2 Digit Combination Lock Possibilities

Within the art of lock picking lies the infamous combination lock, a device allowed to our tension wrenches, lock picks, and standard methods of lock picking.

While there are all the same many other means to bypass a combination padlock, including the use of a shim, bolt cutters, locksmiths, or fifty-fifty a blowtorch, none are quite as elegant nor non-subversive every bit onetime school combination great.

A standard 40 digit Master Lock has 64,000 combinations which would take the average homo about 180 hours to crevice by using random combinations.

This guide volition aid you lot in reducing that absurd number to only 80 combinations and instruct you on how to fissure a Master Lock in 10 simple steps.

Whether you need to open a locker lock or want to learn a new skill, cracking combinations is a nifty talent to take!

1. Determine Your Model of Master Lock

Before we spend the time learning how to crack a combination lock, it'due south important that we offset make up one's mind if this method of cracking will work on your model of lock.

Some Master Locks require additional or dissimilar procedures to crack as they use unlike algorithms.

The model number of your Principal Lock tin be found on the back of the lock. If past chance your lock'south model number begins with 800 or 908, this method of combination cracking may not piece of work.

Still, many people accept had success cracking 800XXX model Master Locks using this method, but there is no guarantee.

2. Clear the Lock

The offset step in picking any blazon of lock is to set a standard starting point.

In the case of a Master Lock, nosotros simply clear the lock. This is achieved past rotating the dial, at minimum, three times past the nothing marking in the clockwise (right) direction. Additionally, exist sure to stop the rotation at the zero marking as well.

3. Place Tension On the Shackle

Now that the lock has been cleared and is set at zero, our showtime objective, which will seem backwards, is to detect the tertiary number in our combination.

Parts of a Combination Master lock Begin past applying a tense pulling force on the shackle of the padlock. A great method of doing this is to grasp the lock in one hand while using a finger to push upwardly on the shackle.

While maintaining this upward pressure on the shackle, begin to rotate the dial slowly in the counterclockwise (left) direction.

Note here that there may be a take chances the dial will be stuck on the zip mark while force is applied to the shackle and will not allow you to rotate information technology.

If this is the case, release the forcefulness on the shackle and rotate the dial ane or two numbers counterclockwise.

Reapply the upward pressure on the shackle and once once more attempt to rotate the punch counterclockwise.

4. Finding the First Sticking Signal

While rotating the dial of the lock in the counterclockwise management, you will shortly come to a point where information technology will jam and no longer allow you lot to freely rotate it.

The dial will be stuck in a rut betwixt two numbers. Yous should be able to plough the punch slightly in the clockwise (right) direction and back again while still property pressure on the shackle.

This is our first "sticking range." Write downwardly both stopping points in this rut.

For example, the counterclockwise (left) stopping signal could be 8, while the clockwise (right) stopping point could be 6. In this instance, our sticking range would be 6 to eight.

Next, we have to detect the "sticking point." This is washed by but taking the center number of our sticking range.

In our instance, this would be 7.

Cracking the first number in our master combination lock.

Be aware when finding your sticking range that the dial can as well stop between numbers or, that is, halfway.

An example of this would be when turning the dial in the counterclockwise direction to find your stopping point and it instead stops between 8 and 9.

Your counterclockwise stopping indicate would then be viii.5. In addition, when you rotate the dial in the clockwise position, information technology stops between six and 7 giving you a stopping point of 6.5.

The resulting sticking range would be 6.5 to viii.v and our sticking point would be 7.5.

Finding the Halfway point on our first combination lock number.

five. Finding the Second Sticking Point

Now that we have found our first sticking signal, we can move on to the second sticking indicate.

Release the upward tension on the shackle and rotate the dial counterclockwise until you lot are but past the higher number of your last sticking range.

For instance, if your previous sticking range was 6 to 8, rotate the dial to 9.

Side by side, reapply the upward tension on the shackle and merely as before, turn the punch in the counterclockwise direction until it once again jams.

Take note of this counterclockwise stopping point and, with tension notwithstanding applied, rotate the dial clockwise until it stops once more, giving you your clockwise stopping betoken.

Once again, record the sticking range and decide the middle number to find the sticking point.

6. Finding the Remaining Sticking Points

We now accept 2 of the 12 sticking points we need to scissure the 3rd number of our combination.

Echo the following steps of rotating the dial in the counterclockwise direction and finding the sticking points until y'all accept 12 numbers recorded.

Below is an instance of the sticking ranges and sticking numbers I nerveless while cracking the combination of my Master Lock.

Finding all sticking points for give us all possible combinations.

seven. Cracking the Third Number

If you take a wait at the sticking points yous have recorded, you might find that there are seven fractions and five whole numbers. Cross out all of the fractions leaving only the five whole numbers. In our example, we are left with 0, 10, 20, 27, and 30.

Now that we have all the possible combinations, we need to start crossing some out.

If you did the steps above correctly y'all will discover that all of your remaining numbers end with the aforementioned digit, except for one.

This oddball is our lucky winner as it is the third number in our combination.

For example, my numbers are 0, ten, 20, 27, and 30. All of which cease with 0, with the exception of 27. The 3rd number of my combination is therefore 27.

Finding our last number to our combination!

eight. Finding the First Number of the Combination

Now that we have cracked the third number of our combination, we tin can determine the x possibilities regarding the first number of our combination.

The first step is to take the newly constitute third number of our combination and divide it by four. In my case, 27/4.

Finding the first number in our combination

Of this new resulting number, nosotros are simply concerned with the balance, or that is the decimal point. Write this number downwardly. In my case I resulted in half dozen, making my remainder 3.

Likewise annotation that with these locks, the residuum volition always be either 0, 1, 2, or 3.

Now that we have our residual, it'south time to find our ten possibilities for the first number in our combination.

Brainstorm by calculation iv to the remainder and write it downwards.

So once again add iv to that effect and continue adding four to each resulting number until you have a total of ten numbers. In doing this, your tenth and largest number should exist a number available on the dial.

One of these x resulting numbers is the kickoff number in our combination. In my example, the balance was 3 and as I continuously add iv I result with the numbers three. 7, eleven, fifteen, 19, 23, 27, 31, 35, 39.

These are my x possibilities, 1 of which is the beginning number in my combination.

Be aware, if your lock is of the 800XXX models, this prepare of numbers could perhaps be for the second number in your combination instead of the start number.

9. Finding the Second Number of the Combination

To find the 2nd number in our combination nosotros again need to await at the residue we used in the previous pace.

If your remainder was 0 or 1, and then add two to it. If your balance was ii or three, then subject two from it. Take this new number and add together 4 to it.

Just equally nosotros did in the previous footstep, continue to add iv to the resultant until y'all once again have ten resulting numbers.

In my case, the remainder was 3, and so I would subtract two giving me a new number of one.

I then continuously add iv to my new number giving me the following ane, 5, ix, 13, 17, 21, 25, 29, 33, 37.

We can narrow these ten numbers down slightly more by removing any number inside two of our three combination numbers.

In this case, considering my 3rd number was 27 I can remove 25 and 29 leaving me with ane, five, 9, 13, 17, 21, 33, 37.

These are my viii possibilities, one of which is the second number in my combination.

In one case again, if your lock is of the 800XXX models, this set of numbers could possibly be for the commencement number in your combination instead of the second number.

ten. Cracking the Combination

We at present have all the possible get-go and second numbers for our combination and have for certain our tertiary number.

Nosotros accept taken a possible 64,000 combinations and diminished it to eighty possible combinations.

The adjacent step is to simply hash out all the possible combinations until one works.

Let'south get-go by entering our first possible combination. In my case, it would be iii - 1 - 27.

First, yous must again clear the lock past rotating the dial a minimum of three times in the clockwise management. So while continuing to rotate the dial clockwise, enter your first number.

Mine is 3.

Next rotate the dial counterclockwise by your second number and continue to rotate it until y'all state on that number once more.

Mine is 1, so I rotate past i and proceed turning until I one time again land on one.

Finally rotate the dial once more clockwise to your third number.

In my instance, information technology was 27.

It is very likely that your first combination won't piece of work. Merely continue to clear the lock and enter every possible combination until you detect those magic numbers.

My combination ended up beingness 19 - v - 27 and took me roughly 15 minutes to scissure.

Y'all now know how to crevice a Main Lock!

Happy Picking!
