While a fairly wide range of torque will sometimes pick these locks, try find the lightest torque that works. However, it is worth experimenting with different rakes and raking techniques to find one or two that work well for you. When the energy transfers, the top pin moves up while the bottom pin slows down, and a gap is created between the two pins. An alternative technique, which I have not seen mentioned in the literature, is to first determine which pin stacks have security pins and which have regular pins (by picking normally and noting which stacks are false set). The Y1 keyway is one of the toughest you are likely to encounter in real lock installations in the US. Finally, for a real challenge, try the Yale "Y1" keyway locks. Very "wavy" rake picks can simulate various key profiles, and can be surprisingly successful at opening poorly-made locks. A variety of schemes are used to key the sidebar.


The pockets in the middle of the long rails are called side pockets. Note how the wards extend across the front of the pins; this is called a "paracentric" design in locksmithing parlance. 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. When the final (non-security) pin is set, the lock should open. As you progress, you should know the state of the lock at all times: which pins are set, which aren't, which one is binding. Once you've picked a cylinder, you should know in exactly what order the pins pick. While pins are usually set by raising the cut from the plug to the shear line, they can also be picked by first oversetting the cut to within the shell and then lowering it to the shear line. Note that other pins may unset at this point, and may have to be picked again. Now release torque and start over, taking care to pick all the pin stacks with spool/mushroom pins while leaving at least one regular pin stack unset (this will require a light touch and good sensitivity).


You'll probably want to use one of the smaller LAB picks, although the small Peterson hook will sometimes do with care and practice. You may want to use one of the smaller torque tools as well, or put your torque tool in the bottom part of the keyway instead of the (curvy) top. Major Tobias Clutterbuck, and put his arm for the second time around his companion. One might put up a little hurdle-nothing obtrusive-only a matter of a few inches high. And actually, you can’t divide up the land, because in Sausalito, where I live (which is on the harbor of San Francisco), they’ve recently been dredging out the silt to build a marina, and they thought, "Well, we have a perfect right to do this because it’s on our land." But all the land owners on the shore are suddenly discovering that earth is really fluid, and it’s beginning slowly to fill in the dredged-out part so that everybody’s shoreland is getting under water at high tide. Understanding the theory of lock picking is only a small part of being able to successfully pick locks. Eventually, you'll be able to comfortably pick the locks with five and six pins installed.


Pool involves a table with six pockets. The billiard table consists of a flat playing surface with six pockets. Straight Pool, also known as 14.1 Continuous, is a classic game where players aim to reach a certain point total by potting any ball on the table. Now apply heavy torque, with the aim of pinching all the bottom pins at the shear line. If the shear line is within this gap as torque is applied, it may set. 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. It will take a bit of practice to find just the right technique. Again, try to find and lift all the pins with the different hook picks without applying any torque. To pick this keyway, you'll need a small hook pick and a bit of twisting as you lift. The Peterson "Reach" deep curve pick works well for this keyway, pivoting from the bottom of the keyway at the front.
