To better understand this, let us briefly review how a pin is set on a simplified lock. As we can see, we set the driver pin by first binding it with rotational torque on the plug and then raising it to the shear line. Upon reaching the shear line, the pin breaks the bind and sits on top of the plug—thus "setting" the pin.
What is the purpose of security pins?
This is the purpose of security pins, to take everything we as lock pickers have acquired—our knowledge, our experience, our techniques, and our developed sense of feel—and plot it against us. So is this the end? Are security pins where lock picking goes to die?
What is a spool pin in a lock?
First developed in 1865 by Linus Yale Jr. (founder of the Yale Lock Company), the spool pin – due to the simplicity of its design and the ease of manufacturing it – is the most commonly used security pin in locks today. But with this simplicity comes a cost. As we will soon see, the spool pin is not as sneaky as it tries to be.

Are security PINs where lock picking goes to die?
This is the purpose of security pins, to take everything we as lock pickers have acquired—our knowledge, our experience, our techniques, and our developed sense of feel—and plot it against us. So is this the end? Are security pins where lock picking goes to die? Not even slightly. This is where our lock picking skills will flourish!
How do you release a locking pin?
Locking pins with ball lock or pawl To release the locking pin, simply press a release button at the tip of the connector. This allows the balls to move, and the pin can be pulled out.
How does a spring loaded locking pin work?
Locking pins are used for quick fixing, connecting and locking of various parts and workpieces. Pressing the spring-loaded push button unlocks both balls, and releasing it locks the balls again.
How do I install a spring loaded pin?
The simplest coiled pin installation method is to use a hammer. First, align the coiled pin up to the hole by hand. Next, simply hammer the coiled pin into the hole as if it was a nail. Drive the pin to the desired insertion depth and be careful not to damage the host.
What is a pin plunger?
Plungers are mechanical components for positioning and fixing workpieces. A spring is built into the main body so that the ball or pin at the tip sinks into the body when a load is applied, and is returned to its former position by spring force when the load is removed.
Who invented the pin tumbler lock?
The First Security Pin. In 1865, Linus Yale Jr. (inventor of the modern pin tumbler lock) took the first step in solving this problem by slicing a notch into the driver pins (Patent US48475). This simple modification would cause the driver pins to "catch" at the shear line if the plug was lifted under tension.
What is the most important component of lock picking?
The most vital component of lock picking is the torque —the rotational tension—that we apply to the lock's plug. Without this torque, we would not be able to bind the driver pins nor set and hold them at the shear line. To better understand this, let us briefly review how a pin is set on a simplified lock.
Why does my spool pin drop back into the plug?
The first is that because the spool pin causes the plug to counter-rotate, some pins that you had previously set could drop back into the plug. This is normal so don't fret if you have to re-pick pins you have already set. The second problem is that of over-setting a pin.
What happens when a security pin is falsely set?
1. The first of these two deceptions is that upon being falsely set, the gap in the security pin will break the bind and allow the plug to rotate until it once again finds the nearest pin to bind on (See Binding Order). This rotation is very similar to what we feel when a pin is correctly set at the shear line.
What is a spool pin?
Acquiring its name from its seen resemblance to a spool, the infamous spool pin has the same diameter as a standard pin on both its top and bottom segments, however , it has a wide horizontal serration making it narrower along its midsection.
What is lock picker feedback?
To we lock pickers feedback is absolutely everything. It is our sixth sense, our third eye, our perception within the lock that is beyond ordinary sight. The feedback we sense through our lock picking tools is what guides us and without it, we are but lonely souls probing the dark depths, looking for any signs of life—but forever finding none.
What happens if you get caught on a spool pin?
If you are indeed caught on a spool pin, the bottom ridge of the pin will slightly push back against the plug as you place pressure on the pin. You will feel an increase in pressure on your tension wrench as the plug slightly rotates in against it. This backward pressure on the plug is illustrated below.
