1. Constitution of the Radio Frequency Keyless Entry
System with Door Lock Controller for vehicle
The radio frequency keyless entry is a system that it controlls locking and unlocking the door by
wireless remote controller. This system consists of two 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 receiveing 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 and output the signal to security unit
UNLOCK Unlock the door and output the signal to security unit
BOOT RELEASE Release the boot
PANIC Beep the horn and flush the small light. (it continues 30 seconds)
This receiver also controls wired operation. When the key is in the driver’s side key cylinder, all doors will
Unlock if the key is turned to UNLOCK and hold more than one second. In case of the operation time is shorter,
the only diver’s side door is mechanically unlocked. It is also available to control the door lock status by using
the remote door control switch(both driver’s and passenger’s side).

2. User’s manual (provisionally)
LOCK
When you push the LOCK button, all the doors will lock. And output the signal to security unit.
You cannot lock any of the doors with the remote transmitter if any door is open or the key is in the
ignition switch.
UNLOCK
When you push the UNLOCK button once, all the door s will unlock. And output the signal to security
unit.
You cannot unlock any of the doors with the remote transmitter if the key is in the ignition switch.
BOOT RELEASE
To open the boot, push the BOOT RELEASE button for approximately 0.5 second.
The boot will not open if the key is in the ignition switch.
PANIC MODE
Panic mode allows you to remotely sound your vehicle’s horn to attract attention. To activate this mode,
press and hold the PANC button for about one second. Your vehicle’s horn will beep for about 30 seconds.
To cancel panic mode before 30 seconds, press any button on the remote transmitter. You can also turn
the ignition switch to ON.
Panic mode will not activate if the ignition switch is in ON.

5. Features
5.1 Integrated controller
The controller works both wireless and wired operation.
You can use it remotely as the receiver of the keyless entry system. You can operate the door lock
remotery using the remote transmitter. It is also avialable to release the boot.
When you turn the door lock switch, the controller works as the door lock controller. The controller
monitors the switch related to the door lock. In case of the status of the switch changed, the controller will
detect and output the signal to the door lock actuator.

5.2 Battery saving
The receiver works intermittently to reduce the battery consumption. The microcomupter mounted on
the receiver controlls the power supply for the RF circuit. In case of the microcomputer detects the wake-up
signal during the power supplied, the microcomputer continue supplying the power until the data frame will
be received.
