Two Open Source Projects Combine to 3D Print a Working Replica Key Using a Flipper Zero

  You could already do that by just taking a photo of the key, or using a pen and paper, or press it in a piece of cheese. Basically, half of the stuff one already has at hand could be used to achieve the same goal.

  Also I am glad that my keys/locks have security features from the current millenium. Makes it a pain to pick or duplicate (yes even non maliciously, the local locksmith needed to order specially stuff just for me lol)

    Do you care to share what special type of lock you use?

      I wasn’t able to find it online. It came with the house.

      It is a flat key that has normal teeth on the edges, two rows of small teeth on the top and bottom and two balls that can sink and rise, one large one small.

      You could look at Bowley. They have a fairly pick resistant/proof lock

  Most locks don’t really keep people out. They just keep honest people honest. At best, they slow an attacker down and/or make it more obvious.

  This certainly doesn’t make me want a flipper any less than I already do. Seems so fun to mess with

    After pen testing a home network it becomes a novelty item.

    Turning off TVs and opening Tesla charging ports is fun for a bit.

    The best, though, is setting off the department alerts at Walgreens, there’s a lot that exist that the employees have never heard. When you trigger “help needed in the baby department” then watch the employee reactions it’s a fun time.

    Beyond that, it’s a paperweight most days.

      I have a buddy that uses his to spoof people’s apartment swimming pool access cards.

      Ngl, I use mine almost every day.

      My car is old enough that I can replay with no desync, I use it to keep my car running and locked when it’s cold and I pop in for some food on break at work, or if my remote dies; it has every remote in my house in it, xbox one, my living room tv, my bedroom tv, my workshop CRT with the lost remote, my ceiling fan, and can be used on all other IR or (almost all) subghz devices I encounter; my local bar was real loose with the touchtunes remote one tuesday afternoon when I totally wasn’t in to copy specifically that (I gave the bartender rides home when she had a DUI, they’re cool with me) and I was able to copy it, now I can control the volume outside (among other things but I’m responsible with my powers, I only skip Rick Springfield and Don McClean); a couple of my friends no longer need to worry about giving me keys when I feed their cat because RFID, and I “have” a gym membership now (the gym allows sharing, probably not specifically cloning but they’ll never know); I can send myself Pokemon Silver mystery gifts on the GBC, and I have a GPIO board with a link cable to trade pokemon in too; marauder/evil portal is a little too malicious for me but it’s neat, and flipperHTTP is cool too; some of the GoodUSB stuff is cool; I have a 2gb flashdrive image on it I can use in a pinch; and tbh I’m sure there’s more I left out.

      Though yeah “we don’t even have a baby dept in this location” and “since when are our CVS announcements in spanish?!” are priceless lmao.

    It was nothing more than a novelty after about a day and a half, even with the WiFi module.

    Think of it like one of those 3-inch swiss army knives, but for IR tech and radio. If you mean to do work. Use the correct tool for the job, but there is no reason you cant acomplish what your trying to do. They are great for learning, if I was teaching a kids about cyber security, a flipper zero would be on the required tool kit.

    Yes, you can do harm with them, per the previous analogy its still a knife. However, devices not hardened against simple replication attacks or brute force acomplished by something barely more powerful than a TI-84, those manufactures and customers needs to take the security of their products more seriously.

  the key is laid flat against the Flipper Zero’s display and the depth of each cut on the screen moved to match its physical equivalent. This provides a series of “bitting” numbers, which can be used to cut a working copy of the key.

  Neat!

  This jams the lock!

  • cynar@lemmy.world ⁨1⁩ ⁨week⁩ ago

    It would work a couple of times. It’s just not a long term solution.

    • bluewing@lemm.ee ⁨1⁩ ⁨week⁩ ago

      Only if the lock isn’t worn or dirty on the inside. I wouldn’t trust this for any outdoor lock or older lock. Even cheap locks with poor fit and finish causing rough operation would not be a good idea. This is a fun gimmick that could easily cost you more money than it’s worth.

      The only way I might use it is if I were to use the 3D printed key as a pattern to cast a metal one. And I ain’t got time for that.

  Im interested in how a flipper can help? Is it some app that tells you how high the pins are?

  source

  • rebelflesh@lemm.ee ⁨1⁩ ⁨week⁩ ago

    Yes it has a key copy feature, it’s a key graph.

• AlbinoPython@lemmy.world ⁨6⁩ ⁨days⁩ ago

  The 3D printed version could, however, be used to create a mold to cast a more robust replica.

  Here’s one way to make a mold.

  I saw the video too and I found it somehow stupid to 3d printing a key when you can go to locksmith Image

  • acutfjg@feddit.nl ⁨1⁩ ⁨week⁩ ago

    How many people know a locksmith versus how many people know a 3d printer?

    • LastYearsIrritant@sopuli.xyz ⁨1⁩ ⁨week⁩ ago

      You just need a picture of a key, a key blank, and a file.

      It’s always been extremely easy to copy standard keys.

      Yes, this automates some of it, but honestly if you’re smart enough to know how to use a flipper Zero and a 3d printer, you can cut a key by hand (assuming no disability prevents you from having fine motor skills)

    If you’re copying keys like this, you probably don’t want a paper trail or additional witnesses.

  • janus2@lemmy.zip ⁨1⁩ ⁨week⁩ ago

    if you have a 3D printer it denies saves you a trip to the hardware store

    plus you could print fun… novelty keys. ( ͡° ͜ʖ ͡°)

    you could even print them from dissolvable filament so that if your idiot guests lose them outside they’re likely to dissolve in the rain

    or maybe there is such a thing as self destructing filament that doesn’t require water? like some kind of heat activated depolymerizer that takes a few days to break down after printing. that could be really useful for like an AirBnB
