While the pin tumbler cylinder is by far the most popular door locking mechanism in the United States, it is not the only kind of keyed lock in common use. It is always best to practice with your lock mounted to a door or wood platform, as they are here, or at least fixed in a vice. Often raking is used to best effect in conjunction with pin-at-a-time picking. SFIC cylinders (such as those made by Best), used in large institutional lock systems, employ a similar mechanism to provide two kinds of keys: regular keys that operate the lock and control keys that unlock and remove the cylinder core itself. A common door lock mechanism in Europe uses a standardized "European profile" lock module. High security locks are more routinely installed in Europe than they are in the United States. Some lock manufacturers and locksmiths install special "security pins" intended to resist lock picking. The first sign of spool and mushroom pins is that the lock will appear to be picked, but will only turn a few degrees. You will also need a small re-pinning kit (available from locksmith suppliers as well as many home improvement and hardware stores) so you can easily add, remove, and re-arrange pins.

However, it is worth experimenting with different rakes and raking techniques to find one or two that work well for you. However, because they jam when false set, locks with serrated pins tend to impression very well (impressioning is a decoding technique that produces a working key based on marks left on a progressively cut key blank). You may well have one of these locks on your house. If only serrated top pins are used, reverse picking may be successful. If serrated bottom pins are used as well (as they are in, e.g., certain American brand padlocks), snap guns, bump keys, or sawtooth raking are likely the only picking techniques that will succeed, especially for the novice. The pin stacks with regular pins will feel just as you'd expect, with a hard stop when the bottom pin hits the shear line. Pin stacks with partially set spool and mushrooms, on the other hand, will feel a bit different. And now see how you feel. See Figure 7 for an example of a serrated pin. See Figure 6 for an example of a spool pin. Figure 6. Abus "spool" top pin. While applying light to moderate torque, push and pull a gently rounded rake pick from front to back and back to front along the pin stacks.

Actually, the word "om" is spelled out in Sanskrit a-u-m, and thus comprises the whole range of sound from the back of the throat to the lips. A crazy person might get by accident into some of these states, and get so lost that he wouldn’t know how to come back to the world of ordinary normal conventions. If they were, they wouldn’t be involved in this mess. If I were to identify myself with "Alan Watts," that would be identifying myself with a concept, with words-a rather complicated mess of words, to be sure, but still I would have made that mistake. The design is based on the late 18th century British Bramah lock (still in production and use today). You may find one of the smaller LAB hook picks to be easier here than the larger Peterson picks, although you can usually still pick this keyway with the small Peterson hook. Again, try to find and lift all the pins with the different hook picks without applying any torque. Become comfortable with this before you try picking this lock with torque or you could bend or break your picks.

When you've mastered the SX locks, try the "Schlage SC" keyway locks. Schlage SC is a very common keyway. The large board has locks with eight different keyways, representing many of the most common keyway designs used in the US. Tubular cylinders typically have four to eight pin tumblers arranged in a circular pattern around the circumference of the plug. Most pin tumbler cylinders can be "master keyed" to allow more than one key bitting to operate it. If you can pick all (or at least most) of the locks on this board, you are well prepared against the typical locks installed in residential and commercial buildings in the US. The Peterson "Reach" deep curve pick works well for this keyway, pivoting from the bottom of the keyway at the front. Snap guns are occasionally successful as well. If just one pin sets at the "other" shear line, the lock will not open even though all the pin stacks are picked. The most comprehensive treatment of raking techniques I've found is in the Finch Manual of Lock Picking, although other authors have different perspectives on the subject.
