Master #175 Combination locks

Thanks for the info, I will have to play around with these locks a little more, try to find the other bypass methods.

There are two known bypass methods. The one you already know. They both accomplish the same thing (lifting the lockplate tang out from between the locking dogs. The second one involves the use of a Weiser shim pick, or the Peterson mini knife. Insert the tool along the right side of the number three wheel, angling it downward over the top of the axle, and aiming toward the middle of the lock body. Now depress the shackle, as you lever the tool upward against the lockplate. If you're in the correct position, the lock will be open as you release the shackle. This method takes a lot more practice, and patience, as the clearance for the tool varies from lock to lock.

The first method (using the hook pick) is by far the simplest and quickest, but if you're opening a customer's lock, the second is harder for them to duplicate after they see it done.

True, that second way, more professional, won't be done as easy after they see you do it.

Ok managed to bypass my 175 but broke my pick trying to do it a second time. At least I know I can do it.

I bought one of these locks recently and none of my picks are small enough to fit beside the wheel. maybe master made the tolerances tighter due to the bypass? or do I just have fat picks

indeed they did.
the easy way to tell if you have a bypassable one,or one of the newer ones,is the newer ones bear no"master"
or "175" on the bottom beside the wheels.
the older, bypassable ones have the lettering stamped quite clearly.
also the pawl spring is much stronger in the newer ones,making the top-of-the-wheel hook
bypass to lift the pawl much harder without a custom tool made from feeler gauge...
(thanks Ken Pearson for that tip.)

Kinda late here, been meaning to post this cutaway lock back in 2008 when I joined. Perfect opportunity though.

I know this isn't the same model as the #175, but hopefully someone gets something out of the visual. The feeler gauge in this vid is .010" thick, and works great on the old models. Since the newer locks require thinner feeler gauge material, I find this hook design works better for me personally.



Man, I'm getting fat. Hope this helps!

Excellent video Decoy. Thanks for that explanation.

Great Video man! Always nice to see a breakdown of a lock like that, great job!

I don't know why it's not appearing. The notation looks good... just chill out and copy/paste the url into your browser's address bar piepie. It's still there.

Bruno2260 has a couple vids on bypass methods also. One shows the feeler gauge method and one very clearly shows the hook pick method. As for bent picks, I've never had any problem using the hook pick method.

i have opened them without bending picks... but then again... i have bent picks trying aswell... i find it harder on the newer ones... more likely to bend the pick...
