[198] Close Up On How To Decode A Dial Combination Lock In 8 Attempts Or Less

hey guys how's it going this is the Alfa

lock-picker here and the video I have

for you today is going over how we can

decode one of these style combination

locks and eight attempts or less and in

just a few minutes more information is

coming up on this topic in just a second

please stay tuned alright so let's get

started the first thing you're going to

need to do is be able to open up one of

these locks very consistently and if you

need a refresher on how to open up one

of these logs when you have the correct

combination what I'm going to do is put

a link up on the top here and that will

give you a strong overview on how these

locks work and then you can pick up the

video right here where you left off so

when we first start to mechanically

manipulate these locks we can get three

sets of numbers the first number we're

going to find is going to be called the

sticky number and then the second and

third number are going to be called the

guessed numbers these numbers are going

to help us determine the final

combination of the lock and I'm going to

get into it right now on how we're going

to be able to get started with decoding

this lock all right so we're ready for

step one which is going to be finding

the sticky number in order to get the

sticky number we are going to

mechanically manipulate the dial and we

will be able to write that down in order

to do this we are going to turn the lock

clockwise several times just to

completely reset the lock now we're

gonna put some attention on the shackle

and we're going to pull up until it

starts to seize the lock this is going

to be too much tension and we're going

to need to let off just a hair so we can

start turning the lock in order to find

the sticky number what we're going to do

is we're going to turn the dial

clockwise with our eyes closed and we're

going to keep turning until the dial

stops on a number so it just stopped

on nine it just stopped on three but

we're just going to keep going until we

can consistently get the same number it

stopped on three again it stopped on

three again and it stopped on three

again and now that I'm on three I'm just

going to turn past it you almost feel

like you got to go over a little hump

and that is another great indication

that you are on the correct number so

since I was able

to get three three times in a row and it

felt like it had some resistance when I

turned past it I'm going to write down

three as my sticky number you need to

remember this number it is going to be

very important down the road so let's

get started with the next steps all

right so we're ready for step two which

is finding the two guessed numbers these

two numbers are going to lie between 0

and 11 and we're going to be able to get

these numbers by mechanically

manipulating the dial counterclockwise

in order to do this what we're going to

need to do is apply heavy tension to the

shackle and we're going to start to turn

it the number that we're going to find

is going to sit in the middle of two

half numbers so as we immediately start

off here you can see that we're between

39 point five and zero point five so

that is between two half numbers so

we're gonna write down zero as our first

guest number we're gonna let off the

shackle and then we're going to put back

on the tension and then we're going to

find the next one so now we have jumped

into 2.5 and 3.5 you can see that we're

between two half numbers so we're going

to write down three is our second guest

number but just to illustrate what would

be a wrong number we're going to go down

the rest of the way you can see that

this one is between six and seven those

are exactly on whole numbers so those

will not be the correct numbers and then

you can see the next one is between nine

and ten so what we're going to need to

do is just write down our two guest

numbers and we're going to move on to

the next step

all right so we're moving on to step

three which I call the mouth

step three can be broken down into three

parts part a is going to be called

finding the first digit to our

combination Part B is going to be

finding the third digit to our

combination and then Part C is going to

be finding the eight possibilities to

the second digit of our combination and

I'm going to get more into this right

now I'd like to first start off by

saying for the scope of this video we

are not going to be focusing on the Y

we're going to be focusing on what we

need to do to get the correct

combination to our lock

so we have now moved on to step three

and we're going to be doing Part A which

is finding the first digit to our

combination what we need to do is

remember back to what the sticky number

was that you found earlier in our

example on this lock our sticky number

was the number three so what we're going

to need to do is take our number three

we're going to need to add the number

five to it and that is going to give us

the first digit to our combination in

this example our first digit is going to

be the number eight and we're going to

write that down and we're also going to

need to use that in the further steps

all right so we're going to be moving on

to Part B finding the third digit to our

combination and this is where it can get

a little bit tricky but I'll try to have

you follow along so we're going to need

to go back to Part A for one second and

just recall the first digit to our

combination that we found which was the

number eight on your lock it may be

different but on this particular lock it

is going to be eight what you're going

to want to do is divide 8 by four for

every single lock it is always going to

be divided by four that will be a

constant the most important thing you're

going to note when you do out this

division is what the remainder is so

eight divided by four is going to be two

with the remainder of zero depending on

the number that you had for your first

combination you may have a remainder of

zero remainder of one two or three write

down this remainder and is going to be

very important when you are following

along so now we're going to need to go

back to what our guest numbers were on

this particular example we saw that the

two guest numbers were zero and three

and we're going to now make a little

chart so we're going to write down zero

and three and then going across we're

going to add 10 to them three times so

I'm going to have 0 10 20 and 30 and

then we're going to have 3 13 23 and 33

so these are going to be possible

combinations to your lock but in order

to refine this further we're going to do

a couple steps we're going to remember

what the remainder was when we did the

first number of our combination divided

by 4 on this particular example it

turned out to be 0

but for you it may be zero one two or

three so please remember to use the

remainder that you found in order to

find the two possibilities what we're

going to do is divide each one of these

numbers by the constant divisor of four

and we're going to note the remainder

when you find a number with the same

remainder it is going to be a

possibility so 0 divided by four equals

zero with a remainder of zero which you

can see here 10 divided by four is not

going to have a remainder of zero it's

not an even division 20 divided by four

is going to be 5 with a remainder of

zero and that is going to be a

possibility so we're going to go through

each one of these numbers we're going to

make sure that the remainder that you

find when you divide it by 4 is equal to

the remainder that you found on your

lock and when you find those two numbers

they're going to be two possibilities to

the third combination of your clock and

now I'm going to show you how we can

refine that one step further now we've

been able to determine that 0 and 20 are

two possibilities for the third

combination of our lock if we'd like to

further refine that what we can do is

mechanically manipulate the lock and

eliminate one choice this is a very

great thing to do because that will

reduce your total possibilities from 16

down to 8 once we get all the numbers so

I'm just going to turn the dial a few

times and we're going to stop on each

number so we're going to go over to 20

we're gonna put heavy tension on the

shackle and then we're going to try

turning the dial that feels very tight

and then we're going to go over to zero

when we get over to zero we're gonna put

heavy tension on you're going to notice

that zero just feels a lot looser than

20 did the number that feels looser is

going to be the last digit to your

combination so at this time we can

safely eliminate 20 as a possibility and

that will bring our total combinations

down to eight once we find the second

combination all right so we're moving on

to Part C finding the second digit to

our combination lock so this is going to

be all about remainders and it may get a

little bit confusing and I'm going to do

my best so you can follow along so we're

going to need to recall back to part

be where we found the remainder to our

lock on the example that we have in

front of us the remainder was zero but

your remainder may be zero one two or

three so what we're going to do is we're

going to take that remainder and

substitute it and so we're going to make

a chart like this in order to get these

numbers in the first row we're going to

take our remainder which in this example

is zero and we're going to add 2 to that

so 0 plus 2 is going to be 2 so I'm

going to put that 2 down right here when

we move on to the second row we're going

to take our remainder we're going to add

2 to it and then we're going to add 4 to

it so 0 plus 2 plus 4 is equal to 6

another way to look at this is you can

take the number from the first row and

you can simply just add 4 to it so how

we make this chart is we're going to

take these two numbers here and we're

going to add 8 to them and we're going

to do that 4 times going across so we're

going to get to 10 18 26 34 6 14 20 to

30 38 if we passed the number 39 and we

get to the number 40 we need to remember

that 40 is the number 0 and for example

41 would be the number 1 so what you're

seeing in front of us here is 10

possibilities if you remember correctly

I said that we're going to be able to

get this down to eight possibilities so

there's one thing that we're going to

need to understand is that when we look

at our third digit that we are able to

eliminate down to zero the second and

third digit cannot be two away they need

to be greater than two digits away so

what we're going to need to do is just

look through all the numbers and see

what we can eliminate so you can see

that 2 is within 2 from 0 so we're going

to be able to eliminate that choice and

then we're going to look over to 38 38

is also 2 away from 0 so we're going to

be able to eliminate that choice and

this has now left us with just eight

possibilities for the second number so

at this point we have now found the

first digit we have found eight

possibilities for the second digit and

we have found the third digit and now

we're going to move

to part four which is going to be

testing it out alright so we are moving

on to step four which is often the most

fun and the most stressful step which is

testing out the numbers that we are able

to find so we have the first digit is 8

and then we have the second digit is 8

possibilities and the third digit is 0 I

have listed here an alternate

possibility just in case we weren't

exactly sure on the third digit or we

did not test it the only difference is

going to be the third digit may also be

20 and then I'm going to have crossed

out 18 and 22 because those numbers are

2 away so let's get a close-up of

unlocking this log and testing out the

numbers all right so let's try out the

combinations based off of the list that

we were able to put together so the

first combination is going to be 8 and

then we are going to try 10 so we're

going to pass 10 once and we're going to

go over to it and then we're going to do

0 for the third number and we didn't get

it and we're just going to keep going

through our list until we get the lock

open so I'm just going to reset it now

I'm going to go to the next one which is

going to be 8 we're going to pass 18

once and then we're going to go over to

18 here and turn right over to 0 and we

were able to get the lock open so the

combination to this lock is going to be

8 18 0 this is something that is really

fun to learn and I really recommend you

guys try it out what I'm gonna do is put

a link in the description below of a

little Google document I put together

that might be able to help you be able

to understand this in more detail and

also I'll put a few links to some of

these locks in the description below if

you'd like to check them out but either

way guys this is all that I have for you

today this is how you can decode a dial

combination lock in just a few minutes
