Yale P150 combination

[hurri]

I bought today a Yale P150 padlock. Do you know any methods of opening? I tried everything i know, but it was worthless. It has 3 dials and you can change the combination.

Try using a peterson mini knife.

Are you familiar with sesame picks/decoders ? Are you familiar with how these work, because on some cheap ones, you can actually find out the combo with nothing more than a bright light ?

Well.. actually, I'm going to assume the answers to both the above questions are 'no' .

Soo.. here it goes.

Each dial, is connected (or part of) to a wheel. These wheels prevent a fence from going into a position where it would allow the lock to open. Each one of those wheels have a gate (usually a cut-off flat spot on the circle). When you line up all those gates, the fence pops into place and the lock opens (as it would in spin dial combination locks). With some locks, you can actually find this gate by looking (with a flashlight preferably) into the holes on the sides of the wheels, if they're big enough. If not, use a shim to try and find this gate (refered to as a sesame decoder as far as I know).

Thx for your help.I'll practice more and I'll let you know when it's done.The padlock it's a Yale P150, and i know a few things about combination locks..I'm not familiar with sesame decoders.Mainly because i live in romania, and everything i have i bought from southord.Thx again.

back.i managed to pick it. i used some shims made from soda cans. i made a vid about it.the quality isn't so good because i used my cell phone, but i hope that you will understand what i've done...pull the shackle,rotate the wheels and usually you can do it. more details about this on my website. you find the link on youtube vid.

You dont need decoder or feelers or anything with this style. Just pull real hard on the shackle and dial in numbers. Start from the top, when you dial in a number that becomes reallly hard to move. Then move on to the next number. Keep going till the lock opens. Another way is to pull real hard and start at the top tumbler. Set it to your first digit, While pulling hard on the shackle test the second row tumbler by moving it. If that row is easy to move, with no resistance, then go back to the first row and do (n+1) then go to the second row and see if there is any resistance. If there is resistance (true) Then repeat the same process for the second row, by using the third row as your test tumbler. When you finally have decoded the first two tumblers, just try every number on the last tumbler till the lock opens. It works every time. This yale doesnt have any false gates, so it should be very simple, and fun! You can impress anyone with this trick
If this was a computer program, it would look somthing like this.

(lambda 0 0)

((lambda currentgate position)
while(currentgate != nil) (
( if (currentgate+1) = (hard to spin)
(print "current gate") AND (lambda (currentgate +1) (0))
else ( lambda currentgate (position + 1))
))

That program will give you the first set of numbers in your combination, then to figure out the last number you just have to brute force it. So just plug this program in your lock, it should work fine.

blah blah blah

#include<iostream.h>
void main()
{int n;
cin>>n;
{while(n==thank.you.very.much) ok=1;}
if (ok==1) cout<<"Thx again"
else cout<<"Thx.";
}

thats pretty much what that vid explained
u just done it a bit better and without a video
