Master Thumbwheel (175) Padlock

by **sipher** » 3 Mar 2005 22:15

I'm a super noob to picking and just bought this master 4-wheel combo lock. Has anyone figured out a way to get the combination without using a feeler?

Yes cypher. Check out this thread. If you scroll down to my post I detail the method.

Hope this helps!

db, the 175 doesn't apply direct pressure from the shackle to the wheels; once you put in the combination, you have to push it in, then it pops open. I don't think your method works on these.

My mistake. Carry on then.

Wish it did work. I like these locks and I have one here whose combination I haven't known in years. It's got a hole for a change key, so I could probably change the combo if I could get it open... I remember that my dad managed to crack it once by random wheel spinning, but I haven't got the patience for that.

Do you know, vec, if these can be shimmed easily?

I don't have any shims and am almost certain that a makeshift one would be a colossal waste of time, but anyway, I doubt it seriously. If nothing else, the shackle is very tightly machined.

Interesting... this might be a good answer for my friend with the shoplifting problem. All-in-all combo locks would be more convenient for him because his staff wouldn't have to go looking for a key.

Ok, does anyone out there know of a simple way to bypass these things? If you can not "feel" it out, then I would not be all that worried about somebody trying to brute force it. If the staff doesn't notice some thief trying all the combinations, I figure he earned it!

Anyway, if somebody has can tell me a reason why these locks are not overly secure (shy of destructive bypass) let me know. Otherwise, I might just have to go out and get one of these myself.

The master four wheel looks a lot like the sesamee, but if memory serves, one of them has a four fence comb that fits the flats on the side of the wheels , while the other has a two fence comb and the flats of the the first two wheels face each other and the flats of the second two wheel also face each other, I have heard that petersen has something called the mighty knife that can reach in and open it anyway very quickly, if anyone can confirm that from personal experience pipe up here.

Yes, that's correct. The method is outlined here with an auto "feeler" - http://www.geocities.com/masterunlocked ... heel2.html

However, there's not always a feeler handy and was wondering if there's something else that can be substituted for it.

I managed to crack mine with pieces of aluminum cut from a soda can but that's not ideal because it tends to bend easily and usually requires a few pieces.. where I'm guessing the feeler would be stronger.

go to best buy or similiar big store, buy a cd with one of those little plastic antishoplifting rectangles on it, or just look for one of those rectangles in the parking lot, and try the little shim that is inside. Field expedient.
