1. INTRODUCTION
This document is the technical specification of the remote keyless entry (RKE) System for the car
consisting of DPI (Daewoo Precision Industries,. LTD) receiver (RX), DPI transmitter (TX) and
siren.
The purpose of the DPI RKE system is to provide the remote control function and the anti-theft
function in which it is installed and to prevent it from being driven by unauthorized users. The
verification of the user authorization is done by using a remote control operation with the
security code.
The diagnosis of the RKE is realized by the ALDL-function modes. They are realized by the
ALDL test equipment. To avoid manipulation of the usage of the test equipment, especially the
use of the key coding procedure has to be protected against unauthorized use.

3. RKE FUNCTION
3.1 DOOR LOCK / UNLOCK USING TRANSMITTER
3.1.1 TRANSMITTER LOCK / UNLOCK
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
[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 siren operates once 0.05sec.
When remote door lock is operated and not in the condition of the arming mode, hazard lamp
does not blink and Siren 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).

3.1.2 TRANSMITTER DOOR / TRUNK
This system function by using two buttons of the valid Tx is shown at Table 2. 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 set / unset "DOOR" all door lock or unlock
according to lock_monitoring status
B set / unset "TRUNK" operating trunk solenoid and
chirp operating(0.05sec on / 0.45sec off)
[Table 2. System Function by Using Two Buttons of the Valid Tx]
When the ignition is off, the key reminder is off, all doors (door / hood / trunk) are closed and the
lock_monitoring signal is GND, door lock by the Tx door 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 siren operates once 0.05sec.
When remote door lock is operated and not in the condition of the arming mode, hazard lamp
does not blink and Siren does not operation because of not changing Rx status.
When the ignition is off, the key reminder is off and the lock_monitoring signal is open, the Rx
drives the door actuator in order to unlock all doors by the Tx door 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).
When the trunk function by the Tx trunk button operates, trunk solenoid is actuated for 500ms.
For the information of the remote trunk open, the siren operates twice, the period is 0.5sec
(0.05sec on 0.45sec off). But it does not change the Rx status.

3.2 BURGLAR ALARM
At the arming mode, if below signal input is recognized by the Rx, the burglar alarm (audible
alarm (siren) and visible alarm(hazard Lamp) ) is activated 8 times 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”, “door” 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” 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.

3.4 SAFETY LOCK(AUTO DOOR LOCK AFTER 30SEC)
At the arming mode, if the door / trunk / hood open and the ignition on is not occurred during 30
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 (0.12sec
ON 0.88sec OFF).
Security Indicator RKE & ATAS Status
Blinking(f=1Hz) Duty cycle 1:7(ON/OFF) Arming, Trunk Rearming State
OFF Disarming Status
[Table 3. Security Indicator Operating timing Chart]
3.6 DIAGNOSTIC
Communication between the ECU and the diagnostic tester takes place in accordance with
ISO9141-2, with line K only but without line L. Line K is a bidirectional data line used to convey
request messages from the diagnostic tester to the ECU and response messages from the ECU to
the diagnostic tester. Additional DIAGNOSTIC function refers to the document
SPECIFICATION #DPE-AE-RK509603S Keyless Entry System Diagnostic Specification.
3.7 ACTIVE RANGE
Active functions of the receiver shall be operable when the Tx is with in the specified range of
the vehicle, as follows:

4.2.3 TRANSMITTER FUNCTION
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.
4.2.4 BATTERY
Battery removal shall be able to be performed without specialized tools. Average time to replace
a battery shall be less than 5 minutes. No damage to the transmitter shall result if the batteries

are installed backwards. Battery replacement shall not require the customer to handle any loose
components (i.e. circuit boards, battery clips, etc.).
Battery life shall exceed 2 years at 25°C based on usage specified in section 3.1.1, with
transmission time corresponding to 1 second duration button press activations.
4.2.5 LED
During the normal transmission the led operating is ON. If the supply voltage drops below the
low voltage trip point, the led is toggled at approximately 5Hz during the transmission.
