1. Constitution of the Radio Frequency Keyless Entry System for vehicle
The radio frequency keyless entry is a system that it controls locking and unlocking the door and the trunk by
wireless remote controller. This system consists of three components. The TRANSMITTER is a device that
transmits the signal when the button is pressed. The transmission signal consists of several synchronous
codes , unique identification code , security code and function code. The RECEIVER is fixed inside the vehicle.
It works intermittently to prevent the battery exhaustion. When the receiver detects the synchronous code, it
runs continuously to receive the signals completely. After receiving the signal, the receiver decides which
operation will be performed. The user can selectthe following operations by pressing the button of the remote
transmitter.
