill also cracked this one some time ago.

[@jameskrivitsky9715]

Interesting tear-down Dave. What is to stop a thief from using a battery powered angle grinder with abrasive blade from cutting the hasp ? Not much ! I've heard of some folks who chain and lock gas power generators to a structure. An opportunist could plug in a grinder ( generator running would block the noise made by grinding ) and be off with the whole system ! It only slows the "honest " folks. J K

[@proluxelectronics7419]

The Masterlock Advert showed someone stealing TURF !!!!!!!!!

[@Novalight2550]

Fiddle with the external power input. Fuzz the crap out of it and see what happens.

[@davesage9190]

Do you think the plastic surround strip might be to let the Bluetooth signal out? Otherwise it might be fairly well shielded by the case - No?

[@markharvey18]

A little squirt of water to permanently lock it, and a little tap with a hammer to permanently unlock it.

[@bjornroesbeke]

I bet there's absolutely no encryption used between the lock and the phone.

[@markusofficial9016]

You could just drill a hole in the back just above the pinny thing in the middle and you're in. Should be reasonable in backyards etc.
