Lyceus I did that special and all the
Chinese locks that I got that had were
donated to the lab a lot of you been
asking about this one the five digit one
this one's by a company called Tong yan
but I've seen a lot of these locks
they're all identical they just have a
different name stenciled right there so
there's probably one company that makes
them all pretty nice lock you can't shim
it there is a pin here but you can't
drive it out it's punched in that way
and you have to destroy it so it's
pretty hefty lock not too bad at all
it's got ball bearing inside of it so
you can really can't shim it the shackle
I don't know if it's hardened or not but
for locking up gym lockers and things
it's probably perfectly adequate these
come preset for all zeros so you just
line up all zeros and then comes right
open now
here's the funny part if you want to
reset this and obviously you will the
instructions are right there very
clearly written in Chinese but if you
don't read Chinese that's alright all
you do you take the end of it and you
rotate it 90 degrees and then you set
the combination you want let's say one I
don't know five seven nine five seven
so five seven nine loops and then we
take a five and then seven so five seven
nine five seven once you get what you
want you rotate that back and then
that's your new combination pretty easy
stuff
go back all zeros and she's not opening
and that's the way it's supposed to work
all right let's talk about picking it
it's not so difficult to pick it works
like any bicycle lock all you need to do
is apply tension to the shackle and when
you apply tension to the shackle it'll
put pressure on the locking ball bearing
which in turn puts pressure on these
disks causing one or more of them to
bind up and you have to put quite a
significant amount of pressure and once
you've done that you find the binding
disk then you turn it until you sense
and you feel that you have the right
number and by the way the lock will tell
you when you've got the right number
let's go ahead and put this in a safe
and I'll show you exactly how to do
and how easy it is to pick through these
five digit combination locks all right I
got this thing tied up in a vise it's
actually hanging on another padlock but
that's to simulate a door or you know
hasp or a chain on a bicycle or
something what I want to do is take my
left hand I'm going to push down on the
body you could do it from the bottom but
that's a little bit awkward on camera so
I'm just going to push down and when I
do that I'm placing tension on the
shackle which is binding up one or more
of these disks and the way we figure it
out is we just go disc a disc and you
just click them and you figure out which
one has a little bit of binding now two
is binding let's see if anybody else
three is okay for Scot binding
yep force binding and five is free so
two and four let's begin with two so
let's just go one number at a time I get
my fingernail in there and you just keep
rotating until you feel that shackle
fall into the gate and it just did I
don't know if you saw that but it
literally will jerk as it hits now
there's the funny part the lock will
confirm that you're on the right number
and the way it confirms it is you notice
that I it goes half a click in either
direction and actually holds there if
it's on any other number it won't do
that it only does it once you get inside
of the gate so that confirms that seven
in this case is the right number now
let's find a next binder that one is
free that one is free that one is really
binding so we're going to take disk
number four I'll go down so you can see
what we're doing my thumb won't get in
your way
okay now we need to watch it it'll fall
into the gate when we get to the right
number and there we go again let's
confirm it and we get a click either way
and it locks in place now for any other
number it doesn't do that so let's put
it back on five so only it does confirm
so that five is the second number now
let's find the next binder okay he's
okay that one is really binding and as
it happens I just fell into the gate
again it doesn't happen anywhere else it
only happens when it pops into the gate
they're half click in either direction
we got the right number okay let's
go to the next one let's write here now
this one is finally binding so let's
rotate him when he's really bunny I'm
gonna let up on the pressure a little
bit there we go and just click until we
fall into a gate and there we go there's
a confirmation it clicks in both ways
and nowhere else on the combination does
it do that so 1/2 click in either
direction and we're there and of course
we're on the last one
since you know all those are right you
can really let up on your tension and
just kind of roll it and you're when you
get to the right number she's just kind
of pop open for you so these are not bad
there's some delay mechanism a added by
adding that last digit so it's not like
a four digit combination which usually
open fairly quickly on bicycles but it
takes a little bit of extra time because
of that extra number to figure out these
are great little locks for things like
wall lockers and you know gym lockers
things like that but please don't use
them to lock up your shed or say a
valuable bicycle because you see how
easy they are to pick open anyway fellas
appreciate your time stay safe stay
