  • Here's my approach to bypassing deadbolts with an Under Door Tool (UDT).

    Formerly called the Mule Tool it is a favourite among government agencies because it allows to surreptitiously enter a house or office. The MPGET, Multi Purpose Government Entry Tool comes with various lengths of extensions and attachments. It can open levers, knobs, thumbturns and pushbars.

      Yep--that's actually where I got the idea. Its definitely easier to perform a wider array of attacks with the kit shown in that video.

    Would love to see someone do that from the other side of the door?! I use the UDT all the time and it's difficult just popping a Lever handle. You'd probably need to use your phones camera- under the door- to see what you are actually doing. Or have X-Ray vision.

      I had to develop a protocol to catch the thumb turn consistently. Using a methodical approach and the insecure side lock face as a reference, It is difficult but achievable. The original mule tool had an attachment that supposedly made this easier but I've never attempted to recreate those accessories.

    Disclaimer: I used a "morph cut" at 1:03 because, after successfully opening the latch, I paused for a few seconds before opening the door. I made this cut to keep the video moving at a faster pace and because I didn't want to re-film the technique, hours later.
    I mention this because this editing technique could be used deceptively--I want to be transparent about that. Most of us know that a lot of lock picking/bypassing videos out there have been filmed deceptively to make certain techniques appear easier or even possible. This technique certainly isn't easy or fast. However, my intention in creating these videos is to demonstrate lock bypassing concepts in an engaging way rather than to create a portfolio of my own skills and abilities. For that reason, I believe the use of this cut is appropriate.

    At first i was like when would you ever be able to do this. Then in the second shot he is at an "inside" door and i was like oh okay, not an outside door... Then i kept thinking about it.... And i still dont think this makes sense. The second door looks like it was assembled just for this purpose. I guess maybe some bathroom doors? Idfk they would have to be pretty old and it would still be weird to have a key'd bathroom. Like maybe in a public restroom like a 7 11 but they don't have gaps around the doors. I cant imagine this being a skill that is ever useful in america

      It's true that exterior doors often fit too tightly for a UDT. But you'd be surprised how often you'll find doors that are the exception. Also, air bags will occasionally provide just enough lift to use a UDT.
      It's true that the actual door is not a typical US exterior door. However, the thumb turn, if anything, is MUCH harder to move with the UDT (compared to the thumb turn on a typical residential dead bolt).
      So this example doesn't mirror the ideal US residential environment but I'd argue that it's certainly a valid analogue of the real world.

      @@ContingencyLabs airbags* that would make sense. Also having recently modified an exterior door I found that there was a gap that was filled with a slide on rubber seal. It would definitely compress. Although there was also a concrete lip behind it so this still wouldnt work. But the building I live in is not normal. I will start looking a little more carefully now. I have actually, at times before, just pried the door way open enough to slip the door open and bypass the deadbolt with it still locked. I still havnt bought or made a UDT yet as I havnt seen enough occasion for it to be usefull enough to warrant such action. But the airbag idea is intriguing

      You mean a Kwikset Smart Key? This is a bypass that is not generally affected by the design of the keyway.

      Nope but it was stupid difficult on that tiny thumb turn. Nevertheless, this was a technique that was advertised and taught by the original manufacturer of the mule tool. But it's not hard to see why this technique became obscure in the following years.

      @@ContingencyLabs I’m assigned to open a Samsung SHP-A30 lock. Was looking for any non destructive bypass. First of all, youur method won’t work because the standard UDT won’t be long enough. And the first example you showing is coming from the side. That’s a joke . Almost like hitting a lottery when I open it with this method. 😂. Any suggestion on bypassing fingerprint and numberpad smart lock with no external key access?

    This has to be a joke. Just to see what kind of responses you would get. You could barely unlock the lock from the same side with that tool. Please don’t waste your time trying this.

    • @ContingencyLabs
      @ContingencyLabs  ปีที่แล้ว

      You're definitely correct that it's (1) very difficult and (2) not very practical. But I wouldn't say that I can barely open the door from the insecure side--the mechanics of the tool are just awkward to freehand without the support of the door's face (it's a wobbly metal rod, after all).
      This video wasn't posted as a joke. Just a demonstration of one of the techniques that was originally demonstrated when the first mule tool came out. You don't see it demonstrated much because of the aforementioned difficulty and speed issues but it was interesting to try.
