Technology has made our life easier and that includes our automobiles as well. Along with the more efficient engines technology has helped us with the security of car also.

Like all modern tools that has spawned remote control gadgets to make our lives easier, the keyless entry remote was made to make it easy for us to open and close our car doors, open car trunks, roll down windows and activate our cars' alarm system from a distance with an easy push of a button in a single keypad. Really cool and convenient isn't it?

These modern car keys operate best within 5-20 meters or 15-60 ft. from our automobiles to make it work. While it depends on the car manufacturer, it is said that Ford uses a range of 20 meters for cars in their European and North American market and 5 meters for Japan and other markets to make up for greater restrictions in power transmission in their countries. The operational range is measured from the surface of the vehicle to a nominal central point. Corner pillars and small window openings reduces the signal of transmission so these factors will affect the operation of the keyless remote entry.

What ...
... happens when we push a button? A coded signal is sent by radio waves to a receiver unit in our vehicles, which automatically open or close its doors, open its trunks or activate its alarm system without physical contact. These radio frequencies vary for different countries. North-American vehicles operate at a frequency of 315 megahertz while European, Japanese and Asian cars use 433.92 megahertz. Worried, if you forgot to lock your doors? You can check by pushing on a button and a beep will emit from your car to signal if its doors are closed or not even if you are already far from your car but still within the operational range of the keypad. A single beep usually signifies the doors are close while a double beep means the doors are locked or whatever your keypad's code is.

Aside from acting like our invisible car attendant, these modern smart keys prevents car thefts because of an encryption in the key fob that prevents the engine from starting without the actual key itself which interacts with the broadcasted radio waves emitted from the car ignition and the chip in the keypad. Unless, the carnapper opts to push the vehicle to desperately own it, the car can't be driven away by unauthorized drivers!

Modern times calls for convenience in the use of almost all products, and car makers have made their product not only useful and sometimes a necessity by making it easy for vehicle owners to operate their cars through a single keypad that makes simple functions like opening and closing car doors, opening car trunks almost impossible when hands are tied up with carrying children or groceries. Not only that, through the same keypad you can prevent your car from being driven away by unscrupulous persons who are on the lookout for taking something that is not theirs. And you don't have to worry if you will lose your remote keys because you don't have to go to the car manufacturer to replace it, you can buy it from many sources online at a fraction of the original price.
