Showing why some Master Combination locks M175 can NOT be bypassed by lifting the internal latch. It can still be picked open like most combination locks by feeling for the deepest groove in the inner rings or dials.

If Master Lock would make a design without the deepest grooves in the inner rings then this lock would be pick proof as it can not be bypass, picked or shimmed but lets be real, we are talking about Master Lock Company.

I also made a little mistake in this video: once the correct number is dialed in and the inner grooves are lined up, that latch does NOT fall into the grooves by itself. You have to pull on the shackle that will push those 2 bearings towards that latch pushing the latch into the grooves and the lock is opened. Hope this is clear but if not, let me know. I will make a new video. Thanks
