I looked but could not find any methods that they were talking about. I would like to see what they used.

Is there a 120 Chart for Combination Locks? Hmmm .....

 Thus if one holds a top-secret security clearance, one is allowed to handle ... Advances in methods for defeating mechanical combination locks have led the ...en.wikipedia.org/wiki/Classified_information_in_the_United_States - 58k - Cached - Similar pages

The only real failure .....is the failure to try.

Luck is a very rare thing....... Odds not so much.

Odds never change .....but probability does.

• If what you want are all possible three digit numbers then you have 10 choices for the first digit, you have 10 choices for the 2nd digit,and you have 10 choices for the 3rd digit giving you
•  10x10x10 = 1000 in all.
• If what you want are all possible three digit numbers with no repetition of the digits then you have 10 choices for the first digit, you have 9 choices for the 2nd digit, and you have 8 choices for the 3rd digit giving you
• 10x9x8 = 720 in all.
• If what you actually want is  - combinations - that's something quite different. It is the number of ways to choose 3 of the 10 digits in which order is not important. There are 6 = 3x2x1 ways to order 3 digits in a row.  the number of combinations of 3 of the 10 digits is 720/6 = 120 combinations.

• Its funny how every combination lock requires you to put the numbers into the lock in a particular order.  Perhaps they should have called it a permutation lock instead! lol

You are right Thoth ! That's exactly correct.... it would be a permutation not combination. LOL

Hey look at this ..... I think they are saying you can get the first combination  permutation  number using our " MIRROR numbers" LOL  Check it out.... add 5 digits to the number. LOL

HOW TO OPEN A MASTER COMBINATION LOCK

How do you get those Master combination locks open when you've
lost the combination? I found this file on a BBS and re-edited it to
make sense
. There was no reference to an author, so he will remain
forever unknown.

The Master Lock Company has made this kind of lock with a built
in protection device
. When you pull the shank of the lock (the part
that springs open when you have given the lock the correct
combination), the combination dial will not turn. That failure to
rotate provides the key to being able to open a Master combination
lock once you have forgotten the combination (something we are all
prone to do!). There are three (3) numbers to a Master combination
lock. You might want to get out a lock to understand easier.

To determine the first number:

Grasp the shank and gently pull on it. Do not pull it too hard
or the dial will not turn at all! While pulling on the shank, rotate
the dial to the LEFT until it will not rotate any further. Read the
number under the index. Add 5 to this number and you have determined
the first of the three numbers.

To determine the second number:

Relax the pressure on the shank and turn the dial completely
around three to four times to the left. Rotate the dial to the right
to the first number you determined. Then rotate the dial further to
the right, bypassing the number once
. When you have bypassed your
first number, again gently begin pulling the shank and continue
rotating the dial. It will eventually fall into a "groove" and the
dial will cease to rotate
. While in the groove, pull on shank and
turn the dial. If the dial is lose and feels sloppy, go to the next
groove
. If the know will not rotate at all then you have determined
the second number.

To determine the third number:

After getting the second number, relax the pressure on the shank
and re-spin the dial. Then enter the first two numbers. After the
second number, go to the right and at all the numbers give the handle
a pull. The lock will eventually open if you did it right. If you
can't do it the first time, be patient. Lock picking is not learned
overnight and it takes time
.

The only real failure .....is the failure to try.

Have a couple of locks around the house I don't know the combinations to, so...., easy getting the first number. Haven't got the second one yet

But this being lottery discussions, I was thinking....what if there were locks that only had 0-9 on the dial, not 0-30. Would be a heck of a basis to work a system out on, maybe that would be a good approach, to think of the pick 3 that way.

Just a thought.
