Combination lock with dials/wheels that number 0 - 9

[Gary9696]

Need information for the combination locks that have 4 dials or wheels on the bottom and have numbers on each one from 0 - 9. I can pick the cheap luggage type locks with 3 or 4 wheels such as those that have the wheels on the side, but can't quite get the larger ones that have the wheels on the bottom of the lock.

I haven't found a way to get those yet, either. They're a pain.

I've never tried these. Does the "pull the shackle, feel for the loose spots" method not work? Perhaps the sesame decoder option? If these locks are impervious to both those techniques, I'd really like to know what it is.

If all else fails, you can do it with brute force. It takes about 60 minutes to run through 10000 possible combinations. Chances are it won't be the last number you try, so you could do it, on average, in about 30 minutes. If you start at 1900 and work up, you stand a reasonable chance of hitting it early, since many people would use a year for a 4 digit number. If you do make it all the way to 9999, just start back at 0000 and work up to 1900. You will find it.

I still think there's an easier way though.

There is a bypass method for these that is scary, i think peterson sells the tool or its a multipick one.

Ive just got 2 of these this morning to make my own from but i dont think its for open discussion here, db let me know, if it is ill spill the beans.

Derek was already ahead of you I'm afraid.

Shrub, I'd say spill away. This is by no means a high security lock. I don't see discussion of this topic as being any different from padlock shims.

I'm most interested to know why the "pull shackle" and sesame decoder methods would not work.

The pull shakle method doesnt work as you press the shackle in to release it once the combo is imputted correctly.

The seasame decoder works on some models but not all.

I will see if i can find the multipick pictures to link to otherwise youll have to wait for me to make one of these into a cutaway.

I hear what you say illusion but im not lining there.

[Shrub]

Wel i think the pics are restricted on the sites ive looked through, i can see them but if i linked you to the sites here you would have to join and you will only be allowed if a lockie.

Its the perterson mini knife.

You insert it inbetween the dials and basically lift the locking dog (?) out of the way, do this whilst pressing in the shackle i think and you will find the lock opens easily, i will have a quick go at knocking a tool up with a feeler gauge and then make a quick vid for you.

[Gary9696]

I think the Sasame method is adding 7 to each digit isn't it.

[Shrub]

It depends on where the flat if a flat at all is placed.

They shim easily but this is the quickest......




It took 1 minute to grind the junior hacksaw blade, it needs thinning a little as well.
Insert and lift whilst pressing the shackle in.

Open.

[Shrub]

I make it look more difficult than it is its just that i was bent a funny way around the camera, in real life its simply insert and lever up a bit.

[Gary9696]

Thanks, I'm going to borrow a lock like that. It's a Master with the 4 wheels at the bottom and study it more.

[digital_blue]

Nice vid Shrub. That's pretty cool.

Ouch! Definitely a candidate for the "it's whacha know" award!

I was all prepared to give a complex lesson in calculating brute force opening times based upon a finger numbing rate of dial spinning and shackle tugging...

I installed the Flash PLayer and still can't see the video.
