Great video, LPL! Thank you for the kind words and glad we were able to give you somewhat of a challenge. It’s worth mentioning that all of our locks have similar pinning, not just the locks we send to famous lock pickers. 😃 Your critiques are invaluable and we will look into how best to address them. Looking forward to seeing what destructive techniques you have in store!

Great job on the lock. While LPL commented that the pick resistance outpaced the physical security, I think that for certain uses a higher pick resistance is more valuable and hard to find on certain form factors of locks. Two related questions for you if you'll answer. Is the double anti-bypass plates standard? And why choose that core if you need to add anti-bypass plates to secure the lock?
@andersjjensen
@andersjjensen 6 жыл бұрын
Ender Gaming The one they sent to BosnianBill also had two anit-bypass wafers. As for the form factor of the core, I suspect it is for interchangability with other body/core manufacturers.

Ender Gaming Hi Ender (great books, by the way)! 2 bypass plates is standard for our locks. We chose to go with this design as one of our first products because it’s popular and familiar. Anyone who is already invested in locks of this design can easily switch to MAKO without needing to rekey or replace all locks at once.

I was going to comment that I bet they pinned that up special. Its good to know all of your locks share this level of pick resistance. And they seem to be affordable as well. Nice! Ok, went to your channel to get a link to your website and there is no link to your website. What's that URL?

MAKO Locks, question for you. I'm a fan of this channel, as well as a handful of very similar ones, and watch them often... Also, a hobbyist amateur picker i guess I'd be considered. Anyway, since tee majority of thefts involving security devices like this are accomplished by brute force, as opposed to a more "technically proficient" means such as this, almost rendering locks w superior "pick resistance" kind of un needed, as shackle thickness and metallurgy are more important factors.... has producing an item of this quality helped sales figures for you? I and the lock sport community certainly appreciate a budget conscious challenge, but I'm curious if the consumer appreciates it as well.

Very cool, can’t wait for destructive attack(s). Of course there are bigger locks available? LPL did a series on gun locks and it was disappointing, but smart people use multiple levels as do I. I have loads of padlocks for work and firearms security, (locked cases, even in my safes) and construction. I’ve never had a work lock picked, they are always destroyed, typically by one or two hammer strikes. (Still a good idea to have pick resistance especially if it doesn’t increase cost significantly).

Yup, the manufacturer replied to me and said they always install two, to prevent puncture and manipulation. I’m guessing that if you can punch through two wafers then no lock of this type is safe from you. Looks like a well priced lock that gives you much more security then you pay for. (Against hidden attacks in any case, grinders and bolt cutters will always win).

I'd like to know your pick time on the other lock, now that you've gotten a feel for this type of lock! I've got mine in the mail, and I can't wait to get a pick in it. I really suspect that the style of serrations on those drivers are going to make it much tougher than the American 1100.. on those it is fairly easy to tell a click from a set... these looks more deceptive in that regard.

Hi LPL! Love the channel. Quick question for you! Can the MAKO Mo. 427 - Rekeyable Rectangular Padlock be raked open like the in the Bosnian Bill episode 269? I was considering purchasing some but not if they can be raked open like this. Can you test it for me? Per their website, "A vast improvement on a classic design" but to me, a new comer to the lock work world, the cores seem similar if not the same genera.

I'm sure there is a little bit of trickery going on because normally a symmetrical ball bearing shouldn't really care whether you're opening or closing the lock, right?

@CiaranMaxwell
@CiaranMaxwell 3 жыл бұрын
Serrated pins make you unable to tell whether the pin is truly set or not. Did that click come from a serration or from the pin clearing the shear line? You can't know until the lock pops open. HelpfulLockPicker likes to pick serrated pins one click at a time for this reason. Spools create counter-rotation (the core moving the other way) and possibly dropping pins. Any dropped pins must be repicked.
