- EquinnoxX, on 10/12/2007, -1/+991 ... 2 ... 3 .. 4... 5 ... ??!
That's AMAZING!! I've got the same combination on my luggage!! - diggnate, on 10/12/2007, -1/+69this is really cool.
by the way, if you're really bad at math, or just don't want to have to write it all out, I wrote a php program to do all the work for you. All you have to do is find the 5 whole numbers in the first step (his were 3, 13, 20, 23, 33) and put them in the text boxes. Then choose the one that ends in a different number than the others. the script does the rest 4 u.

It's not pretty, but it does the trick...
If anyone's interested, I'll post the source. - tooslickvan, on 10/12/2007, -3/+59This method does work. With a bit of practice, you can open any master combination lock in a couple minutes.
With lock picking tools you can open most locks in a few seconds.
Remember kids, locks keep honest people honest. - david76, on 10/12/2007, -0/+43This method should come in handy when I have a dream where I'm back in high school and can't remember my combination.
- robellis, on 10/12/2007, -2/+30He even says in the video that is for if you want to KNOW the combination not just break the ***** thing open.

The information I'm after is in someone else's safe, so I guess I'm still ok then. - inactive, on 10/12/2007, -1/+20I got it:
3rd: First, pull the lock tightly. Then turn the lock to the right until it gets stuck. Write down the number it gets stuck on. Release and continue all the way around. Circle all the whole numbers. Find the number with the last digit that is uncommon. That is the third.
1st: Divide the third number by four. Write down the remainder. Then add four to the remainder and write down that number. Continue until the number is too high for the lock. These numbers could be the second number.
2nd: If the remainder was 1 or 0, add 2 to it. If the remainder was 3 or 2, subtract two. Then take that final number, write it down, and add 4 to it until the number is too high for the lock. These numbers could be the 2nd number. - sahaskatta, on 10/12/2007, -0/+17Here is the full instructions + an Excel Spread Sheet which shows the possibilities.

Uh-HUH. - inactive, on 10/12/2007, -4/+18I agree, bult cutters make more sense to me. But if you want to keep the lock, or sneak into somthing without being caught that will work.
- RockSlice, on 10/12/2007, -1/+14Anyone else notice in the 3rd stage how he says what to do if the remainder is 0, 1, 3, or 4? What happened to 2, and how did you get a remainder of 4?
(and yes, I realize he meant "2 or 3", not "3 or 4") - ArveeOnFire, on 10/12/2007, -0/+12But we want to SAVE locks.
- NanoStuff, on 10/12/2007, -1/+12"This is intended for information purposes only"
I never understood what the point of such a phrase is. Ofcourse it's information only, that's what teaching someone to do something is, information; whether you intend they do something bad with that information or not, it's still just information. I think it would make more sense to say "Don't do anything illegal with the information provided" - darkmist, on 10/12/2007, -1/+11@JonBuddy
Ever noticed how you can miss a digit by a couple numbers and the lock still opens? If you take a look at the mechanism, there is actually some leeway (did I spell that right?) as to where you can get the correct combination. The lock doesn't actually have as any combinations as we think, they just mark numbers on the dial all the way up to 40 to make it appear like there is 10's of thousands of combinations. That's the principle behind this method. - dgh1973, on 10/12/2007, -2/+11Bully makes it look so much easier...
- mozzep, on 10/12/2007, -1/+9it's like 6 minutes long, I'm guessing you didn't graduate high school.
- Pottersquash, on 10/12/2007, -0/+8that would be admiting something illegal could be done with the information. Saying it is only intended for info purposes you make no statement as to the use. Why going on record admiting youve created something with criminal aspects if its not required, f
- JonBuddy, on 10/12/2007, -0/+7Yes, darkmist, thats why i said that the combo may actually be 6-8-22.

I think that was posted here on Digg once... - SenatorPenguin, on 10/12/2007, -0/+6It's much easier to use the shim to open it, shine a very bright light inside of it, and watch the the discs while spinning to get the exact combo, first try.
Cuts down on the guess and check, and it only took me about 2 minutes. - rnelsonee, on 10/12/2007, -0/+6I learned this over the summer and it worked on a new Masterlock I picked up in the store. His math could be simpler, but hey, it works. I'm posting because you can cut the trial and error phase in half if you know how the locks work.
Don't re-spin the lock for every new try - the first disc stays in place as long as you don't go back all the way around. If your first numbers are 0, 4, 8... the second set is always the first set + 2 (mod 4), so it's 2, 6, 10... Say the 3rd number is, oh, 32.
Try 0-2-32. If that doesn't work, just spin back to 6, then try 32. Then spin back to 10 and then to 32. The first number's disc is still in place. Now, this will work until your second number gets up to 32. Now you can start re-spinning, until you get to trying 4 as your first number (4-2-32, x-6-32, x-10-32), or you can go one step further:
If your 3rd number is 32, start your second number at the one right above it (which will be 3rd number + 2). So you'll do 0-34-32, x-38-32, x-2-32, x-6-32, x-10-32.... Then you only need to respin when you get thorugh all the 0's.
To - JonBuddy, on 10/12/2007, -0/+6Here are the notes that i took while watching the video.
Step One- Put tension on the lock and spin it around. Record the numbers that it sticks on. There should be 12. Five of them should be whole numbers. Write these whole numbers down. Four of them should end in the same number. The one that doesn't end in this number is the third number in the combination!
Step Two- Take the third number in the combination and divide it by four. It should have a remainder of either 0, 1, 2, or 3. Now, add four to your remainder until you reach the last number on the lock (usually 39). You will get ten different numbers. Any of these could be the first number.
Step Three- If the remainder was a 0 or a 1, add two to that number (0=2 and 1=3) If the remainder was a 2 or a 3, subtract two from that number (2=0 and 3=1). Now, take the remainder from before, run it though the equations in parenthesis, and add four to it. Keep adding four all the way until you reach 39. You will get 10 numbers. Any of these numbers could be the second number in the combination.
Now, run all of the 100 possible combinations through the lock. It should open with one of them. - sykotic, on 10/12/2007, -1/+6Cool code, but why don't you determine the last number automatically? that would be easy.
- diggnate, on 10/12/2007, -0/+5Sorry it took so long to get back to ya...
Here's the source, feel free to optimize, and sorry about the lack of comments, I did this quick and dirty:
http://nrcharles.com/masterlockpick/code.txt - MSTK, on 10/12/2007, -1/+6Yes, because I'm sure that if you don't have a calculator on you, you'll be carrying around a laptop with wireless internet.
- redbaron122, on 10/12/2007, -1/+6tried this on my friend lock got into his locker and left a little suprise
- maci01, on 10/12/2007, -2/+7Because that doesn't defeat the purpose..
- usbserial, on 10/12/2007, -0/+5Not if your goal is to steal the lock! Bwhaha.
- DanSheldon, on 10/12/2007, -1/+6IT'S A TRAP!!
- burningpenguin, on 10/12/2007, -1/+5Entertaining to watch and makes you think about how this device has been constructed.
- usbserial, on 10/12/2007, -1/+4I believe it's called "covering your ass".
- SenatorPenguin, on 10/12/2007, -0/+4If you are going to open it only once, then you might as well use a shim and not need to carry around massive bolt cutters. This video is closer to picking a lock, you are talking about bypassing it.
- bliz, on 10/12/2007, -0/+3for some number locks, they have a tolerance for +-1 for each number, meaning that 20-15-5 can work for 19-16-6 sometimes.
- Dylan16807, on 10/12/2007, -0/+38-10-20 seems a good fit. I believe in the all-powerfull equation.
- bobandshawn, on 10/12/2007, -1/+4Very nice for the purist...although EXTRAORDINARILY complicated...more of a parlor trick. A master lock can be shimmed in about three seconds if you just want it open.
- chasealicious11, on 10/12/2007, -0/+3This really helped me...
Write down the upper and lower bounds of the sticking point. While continuing to apply tension to the shackle, turn the dial as far left as you can. Make note of where it stops. Then turn it as far to the right as possible, and note that stopping point. Sometimes the bounds will be right on the numbers, but sometimes they will be between the numbers. On a piece of paper record the upper and lower limits as decimals estimated to the tenths place (for example, “36.3 to 37.1”). The difference between the numbers should be anywhere from 0.5 to 1.2. Note that the sticking “point” is really a sticking “range”.
Look at your list of sticking points and eliminate all those which do not contain a whole number (also called an “integer”) between the upper and lower limits. You should eliminate 7 of the 12 numbers with this step.
* A whole number is one that has requires no decimal point. 35, for example, is a whole number, while 35.3 is not.
* Ignore the endpoints. A sticking point with a lower limit of 35 and an upper limit of 36 does not contain a whole number (35 and 36 are whole numbers, but as they are the endpoints they are not “contained” within the sticking point. - nexah3, on 10/12/2007, -0/+3Nice, I just figured out the combos to two locks that I forgot the combinations for.
- spongy, on 10/12/2007, -0/+3"if your remainder was a 3 or a 4 subtract 2 to that number."
Should be
"if your remainder was a 2 or a 3 subtract 2 from that number."
If you divide the number by 4, you can't have a remainder of 4. Don't feel too bad he messed it up in the video. - foolfromhell, on 10/12/2007, -0/+3This has got to be fastest Dugg story ever.
Even though its a dupe,
it has 1600+ Diggs in 23 minutes! - Caio, on 10/12/2007, -0/+2This is what I got from the video... at least the number 20 works.

source code: http://www.neatcode.org/lock.html - Husky217, on 10/12/2007, -0/+2That's because it stays 2 ;)
I got remainder 2 with my lock, and it worked out. - blankman, on 10/12/2007, -0/+2he never says what to add or subtract if you get a 2 as a remainder
- Evilmonkee, on 10/12/2007, -0/+2He really makes it out to be more complicated than it is, math wise.
First, you don't need to worry about the places where the point rocks between two numbers. Once you find two numbers that share the same last number(ie. 3, 13) you can mentally eliminate all of them. You are looking for the only other whole number that is unique.
Secondly, if the 3rd number in the combo is even or odd, then the 1st and 2nd number will also both be even or odd, respectively(ie. 6/12/28, 3/9/25).
Knowing this, just create your two tables depending on if your numbers are odd or even. Start with 0/2 or 1/3, always increasing the next number by 4 in each table. - patrarno, on 10/12/2007, -0/+2ihacked.com has an excellent tutorial on making a beer can shim. I was able make it, and use it successfully on the first try, which took me less than 5 min to make. If you really want to baffle the target, put a combo lock of the same color/ brand in the place of the lock you've shimmed. They won't understand why their combo doesn't work. It will also lengthen the discovery of theft time.
- poet_will, on 10/12/2007, -0/+2I can't even see the video with Firefox 2 in Ubuntu.. maybe I'm doing something wrong, but Youtube works fine..
- rnelsonee, on 10/12/2007, -0/+2The way I learned recently was this:
Write down the 3rd number. Add four to it 10 times mod 40 (so just wrap around 36 -> 0 -> 4). That's your first list.
Add 2 to every number in the first list. This is your second list. No remainder crap necessary. - jupiterskunk, on 10/12/2007, -0/+2I wonder how long it took someone (whether it was this guy or not) to figure this out.
