[1128] A Design Flaw That Can Make an Easy Lock Hard To Pick (Master Lock M187)

    I think a better way to understand it would be to say the spring is too long or comes down too far and enters the core, rather than saying the driver pin is too short - for me anyway, it describes it better because otherwise I imagine the pin being short the other way and therefore effectively being set already and thus not being a problem - maybe I'm being weird but I understood the problem when I viewed it this way...

    I wish if he could show us how did he identify that the problem is from pin 4 😕

  • baylinkdashyt

    Sure but how did you get from "probably a short driver, lift first" to "the short pin *is #4*"?

    I remember my dad had one of these and forgot his key so he just had it opened in a few minutes with a hammer 😂

  • Demistic

    More Mastercrap. It's sad that screw ups are their best features.

  • Seraptin

    Wouldnt it be a good idea to insert two of these on purpose? Two makes it hard to push them um before tensioning...

    LOL, amazing how easy that was for LPL to open. When I was a kid my dad used this exact lock to lock our waveruners to our dock. Me being 12 at the time I of course dropped the keys in the water, and my dads friend had to come over with a huge pair of 48 in bolt cutters to cut the lock off, If only LPL was our neighbors.

    Can you end up with multiple short driver pins in a lock? If so, how would you combat that?

  • Lettu The Goat

    Hey LPL, i feel like i have the same issue with one of my locks but even worse, it has 3 out of 5 pins stuck when given tension. The pins wont go down unless the tension is let go completely. What do??

    FIRST DAY picking. 1:40 to pick this lock. I raked another master lock in 7 SECONDS. I also picked a dead bolt and door knob. Why are they all so easy? I no longer feel safe. So far I have unlocked everything I tried relatively easy.

    If a design flaw makes a lock harder to pick, it's not a design flaw.

    Is it a design flaw or build defect? Regardless, it's fun to know that their lock is only pick 'resistant' because of the defect. The marketing team at MasterLock should start putting LPL ratings on their products. 99% of their product line-up will get returned to the manufacturer and hopefully recycled in to useful things. The remaining 1% will sell like hotcakes because they work as locks - for at least 30 seconds.

I feel pretty good about myself every time that tesioner rotate's to open the lock. It's a great self-esteem booster! Thanks from Scott out of Wa. state

    How long did it take you to open this lock the first time before practicing on it? Just curious as to how long it would take someone skilled to open it without knowing anything about the lock.

    How do you solve this problem if the short pin is in position one rather than 4? I am constantly oversetting the first pin while trying to reach those in the back. 😅

    I discovered this problem or security feature while picking a Yale Y300SS/63 padlock. Pin 4 is a really short key pin and the spool driver sits flush on the shear line, the problem is pin 2 is a zero lift and the lock contains 1 serrated and 5 spool drivers. Not a fun pick once you're in false set and pin 4 is seized stopping access to pins 5 and 6.

    I think I wrecked a Brinks lock due to this. I can't even get the spool to false set anymore

  • DeviantOllam

    Neat... There would appear to be some sort of interlocking gear system connecting the tail of the plug and the articulating shackle? They appear to turn in contrarotating directions from one another.

    So to sum up, the lock is so badly manufactured that is offers some unintended kind of picking resistance?! Is this the Masterlock equivalent of a movie that's so bad that it's good? :p
