To meet the specific needs of modern customers, automakers are introducing the cars with high-tech features, better performance, and added goodies. From heightened traction control to theft deterrent devices, and front and side airbags to Onstar safety and security network, a number of features have been added to modern vehicles, providing the drivers the unique riding experience. In the list of these innovative features, keyless remote entry is also the one, gaining huge popularity among modern riders.

Keyless remote technology was developed in automobile sector, to permit or deny the access to a vehicle without any use of key. Initially, it was like a key-pad where a pre-determined numeric code was entered to access the vehicle, without manual key operation. That is why the phrase- Keyless Remote Entry means the 'entry without use of key'. In this technology, a device (typically in the form of key-fob or electromechanical key) is used to remotely control the various functions of a vehicle such as locking/unlocking the doors, releasing car trunks, and switching on/off the ignition and interior lights. Furthermore, the device provides a code-protected secure mechanism to the vehicle too.

The remote device is equipped with some panic buttons, which allow the riders to perform numerous basic functions of the car. Apart from this convenience, the rider can use the feature as a self defensive crime prevention technique, to summon help, or to startle an attacker through district alarm sound. This can also help the rider to find the car location in a busy parking lot. Since the latest technology uses cyclic cryptographic code that changes automatically after every transmission, it prevents the vehicle from grabbing or scanning attacks. Thus, the technology enhances the riding experience in terms of both convenience and safety.

Functionality of this technically strong feature depends upon the wave based communication between a small circuit chip and an RF receiver. The chip is kept inside the key-fob, where the electronic RF receiver is installed in the vehicle. Pressing the button on key-fob, the chip emits radio waves on a fixed frequency. Most of the devices perform on 315 MHz (in the United states and Japan), and 434/868 MHz (in Europe) RF bands. Now, the RF receiver catches the code and identifies it. If the transmitted code is correct, the electronic RF receiver allows to operate the requested task.

As stated earlier, the device performs at a fixed radio frequency. If it doesn't work from a normal distance, there may be two reasons – first one is the weak batteries in remote transmitter, and the another one is the proximity to a strong radio transmitter such as radio station or airport transmitter. In case when you have lost the remote key, the problem could be solved by some reputed locksmiths, who specialize in selling the key hardware and reprogramming them in vehicles. What you need to do is to search for a reliable one in/around your area, and order for the smart key for your car model.
