  1. Dear Bill I'd really like to purchase a basic lock pick kit but can for the life of me find anywhere here in the UK that sells them. Please could you help me out buddy. Here is my email, incase you can help. Many thanks for your great interesting videos. Charlie Green. Email is charliekp239@gmail.com

  2. Can you make a video of how pins work? I am interested in why there are some designed differently than others and how each design works. I am also interested in learning the terminology like "false set."

    I've been watching you videos for about a week and am still confused about the terminology that you use. Great videos though!

  3. Hi bill , Im looking for the best chain + lock on the market , it will be used to secure a Motocross bike to the ground , price isn't an issue , what could you recommend? Thanks

  4. I'm wanting to start lock picking as a hobby but I don't know what pick set to get. I live in the UK so I think I need slimline (0.015) picks. Is it worth splashing the cash on an expensive lock picking set? Or are the cheap ones just as good? Is there any slimline pick sets that anyone can recommend that aren't more than £20 (that's $26-$28 I think).

  5. Great videos as always, iv started to make my own videos on youtube but im having some focus issues on my Sony dslr camera, can you give me some advice. And also since i cant order any lockpicks iv made some myself. Some are shown in the videos, thoughts?
    Thank you in advance!

  6. Hello, just got lockworking as one of my new past times, very green at it yet. Picked a few pin tumblers, made a neighbour hysterical using your joke on cheap chinese disc lock – all fun. But – we have a lot of old style locks here with flag shaped keys with a 'flagpole' part up to 10 cm tall and the main part about 2-3 square centimeters. Usually a 2 sided key.

    So an array of newbie questions – what's the proper name for this lock type (pretty traditional one), how are they picked and what are the tools needed.

    P.S. despite being old type, lock of this type was the only one of the four on my neighbours doors that actually withstood crack attempt long enough, driving burglars into enough work enthusiasm to get detected.

  7. What's the point of having different shapes pins? Ai standard, asa (sp?), serrated,  spool, etc. Being inside a tight cylindrical prism with back pressure of a spring, what difference doest he shape make? Unless it effects the spring or I'm missing something entirely. I must be, otherwise I'd probably know. Please let me know.

  8. Hi Bill,

    I was wondering if you could give me some advice.

    I've been practicing picking locks for a couple of months now, and I've been able to get open every lock I've tried so far… except for my Master 192D.
    The problem I'm having is that, due the way my key is bitted, the first pin has to be left all the way down while the three in the back have to be lifted a couple millimeters. The keyway is very small, and when I apply a bit of tension to the core the first pin locks up to where I can't move it at all, and I don't have any picks small enough to fit through the space below the first pin (which is only about 1.5 millimeters).

    I've tried putting the pick in and then applying tension, but I still haven't been able to get it because I just can't maneuver around inside well enough. I have bent up my picks quite a bit trying to get it open and I'm out of ideas now.

  9. I'm so interested on this one. I have couple such locks in my nasty bucket. After taking one apart I'd expect serrated and assa style pins with some countermilling. Those are quite a challenge even with stock pinning.

    Now, I'll watch the video, I'm commenting before seeing how you'll probably open one in 2mins and find some alien technology inside instead of the standard one giving trouble at my skill level :)

  10. very nice picking.
    the second last pin isn't quite a standard. It has beveled edges. In my experience , they give very little feedback.

    Johan , are the depth and spacing specs for these the same as for ASSA ?

  11. Nice banana their Bosniabill where did you get the Don Henley "double headed bleach blonde" ???? is the head dead yet. you know the news room has a running bet…

  12. Any chance you can hook me up with a beginner pick set and locks…lost my job and need something to do inbetween job hunting and the such

  13. I've never picked a lock in my life, however I find your videos fascinating. I watch them like looking at a magician doing his trick.
    This time I think you've mixed up the pins (look at minute 7:00 and then 7:30).

    Anyway great work! (as usual), thanks for uploading them.
