master combination locks, the school ones

by **cantpick4life** » 1 Jun 2004 8:04

im having a little trouble finding information on how to pick ( not find combination ) on the master locks that you use at school. i tried destroying mine to see how it works but the thing is indestructable, i tried using a hammer and flat head screw driver, i tried using a sledge hammer and all i got off was the dial that you turn

if anyone knows how to do it please send a PM to me or just post it.. thanks

you need to pull up on the shackle hard enough that the dial will still turn, but it will "stick" on some numbers as well. turn the dial right twice till you get back to zero. now pull up on the shackle as hard as you can. the dial will not turn, right? now ease up until you can turn the dial and turn right. the dial should stick on a number here in a second. if it is between numbers, then it is a fake point, and there should be seven of these. the remaining five (oh yeah, twelve in all) should be on numbers. four of those should have the same one's digit, those are fake. the last number is the third number in the combination. i've seen the first and second numbers found two ways: one, by adding five to the number to obtain another list of numbers that are to be the first number in the comb. and adding six to the last number you got earlier to get the second number. from here it is trial and error, but now you don't have 32 or 64 thousand combinations anymore, eh? this is also used for most masterlock combinations, search to make sure, and i'm using this information from a link i found on here, but i'm sorry i cannot remember where, but this isn't my idea or method, just something i use, and i thank and give credit to those who invented or discovered it

Please go sit in the corner until you look around a bit more. If it is a master padlock it is just a normal pin tumbler (or warded lock) and hence you just need to follow the rules for these locks. Do not worry about the brand or the make just make some tools, read up about lockpicking and try. Welcome and best of luck.

sorry about that, i just noticed that you mentioned something about NOT finding a combination. it must have been another post of yours

Oh didnt read the post correctly. Someone asked about master combo locks just a day ago. Give it a break and browse.

When I want to destroy a master combination, I usually lay it on its edge and swing at it with a sledge. The back is thin sheet metal and will bend and distort quite readily this way.

Have fun and try not to smash your fingers "picking" that lock.

These locks can be opened using padlock shims (the ones that sort of look like flying birds). Although the manufacturers usually say that such shims are for flat topped padlocks, not round combination locks.

Anyway, these shims will work, but it takes a bit of practice. Use a size A or B, just like you would on a regular padlock. However, it is very important to keep strong downward pressure on the shim, since the shim will tend to pop out because of the curved casing. Of course, insert the shim on the side of the shackle that has the latch... I believe is the left side, if you are looking at the dial.

As for taking apart these locks, it is extremely easy. All you need is a pair of needlenose pliars. Turn the lock so you're looking at the back. Firmly grip the edge of the casing where it folds over the backplate. Bend the casing away from the backplate. Go around the edge of the lock in this manner... it is rather like opening a can. Eventually, you'll be able to pull off the thin little back plate, and then pry off the thick back plate.

If you want to try this, go buy one that is colored: they come in all kinds of colors now, some with american flags and what not. For some reason, the casing on these seems softer than the plain steel ones.

if your talking about picking the small keyway on back it is real easy use a slimline typ pick and you may have to use ternsion at the top of the keyway where the pins are to make more room but they are very easy to pick

If it is a master/master clone then popcan shims work really well on them...

What you'll do is this
Grab a can of pop/soda/cola/coke/whateveryoucallitwhereyou'refrom
guzzle it down, get a pair of scissors and cut a small piece from the can, using caution not to cut your finger off on the popcan. About 1.5"x3/4" should do good. Now fold over the top 1/4" so you don't slice your finger when inserting it into the lock, cut the other edge in a curve like the bottom of a U, this makes it easier to get into a lock.

Now take the shim and wrap it around the shackle of the lock, the left side, if the dial is facing you, is the side you want to work on. I usually start by inserting the tip on the outside portion of the shackle and rotating it to the inside but you can start at either... I just think it is easier to get it inserted on the outside. anywho, once the shim is on the inside portion of the shackle, push it down inside the lock it can take a little bit of force but it will go, if you have problems with it, try pushing on the shackle, it seems to help me. anywho after you get the shim in, give the shackle a yank and it will open.

there is a video showing this, it was made by Jason Lynn, the link provided by lp101 is down, but someone asked for it a few days ago, I posted the link. Search for "Jason Lynn" or "Slower than Christmas" either one should bring it up.

I've yet to get these to work on any other type of padlock, the aluminum is just too soft to work.[quote][/quote]

Yo man, get a padlock shim. I have one and it takes me about 2 seconds to open most padlocks.

Breaking it open may be easiest back-first, as somebody here mentioned it's the thinnest/weakest part of the lock. There are techniques on these forums and links to help you open Master locks. Same goes for Dudley, except there's not as much help...

well i don't go any where nere combo's they're not my type of lock. the only ones i unlock are the ones with the emergency lockout protection pin tumbler lock at the back of the round bit they also can be annoying.

I don't see how it is so difficult, just bang at it til the back comes off.... I did that and used the dismantled lock to produce a master key for all the locks for a school in my town.

It is not hard at all to break open a Master Combination lock.
Just use some force, don't be a girl.

i just tested it today, using a carbon fibre cutting wheel on the back, if you know where all the junk is in there just turn on your dremel, throw a cutting disc on there and you cookin' with gas....
