I can shim my old slaymaker combination padlock...

[stever2002]

So I can look down into the guts - is there any way to determine the combination? The Master Lock Trick doesn't work.

Which master lock trick are you referring to and any chance of a picture of the lock?

[Shrub]

If you can get it open maybe pushing the dog latch in will show up the drop in points,

A pic of the lock and a better description of what you can and cant do and what you want to do would help,

How i understand it is that you can shim the lock but now want to try and determine the combo? but the master one doesnt work,

Appologies for the large pictures, but I wanted to show that there are NO markings on the back that give any hint of serial number.

I guess I'm asking if there is anyway to look or probe inside the lock to determine what the combination should be. Like I mentioned before, the Master Lock Combo trick doesn't work on this - probably because its a Slaymaker. Check out these pics:

Ive had to turn those pics to links,

If you look down the shackle hole can you see the wheels and can you see the edge of them all when you turn the dial?

Ah one of these things. I had one that looked exactly the same, cant remember the name of it. You have to line the 3 wheels up. As you look at the lock The left hand side of the cuts should be roughly behind the 0 position. Its the only combo lock ive had in bits. it could be manipulated i assume but not in the mathematical way like on the masters i don't believe.

You cant really do it effectively with the casing of the lock intact. and u cant open the lock without destroying it. Then again they things are so badly made they open if u pull hard enough.

I had the oppurtunity to shim a bunch of locks off high school lockers so they could be replaced with "key accessible" combination locks. Some were Master, some were Slaymaker, and some were an unknown Chinese type. The method that I use in my shop has worked with all types. Even with the Master locks, it reduces the number of combinations from 64 to about 10- 15.

First, clear the lock by turning the dial three times to the left. Then take a jewelers screwdriver and wedge the striker/ latch back so that you have a better view inside. Then turn the dial right three times until the gate on the first disc (closer to the rear) comes into view. Record the number on the dial. Then turn the dial twice to the left until the gate from the middle dial comes into view and lines up with the first dial (this can be done fairly easy by lining up the corner of the gate.) Record the number on the disc. Finally, turn the dial once to the right until the gate on the third disc (closest to the dial) comes into view. Line it up with the other two gates and record the number.

These three numbers are not the combination but rather the span needed to align the gates. Subtract ten from the numbers and pull the shackle. If it does not move, SUBTRACT one from the numbers and try again. Continue this until the shackle opens. If the shackle does not open after ten tries, return to your original number, subtract ten from each number, then ADD one as you try the shackle.

Example: You line up the gates and get the numbers 19-39-19. Subtract ten and you now have 9-29-9. Try this number. If it does not work, try 8-28-8, 7-27-7, 6-26-6, etc, until you have tried ten combinations. If one of those did not open the shackle, go back to 9-29-9 and work your way up: 10-30-10, 11-31-11, etc.

We have always been able to determine the combination on dial locks using this method. I hope I explained it in enough detail.
