2. GENERAL DESCRIPTION
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 select the following operations by pressing the
button of the remote transmitter.

3. REMOTE TRANSMITTER
You can lock and unlock your vehicle with the remote transmitter.
You cannot lock any of the doors with the remote transmitter if any door is
open or the key is the ignition switch.
•LOCK : When you push the LOCK button, all the doors will lock.
• UNLOCK : When you push the UNLOCK button, all the doors will unlock.
You cannot unlock any of the doors with the remote transmitter if any door
is open or the key is in the ignition switch.
•TRUNK : When you push the TAIL GATE button for 1.0sec, It will open.
•PANIC : When you push the PANIC button, horn will alarm.

5. FEATURES
Transmission frame. The transmission begins immediately in case of LOCK
and UNLOCK, PANIC button is pressed. The transmission frame consists of
the synchronous frame and the data frame. The synchronous frame has
320bit synchronous codes that it will be used for the receiver to wake up.
The data frame consists of 24bit length identification code, 16bit security
code and 4bit function code and 8bit CRC code. 16million different
identification codes are available. The security code is always changed in
case of any of the buttons is pressed. The transmission time is typically
300 milliseconds.
