1. Constitution of the Radio Frequency Keyless Entry System for vehicle
The radio frequency keyless entry is a system that it controllers 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.
OPERATION ACTION
LOCK lock the door
UNLOCK unlock the door
PANIC alarm the siren

5. Features
5.1 Door lock control
The LOCK relay in the receiver drives the door lock actuators to "LOCK"-side when LOCK button of
transmitter was pressed. The UNLOCK relay in the receiver drives the door lock actuators to
“UNLOCK”-side when UNLOCK button of transmitter was pressed. These facility doesn't work if the
key is inserted the key cylinder or the door is open.
5.2 Battery saving
Because of the power source of the receiver is car Battery, it is very important problem to minimize
power consumption. The receiver's CPU works intermittently to prevent the battery exhaustion.
6. Derivatives
