Crack Combination Lock Codes! No Code? No Problem!

hello again it's lock noob and today well i'm going to take you through every main technique that i know of to open up any dial combination padlock like this we will be looking at bypass techniques exploits and decoding techniques including shackle pull shackle push dealing with false gates and reverse decoding it's worth mentioning that all of these techniques are well documented and should definitely highlight the fact that for the most part combination locks should only be used in low security applications very few combination locks of this type are able to hold up against attacks like these for very long before we start let's very quickly remind ourselves about how these dial combination locks work some work in a slightly different way and will require a slightly different technique to open but they are all a variation of a theme where a locking mechanism is released through interaction of gates in the dials so with these dial locks of course you would turn the dials to the correct combination that will allow a path through this locking mechanism to allow the shackle to be released let's have a look at the inside of one of these to just see exactly what's going on if we open up one of these dial combination locks you can see all the parts that make it actually lock so there's the cover in here you'll usually find some kind of little spring which keeps tension on the dials and stops them rotating all about and may provide a small click sound then you have both the outer and inner wheels which can be disengaged so that you can move the outer wheel to a different number providing a different combination when you actually take out the whole locking mechanism here you can see that you actually have essentially two parts which come together to provide the locking and unlocking part of the lock you have teeth on the inside of the shackle here like this and they stick up and they have to pass through gates in these wheels so to allow the shackle to slide up these teeth must be able to pass through gaps in these inner wheels and you'll see there are two types of gap but there are ones which go all the way through these are true gates they will allow the teeth of the shackle to pass fully through then you have these little notches which do not go all the way through and these are called false gates and they're designed if you're trying to decode these locks to trap the teeth inside them like that so there's a false gate trap the teeth inside them and stop the shackle from being released but it will feel that you're in a true gate so the idea with all these decoding methods is you have to find the true gates in every single one of these inner wheels and of course the outer wheels can be disengaged like that turned to a new position then re-engaged with the wheel and that provides you with a new code and different mechanisms and different locks to allow that disengagement and re-engagement to provide that different code which of course line up with a different position for that true gate different padlock types will have a slightly different way of working but they all rely on some form of interaction between a wheel and a gate with the locking mechanism the first technique to talk about works on many many padlocks with this form factor with the dials on the bottom for many different manufacturers it doesn't matter what numbers you have in just scrambled it randomly what you need is a bypass tool like this with a blade reserve which is around seven thousandths of an inch or so and you gently push it down side of one of the wheels like this wiggle it underneath the locking mechanism which you'll lift up so it releases the shackle like that and it works on a number of different paddles from a number of different manufacturers here's another example again i can just randomly scramble these wheels up it doesn't matter all you do is take care in putting this tool down the side of the wheels until i can reach the locking mechanism at the back support it lift it up and with this one you should just depress the shackle a little bit and then we have an open there we go this tool can also be used to decode some locks where you don't have shielding between the wheels that allows you to feel for the flat spot which corresponds to where the locking mechanism falls into it doesn't correspond to the number that you dial in but there is a way to find that out so you gently put this down the side of the wheel and make sure you're touching the inner wheel and move this forwards and you'll see the angle of this change as you get to the right number so there the flat spot on seven this one flat spot on eight this one and it can be really easy to tell flat spots on zero plus what's on five now on most locks it's actually five positions away from that spot but not on all of them but on this i'll show you so just move this one five positions forwards so seven equals two eight equals three zero equals five and five of course equals zero on a ten dollar lock and we have the open some locks like this can't be decoded using a tool like this or bypassed they have a different locking mechanism one where you grab the mechanism using a notched tool like this which is very thin and you can go in down sides of the wheels pull on the mechanism and pull the mechanism towards the dials where you need to feel then for the true gate and you can do that quite easily and you can tell that you're there when you get them because this will happen you'll see the tool move and the dial move to see that so that on that last number that last dial will be pulled in by the tool and you have an open an absolute classic decoding method for these cable type blocks is to just pull on both sides and provide tension essentially you've got a row of teeth and what you're doing is you're moving the dials until you find the gate and then the teeth can move through the gates i'll show you that a bit more detail once we have a go decoding it so this is actually set to zero zero zero but the technique is to find the wheel which is binding the heaviest went under tension i think this one and turn it until you feel you can usually feel something move when it's in the true gate it'll move about but you won't be able to move it easily onwards next one can't feel anything on that one so go to the next binding gate wheel which must be this one this is binding quite strongly and yeah it won't move beyond that but it's in the gates let's try this one don't move them once we're in position and i felt that slot in and there we go oh that was quite violent now you can see the teeth there and you can see the gates on the inside by turning one of these dials you'll see them close off and then open up close off and open up same with all the dials all the way down all these zeros here correspond to the true gates and as you turn through you can see all those gates close up and open they go look at that the idea about pulling one part of a lock in this case the shackle against the locking mechanism in this case the wheels holds true for most padlocks of this form factor the more simple the padlock the easier the technique and the most simple technique is a symbol shackle pull find the binding wheel turn it that is the most stiff wheel in this case turn it until you feel the wheel go slightly looser and wobbly around a number that signifies a true gate then you find the next binding wheel and carry on so let's pull this really hard um and just have a that's loose this is quite tight and that's quite tight but i think this is the tightest so i'm going to go along with this and again see it was tight and now it's loose around this number which is the next this one's very tight now and again very loose now against that number zero so i imagine this is going to be zero zero zero now this wheel is very tight and we have an open that's really simple no false gates in this there's only one true gate per dial symbol shackle pull um feel for the wheel which is binding the most keep turning until you find the right number which case it'll go slightly looser and be able to rock a little bit around that number and then move to the next binding wheel keep going until you get the lock to open for some locks and it's usually more expensive ones but not always the case you have not only true gates which are nice deep cuts through the wheel to allow the shackle to pass through but false gates which are not cut all the way through but they are notches on the inside of the wheel to make you feel like you're in a true gate how do you get past that well you still need to find your binding wheel work forwards you pull the shackle you get yourself into what feels like a um a gate of some kind and there you go so all those sixes feel like they're some kind of gates but they're not um a true gate and the way you feel for a true gate is feel to see whether you've got a lot of movement where you got a full gap you tend to have a lot more slop in the in the wheels and this is rocking back and forth on that number and same with this one and this one but not by very much so release the shackle a little bit which you tend to need to do to get yourself out of a false gate turn say the top dial and move it to its next position along making sure that you keep yourself um in the false gates on the other dials and there we go so this number four is now the next false gate and it moves but it's still very stiff and only a little bit of movement so release the shackle tension move to the next position make sure which is two again little bits of movement but not too much i don't think that's a true gate move it to the next position again might need to depress the shackle to free up the wheel and ah that's a lot looser and you can see the movement there is greater as well it goes all the way from um almost the the next marker along and back so you should be able to feel here um a lot more movement around the true gate and then you just repeat that process all the way down moving along to the next binding wheel which happens to just be the next one down is that truegate no releases tension move along make sure you're still in your room no make sure you're still in your false gates and yes there we go much looser and you keep going and eventually you'll get all of your uh gates in a row and it'll open up and just to show again if i just put that into a false gate you'll see that these numbers here on the true case they wobble about a lot compared to the one in the false gate which is stiff and doesn't have as much movement so what you're doing in this method is you're trying to put every wheel into a gate or a false gate and you're feeling for when you're in a true gate on the binding wheel by the amount of movement the true gate will give you some padlocks with which are cheap and have false gates they can be very hard to read just due to how cheap and badly made they are so much so that you can not often tell whether you're in a true gate or a false gate or anything in between with this what i would do is i pull the shackle i'll get myself into what i think is some kind of gate or or something like that and then i i'll try to find what the binding wheel is which i think is the top one and i would turn it until i get into um a position which i think is either true gates or a false gate but i can't really tell so what i do is i feel for whether these wheels are changing if it's a true gate the tension from uh that's on this wheel will pass to the other two so what i'm doing is i'm reading to see whether this is in a true gate by whether these two remaining wheels change at all in response and they're still loose but that's a nice click that's loose oh but that's a lot tighter and again i'm looking for now as i turn this wheel whether this wheel um go stiffer and it's very stiff around this one so it's three something nine and now it's just a case of turning it until the shackle pops up there we go so it's another way of decoding you sort of do it in reverse you're not testing for a true gate on the dial that you're turning we're actually testing to see whether you're in a true gates by testing the other wheels to see whether you transfer attention to those two because you're now in a true gate on the one that is binding you might find yourself in a situation where you need to decode a padlock which is open but doesn't have the correct code in so you can't lock it and you just do the same thing you push the shack instead of pulling it this time find the binding wheel which is this one and turn it until you feel it jump into its gate go to the next binding wheel which is this one now and then the next one when they're all in the true gate and you should feel it there you go you should be able to then lock the lock back up and you know it's code which is in this case zero zero zero four some extra ordinarily badly made padlocks you can actually use a bobby pin to push down the side of the shackle down into the wheel pack and what you can then do is turn it and you should be able to find where the uh true gate is because it'll allow the bobby pin to slide down a bit further and hit the next wheel and turn it until it finds in the next hole which is the gate and then down and the next one and then down i will show you some footage of me doing exactly that probably sped up on a lock i no longer own [Music] so [Music] so there you go those are my top techniques for opening up dial combination padlocks now unless you have prior knowledge it's very hard to say which technique will work on which dial combination padlocks so there may be a little bit of experimentation you need to do but it is really really good fun practicing these techniques so i hope you have a lot of fun doing that if you like this video please leave a like if you have a comment please leave the
