  1. Dear Bosnianbill!
    I'm highly interested into if a new Abloy Novel 33*33 cylinder lock can be defeated by using this or other methods?
    I'm planning to buy a lock and I want something that can't be opened without the key or it's extremely difficult.
    I heard about the Tokoz Pro 400, I would highly appreciate if you could say something to me about that as well.
    Thank you! :)

  2. Hey bill, do you know if this sort of bypass works on a protec cliq? I've been trying to pick it for ages but as you said no can do so wondering this this might work?

  3. Well, you sold me on Abloy because at lease I would know someone was in there. Security is now always what someone takes, but what they leave.

  4. Hi, finding your videos fascinating to watch. I spent 15 years (the entire 90s) working at the University of Kent in the UK as a carpenter. In the course of my work I also got to work on locks, Abloys especially were fun. I had no reservations about working on them because I knew they were so well made. This didn't stop at the core housing either. The rest of the lock was just as durable, almost armoured. So, though your demonstration above shows the lock failing, in reality, all you would do is crush the mechanism against the side of the main lock body making it inoperable at best. Liken it to a cop shooting a doorlock open. Nothing will move inside if it's mangled up. The bolt alone on some of those locks from the 80's were nearly 40mm tall and 10mm thick. That's a big cavity within the lock to be expected to slot back into. So by its destruction this lock will still keep you out. I know

    Just out of curiosity do you ever pick chubb dead bolts and the like?

    On an aside, after moving to France I had the privilege some years ago of adapting old keys to work old dead locks, some of which were several centuries old. At the time I worked on the restoration of the house of an antique dealer and mentioned I had experience with locks. After that I got to make keys to fit his locks. Did about fifteen in total and loved every minute of it. Finessing an old rusty key to fit a lock that hasn't been unlocked in decades, maybe longer, does give you a smug sense of satisfaction. Makes me smile seeing you use such delicate picks. A bent four inch nail would have been adequate for these old locks LOL! I took photos if you'd be interested in seeing them. Anyway, huge thanks for your vids. Yes, I have subscribed.

  5. Other than the cam lock, every other iteration in the Abloy range does not have an open space behind the core to permit its removal in an assembled installation. Also, the brass and copper retainers are not used in later designs. Pointless to attack the core this way. In any event, if the core was dislodged from its housing the components would drop down into the lock assembly and most likely interfere with the latch or bolt assemblies. Much simpler to drill for manipulation points.

  6. Abloy doesn't address this issue because it is probably how a locksmith is supposed to compromise the design, due to the soft brass piece purposely being soft brass.

  7. Abloy locks do not have 16 discs … they have 11 key discs and the rest are thin spacers that make up the disc pack.
    Abloy also no longer uses soft retainer rings to hold the disc packs in.

  8. you cant break it if the lock is installed correctly it doesnt have space to "move" the internals of the lock fully.
    The lock bar still stays in well atleast 50% of it stays so it cant turn and as most Abloy locks are nowdays 100% stainless steel it is unbreakable only way to fully break correctly installed Abloy lock is by breaking the door

    1. Actually, you can drill through the abloy, but it is a damn pain in the butt to do that.

  9. Interesting, I know of an application that uses those locks and has enough space behind them, that'd let the core be punched out. Thing is with the Abloy cam lock properly mounted, does the tongue prevent or limit the core movement. It's also got me wondering if Bilocks have a similar weakness.

    Thing is, in the application they're used in, the door's the weakest link and the crims know it and attack that instead.

  10. I thinks that will be very hard to do in a real door, because the door or its frame will move and absorb part of the applied force with the hammer. Also the noise, the real thing of picking is to not damage, and pass without anybody noticing the entry.

    1. You are absolutely correct.

      This type of lock can be found on letter boxes especially on aluminium letter boxes. I tried doing this and it bended the letter box cover. The other issue is there is normally a back end screw which I think if fastened correctly, will not allow this method to work.
