hello and welcome to this video as
almost every day I ride my bicycle to
the place where I work and today I found
this pasture bicycle lock on the street
um of course it didn't come with it with
a key and yeah I was really excited to
take it home and to play with it to see
how long it takes to get it open
um yeah I was excited but just until I
started playing with it because yeah to
be honest it's I guess it's the worst
luck that I've ever picked and I will
show you what I mean so I apply tension
and you can very easily sing up and pick
it all the way in the pin suite and I
think it's the sweep in block pin three
and pin one in it's open so I can also
rock it I can sip it and it's open and
of course we can of break it so it's
actually open immediately so regarding a
lock security I will probably not
recommend this this lock yeah why do I
show you this this poor little bicycle
lock that's because I want to further
play with it I'm gonna open it up and
look what I can what I can do with this
lock maybe I can modify it so let's see
hold on so it was very easy to get the
two pieces apart adjusted to squeeze the
the lower part of the housing a little
bit and it came off and
when I pulled out the top cover here a
lot of small pieces jumped around which
came out of this hole here it's empty
now you only see a little bit of a
breast piece which is connected to the
to the plug and which moves or turns
when you turn the plug now finally
managed to find them to find the pieces
again on the floor and here they are
it's the locking bolt itself which goes
in like so and then we have the spring
and this top plate which secures to the
spring or should secure the spring you
can see that it's not really a it's not
a tight fit and this was actually held
in place only by the top cover so when
you managed to get off this this top
cover or cut a hole in here cut it or
whatever and which is think pretty
pretty easy the jug the lock just opens
by itself so not very secure also in
disrespective so now we can when I push
it in all the way we can see the locking
bolt inside the hole here see the boat
yeah what else we can now see the this
brass piece here which secures the the
drivers and intended the springs and we
have a retaining pin which prevents the
plug from being pulled out and turned
too far and I wanna try to get off this
brass piece here this top plate and
maybe I can pull out the retaining pin
then we'll take
further apart okay I clamp the lock in
my wise and hopefully this top plate
comes out without any problems hold my
thumb and it could expect some Springs
yeah yeah we have three Springs it's a
three pin lock as I already suspected
here is the top plate and now let's see
if I can oh no first I will pull out the
springs little steel springs
try to pull out the retaining pin so
here are all the pieces in this lock I
finally managed to get out all of them
the retaining pin was the most difficult
part first I wanted to pull it out just
like so but this didn't work and I had
to enlarge the hole and then yeah
retaining pin came out by itself so what
do we have in this lock we have the
three pin stacks with the springs we
have the retaining pin and the plug
that's the groove for the retaining pin
which restricts the turning angle of the
of the block and prevents the plug from
being pulled out and we have to this
cutout here which goes in the in the
edge here of the locking bolt so the
locking bolt is spring-loaded with the
spring and it's being pushed downwards
and it's holding the board from the
cable in place like so and it's
connected to the plug and this groove
when this cut out and now in the plug
turns locking bolt is moved upwards a
little bit and is giving free the bolt
from the cable so now let's have a look
at the pins you can see interestingly
the key pins are a little bit smaller
from the diameter than the drivers and
they are tiny and they are rounded on
both ends so for a manufacturing process
this might be easier and so don't have
to pay attention which way around they
put it in and also the drivers are
rounded on those ends
so this of course makes picking a lot
easier and the tolerances in this locker
are really bad just look at that I can
see the difference in the spacing so
from one to two there is a smaller gap
than from two to three and it's made
really really poor don't know how it
looks like when you insert key pins in
the holes in the chambers you can see
how much how much play they have it's
it's a horrible
so I actually wanted to yeah I wanted to
try if I could improve the picking fun a
little bit by modifying chambers and
pins and so on but I don't think it's
it's worth the effort because when you
have a lock with these bad tolerances I
think you can do what you want and yeah
you will not change the picking behavior
behavior in a remarkable manner well so
then that's it
it was picking here so to speak of this
of this lock and a little bit of an
autopsy I hope you enjoyed it
nonetheless playing with the master
cable bicycle lock thanks for watching
and happy picking bye bye
