  1. I work in a factory where I’m required to use these. I get as many as I want for free, needless to say I have more then a few of these. When I got my first pick set I immediately grabbed one and went to town. After a few hours I figured I’d better do some research and see why this lock feels different. So for the 1st time I watched a video on lock lab and learned that security pins exist. I learned a ton from this site and was popping an m3 20 mins later. 2 days ago I opened an American 1205, that has 5 security pins. But today I grabbed the 1st lock I ever tried to open, a master 410 and finally turned that core. I know it sounds dumb but this lock is where I started and for months it taunted me. But now I can get them open all thanks to this video!

  2. I can not get in this one. have about 3 hours invested. I think my issue is my picks are to thick and with the warding on this lock I have trouble reaching the pins.

  3. Hi bill I started lock picking a day ago I just bought some picks out of China they are call secure pro i start practicing in locks I bought a 3 dollar lock from Walmart and picked it in 8 seconds cheap but good practice lock though

  4. I found out the hard way that if you pick one of these and rotate the core too far, the pins fall out.
    sucks, but they're inexpensive and I'll be ordering more to play with.

  5. I have never understood these locks. we used them all the time at the ethanol plant i worked at. i was looking them over and couldnt believe they used a 6 pin lock. even more surprised to see in this video they are security pins.
    the crazy thing is the easiest way to "pick" these locks is to grab the body and twist. if you do it right, you shred the lock in your hand. oh, and they also make these with a plastic shackle.
    the only reason i could think is OSHA regulations. leave it to the government to require 6 security pins on a lock with a plastic shackle that you can break in your hand.
    these are also really expensive as far as i understand.
    oh, and one more point of order, you said "they can lock it on or off, whatever position they want." most equipment is designed so that it is impossible to lock in the "on" position. locking anything "on" is completely prohibited. (i add that part because i believe you to be a person that likes to learn new things)

  6. I was working at a customers facility and one of the techs left his plastic Masterlock safety lock on the machine I was working on so I thought it would have to be cut off. Another person from the company said not to worry and walked up and put a screwdriver in the shackle and twisted the body with his hand and the lock popped open. It does not matter if it has a good core when the body is weak plastic. I would never let anybody who worked for me use this to lock out equipment. Thanks for the great videos.

  7. I heaved used these in the past in the coal mines. I don't think they are build to people out but warn or deter people from energizing something or just a danger warning.

  8. Thats pretty bad when their locks, that are made to be breakable in an emergency, contain a better pinning then their metal bodied locks. Masterlock never fails to impress…

  9. I work union construction and use these locks at work day in and day out. The big reason they are plastic is for when someone forgets to take their lock off and goes home. After following proper facility protocol to prove that nobody is in the equipment or machine, they can be easily and cheaply removed with nothing but a pair of open end wrenches into the shackle and spread apart splitting the body in half. Also, the reason for only a single key is from OSHA requirements. Each lock can only have one key, however they can be ordered where one key will open multiple locks. This is nice because then one person can have say 12 locks or however many are needed and only need a single key for them. Here is a quote from OSHA regulations "Lockout devices. Lockout devices shall be substantial enough to prevent removal without the use of excessive force or unusual techniques, such as with the use of bolt cutters or other metal cutting tools." Anything other than the one key for the lock would be considered excessive force or unusual technique.

  10. Hi Bill i have a quick question witch locks would be best to practice security pins. I've never picked a lock with security pins i can single pin pick but I have no idea where or witch locks to buy to practice please help me if you can

  11. So, I learned 2 lessons. I got me one of these. (first lock ever)
    I failed to pick it for a day. did some research.lesson 1 was learned.
    picked it.
    then lesson 2 was learned. spilled all the pins…. all over the inside.

  12. Where can I learn about these other types of pins you mention I had no idea that there where a variety of pins. I have a beginners pick set and was thinking of getting the next level of picks and was going to get a couple training locks and I seen that there are 3 types and I have no idea what they mean.

  13. Bill, Ive got a military Arms Room cage lock that is freaking insanely heavy with over a 1/2" arm that sets inside the steel when locked. I'm sorry I do not have it in front of me for a name or anything. If you know what I'm talking about, have you ever picked one? if not Ill dig it out and post a pic somewhere.
    thx and Merry Christmas

  14. Hi Bill,
    Just started lock picking and really enjoy these videos! I noticed an EOD badge in the corner of one. I went through Indian Head in '66. Any way I can send a PM? Thanks! Rob

  15. Thank you bonsianbill !!! After watching your other videos I was able to make my own tension wrench and pick and successfully open one of these master locks with a blue casing without watching this and never trying any lock ever before :)

  16. Being an electrician, working in alot of the industrial plants in Detroit, This bad boy is what were are issued on the job. The primary reason that they are plastic is there are no "master/command" keys and they are only issued with one key. So if the Electrician, Millright, Pipe Fitter etc.. leaves the project without removing their lock (or loses the key), it can be taken off eaisly to allow operation of the Thingee getting the plant back in service. typically if you leave the job without taking your lock, youre going to either get called back to remove it, or if they have to remove it, your going to get fired. Either way a LOCKOUT lock only has one key, wether it's plastic, or metal. (I've got both types)

  17. Haha we have those loto locks at work, no one ever uses them though, is there any difference in color? I have red ones but ive seen a few blue and green ones on equipment 

  18. It would seem to me that if Master lock used a steel or brass shell on this type of mechanism, they could market this design as a pretty high quality (compared to most Master products) standard/general purpose lock.

  19. The 6 pin ness and security pins are likely to prevent accidental 'coincidences' of locks and keys, so each person can ONLY remove their own lock. (That'd be my guess anyway)
