Several years ago I started Lockpickers of New Jersey after meeting Deviant Ollam at HOPE. As of January 2016, we are a full fledged TOOOL Chapter. Our meetup page can be found here. An imgurl album of the progression of our journey as a lockpicking chapter can be found here -- I update it with new images once in a while if we get new or unique gear. We can be followed on Twitter @TOOOL_NJ. Stay tuned for more updates! :-)

Bypass Tools - The Mule Tool

            In the video B and E: A to Z, we see an individual describing a Mule Tool, and it's use. A Mule Tool, otherwise known as an Under The Door tool is a tool used to discretely or covertly open a door from the outside, without the use of lockpicks, and without leaving much of a trace that the door was opened at all. (Screenshots and a video capture will be here at a later date)

            In the above video, the individual shoves the tool under a door and with clever manipulation of the tool, opens a door from the outside. There are variations of the under the door tool these days; and they are widely available; usually only to locksmiths. The most common is the Keedex K-22. It is fairly inexpensive, and mostly just various pieces of metal and steel wire strung together. This tool is made primarily for lever doors, but variations exist that can open knob doors. Photos here, along with measurements courtesy of Fenwick23 on Reddit. (Thank you!) Also, measurements & other info.

            Despite the difficulty of obtaining such a tool, occasionally they do show up on the Internet.

            I don't know the origin of this tool, but it has always fascinated me. Unfortunately, most tools like this are hard to acquire unless you are licensed locksmith. Information is equally sparse because this tool is so coveted. If you make a forum post about this on lockpicking101, the thread will get closed. It also only gets talked about in places like Lockcon. I believe making this knowledge public can only increase security for those in need.

            If you happen to have one of these tools and are willing to part with it for a short time, please get a hold of me. I'm looking to do research on the variety of tools like this to present at HOPE in the future. I'd like to get my hand on a variety of these tools as if at all possible.

      User Blakhal0 from Reddit created his own Mule Tool from the instructions I provided and linked to. You can see it on his site here.

            Here is a comparison of each of the tools I have. The bottom is the stock K-22 Under The Door Tool. The one above that is one custom designed by Blakhal0. The top one is a letterbox opening tool. similar to what is available here. The rubber band side is used for turning a knob. These seem to be common in the UK. It is designed to fit through the letterbox &/or the peephole of a door.

            The K-22 under the door tool is designed to be shoved under a door with a lever lock. Typically, fire & ADA code dictates these types of setups in schools, hospitals & commerical buildings. There are also kits out there to design & build an under the door tool by yourself with some basic materials. An example of a PDF showing how to put together, design & use such a tool is available here.

            I'll be creating more under the door related media & will be coming up with my own design soon, complete with photos. In addition, look forward to a video & an example of what it is like to properly use this tool, along with my thoughts & experiences. For the second under the door tool I have provided by Blakhal0, I will probalby use paracord unless I can source metal wire cheaply. If you have any bypass tools you'd like me to review or try to research more information on, please shoot me an e-mail.

Ultimate Handcuff Key

I haven't seen anyone else go about posting the file for this, but here is the Solidworks part file if you wish to create the ultimate handcuff key yourself. You should be able to convert it to the correct open source formats if necessary. Note that this is using the exact specifications listed here:

NOTE: If you come up with a working version, or an improved version with some changes, please e-mail me the updated file.

/r/lockpicking on Reddit - I spent most my time here, and exchange locks, picks and ideas with other members. My ideas, thoughts, and success/failures can be found there prior to being posted on this site.

The Amazing King - Jon King's website - tons of information here, security, lockpicking, cryptography, and so on. Extremely knowledgeable guy on locks. Occasionally on /r/lockpicking as well.

Keypicking.com - a great forum community. Some members also visit /r/lockpicking on Reddit.

LockpickShop.com - An awesome lockpick website. I've given them quite a bit of my business and will continue to do so. Based out of New York. Fast shipping, great customer service. High quality picks. This site got me started on lockpicking.

LocksmithArmy - A website ran by one of the users from Keypicking.com - some awesome links here and references. This site motivated me to build this webpage to showcase my interest. I highly suggest checking out the links on their site.

Blakhal0's blog - A fellow Reddit user's blog going into some nice tear downs on how certain bypass tools work, how to build your own, and so on. Awesome stuff here, and constantly growing. Thanks for the link blakhal0!
