(897) Review: Master Lock Bluetooth Smart Padlock (JUNK!) 

Masterlock should be ashamed putting this absolute garbage out at a level 8 security rating. People actually trust those ratings and they are being fooled by a company that clearly has zero concern with quality assurance. I hope they watch this, and do some SERIOUS reevaluation of their entire approach to the industry of "securing" valuables.

I think on master locks the security level is measured in seconds

You misunderstood, Bill: Master Lock level 8 security means that a child aged 8 can open it without supervision.

Well, the packaging DOES say "Never worry about a forgotten combination" .. Yeah, just bring a hammer. They weren't lying.

I have no clue how I ended here I’m not even into locks but for some reason you and the lockpicking lawyer guy are making me like this

up up down down left right left right B A start

First 14 minutes of me watching the video: "Oh my god, has masterlock actually made a good lock?" Hammer test: "Hahhahhah, nope"

lmao, Bill can manipulate locks from the inside with the greatest of finesse, but he can't close a battery door.

I really like the bit at the end where you discuss where it might and might not be suitable-something I find missing from a lot of "this sucks" reviews on RU-vid. In particular, any discussion of security is meaningless without a discussion of the threat model. Is your adversary a 12-year-old who wants to steal your $2 of lunch money? A curious neighbor? A bike thief? A meth'd out smash-and-grabber? A corrupt TSA agent? A skilled professional burglar? A government intelligence agency? A missile strike? A nuclear blast? In my opinion, a proper discussion of a security device indicates the types of threats it can and can't stop and how it compares to other devices that are similar either in price or protection profile. I think this review ticks those boxes. Kudos.

I do not know why Master Lock doesn't just send you a sample before they release a new model. They just keep getting embarrassed when you test them.

If that's level 8 security is the level 1 a Fisher Price plastic toy lock?

When they make a good body, they make a garbage core. When they make a good locking system or core, they make a garbage body.

"OMG, why would we test whether it can be destroyed with simple household tools like a hammer? It's a complex electronic device and there for being secure or anything!!" - engineers of Master Lock, probably. "Looks secure, let's rate it a 8/10!" - marketing department of Master Lock. Probably.

I was impressed with it right up to the hammer

Level 8 lock eh? What is a level 1? You give the lock a mean look and it pops under pressure?

Grinder: _grinding noises_ RU-vid captions: *[Applause] [Music]*

I was almost convinced ML made something worth having and then came the "HAMMER". Thank Bill.

Says it in the most calm voice ever let me go put out this fire

Bill: Unlocks high security locks. Battery case: damn this things is picky...

What if Bill is just a floating pair of hands?

Don't give masterlock too much credit for "water resistant." Simple circuits which are so low voltage, water isn't a good enough conductor to really bugger much up. Most electronics, as they come, are actually surprisingly water "resistant." Looking at the bubbles which came out every time you dunked it, it was clear the lock had really no resistance to water ingress, decorative rubberized cover or no.

This is an impressive lock, but the physical vulnerability makes it nothing but a gadget.

I think the timelapse would have been funnier if Bill steamed through like 30 easy locks

Wait wait, did master make something that worked as advertised? Hammer is suddenly introduced. There's the Master quality I expected.

Wow was actually thinking about buying this, but after watching the hammer test, I'm staying away. Thanks for the review!

I'm buying the lock he attempts to pick the whole video

laughed so hard when that lock popped open with the hammer. at least master lock is staying consistent with their skeleton key.

19 minutes later and Bill is still trying to pick that other lock ...

such a shame that master wasted a potentially good lock by being cheap on the casing

Wow. I wasn't expecting it to be so easy to hammer apart. Say what you will about Master Locks being easy to pick, but they usually seem pretty physically tough.

To really test for WATERPROOF, dip it in water with SALT

Can't believe this man only has 460k subs. Bill is a legend and I'm sure he doesn't remember me but a stand up guy on and off the internet.

Fire kills this lock though. I picked one up and ran a test of my own.

Busted in 3 licks with a regular hammer is a 4? I can't imagine what a 2 or something is then. Smack it with a wet sock?

Vulnerabilities aside, that's an awesome smart lock. I may grab one of these for my union steward locker. Just using a $2 masterlock combo lock because the boss isn't likely to bypass it, but it'd be nice to make it a bit tougher given the sensitivity of my notes. Pretty easy to shim or find the combination on the cheap combos, as you and LPL have shown. Keep up the good work Bill.

I have never picked a lock. I like watching videos about locks, though, and greatly enjoy your channel. My skills lie in software and computers. So when I see a lock like these, my first thought is that even if the locking mechanism is rock solid, I would bet money that the software is junk. Companies do not take software seriously. They do not approach it like any other kind of engineering, and since software is far more complex than almost any other kind of engineering, that results in absolutely terrible systems that are full of holes. I would love to see someone run WireShark and sniff the Bluetooth traffic (pretty sure WireShark supports that) and then try fuzzing the thing over Bluetooth. There is actually an online "game" for programmers/hackers called Microcorruption that is based on the idea of exactly locks like this, and you specially craft inputs to screw up the software and either dump out the key or just unlock the lock directly. If the locks weren't so expensive I'd probably pick one up just to play with and see how hard it would be to get into. Would be very interesting to see what signal, for instance, gets sent over bluetooth to the lock to tell it to disable locker mode. Since you don't have to disable that with the lock itself it appears, it is still actually listening to bluetooth, just not sending out an 'open request' when someone pushes its buttons. Wouldn't surprise me if you could make a universal 'disable locker mode' app. Or an app that just tries all possible keys. Hopefully it uses something better than a 16k keyspace on the bluetooth end of things...

5:12 "Man this thing is picky" I think you xould make a good pun out of that lol.

I wonder if you could activate the solenoid with a high powered magnet.

Have a very happy Retirement Bill. I found your videos many years ago while stumbling through youtube recommended videos. Though i never had any interest in lock picking I immediately found your videos fascinating and it opened my eyes to an issue that i often overlooked, and you did all of that while providing a lot of enjoyable entertainment. Though I'm sad to know that you won't be uploading videos anymore, I'm happy that you are doing that because you want to enjoy your life and your family. Have a good one. Cheers from Brazil.

I wonder if it's susceptible to powerline attacks. Brownout for example. If you drain the battery somehow and then use that port on the bottom to supply power, you can reduce the voltage so that the microchip can't function properly, and if you get lucky, code that runs the motor could be run. I've done this with a few simple electronic items before. By lowing the powering voltage you can get all sorts of crazy shit to happen. The most interesting things are when the device starts running code that shouldn't be able to be accessed.

When the music came I lost it 😂

I nearly wet myself. Opened with a hammer. Another Masterpiece!

I like your videos not because of your lock picking skills but your knowledge on all variety of locks and how to get pass them (realistically), just makes me think twice about buying these locks. Thank you

It would be very interesting to measure the voltage at those "battery dead" contacts. You could do a power analysis on it to see any peculiarities for good combinations vs bad combinations. You might be able to guess the combo like that if they have not enough bypass capacitors, or if they have bad coding practices.

Hi BB try an earth magnet onto the back of it.

Use salt water, conducts electricity

Good review Bill! My thoughts; The hasp is locked by the two cylinders, which in turn are held apart by the arrow shaped blocking piece. When the hasp/lock body is hit, the two cylinders will impart a force against the spring holding the blocking piece in the locked position due to it being angled....and the lock yields.. If the arrow had a stepped flat shoulder holding the cylinders in instead of an angle form there would be no imparted force against the spring. The angle of the blocking piece is it's Achilles Heel! Given that the lock body does not yield.

The silver lock that you picked while the Masterlock was under water is the real MVP in this video

Hey bill I have been a fan of your work for about 3 years, all the videos you make are educational, and are very fun to watch. I have been thinking about making a club at the college I'm attending now where I intend to show a lot of your videos and mainly help my community become a safer place. I was wondering if you have any inputs on how I could help people who have never done lock picking and if it is possible to help a lot of us understand more about the mechanics of a tumbler lock. I haven't spoken to the college yet about what I am planning on doing but I do want to have events like chaining up a bunch of locks and having two people compete in a race to see who can unlock the locks faster. And for more experienced lock pickers have them put the locks on the other persons chain. And who ever has fewer lock by the end of the time limit will gets prizes. I also hope it will be okay to use your videos. Thank you for the education and we will definitely stay safe and stay legal! 😄

Before I smashed it, I would have seen if over-voltaging the 9-volt connector would kill it.

You explain things like a teacher, i dig it

that response to the hammer was sad.

Holy shit, just caught a glimpse of bosnianbill 5:48

It's a pity. If they took this lock mechanism, which seems pretty solid by itself, and put it in a traditional Masterlock casing, it wouldn't be a half bad lock. The battery compartment wouldn't need to be in the secure portion of the casing, you could just run wires through where the keyhole would normally be, with the battery in a user openable compartment for easy access without becoming a weak spot. Just needs to be secure enough to stop some prankster from easily stealing the battery and giving you a bit of annoyance. One bypass for this sort of lock is if you could get a bit of wire in there and short the locking servo directly to the battery, but with plastic coated contacts for water resistance, and the fact that you'd be doing this through the tiny hole the wires for the battery go through, around a couple corners (no direct path between the hole and the part of the circuit board with the servo!), I think this would be near impossible to actually pull off. The button pad is also a vulnerability since drilling through it gives you direct access to the circuitry and the inside of the lock. But you could put it on its own miniature board on the outside of the secure portion and wire it into the inside through a little hole just like the battery. Then an attack on the buttons will just render the lock inoperable except by Bluetooth. But if you're going to be pulling out power tools like a drill anyway, it's questionable if this vulnerability is actually any faster than just cutting the chain or shank with a grinder. Properly made, a smart lock will offer just as much physical security as any good lock. Even a possibility vulnerability to a cyberattack, which is fairly easy for a half competent security programmer to prevent due to tiny surface area of the software, is fairly hard for a casual thief to exploit since it would be very dependant on the specific lock in question. On the other hand, if someone were to do a cyberattack, they could do it from their laptop while sitting on the bench ten feet away, thus performing the attack in public with no one being the wiser. But computer security is a well researched field, and provided you follow industry best practices, quite hard to crack, especially without the normal vulnerabilies of central servers with login information for everyone and weak passworks that can be brute forced with access to a user database breach. The lock's password is on a little piece of paper that comes with the lock, in the lock's memory, and on your phone, and that's it. And being a string of 15 or so random letters and digits, is not easy to crack.

Oh god, I sneezed right at the intro when the music stopped and thought I went deaf for a second

it never said it was hammer resistant

your intros are getting to crazy...

I like your channel and your thoughts on lock bypassing. You seem to think of it as a serious hobby. Even to the point of wanting to form a club of sorts around it. It is nice seeing someone with so much drive, and love for their subject of interest. I hope the best for you and your hobby. I'm only mildly interested in the subject. I still find your videos fascinating and entertaining though. You are a great voice for the subject.

I am new to lock picking,I have found all of your videos extremely fun!! thanks for doing what you do. this is a very fun hobby. also surprised on the 3 hammer hits.

I dont need to beat the encryption. Apparently I just need a hammer...

Always use salty water. It’s more efficient. PS: man, that fidget lock is nasty!

Very enjoyable vids, thanks a bunch for making them. But for the love of all that is great a glorious stopping zooming in so bloody far!

This was a really nice video. Not boring at all, the idle music was a nice touch.

5:48 would have been funny if Bill had a plant in front of his face like Wilson from "Home Improvement".

You should have put salt in water. It makes me way more conductive, so it should/may mess up way quicker and harder with electronic circuits !

When I was at the Base Exchange, a coupke days ago, I saw that one. And they had many different Mast lock options. For each different lock model, all had the same key code. So, if you have the same model number as your friend, your key will work on his lock.

Love the video. Two things: 1) I assume that the software is not open source, and therefore not available for audit. The reason I ask, we don't know if there are backdoors in the code - even just a reduction of the keyspace (most typical type of backdooring...) 2) Unless one looks at each chip inside, there could also be a hardware backdoor. Don't get me wrong, I'm actually thinking about getting one. Love the idea of a BLE lock. Would I appreciate someone doing the above two items, you bet. I wouldn't know where to start on either, I just know that these would give even more confidence in this product.

What is that padlock you were picking? The Abloy lookalike

Face reveal! first ive ever seen from you bill.

Very well made video! Most videos of this length seem to run out if material half way through

When doing a time lapse, you need an effective way to show that time is indeed passing. Ex. An open window, clock, hour glass, etc... It would add a nice touch to the video. Really enjoyed the review

Seems a bit pointless - I'd never remove it from "locker mode" for fear of getting within bluetooth range during the day, thus I'd always be entering the code, meaning it's now just a normal digital lock with bluetooth that's not being used.

The microwitches for the code entry system probably have a lifespan of 10,000 clicks. What happens when they die? Doubt that lock would enjoy being thermally stressed with a blow lamp or liquid nitrogen, either. Oh dear the pot metal / die cast zinc housing deadly tragic.

Good honest balanced comprehensive review. Now, is there a Bluetooth padlock that you would actually recommend?

I have to say, I had the indoor design of this. Classmates gave the battery compartment a good tug and it comes out.

If that is a 8, what is a 1?

I knew it was a masterlock but 3 whacks? good lord what a joke

Like how you called out the arm chair experts out on the blue tooth

Knowing Masterlock, I'm surprised the arrow code isn't the Konami Code! Edit: HOLY COW! That is a good lock. From Master Lock!

Is that a Trioving you're fiddling with to spend time? if so, saves me from sending you my little spawn of satan. very, very curious to see how you open it!

With a sledge almost every lock is junk... Or go full 2019 with the all new BL series angle grinders from Makita😂

Pretty cool design, minus the hammer weakness. Most of the time, if it says "water resistant" it generally refers to being in low pressure water. If you wanted to damage it with water, submerging it and pressurizing it would most certainly work. Did it have an IP rating listed anywhere? If it did, it would inform you as to how much pressure it would take.

We are about to go into the 22nd century and still bosnianbill can ruin master locks day!

Could you add the name & artist of the song in the description? A few of us are very curious.

I might point out that this lock isn't even sort of tough under fire, it was melted in about a minute by crazy russian hacker and a blowtorch.

I want the lock he was trying to pick while doing the time lapse.

Just drill through the front of the lock (where there is no metal housing) directly into the spot where the actuator blocks the shackle motion. In the video he said the actuator pulls down that arrowhead shaped bar but that is incorrect, that piece of metal on the actuator arm goes into the slot and blocks the arrowhead piece from moving down when the shackle is pulled up. Move the metal piece out of the way and the shackle can be pulled out. So drill that small piece of metal and force the shackle out. If you drilled a small hole in the backside of the case exactly where the actuator blocking metal piece sits I believe you could then force the actuator to rotate out of the way and open the lock. Since the hold would be behind the plastic housing you could remove the plastic, drill the small hole, open the lock, replace the housing and nobody would be the wiser. The plastic housing for the battery is directly next to the two wires used to power the actuator. Cutting out a section of the housing would give you access to those two wires which you could then use to cause the actuator to open. Since the battery covers where the hole would be, this also could done without anyone noticing.

"Lemme put this fire out." So nonchalant.

what is the music used during the water soaking sped up part?

Nice choice of music! Completed my little Bosnianbill Happy Dance a couple of times while I was waiting. :-)

the intro is unnecessarily epic

05:12 I see what you did there!

How to get in this thing quietly use a triangle file dead center between the shackle, use a flathead to depress the locking arm it's quiet, and should take less than 30 minutes

My guess for why it resisted the water so well is because usually water pressure needs to be higher to damage electronics like that. If you had put it on the bottom of the lake for about 30 seconds it might not be in such good shape.

Great video! I hope Master Lock saw it. They need to step up their game.

RU-vid wanna-be: "Oh yeah, I can totally hack that in seconds electronically." BosnianBill: "Video?" Wanna-be: *crickets*

would a magnet open this lock? i know alot of the electronic safes can be opened with a magnet because it activates the actuator.

Most things locks are on won’t be able to be moved over to a water source. I get it someone could bring a water source to the lock but they most likely would have to hold it there for awhile until the lock bugs out.

AT 10:00 who was watching the insect crawling to the left, instead of watching Bill pick the new lock :LOL:

3 licks with a common hammer. What a piece of garbage!
