You can also set pins on top of one another so that multiple keys can successfully turn the cylinder, using a '''"master"''' key and a '''"change"''' key. The idea is that several cylinders will be keyed to the "master" and each cylinder will also be keyed to its own unique "change" key.

Locks

There are many different kinds of locks. Most of the locks that you'll play with on a day-to-day basis are pin tumbler locks, primarily of two brand names:

  • Schlage (slightly sturdier, more versatile)
  • Kwikset (slightly less sturdy, made of sand)

The inside of a typical pin tumbler lock, animation shows how the pins are set to enable the cylinder to turn and release the latch/deadbolt:

You can also set pins on top of one another so that multiple keys can successfully turn the cylinder, using a "master" key and a "change" key. The idea is that several cylinders will be keyed to the "master" and each cylinder will also be keyed to its own unique "change" key.

Law

  • In California, it is lawful to duplicate existent keys. Further, a "Locksmith" is defined as a person who engages "in the business of rekeying..." etc, "for any consideration or compensation whatsoever" ('consideration' meaning benefit of a contract i.e. not a gift).
(j) "Locksmith" means any person who, for any consideration or
compensation whatsoever, engages, directly or indirectly and as a
primary or secondary object, in the business of rekeying, installing,
repairing, opening, modifying locks, or who originates keys for
locks, including, but not limited to, electronic cloning of
transponder keys and any other electronic programming of automotive
keys and electronic operating devices, such as key fobs, door and
ignition key devices, and successive electronic and other
high-security key technology. A "locksmith" does not mean a person
whose activities are limited to making a duplicate key from an
existing key.
