hello and welcome in this video I want
to show you this four wheel combination
padlock from master it was sent to me by
no trick pony lock-picking and he
decoded it in one of his videos he
mentioned that it gives strange feedback
and this made me very curious I asked
whether we could trade it for something
and he was so kind to send it to me
so cool Rick thank you very much for
this luck was a was actually a challenge
for me to get it mastered the master
lock so before I show you the details of
my method I want to show you these these
locks that I've already decoded they
fall into two groups the left-hand side
type are locks with only true gates so
for example the red Able's I've decoded
in video 101 and the basic method is to
pull the shackle and pull the shackle
turn the wheels search for the binding
wheel the one that turns the hardest and
yeah try every every number and when you
get the right number it stucks or the
shackle comes out a little bit and so
you continue until it's open here I have
one with also for skates the method is
different you pull the shackle when all
are in a true or a false gate and you
test every wheel and the one that is
bound the most so which is currently
connected to the bolts of the shackle
that one that binds the most and has to
be turned to the next gate or true-false
gate and so you continue with every
wheel until it's over
I have shown this in my video 115 so get
away with that
so if this lock is is different I think
it has no false gates but yeah it
behaves very strange so let me prepare
my environment and then I will show you
how I decoded so my setup is ready
I have something to cover the lock when
I shall for the wheels to change the
combination but before I want to show
you that it tests actually no false
gates so currently all 0 is the right
combination and I close it and turn it
to 9 better now pull on the shackle I
can feel resistance for every position
the same amount of resistance until I
turn it all around and come back to 9 so
I would say it has no false gates but
nonetheless it picks very strange or
decodes very strange so I push it down
at 90 degree cover the lock and shuffle
the wheels now I make sure that every
wheel is at exactly one position release
the shackle turn it and close the lock
and shuttle the wheels again it's locked
up and I will just make sure that 0 0 0
is not the right combination anymore you
can see it's locked up alright what you
have to do in order to get this look
openness pull the shackle and turn the
rules on in a way that you search for a
wheel that gives feedback so this one
does not give feedback so it turns all
the way around without any change of
resistance here a few resistance and I
try to feel where the wheel stops
because the resistance and I turn it
back and these two end points I try to
memorize and choose something in the
middle so
just like and the area where it turns
free I choose the center and that's what
I do with every wheel and it's a little
bit of guesswork not an exact sign so to
speak but when you make this more often
so when you do some more passes or pass
then you're getting closer the number
one is not really giving nice feedback
so I'll just leave it somewhere go back
to last one turn and here it stops and
maybe here not really sure so stop and
stop show something in the middle
sometimes you need to release the
tension in the shack so that you can
start moving a wheel and for number one
I'm never sure where where it wants to
be so number two stops here and stops
tear shoot something in the middle stops
here stops there
and it's open so as I said it's not an
exact science you have to guess and have
to make multiple runs through rebuilds
but sooner or later it will open for you
and I tried many other methods so just
pulling on the shackle turning one wheel
and feeling if it makes a click or gives
feedback on your shackle so that it
comes out a little bit or that will
suddenly stucks
but doesn't work on this lock I also
tried pulling the shackle and trying to
see which wheel moves a little bit and
then turn it to yeah to make it free so
that the shackle or the little bolt on
the shackle doesn't interact with the
wheel anymore but although this does not
work so I really have to have tried a
lot of things but actually only this try
and error and and the feeling it yeah
these finding of the free area with the
to stop points actually turned out to be
a working method yeah if anyone knows
how this lock looks inside but really
appreciate to see some pictures I could
cut this lock in a destructive manner
but I don't want to destroy it but I'm
really curious to see what you
understand how it internally works all
right so thank you very much for this
great decoding experience and everybody
else thanks for watching and happy
picking and decoding bye bye
