Compromising The Master Padlock

[Big Jesse]

Ok guys. This is something I've been working on, I figured I would post it here before I start handing it out to people I teach in Austin. Id rather it came from me than them.

There is a lot of knowledge and talk about how to open a lock. But I have OCD, and I think in terms of 'lists', not banter and conjecture. We all know a pad lock can be defeated easily with bumping, and picking, and over lifting, but i have yet to find a comprehensive list for Non Destructive and Destructive entry techniques available, just for this particular pad lock.
I realize this doesn't pertain to ALL master lock pad locks. And within the recent year, master lock has made it impossible to shim a lock alone, or use a master switch on a lock alone, but now BOTH techniques must be applied in order to retract the pawl enough to release the shackle. but i feel this list is decently comprehensive for teaching purposes, in developing a strategy for defeating this pad lock.

In defeating a lock, one should not resort to Single Pin Picking Methods alone, unless that is your intention due to sport or hobby. However an operator or locksmith should have multiple techniques and tools at his disposal, as it relates to that particular lock, and execute each technique, for a limited duration... i.e. if you cannot rake it open in 30sec, move on to the next technique, and so on.

The idea behind this strategy is to not spend 30 minutes using single pin picking to defeat a lock that is just defeating YOU. This strategy is allows you (depending on time, and equipment on hand) to move form method to method in an orderly fashion (ideally from quickest and easiest...to more time consuming and more practice needed before application)

Some of these techniques you may not agree with, but its all scenario specific and dependent upon mission parameters. Regardless, these are all the techniques that I know of, to defeat the Master Padlock, specifically #1-7.

Criticism is appreciated, expected and welcomed. Additions are welcomed!!!

note: the only method not added is "popping the cap" which is used to pop the top of a bible, of a cylinder, releasing the pins and guts, allowing you to turn the cylinder, i did this because when i was a locksmith, masters 1-7 had solid bibles, and were not rekeyable, however, if they are rekeyable, or if a '1-UP' master pad lock can be rekeyed, and the top of the bible of the cylinder can be removed, then I was just unaware of it then and now. please let me know if the top of the cylinder can be removed on any of these and I will add "popping the cap" to this list, but in the destructive entry section since you are altering the structural integrity of the lock itself, thus making it inoperable.

There can be no discussion of destructive entry of any locks outside of the advanced forum. Please limit the discussion to non-destructive entry only, people. Also, bypass falls into the same category at this time.

Thank you,

Gordon

P.S. Look forward to seeing what methods have been used by members here.

"Compromising the Master Padlock" is this not a redundant statement? When I think of a master padlock I think of a person who wanted to check a box for insurance purposes, secured.

I agree totally with that statement. My first book on lock picking really hit on the anyway you can open a lock is the real purpose.

I know we can't talk about destructive methods but would it be awesome to see some pictures of these methods together in one thread!!!

So without bashing master lock too bad because of what they did to the american locks...

bahaha. this is just a concept of strategy. you see im putting together a curriculum for local company to teach covert entry for... my curriculum is below...

.....................

So the purpose of this particular list, is so any operator or team member, after having performed proper reconnaissance of a lock and door, can go through a book (my book), and pick out that lock, and know... based off of the book's info provided, that it can be defeated 18 different ways Non Destructive and 12 different ways Destructive, and I would have recorded times for each method of entry, so he can report back to the team leader, the particular method that will be used, and how long it may take to do it, and the team leader can give him better time, sound, etc parameters before the execution of the mission.

however, the 2nd portion of the strategy would be for the operator to prep for 5 or 10 different methods of entry, depending on his preferences and mission parameters. then attack the lock using said methods.

it all starts with this list.
this will be one lock, one list, in a book of every master lock on the market, with their own list of compromises and ways to defeat each lock.

I like it!

I would love to take your class!!

Thank you, unfortunately putting together enough materials for a whole class is really darn expensive lol, thank god for H.L. Flake lol. my goal is to have enough hardware, tools, and everything on power point ready in 3 months, for a class of 3 people and 1 instructor. my 6 month goal is 5 people. however, i cannot teach this to more than 5 people without an assistant, and hoping jgor want to step in with that, but havnt heard back from him.

but the class isnt running just yet. hopefully this summer.
but theres not much you dont already know, what i teach that isnt being taught is strategy as it relates to operators and missions. everyone can learn how to pick a lock, but few know when to apply it appropriately. thats my opinion anyways.

and im not a spook or pretending to be something im not. i got an offer by the owner of the company that holds my current commission-security officer license to teach at his new school house that opens this summer. i dont do this for a living like BosnianBill or MBI. those are the real OO7s!

Consider adding "knocking." Never tried it, but I've seen youtube videos: place master lock on a hasp. Pull down hard on the lock. Hit the side of the lock with a hammer several times (to walk the locking pawl out of the shackle). It will open.

For the destructive entry side of your idea have you considered speaking with your local Fire Dept to see if it would be possible to burrow equipment, or possibly buy old equipment. It would cut your costs, and may also be able to work out a deal to teach the non destructive side for use of their destructive tools. Working in the Emergency field you would be surprised how few people in a lot of departments know anything about Non Destructive Entry.

Generally as a first responder we can use what I would term "Least Destructive Entry", there are even times when we can wait for a key-holder or even a locksmith to respond for entry. Otherwise with the resources that we have an entry can be made within the time allotted for a proper response.

"Least Destructive Entry" can often be very simple things like cutting the first link next to the padlock in a chain securing a gate thus saving both the chain and padlock for reuse. No part of what we do involves damaging property to any extent then is absolute necessary for the task a hand.

Other times we may have spare keys in addition to the Knox box system, this is all part of the preplanning and code requirements that are required in most districts.
