Used your "Crack Master Combo Locks in 8 Combos or Less" page to open my daughter's old middle school lock she wanted to take to college with her but for which she had long since forgotten the combination. Worked like a charm :-)

[@Dracokhi]

Excellent video, very cool concept. I just had to mention that you repeatedly used the term 'Mils' to refer to millimeters . A mil is actually a different measurement: a thousandth of an inch (appox 0.0254 of a mm). Just wanted to clear that up and prevent any confusion!

[@timjohnson3649]

I'm in the process of building this. I don't have a 3D printer so i made the part that attaches to the dial and stepper out of epoxy using a mold. The part that holds the lock and case i made out of sheet metal. So far i am able to tell it what combination to try and it opens the lock. It sometimes misses steps but i have yet to incorporate the optical encoder into the system to create a closed loop environment. The servo i have didn't have the power and had plastic gears and ended up breaking the internal pot. I have another on order with twice the power that i'll modify for analog feedback. Then just a matter of programming out the kinks and this baby should work pretty consistently. Shout out to Sammy! You da MAN

[@DerrickAD]

Samy, This looks like a fun build. I'm looking for the video specifically on the more advanced version that you talk about at the end but I can't find it. Was it taken down for some reason, or perhaps never completed, or maybe I'm just not looking in the right place? Can you link to it?

[@StephenPaulTroup]

Did you make it? I would buy one if it works and can work on a lock that is attached to a locker. This is on the up & up. I bought a bunch of lockers with combo locks attached and need them off.

[@andrewking9271]

Funny thing is, this is faster than the lock breaker in the Battlefield Hardline campaign

[@lanyusea]

Hi Samy, I have one simple question. I watched your previous two videos and found you need to find the lock/resistance positions before trying all possible combination. But in this video I found you just using Arduino solving the combination part. Does it mean you still need to find the lock/resistance position by hand? Thanks.

[@CameronCobb]

I’m pretty sure this video is fake

[@marksstudio]

Very enjoyable. Plus a real treat to watch. Screen within a screen works well. Keep it up man.

Very cool. Unfortunately it looks like Samy moved on and didn't actually do the next video with the Advanced Combo Breaker.

[@tomelner]

instead of worrying about 3d printing you could use polymorph.It won't look as pretty but would get the job done. If you did want to stop a DC motor running you could active brake it by shorting the contacts... easily done with a relay. But the stepper motor was definitely the better solution.

[@MitchellRoseFilms]

He's awfully cheerful for someone instructing you in how to steal stuff.

[@samykamkar]

Mitchell Rose Films I get pretty cheery when presented with the opportunity to steal dirty gym shorts.

[@pagliacciocattivo1047]

Samy Kamkar What about breaking into peoples garages and stealing there expensive tools tools?

[@samykamkar]

Pagliaccio Cattivo Hi there, part of the idea here is to let the public know that these locks *are* insecure, and you should be using a higher grade lock if you are trying to protect valuables. There have been exploits for this type of combination lock for many years but most people haven't known, so hopefully this raise some awareness.

[@MitchellRoseFilms]

Samy Kamkar It might raise awareness amongst the Master people, but it would take many months to redesign and retool. In the meantime, people everywhere are at risk. Storage units, garages, basements, gyms, etc. And obviously every single Master lock owner isn't going to see this video. But many creeps will actually follow your plans and can go on the rampage. If your desire is to raise awareness, why not just send a proof of concept video demonstrating what your device does and send it to Master and news outlets and say that in one year you'll publish design specs on how to make one.

[@MitchellRoseFilms]

Samy Kamkar You can't seriously believe that all Master locks protect is dirty gym shorts. Even in the gym locker scenario, at the minimum someone's wallet is going to be in there. That means money, credit cards, drivers license, i.e. identity theft. If it was gym shorts that were at risk, I couldn't care less. But people use a lock to protect things they value.

[@Boki_D-dt9fi]

Will a battery powered drill work for the motor?

[@MichaelBerthelsen]

Boki_D 1275 No, the sensitivity isn't detailed enough to do it, and you wouldn't be able to read position to the chip so you can unlock it.

[@samykamkar]

It IS detailed enough -- the rotary encoder measure 300 positions per rotation

Any idea when the second video on how to build combo breaker will be out. One of my students bought all the parts and we have 3d printed all the pieces. We have assembled and programmed it.

[@kirasmith1147]

Garrett Day it exploits a vulnerability in combination locks that lets you crack it easily if you know the trick. This device just does it fast and perfectly

[@David24XD]

[@kirasmith1147]

This was really cool By the way what song was playing in the background?

[@samykamkar]

+fera acedia Thanks! It's an unreleased song from soundcloud.com/epochrises

[@aidangomez4726]

Great idea. The real problem with both the continous rotation servo and the dc motor is that there is no fine control of degrees, making it hard to automate turning to specific points on the lock. the continous rotation servo actually will stop when it's value is set to "0" because of the gears. You're right, a stepper is the best option. you get 360° turning and the ability to measure your turn "location" in steps. if I were to build this is would eliminate the servo arm and house it in a sleeker cylinder style case and add an led to indicate when the user should test the lock, speeding it up. very nice job man

[@kamarilabs5616]

Sammy, you tha man! Would this work on a fairly well made safe theoretically? I understand the electronics but Im not sure of the capabilities of your brute force algorithm. Is it limited to simple locks?

[@samykamkar]

Tim Matheson Thanks! The code is actually split up pretty cleanly so that you can apply it to virtually any combination-based lock. You would of course have to alter the frame and how it connects, and in this video I'm exploiting a weakness in Master combo locks, but virtually everything can be extended to any type of combo lock with a standard, but automated, brute force attack.

[@AndXorK]

Samy Kamkar Great project!!

[@shawnbarnhart4553]

Tim Matheson I think the value of this hack depends a lot on the weakness in Master Locks. A 100 position S&G dial lock on a typical gun-type safe has just short of a million possible combinations. The Gizmodo article I saw said this machine can do two combinations per second. Most better locks require a spin or two counter-clockwise to "clear' the lock for opening, so if we add that in for a total of four seconds per attempt, a full brute force could take up to 45 days. The other limitation would be how you know the safe is unlocked. A lot of S&G dials have a final 1/4 turn of the lock counter-clockwise that stops the dial and indicates the lock is open and that the bolt can be turned. I have a early 20th century railroad safe with a dial that doesn't provide any mechanical feedback the lock is open, you have to turn the bolt lever by hand. You could expand the apparatus to do this, too, but your device becomes more complex and more time consuming -- each second added to an attempt on a 100 position dial adds 11 *days* to your brute force window. Other complications would include dials with a key lock, secondary key locks on bolts, four-number combinations (time expands to 12 years) Perhaps useful if you have unlimited access to the safe -- ie, you owned it and were trying to recover a lost combination. Fun but less practical than a couple hours of a locksmith's time. Still, it would be interesting to see one built and used against common 3 digit gun safe locks to see how long it actually took to open them. 45 days assumes the last combo tried is successful, the actual combination is less and successfully opening several may indicate patterns that could speed opening. And then there's looking for weaknesses in the mechanism that may cut brute force time significantly.

[@cripion1019]

Absolute genius keep it up man

[@samykamkar]

+Cripion101 Thanks!

[@rich1051414]

You could tape a tube to the dial and mold a resin negative of the dial. It would break free from the dial after drying easily, then you could trim it and drill a hole to mount to the stepper. Seems like the most straight forward way to make a 'key' to turn the combo.

[@jeradw7420]

Or just put a glob of molding putty (you can make your own out of silicone caulk and baby powder). Then you can mold resin knobs all you want.

[@timjohnson3649]

First attempt and the mold got stuck. I used baby powder for a release but that sucker was on there good. I ended up getting physical with it and broke the bold. Going to try molding putty for the next one.

[@jeradw7420]

It took me several tries to mix the right amount of powder to silicone, but it does work. Too little powder and the silicone sticks too well. Too much powder and it won't take the shape you want. I put a pile of powder on wax paper and squeezed silicone on top. I used a wooden stick to stir. It was more like kneading bread dough (there are plenty of videos that show that technique).

[@Jsl1der]

How much would it cost for you to make one and just ship it? I'd be willing to buy one.

[@FishSnackems]

Kiwi Gaming 1 Dollar??

[@sterlingdeye5660]

love the concept but would you have a wiring diagram or some details regarding component layout?

[@samykamkar]

Sterling Deye Haven't had a chance to document the schematic but it's primarily the servo motor connected to the Arduino, stepper motor connected to the stepper motor driver connected to the Arduino, and a 5V voltage regulator to power things -- might not be necessary but didn't know how much current the servo would pull. The pinout is mostly in the code.

Hello Mr. Kamkar great video. Would you recommend Autodesk Fusion 360 or Autodesk Inventor (not to be confused with Autodesk Inventor Fusion, which is no longer available)? Autodesk Fusion 360 seems to be more user friendly and consumes lower system resources, but seems to lacks some capabilities of Autodesk Inventor (ex. Certain parametric capabilities, sheet metal design...). On the other hand, Autodesk Inventor seems to be a more powerful tool, but seems more complex and less "modern". Overall which of the two software packages would you recommend, or would you recommend a different CAD tool entirely?
