Proposed Pin Tumbler Bypass Technique

[Lokka]

i had this idea :D
it will probaly jam the lock after its opened once but anyway.
it could be made out of wood,
the idea is that all the pins are pushed under the shear line at once before
turning the "pick", it vould cause the pick breaking an leaving a small bits of wood
in the lock, but hey, its opened. now ill draw the picture.

Like a comb pick?

so the red is the shear and breaking line, when turning this pick,
the boken parts wil stay under the shearline with the pins, and the plug will turn. maybe =D

i love this thread, i would suggest useing an acid to cut the lock, also i have had succses with a tool i call brute force, i just have to make one that dosent break off into the lock.

So here's a strange one for you... back a few years ago in my freshman year of college, a buddy of mine discovered a way of bypassing locked dorm rooms in my dorm...

*preamble* Mods, I apologize if this is restricted since it pertains to unauthorized entry, but it's 1. appropriate for the thread topic, 2. harmless at the time performed, 3. not performed by me, and 4. a challenging concept without an obvious explanation. </preamble>

Shrub: Illegal activity and bypass method removed, you need to take a closer look at the rules of the site,

How's that for a bypass? Strange huh... I never could figure out how it worked, but I personally saw it done multiple times... even to the same door.

(there was no theft or anything... just part of the mischief everyone was getting into... harmless, but not necessarily moral.)

There is a lot to think about in this thread, during my time as an apprentice locksmith we were mucking around with ideas. We were at the time in the machine shop and thought to use water!!!

We would spray water into the cylinder and then using liquid nitrogen and or freezing spray, spray the cylinder while holding up all the pins as high as possible.

Then applying a little heat by a soldering iron fitted with a thin wire just tried to heat the bottom pins, when they fell we forced the cylinder and opened the lock.

It worked most of the time and on most locks but they had to be in very good condition.

just to keep in mind to guys most locks "cylinders" will not have enough space in the chambers to have the spring, top pin and bottom pin above the shearline. Even with the spring completely compressed. However they still can be defeated if the combination is correct. ie if all the pins are less than a 5 depth.

There are however many padlocks that are favorable to this type of defeat, I use combs on alot of padlocks along with shimming the front of them. Alot of the asian padlocks can be done even tho they have a ridge in the front of the cylinder.

They really have crappy tolorences and therefore plenty of 'room to move'.
