How to unlock digital lock
How to Crack the Code & Open a Combination Padlock
0:00 / 0:00
if you've forgotten the number to your
combination lock it can be really
annoying today I'm going to show you how
to open one of these padlocks without
knowing the number I'm starting with
this 3 dial combination lock it's about
6 centimetres tall and it feels
relatively sturdy we need to start by
pulling a little on the shackle to apply
some tension to the lock I do this just
by pulling back with my finger like this
next we need to rock each one of the
dials back and forward to see which
one's got the most resistance on in this
case is the top one so we start here we
need to rotate the dial slowly between
each digit until we feel a small break
in resistance on the wheel here number
five feels a lot freer than the other
digits so we move on to the next style
and is the same procedure keep some
tension on the shackle and rotate to the
dial until we feel a change this time
number eight feels a lot looser so we
move on to the last oil if we've got the
other two numbers correct it should just
be a case of going through each of the
digits one by one until it pops open and
there we go the combination was 582 here
I've got a slightly bigger and sturdier
padlock with four dials but to open it
it's exactly the same principle apply
some tension to the faculty Isle has the
most resistance and start with that one
until you feel a change in the pressure
for this one number eight feels freer
and if I rock the dial back and forth I
can actually see the shackle moving
slightly in and out if I put a piece of
tape around the shuttle it might make it
easier for you to see - it's actually
moving quite a lot and this helps to
confirm that digit eight is correct
now we need to find the next style with
the most resistance and repeat the steps
here number nine is a lot freer these
bottom two dials feel about the same
with resistance so I'll start with this
one
this time zero feels looser and the
shackle moves slightly too so it's on to
the bottom one and there we go
combination eight nine zero one two
change the combination on these locks we
bring the shackle to the side and put it
in this position then rotate the dials
to the new number now when we close it
and change the dials it should be locked
and it opens on the new number this time
I'm gonna change the number combination
with it hidden in the palm of my hand so
I've got no idea what the number is I
lock the shackle and scramble up the
dials so I genuinely have no idea what
has been set to so I go through the
process again to crack it apply tension
and start with this style this time the
break-in resistance is on number one
dial 2 is a bit difficult but it feels
like it's number 5 this time the bottom
dial feels like it's got a bit more
resistance so I work on this one and I
think it's number 3 then I move to the
last one keep rotating it and number 2
pops it open there we go I had no idea
what the number was but I was able to
open it it goes to show that as
convenient as these locks are they do
have security issues and vulnerabilities
so do be careful of course if you have
one of these locks on a shed or
something you apply the tension to the
shackle by pulling down on the lock then
go through the procedure before I go I
wanted to show you this reproduction
Chinese brass antique combination lock
it's got five barrels with Chinese
symbols on which rotates like this and
although I bought this new I didn't have
a combination for it
so I went through a similar process to
open it I applied some pressure to the
lock and went through each ring one at a
time I did find this very fiddly because
it's quite small but I was definitely
able to feel when I got certain dials
into the correct position and the more I
got correct the slacker the lock began
to feel until I finally got the last one
in position and opened the lock
pretty cool huh it really is a great
little lock and you can see how it works
when we rotate one of the dials the gap
at the top moves around which stops the
other half from sliding out they all
need to line up and of course there's
five altogether and just the slightest
bit of misalignment will stop the lock
opening all going back together I really
like this lock though and if you want to
buy one there's a link in the
