A physical key similar to say to a doorknob or something; are they molded? Carved to be capable of porportionally fit a lock and open a door?
Or is a lock made to fit a switch? How?

Lock-picking is an means possessed primarily by locksmiths and by persons involved surrounded by intelligence or detective work for which secrecy is a necessity. Requiring a large degree of reasoning power and power-driven dexterity, lock-picking even has its amateur enthusiasts who simply wallow in the challenge. The tools of the trade can involve an amazing array of devices, but most are variation on a simple pick mechanism that a skilled and long-suffering practitioner can replicate even with a newspaper clip.
Basic technique. One of the simplest types of lock to pick is known as a pin-and-tumbler design. This lock uses a row of pins, divided into pairs, which rest contained by a row of shafts running perpendicular to the lock's major cylinder plug and its housing mechanism. Insertion of the right knob forces the top and bottom pins apart at just the right distance so that adjectives of the upper pins rest in the outer housing and adjectives of the lower pins rest in the plug. At that point, no pins bind the plug to the housing, aim that the cylinder can be turned freely, releasing the bolt that holds the locking mechanism surrounded by place.
To open such a lock short a key, one desires a long, thin piece of metal next to a curved end (a pick), which can be inserted favourably inside the lock as one would a key. Moving beside finesse, it is possible to adjust all the pins into place so that the cylinder can be turned as though the push button had be used. Or one can apply a sloppier variation, particular as raking, within which a pick is inserted and pulled out quickly while the cylinder is turned near a tension wrench such as a flathead screwdriver.
Tools. Experienced lock-pickers use a yawning array of tools. They are likely to stir to work using an entire tool kit next to picks, "rakes" (picks for raking a lock), and stiffness wrenches, all of which are small satisfactory that a basic lock-picking utensils could fit into a pocket. To be equipped for a greater range of eventualities, a lock-picker may use a tackle that includes other tools, such as a burglar alarm evasion kit, a key-impression tackle (for making a key base on impressions that a lock makes on a knob blank), a key-pattern device (for copying old-fashioned warded key, made to fit into lever locks), files, and other items.
Even more sophisticated is an electric lock-opening device, which is used in tandem beside a pick to move the pins into the proper position. Additionally, a lockpick gun can be used to open most pin-tumbler mechanism. By squeezing the trigger, one strikes the pins with the pick, after which a rigidity wrench is applied to turn the lock cylinder.
There are other varieties of technique and tools, just as in attendance are variations within lock design, such as the wafer-tumbler lock, in which tumblers contained by the shape of wafers take the place of pins. Most aspects of lock-picking are simple surrounded by concept, but far from easy surrounded by application. Good locksmiths are almost always perfect lock-pickers, and the reverse is almost as true: a talented lock-picker, for instance, should know how to reconfigure a lock to fit a particular push button, a skill that would obviously be of gargantuan advantage to an intelligence officer within a covert operation.
Answers: Keys are made from "blanks" or pieces of metal and cut to a size with ridges that poke up at assorted intervals. IE: For the standard five-tumbler key lock, the knob is made first. The lock manufacturer buys push button blanks and cuts the ridges, or combinations, in respectively key. Each switch has five bumps on it that are cut to different level. These levels are designated by numbers. A low cut is one, subsequent up is two, then three. In several cases, there are single four levels, though some manufacturer may use as many as seven. A five-tumbler switch lock with four level in the switch yields four to the fifth power, or 1024, different possible combinations of ridges contained by the key. The five ridges are nominated by the height of respectively level, ductile what is called the combination for the switch. A key beside the combination 12341 is cut with the first ridge at height one, the second at two, the next at three, and so on. The lock businessman chooses the combinations from a random register and cuts each switch differently.
