okay today I'm going to teach you how to
crack the combination on one of these
combination master locks and there's a
couple of different ways of getting in
by picking the lock and it only takes a
few seconds but you don't get the
combination of the lock this is how you
can solve the combination and if you
just tried trial and error there's over
64,000 different combinations so what
we're going to do today is we're going
to narrow it down to just a hundred that
you can crack in just a few minutes now
the first step to this as is you put it
to zero and then by holding tension here
you move it to the first number where it
looks and if you notice it's a it
catches between three and four and so
the first number I'm going to do is
three point five because it's halfway
through and after we have that number go
to the next one and as you can see it's
halfway in between six and seven and so
the next number is going to be six point
five and you do this all the way around
until you've gotten to the end and this
third one is it locks up in between nine
and a half and ten and a half and so our
number is going to be ten and it's
important to keep track of these numbers
I did this earlier with just bought this
brand new lock and I never looked at the
combination and so I already went
through and did this after ten i got
fourteen point five sixteen point five
twenty twenty three point five
twenty seven thirty thirty three point
five thirty six point five and zero and
if you if you notice there are going to
be five whole numbers and in this case
my lock gave me ten twenty twenty seven
thirty and zero and now notice four out
of five of them end in a zero and you're
going to find this on whatever lock you
use and so the odd number out that I
have is twenty seven and that is going
to be my third number in the combination
so we've already found one of our
numbers and that's the last digit so now
what you do is to take that number
twenty-seven and divide it by four and
you get six remainder three and it's
important to know the remainder because
that number is what we'll be using here
so you take that number which is three
and you start with three on the lock and
write down all the numbers so put three
down and then add 4 to it and go all the
way around the lock and so you come up
with 3 7 11 15 19 23 27 31 35 and 39 now
these are going to be possibilities of
your first number and how we get the
second number is if we use our remainder
again which minus three there's a
certain code if your remainder if you
don't have a remainder then use the
number two if you have a remainder of
one use three
to use zero and three use one so if it's
zero or one you add two to the digit and
if it's two or three you - two from the
digit and so since - three I'm going to
use one and then just do the same thing
add four to your number and then go all
the way down the list so I'm going to
end up with 1 5 9 13 17 21 25 29 33 and
37 and these are going to be a list of
your second number and the third number
we already know is going to be 27 and so
from here it's just trial and error
start with 3 127 see if it works 3 5 27
3 13 27 and then go down the list and
then with 7 11 15 and so on and
eventually you will get the combination
in my case I ended up with 15 37 and 27
those were the numbers that opened my
lock here 15
37
in 27 and there you go you just crack
the combination to the lock
