Assa Fingerpin Tool (the "Magic Finger Tickler")
Description

This tool is filed to perfectly fit horizontally inside the bottom of the Assa twin keyway. It's curved design allows the pick to "scoop under" the finger pin and gives you a little extra stroke when lifting upward via a rotation of the tool. Future versions might include scratch marks on the shaft to indicate alignment with the finger pins. The edges are filed to a knife edge to prevent snagging.

Uses

This tool is useful with the Assa Twin, and Assa Combi type models of Assa locks. Does not work on the V10 due to its smaller keyway.

Directions

There are a couple of ways you can make this. The path of least resistance is to purchase a cheap Dimple Pick set from banggood (these are great for making custom tools). You can chunk one of those tools in a vise and using a file and/or a dremel to cut and shape. Additionally you can heat the metal and put a slight curve in it (using pliers and a nail).

Mul-T-Lock Inner Keypin Tool
Description

This tool was made initially for the Mul-T-Lock MT5. Its thickness, width, and height was specifically designed to work with their Pin-In-Pin system. It allows the pick to slide under the key pins, rotate and slide upward inside the outer keypin and lift the inner keypin its entire range of motion.

Uses

This is useful on any Pin-In-Pin system I've ever come across. It is possible this could also be used on sidebar pins of other locks, such as Assa, but it obviously wasn't designed for that purpose.

Directions

This involves a cheap chinese dimple pick and some TLC with a dremel, fairly straight forward.

Mul-T-Lock MT5+ Fingerpin Tool
Description

This tool was made to fit vertically inside an MT5+ keyway, between the finger pins and the keyway wall without moving them, while providing enough stroke to slide the finger pins their full range of motion. The edges are filed to a knife edge to prevent snagging.

Uses

This is useful on the Mul-T-Lock MT5+ fingerpins only.

Directions

This involves a cheap chinese dimple pick and some TLC with a dremel, fairly straight forward.

Medeco DCAP Tool
Description

This tool was a small modification of an existing pick to replicate a much more expensive retail tool. It's designed to assist in rotating beveled key pins, such as Medeco and Emhart. It does this by grabbing onto the chisel-tip keypin, allowing you to rotate more easily.

Uses

This tool is useful on Medeco and Emhart locks. Keep in mind that there are many Medeco keyway designs and this will not work on all of them. This specific tool works well with the "Air" keyway. Different keyways may require you make this from thinner material.

Directions

The path of least resistance is to take a Southord Short Hook (or equivalent from another brand) and use the thinnest dremel cutoff wheel you have and cut a small groove in the tip of the hook. It's helpful to carefully bevel the groove into a slight "V" shape, although that's not required.

Dimple DCAP Tool
Description

Similar to the Medeco DCAP tool, this is designed for use in smaller profile locks, almost dimple-lock in nature. It also has the DCAP groove, just smaller.

Uses

This is useful in Medeco Camlocks (not to be confused with Duracam). Although success is hit-or-miss, it's also been useful in manipulating Primus fingerpins.

Directions

This involves a cheap chinese dimple pick and some TLC with a dremel, fairly straight forward.

Medeco M3 Tension Tool
Description

This tool was specifically designed to work with the most common Medeco M3 keyway design. It works as a TOK wrench and fits around deep inset warding.

Uses

Medeco M3

Directions

This started out as 3/16" Weld Steel Round-Stock. I put it in a hydraulic press to flatten both sides, ensuring the flat edges were parallel. I kept pressing it until the width was within a few thousanths of an inch of the desired final width. I then heated the steel with a torch and used a vise to bend it into a common Prybar shape. Cut it off with a hacksaw. I used a flat file and a caliper to slowly shave off metal until the overall width was perfect. Using a permanent marker I marked the tip of the wrench and pushed it into the keyway and moved it around so any warding would scratch the ink. Using a dremel to slowly eat away on the wrench until all the grooves were cut to wrap around the warding, I kept repeating this action until the wrench went into the lock a satisfactory depth.
