Keyless Entry System for Cars

As the technology implemented in cars is evolving day by day, many convenient and luxurious features are being included as standard options. One such beneficial feature found in automobiles manufactured today is the keyless entry system. This luxury system is far more developed now than it was several years ago.

As the name portrays, this is a technology that allows the driver to get into the car without a key. It was first used in the 1980s, with the setup comprising a keypad located at the door's handle. The driver had to simply key-in a preprogrammed access code for the doors to be unlocked. This system was generally used by General Motors car models such as Buick Regal and Oldsmobile Cutlass Supreme. However, nowadays, these are used widely as a standard luxury car feature.

Remote Keyless Entry System for Cars
Typically, a setup of remote keyless access can consist of a Remote Keyless Entry (RKE) as well as a Remote Keyless Ignition (RKI) system. RKE pertains to locking or unlocking car doors remotely, without using an actual key. It can even relate to starting the engine remotely without getting into the car and turning on the ignition with the metal key, which is known as remote keyless ignition. These systems might consist of just an electronic key fob, or the conventional metal key with an electronic key handle.

The functioning of remote keyless entry systems is carried out with the help of radio waves at certain frequency. In these systems, the frequency range in North America is 315 MHz, whereas that in Europe is 433.92 MHz. There are buttons on the key fob or key handle; such as for locking and unlocking doors, opening the trunk or tailgate, operating windows and roof, activating or deactivating car alarm, and even starting the ignition remotely. When you operate the remote keyless system; the car will either indicate about the action using specific sounds, flashing all indicators at once, or other indications.

The range of operation varies from manufacture to manufacturer. For example, Ford normally sets a range of 20 m for Europe and North America, whereas 5 m for countries restricting transmitted power. The latest in this technology is known as the 'Advanced Key' system. In this system, there is no need for the driver to press buttons on the key fob or electronic key handle for operating the doors or ignition. Instead, the system in the car automatically senses if the electronic key carried by the driver is approaching, and the appropriate action is performed.
