Here’s any easy method for backing out the combination of a Master Lock. In a perfect world there would be 64,000 possible lock combinations (40 3). The construction of the lock prevents this from happening: sloppiness in the dial and the numbers are not mathematically independent. First step is to determine the last number in the sequence. You can then use that number to determine the other possible numbers in the combination. You will end up with about 100 combinations to try, but that’s far better than having to throw the lock out which I’m sure would happen if you had to try 64,000.
Welcome to the REVscene Automotive Forum forums. Can't open dudley combination lock. User Name: Remember Me? Password: Register: FAQ: Social Groups. To a school or institution. If it does belong to a school, chances are they will have the combo on file - match the serial number on lock. EDIT: Sometimes, if you pull on the lock, you.
For a Dudley lock, assume all numbers in the combination are a multiple of 3 (this is fair because of the size of the grooves). This cuts it down to 20 digits or 8000 combinations. If you use the above method, it cuts down the number of trials to about 400, and any Dudley I've ever had, the middle number is the lowest of the three. Dudley Lock Unlocker - By person66. While in most cases the second number on Dudley locks is smaller, there are a few where the second number is actually larger. This is what the 'Swap' and 'Show all' buttons are for. The 'Swap' button will switch back and forth between Large.
UPDATE: x04d sent in a video demo (DivX) (dead link) of how to open a lock in 2 sec. Using a padlock shim. UPDATE: The linked video above has long been dead.
Check out our for an embedded shimming video Posted in Post navigation. Just so everyone knows, I bought two brand new masterlocks today, name brand with the black dial.
Shim does not work, and I’m not suprised. Finding the 12 digit’s and eliminating 11 of them, then using modulo 4 to further get 100 combinations still works. I opened the new lock without looking at the combiniation in under 5 min. Then I opened another older lock my roomate had forgoton the combo for in about 8. (the combination was further down the list of possibilities that the first one.) One thing to remember is that most locks are made to be exploited, so a locksmith can unlock them if need be.

My best explanation is that the locks are not accurate down to the number. The algorithm would yield 21 and 25 (both of which are congruent to 33 mod 4), and it’s possible that 22 falls within the effective range – the room for error – of one of those values. Another consideration is that the given final value might not be quite right either – try to find the last value using the procedure as given, you might find it isn’t exactly 33. If it’s 35, for instance, that’s congruent to 23 mod 4. If it’s 34, then it’s congruent to 22 mod 4, and 22 could easily be in the same range as 23.
Anyhoo, that’s my best guess. I tried the method posted by strazzere, using shims made from the metal on a diskette. I got the lock open immediately. I used to do it the old fashioned way, by dialing the numbers, listening and pulling the hasp – that was never 100 percent accurate and took effort and time. This method so far has been 100 percent and never takes long.

PS – I used this for “good”. Students do things that they think are funny, like locking their combination lock onto other peoples property, which requires the bolt cutters to be found. This year THEY were the ones who would have to go look for a set of bolt cutters, to remove someone elses lock from the handle on their back pack.
Thank you for the new and improved version to pop a lock.:D Many kisses. This is the last time i will post this here so listen up.I can show you how to make a key to open all #175 master combo locks, (thats the brass thumbwheel type, NOT THE CHEAPER DIAL TYPE,that is used mostly in locker rooms.)Its really amazing how easy it isThis is NOT A SHIM TOOL.it is a very easy to make KEY that will open ALL #175 master combination locks faster than you can work the combination!!!this is your last chance to be the first to learn this trickI’ve looked all over the internet and have seen nothing on this hackE-MAIL ME FOR DETAILS. One way to test a bolt cutter before buying it would be, if you’re in a hardware store, they have a bolt cutter they use themselves to cut chain–some times it is a fixed machine type thing but sometimes it is just a boltcutter.
So ask them to look at their boltcutter and see if the jaws in particular are the same quality as the ones they sell. Ask if they cut case hardened chain with their cutter. And also just tell them you are buying this cutter for such and such a purpose and get them to assure you it will do the job.
Then if it doesn’t, you’ve got a good reason to bring it back (with the thing it won’t cut would be good) and get a refund. If they get tough the legal angle is they warranted it (represented it) (orally) to be useful for a particular purpose, you relied on their representation, and their warranty was breached.
