Pretty
much all new cars nowadays are equipped with smart key technology, which has
made putting a key into your car's door to unlock it or into the ignition switch
to start your car's engine obsolete. Now you have a transmitter fob, which
relies on radio frequencies to unlock a car's doors and start its engine. At the
beginning, when intelligent car keys were first introduced, they were mostly
used in luxury cars, since it was an expensive technology, and it didn't make
sense to implement it in less expensive cars. Some of the most popular and
advanced smart key systems include Mercedes-Benz's Keyless Go integrated into
SmartKeys, Toyota's Smart Key System, Lincoln's Intelligent Access System, and
BMW's Comfort Access.
Vehicles that come with such technology are
equipped with computerized systems, and can identify the driver as they are
approaching the car. The system uses several microchips and sensors that
transmit information to the smart key, which opens the car's doors thanks to a
radio transponder chip that is installed in the key. This is a so called Passive
Keyless Entry System, which doesn't even require you to take your key out of
your pocket or your bag and pushing a button to unlock the doors. Once you've
entered your car, you can start the engine by pressing the engine start
button.
These are perhaps the most significant advantages of intelligent
over traditional car keys. In addition to being very convenient, they make your
car difficult to steal. This is because thieves can't unlock and start a car
that has smart key features using the traditional method, that involves cutting
some wires, then stripping and connecting them. The computer system in the car
requires that the correct code|code calculatordecoder|free
codes|decoderdecoding|sstandards|regulations|unlock} from the smart key is
transmitted, and if it doesn't receive it, it won't get the car going, no matter
which and how many wires are cut and connected.
As far as the downsides
are concerned, it's worth noting that there are some added costs that come with
owning a car with a smart key technology. If you happen to lose your smart key,
it may cost you over $100 to replace it, whereas replacing a traditional key
only costs $10 - $15. Plus, you can't buy a new intelligent key wherever you
want, since it's a technology that is trademarked by your car's manufacturer,
and you can only get one at an authorized dealership, which means you'll
probably waste a lot of time and go through quite a hassle while trying to find
a replacement key.
Furthermore, if you forget to turn off the engine
before you leave the car, and leave the car in your garage, carbon monoxide will
be released and it will get inside your house, which can result in fatal
consequences.
