This is Why Combination Locks are Completely Useless

this week i wanted to learn how to crack a bunch of combination locks and then i even tried blindfolded why because a few months ago i lost all my trust in keylocks when i realized how easy it is to pick them even using paperclips luckily i was pretty sure combination locks were totally safe so really had nothing to worry about until youtube one day recommended a video about cracking a combination lock here we go again after a quick research to understand how combination lock actually works i realized that there are these different locks share basically the same mechanism this is the shackle and if you could see inside the lock you will see that it has 4 teeth corresponding with one of each dials each dial has an external disc with the numbers on it and an internal wheel there is responsible for locking or unlocking the shackle each one of these inner wrist has a small gap at some point when you set the right combination all the gaps of the four wheels are aligned allowing the shackle and its seat to slide through freely and opening the lock i decided to start from the cheapest lock then moving my way up to the most expensive and hopefully safer ones first i set a new combination without looking at it so that i actually had no idea how to open the lock following the theory we should pull the shackle basically all the time and apply pressure against the body of the lock then we test each wheel to find the hardest one to turn in this case it is clearly this one now you need to turn the dial until you can clearly hear a click sound and you feel the shackle moving a little bit after repeating the exact same process for all the wheels i wasn't expecting it work but it actually worked it is scary how easy it is or maybe it's just because it was the cheapest lock the story should be different for the bike lock it costs 15 and it's literally the one i bought to secure my beloved bike i honestly hope this won't work to set a new combination you simply need to insert the right one turn this dial and then start a new one and i did that without looking at the lock i tried the same method i used for the previous lock putting tension to the lock like if you are trying to open it and then i try to find the hardest wheel to turn but this time i couldn't hear any movement or sound so the first method wasn't working but luckily or unfortunately i found another method it's called indirect method like the first strategy we pull the lock but this time we start turning the first or last ayah depending on which one of them is the hardest to move this method consists in trying each number of the first style until we find the one that makes the next dial bind or simply hard to turn so starting from the first dial i tried all the numbers moving the second dial at each other and when i tried the number four the second dial was significantly harder to turn than before so the number four is probably the right answer i repeated the same exact process for all the other dials until i arrived to the second last one this is harder but it doesn't work so then i set the number seven and i started simply trying every single number until this happened no way one more lock i can't trust now the last category before trying the most expensive lock includes these two guys the disclock is really heavy and it gives me a nice sense of security but even if the shape is pretty different the concept doesn't change at all when you insert the right combination you need to push this lever and the lock will open i set a new combination without looking and then i started trying the first method of the ship lock didn't work i couldn't hear or feel any particular click so i decided to try the indirect method even for this one in this case you need to apply constant pressure on this level and by starting from the first dial you need to repeat exactly the same process i used for the bike lock and when you find the right number in a certain dial the next dial gets harder to turn after a few minutes i was pretty sure about the first two numbers i think it's five and nine now the last one at this point i simply tried all the numbers of the third dial and after a total of about four minutes let's go let's go it's insane how easy it is like this guy is massive but weak because of the shape of this lock it's pretty hard to turn the dials but all your friendly thief needs to solve that problem is a simple screwdriver this makes turning the dyes so much easier and so i wanted to know how long it was gonna take me to crack the lock like this it's zero one eight i'm pretty sure about it and i'm gonna show you all the combinations in the last style like all the numbers until yeah two minutes to open this massive log it is literally useless for the other lock of the sim category the story is absolutely identical pull in the shackle and move one dial at a time checking the feedback on the next style and in one minute and 50 seconds i've been able to open the lock now i finally wanted to see if i could crack a good lock this one costs around 30 dollars and it has a bunch of great reviews i tried the first method i used on the chip lock and it didn't work so then i tried the indirect method this one worked with the bike lock and the other two but it wasn't working i literally can't move this wheel anymore and neither this one the dials were getting stuck every single time for some reason and i literally couldn't move them as long as i can't pull in the shackles is this really the impossible luck to crack i would have been kinda happy about that honestly but the answer is no this lock simply has a fast gate mechanism this means that the inner wheels not only have the gap that allows the shackle to slide but they also have false gaps in which the teeth of the shackle can fall blocking the wheels without unlocking the lock and after a few minutes i was pretty sure i found the method to crack it like the other methods we need to pull the shock hole but this time you need to turn all the wheels simultaneously until they stop and you feel the shackle loosening a little bit this means that all the feet of the shackle are inside the gates true or false the second thing to do is checking all the wheels one by one while pulling the shackle and the ones that are harder to turn are probably first case in this case the second dial was really hard so i started with that one i started by releasing the tension on the shackle and turn the dial of two numbers and that's because in this lock there are four skates every two numbers then by pulling the shackle again if the dial is still hard to turn it means that it's still a fast gate it's just a matter of time trying 2x2 until the dyer finally can move loosely which means you maybe found a true gate after that you simply need to repeat the same process for all the dials until they can move loosely so i kept doing it over and over again and it's not easy because you need to test all the wheels every single time you lock one of them but after seven minutes the lock was open for the second attempt i wanted to time the process so i said it before i set a new combination without looking and i started trying it's been weird when i thought i was close at first i wasn't but then i kept trying and after a while i started to feel the shackle moving loosely and then five minutes to open the best luck i had my trusty locks at this point was completely lost but i wanted to see if i could actually humiliate them i wanted to know if it was actually possible to find the right combination of my most expensive lock blindfolded so i set a new combination and the lock is closed let's see first i'm gonna block the dials all right got it at first i thought i was making progress i think i'm getting close but i'm not sure but after a while i lost track of the position of the dyes and 10 minutes later i quit then i tried again focusing on being gentle and moving one single dial at a time and i thought i was close while i really wasn't and unfortunately even this time second attempt failed this is going to work now in the beginning i felt pretty lost once again they they keep changing like i fix one and then the others change but i kept trying being as gentle as possible come on i feel like it's a shackle is moving i thought it was really close and then this happened yes yes let's go [Music] let's go five five nine two and it took me about 30 minutes to make sure there wasn't just a fluke i tried one more time the key here is trying to be as precise and calm as possible keeping everything under control i knew the last three days were in the right position so i started moving the first style 2x2 yes let's go this was quick it took me 8 minutes and 57 seconds this time this channel is all about learning new skills and if you made it to this point in the video make sure to check out more videos subscribe and click the bell to not miss
