Combination Lock Picking
INTRODUCTION
Hey, want to learn how to decode those combination Master Locks commonly used in high schools? Of course you do, well I’m going to tell you. Aren’t I just the nicest person you know? If you answered “yes” then you are correct and may read on, otherwise if you read on I assure you that you will die a horrible and strange death a short time after reading this.
Combination locks are the locks that have the dial on the face of them. The name "combination" lock is a foul name for the Master Lock co. to call it because it is not a combination that opens the lock. A combination is a set of numbers, for example the combination 12, 3, 32 and 32, 12, 3 is the same combination, but only the right order of the numbers will open the "combination" lock. A much better name should be a “code” lock, this satisfies the fact that you have to know the order of the numbers as well as the numbers themselves. Nonetheless, I will be referring to it as a combination lock.
The way to figure out the combination is by process of elimination. Although you will eventually get the combination if you go through each one at a time, this will take you way too long and there is a much easier way.
But Omnidan, what can I do with this power that you are about to give me? Well, you can surprise someone on their birthday with balloons or whatever. Rig a nuclear bomb to someone’s locker and blow them up along with a nice chunk of the school. Any combination lock you find you can use; if you find one on the ground keep it, or if you find one that a bully uses on his locker, keep it and make them have to buy a new lock every week. Forget your combination? Who cares, you can now get the damn thing open no problem. Oh no, Christmas vacation just ended and all those girls (or guys) forgot their combo, be their savior. Some jerk pushes you in the mud, it would be pretty funny if he found his locker completely filled with mud wouldn’t it? Collect locks figure out the combination and sell them for cheaper than the school does. Be creative, have fun and most importantly don’t blame me, but you can tell me all about it. Alright no more BS, lets get to it.
THE LESSON BEGINS
Three Easy Steps to Master Lock co. Combination Lock Picking
THE FIRST STEP is to figure out the last number.
This is very easy to do. If you pull on the lock (pulling the U shaped part form the dial) and hold it, you will find that turning the dial has become difficult if not impossible depending on how hard you are pulling. The reason for this is because there is a ring that the dial is connected to. This ring has exactly twelve pits; one of which is really deep and is the last number.
Pull on the U part of the lock and hold it. Move the dial until it gets stuck, this is one of the pits. Ease up on the U part and move the dial in either direction about one and a half spaces; you should be out of the pit now. Again pull on the U part and continue moving the dial, very soon you will fall into the next pit.
Now here is how to figure out which one of the twelve pits is the last number. For your first time it’s good to take a note of where the pits are; make sure you are specific on exactly where it is on the dial. Here is an example:
1.5, 5, 8.5, 11.5, 15, 18.5, 21.5, 25, 28.5, 32, 35, 38.5
Numbers that fall between numbers are given a half: example between 1 and 2 is called 1.5
Here is how to eliminate which numbers are not the last number. It would be silly to have a last number that was not a whole number; I have never see a lock combination where the last number ended in a point five. So we can conclude that all the pits that are between numbers cannot be the last number. We are left with five numbers
From forty possibilities we went to twelve and now we have five. The five numbers that are left will have four numbers with the same number in the one’s place. In this case it is 5, 15, 25, and 35. All of these numbers are not the last number. In this case we are left with the number 32 as our last number.
THE SECOND STEP is to know the possibilities for the first and second numbers.
The possibilities for the first number are pretty simple to find. All you have to do is take the last number and add or subtract four to until you have all the numbers around the whole dial. If the last number is 3, then the first number could be 3, or 3+4, or 3+4+4. All ten numbers are each four numbers apart. Example:
First number combinations are: 3, 3+4 which equals 7, 7+4 is 11, 11+4 is 15…and so on all around the dial
We get 3, 7, 11, 15, 19, 23, 27, 31, 35, and 39.
The second number is no different, but they are between the first number numbers. Take all the possible numbers for the first number and plus of minus 2 to all of them.
First numbers: 3, 7, 11, 15, 19, 23, 27, 31, 35, and 39
Second numbers: 1, 5, 9, 13, 17, 21, 25, 29, 33, and 37
The second number has ten possibilities and each number is four away from the next just like the first numbers. At this point there are only 100 combinations left!
THE THIRD STEP is to try the 100 possibilities.
Now you know all 100 possibilities, it’s time to get to work. Unfortunately, this is the time consuming part. Yes, you have to go through each one.
You can make up your own way, but the quickest way I’ve found to do it is to go through the first numbers chronologically to ensure that you do not forget which numbers you have already tried. Clear the lock by turning the dial counterclockwise something like three times. Stop on the first number (I start with the smallest, but it does not matter). Turn the dial clockwise all the way around and go to the number two more that the one you are starting with. Move the dial counterclockwise to the last number and give a little tug; enough to open the lock if the combination was correct (if you pull to violently it will move the disks that you just positioned). If the lock did not open do not clear the dial. Simply move the dial clockwise back and passed the second number you just tried and go to the next possible second number (i.e. four more than the one you just tried). Then counterclockwise back to the last number and try again. This way the dial will be set on the first number an you can simply move back and forth between each possible second number and the last number. Much faster than going back to the first number each time and having to keep clearing the dial. Keep doing this until you have gone all around the dial and did every second number possibility (1 out of 10 chances that you would have gotten it by now). If you have not gotten it open, do the same with the next first number.
It will be something like this:
1-3-15, 1-7-15, 1-11-15...1-39-15 (clear the dial), 5-7-15, 5-11-15...
When you get good you will be able to do one combination every two seconds (or more when you get really good); this means that on average it will take you less that two minutes to pass the last step. The whole process will quickly become automatic with practice.
Now you can open anyone’s locker! Do with this power what you wish, but I claim no responsibility for what you do.
