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 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 select the following operations by pressing the button of the remote
transmitter.
