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
UNLOCK Unlock the door （Open the window）
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).

f = 313.85MHz

REMOTE TRANSMITTER
You can lock and unlock your vehicle with the remote transmitter.
LOCK
When you push the LOCK button, all the doors will lock.
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 , all the doors will unlock.
You cannot unlock any of the doors with the remote transmitter if the key is in the ignition switch.
When you push the UNLOCK button more than about 1.0 second , the window will open.
PANIC MODE
Panic mode allows you to remotely sound your vehicle’s horn to attract attention. To activate this
mode , press and hold the PANIC button for about one seconds. 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 is in ON
