Spool pins are designed to ensure that the plug cannot rotate unless there is an exact key cut in its keyway while turning.
The spool pin will be one of the first stops when lock picking. Spool pins are designed to ensure that the plug cannot rotate unless there is an exact key cut in its keyway while turning it. The spool pins on this lock will have some sort of U-shape notch on them, often times these do not look like a full notch but more like an indentation or indented ring around the shaft of the pin.
These spool pins are also designed to bind up if they detect foreign items down inside their cylinders and make life very difficult for any would-be lock pickers trying to get past them. The best way to deal with these types of pins is simply by using your picks to bump each pin until they are set.
This is a tedious process, but it's much easier than picking the lock open without these spool pins.
Bump keys are also a way that can be used to deal with spool pins, but they risk damaging the pins and drastically shortening the life of any lock. For this reason, it is important to use your bump key properly.
The general rule for bumping is to never let the key fall too far down into the lock as you are picking it up and out of each pin's keyway. This is just one task of a professional locksmith. You do not want to drop the key all the way down to where spool pins are located because you will damage them and create additional problems.The purpose of spool pins is to provide feedback when key bits are inserted in the lock. This helps ensure that the correct key is used and also prevents someone from inserting random foreign objects (paperclips, shims) in an attempt to bypass the lock.
A common use for spool pins is on vehicles with remote keyless entry systems. The car or truck can detect if a valid ignition key is being turned in its lock cylinder by monitoring whether appropriate spool pins are pushed back as the ignition switch rotates. If there's no activity, then it will assume that either its battery has gone dead or something else has happened to prevent the user from starting their vehicle.
Spool pins can be found in many locksmithing applications, but are most commonly seen in precision locksmithing applications such as automobiles and high-security locks.Spool pins are typically made of an alloy that is non-magnetic, some examples would be brass, titanium, nickel/silver alloys.
Spool pins can take many shapes, but they typically look like a spring or bobby pin that has been bent into an "S" shape. The tips of the spool pins will often be deformed and misshapen to prevent them from rotating freely in the keyway, and they also often have a notch cut into them so they know when their "home" position is. This notch allows the lock to automatically retract these spool pins whenever it detects its proper key inserted which helps keep dust and debris out.
Check the diameter of the pins to note and post an important sign. Make sure to refer a professional in order for a lock to be pulled. And you need to keep in mind not to use force when you install or slide a vertical spool pin or horizontal spool pin into a lock or adapter.
To pick these pins correctly you need to hold them in place with tension while slowly lifting each one up individually using your picks. Once the first few are lifted high enough, then your last pin which is binding should clear its home position and allow itself to be pushed back down by spring tension. This same process can also be done with an auto-lock extractor.
Many spool pins can be replaced, but it depends on the design and manufacturer of the lock and spool pin. Some locks use a dowel or small screw that holds them in place while others can be simply pried out with some basic tools. Spool pins that are integrated into your lock's manufacturing will more than likely not be replaceable as they are almost always press-fit to the lock. However, you should always check with your lock manufacturer prior to performing any repairs as they may void warranty coverage if certain steps aren't followed for replacement options.
Spool pins can vary in many ways. They can be made from different materials and shapes, but the main difference is a matter of quality. Many cheaper locks use stamped spool pins out of sheet metal that is not smooth and has burrs that will wear down quickly when used. Some spool pins have a felt and catch with some tricks to help you not to forget the distance and process. These types of spool pins also have a much shorter lifespan than their all-brass or titanium counterparts due to being made from inferior metals under poor manufacturing processes. It is always advisable to check with your lock manufacturer before making any repairs if possible so you can verify proper installation procedures for replacement spool pins intended for that lock type.
A lockpick is often used to push the driver pins out of the way while wiggling it slightly back and forth which will cause the key pins to bind within its shear line without fully retracting into the lock's casing. When this happens, then that energy creates enough torque on all pin stacks to allow for rotation which will activate the internal core components allowing you to unlock your lock.
Bump keys are specifically designed key blanks intended for locksmiths to use when they want their customers' original keys duplicated quickly, easily and cheaply. These special key blanks have several raised bumps on their blades that will bump each pin stack to its sheer line without applying too much torque or weight which would cause the pins to bind. This makes lock bumping one of the quickest and easiest ways for a locksmith to open most locks if needed.
Shimming is when you use something thin, flat and rigid to press against either side of your lock's driver pins usually with some light tension applied so it doesn't fall out of place after you put all your energy into opening your lock. This process can be done by hand if you have enough time, but it's typically easier with some picks inserted in the keyway just above the keypins as a brace while inserting a thin metal shim below the keypins to press them up. This will work similarly to holding a ball on top of a hill and pushing it down with your finger while using another finger on the left side of the ball to hold it in place while you slightly raise your first finger that's pushing down on it.
Yes, but they're usually designed differently than homemade ones and some even have very unique and patented designs that can also be used for illegal purposes if they fall into the wrong hands.
Most professional locksmiths know how to make their own lock picks from basic materials including metal or plastic rods which are often modified with things like files or sandpaper depending on their intended purpose.

They do this by grinding down one end of a metal or plastic rod into a shape that fits into their lock's keyway then shaping the other end into a precise tension wrench that they can apply slight pressure with while using another pick to manipulate pins within their shear line.
