“I tried to do this and Im obviously not doing something right. I ended up with too many whole numbers.”
You’ll have to examine the whole numbers more closely. I used to use (and still do use) the 3 cross method for finding the last number. You pull up on the shackle as usual, but instead of advancing to the next stop, you give the dial a quarter-turn and examine the stop there instead and so on around the dial. Only then do you go to the next cross by advancing 1 stop past the very first stop you started on. An example!:
I have a lock here, the first cross is (note, I’m not averaging, you’ll see why):
2-3, 12-13, 22-23, 32-33
next is:
5-6.5, 15.5-17, 25-26.5, 35-36.5
third and last is:
38+-0, 8.5-10, 18+-20, 28.5-30
The first cross, they’re all identical, and they don’t average to a whole number anyway. All decoys!
The third cross, there’s a little slop, but the slop is paired up on opposite sides of the dial, and at least one set of ends (the upper/right end) is a whole number (0,10,20,30). Decoys.
The second cross, there’s one stop that’s just half a number off from an otherwise normal-looking decoy cross. That aberration (15.5-17) contains your third number (16).
You’ll note that the real stop is a mere half number off from all the others in its cross. With averaging, you’ll miss it. Doing all the stops in order, you’ll probably miss it. Only by hitting all 4 points of the cross in rapid succession will the minute difference stand out.
With the third number, and narrowing down the first and second numbers as usual, just tumbler bump out 10 sets of 10 combinations (never bothered to remember which 20 to eliminate) and the lock should be open in a few minutes.

I tried to do this and Im obviously not doing something right. I ended up with too many whole numbers. Are you still taking lock numbers? If so, mine is 906855. I think I came up with 24 as my last number but none of the comebo possibilities work. Please help. Thanks.

Damn, am I the only one who actually watched the video and made it work. You people just need to watch the video and do it. It works. A bit time consuming but it is better than photo copying the back of your lock/serial number, getting a notary public to certify it is your lock, mailing Master Lock, and waiting six weeks for a reply. Just watch the video,use your brain and do it….or cut the lock and buy a new one. If you can’t figure it out you probably don’t even realize that the president has little to do with the economy either-and you likely voted Communist-PS.Thanks Barney Frank and Fannie/Freddie idiots (should all be in jail) for jacking up the economy and destroying my business (R.E.Appraisal). Move to Russia!

Worked for me. I did a little guessing as the 12 initial numbers were difficult to determine whether they were whole numbers of ?.5 #s. But after seeing a trend in the 5 remaining whole numbers (23, 33, 3 etc.) I knew that the “10″ stood out and went with it. My remainder was 2 as 10/4=2 with a remainder of 2. (2,6,10,14 etc.) for the 1st poss. # combo. As you are supposed to add 0 for a remainder of 2 for the 2nd poss. # combo. was (0,4,8,12,16,20,24 etc.). I started guessing at random because I was getting frustrated with how much time this was taking…I tried three random combos with “10″ being the last # and got it on the third try. 14-24-10. Probably beginners luck but there is hope for you fellow frustrated crackers. It does work.
