The major advantage of keyless remote programming is the convenience of using the keyless remotes. The remote device allows for locking and unlocking the door, activating the alarm and in some cases starting the engine just at the press of a button.
Keyless remote programming helps warm up the car remotely on a cold day by starting the engine without having to enter the vehicle. Another advantage of programming a keyless remote is that it can be incorporated into the security system of a house or building, a garage door opening mechanism or a unit to remotely switch on the lights within a building. It allows locking and unlocking the doors, releasing the trunk or tailgate and setting the alarm from a distance.
The programming can also include having a button that triggers a panic alarm. Another safety feature that a remote keyless entry offers is an LED light flashing within the vehicle, indicating the vehicle is ready. It can trick a potential thief. Hence, apart from the convenience, the keyless remote programming also addresses security.
The computer programming for the keyless remotes is rather simple. It uses a unique, digitized identification code that identifies the vehicles within the broadcast range. The procedure for programming associates a specific vehicle with a key fob.
