3. RKE FUNCTION
3.1 DOOR LOCK / UNLOCK USING TRANSMITTER
3.1.1 TRANSMITTER LOCK / UNLOCK/PANIC
This system function by using two buttons of the valid Tx is shown at Table 1. Now we define
the “VALID Tx” as the ID code (Fixed code + Crypto code) of the Tx is memorized by the
Control Unit.
Status Button Function
A Unset "UNLOCK" All door unlock, Hazard lamp blink twice, Disarming Mode
B Set "LOCK" All door lock, Hazard lamp blink once, Arming Mode
C Set/unset “PANIC” Horn and Hazard lamp blink 28sec
[Table 1. System Function by Using Two Buttons of the Valid Tx]
When the ignition is off, the key reminder is off and all doors(door / hood / trunk) are closed,
door lock by the Tx lock button. The Rx status goes to the arming mode in the condition of the
arming mode. For the information of the remote door lock, the hazard lamp blinks once for
0.5sec and the horn operates once 0.03sec.
When remote door lock is operated and not in the condition of the arming mode, hazard lamp
does not blink and horn does not operation because of not changing Rx status.
When the ignition is off and the key reminder is off, the Rx drives the door actuator in order to
unlock all doors by the Tx unlock button. The Rx status goes to the disarming mode. For the
information of the remote door unlock, the hazard lamp blinks twice, the period is 1sec and the
duty ratio is 0.5sec. But if there was the burglar alarm, the hazard lamp blinking period is 2s
(0.5sec On and 1.5sec Off).

3.2 BURGLAR ALARM
At the arming mode, if below signal input is recognized by the Rx, the burglar alarm (audible
alarm (horn) and visible alarm(hazard Lamp) ) is during 28 seconds operated and 5 seconds
paused. The alarm activating count is the option by customer.
① When the door open switch input is turned to low(GND) (at the moment of opening the door)
② When the hood open switch input is turned to low(OPEN) (at the moment of opening the
hood)
③ When the trunk open switch input is turned to low(GND) (at the moment of opening the
trunk)
④ When the ignition switch input is turned to high(BAT) (at the moment of IGN on)

If the above theft detection input is received at the arming mode, the type of theft is memorized at
the Rx EEPROM. But the alarm duration is not prolonged even if theft detection signal is
recognized during the alarm mode. That is, the Rx ignores the theft detection input until the
alarm is finished.
During the alarm is activated, if the “lock” , “unlock”, “trunk”, “panic” function code is received,
the Rx performs the function according to be received code and the burglar alarm (audible alarm
and visible alarm) is deactivated. If the “trunk” and “panic” function code is received, the Rx
does not perform the function and the burglar alarm is deactivated. And if the tamper switch
(passenger unlock disarming / driver unlock disarming / trunk unlock disarming) is ON, the Rx
stops the burglar alarm and goes to the disarming mode.

seconds after all door is unlocked by the Tx unlock button or the Tx door button, then all door is
locked again and the Rx also goes to the arming mode. At the case of the safety lock, even
though the Rx goes to the arming mode, the EEPROM data of the Rx about alarm is not changed.
If the remote door unlock is actuated again during the waiting time (30 seconds), the safety lock
process is restarted.
3.5 SECURITY INDICATOR
If the Rx status enters to the arming mode, the security indicator is blinking period 1sec (0.13sec
ON 0.87sec OFF).

The transmitter trans the high frequency signal using the PWM (Pulse Width Modulation)
method. The synchronization information, fixed information and switch information will be
encrypted to form the hopping code. The encrypted or hopping code portion of the transmission
will change every time a button is pressed, even if the same button is pushed again. Keeping a
button pressed for a long time will result in the same code word being transmitted until the button
is released or time-out occurs. If in the transmit process, it is detected that a new button is
pressed, the current code word will be aborted. A new code word will be transmitted and the
time-out counter will reset. If all the buttons are released, the minimum code words will be
completed.
