By Wikipedia:
A key is a device which is used
to open a lock. A typical key
consist of two parts: the blade,
which slides into the keyway of
the lock and distinguishes
between different keys, and the
bow, which is left protruding so
that torque can be applied by
the user. The blade is usually
designed to open one specific
lock, although master keys are
designed to open sets of similar
locks.
Keys provide an inexpensive,
though imperfect, method of
authentication for access to
properties like buildings and
vehicles. As such, keys are an
essential feature of modern
living in the developed world,
and are common around the globe.
It is common for people to carry
the set of keys they need for
their daily activities around
with them, often linked by a
keyring adorned by key fobs and
known as a keychain.
Special types of keys
House keys
A house key is the most common
sort of key. There are two main
forms. The older form is for
lever locks, where a pack of
flat levers (typically between
two and five) are raised to
different heights by the key
whereupon the slots or gates of
the levers line up and permit a
bolt to move back and forth,
opening or closing the lock. The
teeth or bittings of the key
have flat tops rather than being
pointed. Lever lock keys tend to
be bigger and less convenient
for carrying, although lever
locks tend to be more secure.
These are still common in, for
example, many European
countries.
The more recent form is that for
a pin tumbler cylinder lock.
When held upright as if to open
a door, a series of grooves on
either side of the key (the
key's profile) limits the type
of lock cylinder the key can
slide into. As the key slides
into the lock, a series of
pointed teeth and notches allow
pins to move up and down until
those pins are in line with the
shear line of the cylinder,
allowing that cylinder to rotate
freely inside the lock and the
lock to open. These predominate
in, for example, the United
States of America.
Car key
Main article: Power door locks
Ignition switch between the
seats (2005 Saab 9-5).
Car keys .A car key or an
automobile key is a key used to
open and/or start an automobile,
often identified with the logo
of the car company at the head.
Modern key designs are usually
symmetrical, and some use
grooves on both sides, rather
than a cut edge, to actuate the
lock. It has multiple uses for
the automobile with which it was
sold. A car key can open the
doors, as well as start the
ignition, open the glove
compartment and also open the
trunk (boot) of the car. Some
cars come with an additional key
known as a valet key that starts
the ignition and opens the
drivers side door but prevents
the valet from gaining access to
valuables that are located in
the trunk or the glove box. Some
valet keys, particularly those
to high-performance vehicles, go
so far as to restrict the
engine's power output to prevent
joyriding. Recently, features
such as coded immobilizers have
been implemented in newer
vehicles. More sophisticated
systems make ignition dependent
on electronic devices, rather
than the mechanical key switch.
Ignition switches/locks are
combined with security locking
of the steering column (in many
modern vehicles) or the gear
lever (Saab Automobile). In the
latter, the switch is between
the seats, preventing damage to
the driver's knee in the event
of a collision.
Keyless entry systems, which
utilize a remote control in
place of a car key, are becoming
a standard feature on many new
cars. Some of them are hands
free.
Switchblade key from a 2005 Land
Rover LR3.Some keys are
high-tech in order to prevent
the theft of a car.
Mercedes-Benz uses a key that,
rather than have a cut metal
piece to start the car, uses an
encoded infrared beam that
communicates with the car's
computer. If the codes match,
the car can be started. These
keys can be expensive to
replace, if lost, and can cost
up to US$400. Some car
manufacturers like Land Rover
and Volkswagen use a
'switchblade' key where the key
is spring-loaded out of the fob
when a button is pressed. This
eliminates the need for a
separate key fob. This type of
key has also been known to be
confiscated by airport security
officials.
Master key
A master key is intended to open
a set of several locks. Usually,
there is nothing special about
the key itself, but rather the
locks into which it will fit.
These locks also have keys which
are specific to each one (the
change key) and cannot open any
of the others in the set. Locks
which have master keys have a
second set of the mechanism used
to open them which is identical
to all of the others in the set
of locks. For example, master
keyed pin tumbler locks will
have two shear points at each
pin position, one for the change
key and one for the master key.
A far more secure (and more
expensive) system has two
cylinders in each lock, one for
the change key and one for the
master key.
Larger organizations, with more
complex "grandmaster key"
systems, may have several master
key systems where the top level
grandmaster key works in all of
the locks in the system.
A practical attack exists to
create a working master key for
an entire system given only
access to a single master-keyed
lock and its associated key.
This is described in Cryptology
and Physical Security: Rights
Amplification in Master-Keyed
Mechanical Locks
Locksmiths may also determine
cuts for a replacement master
key, when given several
different key examples from a
given system.
Control key
A control key is a key used in
interchangeable core locking
systems. The control key enables
the user to remove a core in the
cylinder, with a specific
combination and replace it with
a core with a different
combination. In small format
interchangeable cores, similar
to those developed by Frank Best
of the Best Lock Corporation,
the key operates a separate
shear line, located above the
operating key shear line. In
other format interchangeable
cores, the key may work like a
master key along the operating
shear line and also contact a
separate locking pin that holds
the core in the cylinder.
Double-sided key
A double-sided key is very
similar to a house or car key
with the exception that it has
two sets of teeth, an upper
level standard set of teeth and
a lower, less defined set of
teeth beside it. This makes the
double-sided key's profile and
its corresponding lock look very
similar to a standard key while
making the attempt to pick the
lock more difficult.
Para centric key
A Para centric key is designed
to open a Para centric lock. It
is distinguishable by the
contorted shape of its blade,
which protrudes past the centre
vertical line of the key barrel.
Instead of the the wards on the
outer face of the lock simply
protruding into the shape of the
key along the spine, the wards
protrude into the shape of the
key along the entire width of
the key, including along the
length of the teeth.[2] Patented
by the Yale lock company in
1898, paracentric cylinders are
not exceptionally difficult to
pick, but require some skill and
know-how on the part of the
person attempting to pick the
lock.
Skeleton key
A warded lock fits both its key
and skeleton keys its size or
smaller.
A bronze skeleton key A skeleton
key (or passkey) is a very
simple design of key which
usually has a cylindrical shaft
(sometimes called a shank) and a
single, minimal flat,
rectangular tooth or bit.
Skeleton keys are also usually
distinguished by their bow, or
the part one would grasp when
inserting the key, which can be
either very plain or extremely
ornate. A skeleton key is
designed to circumvent the wards
in warded locks. Warded locks
and their keys provide minimal
security and only a slight
deterrent as any key with a
shaft and tooth that has the
same or smaller dimensions will
open the lock. However, warded
keys were designed to only fit a
matching lock and the skeleton
key would often fit many. Many
other objects which can fit into
the lock may also be able to
open it. Due to its limited
usefulness, this type of lock
fell out of use after more
complicated types became easier
to manufacture. In modern usage,
the term "skeleton key" is often
misapplied to ordinary bit keys
and barrel keys, rather than the
correct definition: a key,
usually with minimal features,
which can open all or most of a
type of badly designed lock. Bit
keys and barrel keys can be
newly-minted (and sold by
restoration hardware companies)
or antiques. They were most
popular in the late 1800s,
although they continued to be
used well into the 20th century
and can still be found today in
use, albeit in vintage homes and
antique furniture. A bit key is
distinguished from a barrel key
in that a bit key usually has a
solid shank, whereas a barrel
shafted key can be made either
by drilling out the shank from
the bit end or by folding metal
into a barrel shape when forging
the key.
Tubular key
A tubular key A tubular key
(sometimes referred to as a
barrel key when describing a
vintage or antique model) is one
that is designed to open a
tubular pin tumbler lock. It has
a hollow, cylindrical shaft
which is usually much shorter
and has a larger diameter than
most conventional keys. Antique
or vintage-style barrel keys
often closely resemble the more
traditional skeleton key but are
a more recent innovation in key
making. In modern keys of this
type, a number of grooves of
varying length are built into
the outer surface at the end of
the shaft. These grooves are
parallel to the shaft and allow
the pins in the lock to slide to
the end of the groove. A small
tab on the outer surface of the
shaft prevents the pins in the
lock from pushing the key out
and works with the hollow center
to guide the key as it is
turned.
The modern version of this type
of key is harder to duplicate as
it is less common and requires a
different machine from regular
keys. These keys are most often
seen in home alarm systems, in
the United States.
Zeiss Key
A Zeiss key (also known as a
Cruciform Key) is a cross
between a house key and a
tubular key. It has three sets
of teeth at 90 degrees to each
other with a flattened fourth
side. Though this type of key is
easy to duplicate, the extra
sets of teeth deter lockpicking
attempts.
Do Not Duplicate Key
A keychain, a simple way to hold
keys A Do Not Duplicate key (or
DND key, for short) is one which
has been stamped do not
duplicate , duplication
prohibited or similar by a
locksmith or manufacturer as a
passive deterrent to prevent a
retail key cutting service from
duplicating a key without
authorization or without
contacting the locksmith or
manufacturer who originally cut
the key. More importantly, this
is a control system for whoever
is the owner of the key, such as
a maintenance person or security
guard, to identify keys that
should not be freely distributed
or used without authorization.
Though it is intended to prevent
unauthorized key duplication,
copying restricted keys remains
a common security problem. There
is no direct legal implication
in the US for someone who copies
a key that is stamped do not
duplicate (unless it is a
government owned key), but there
are patent restrictions on some
key designs (see "restricted
keys"). The Associated
Locksmiths of America calls DND
keys "not effective security",
and "deceptive because it
provides a false sense of
security."
United States Code 18 USC Sec.
1704 deals with United States
Post Office keys, and 18 USC
Sec. 1386 deals with United
States Department of Defense
keys.
Restricted Key
A restricted key blank is a
keyway and blank for which a
manufacturer has set up a
restricted level of sales and
distribution. Restricted keys
are often protected by patent,
which prohibits other
manufacturers from making
unauthorized productions of the
key blank. In many
jurisdictions, customers must
provide proof of ID before a
locksmith will duplicate a key
using a restricted blank. These
days, many restricted keys have
special in-laid features, such
as magnets, different types of
metal, or even small computer
chips to prevent duplication.
Keycard
A keycard, while not actually
considered a key, is a plastic
card which stores a digital
signature that is used with
electronic access control locks.
It is normally a flat,
rectangular piece of plastic and
may also serve as an ID card.
There are several popular type
of keycards in use and include
the mechanical holecard, bar
code, magnetic stripe, smart
card (embedded with a read/write
electronic microchip), and RFID
proximity cards. The keycard is
used by presenting it to a card
reader; swiping or inserting of
mag stripe cards, or in the case
of RFID cards, merely being
brought into close proximity to
a sensor.
Bar code technology is not a
secure form of a key, as the bar
code can be copied in a
photocopier and often read by
the optical reader.
Magnetic stripe keycards are
becoming increasingly easy to
copy, but have the security
advantage that one may change
the stored key in a magnetic
swipe card in case the current
key may be compromised. This
immediate change of the "key"
information can be applied to
other media, but this media
probably offers the least
expensive option, and the most
convenient to users and managers
of systems that use this media.
Example: If you own a car with
this system, you can change your
keys anytime you want. You can
buy new media anywhere a gift
card is sold. At least at this
point in time, you could buy a
gift card for a penny, then use
that as the media for the keys
to your car. If the system uses
digital environmental data
samples to create the "key"
string, every car can have a set
of keys that no one else has. If
a card is stolen, or copied
without authorization, the card
can be remade, and the car
security system can be
synchronized with the new card,
and no longer activation ally
responsive to the copy of the
old card. This approach can
empower the system controller
(owner/individual or centralized
administration of a business).
Computerized authentication
systems, such as key cards,
raise privacy concerns, since
they enable computer
surveillance of each entry.
Currently RFID cards and key
fobs are becoming more and more
popular due to its ease of use.
Many modern households have
installed digital locks that
make use of key cards, in
combination with biometric
fingerprint and keypad PIN
options.
The first keycard was the
mechanical hole card type
patented by Tor Sørnes, a
concept he later developed into
the magnetic stripe card key.
