1. INTRODUCTION
This document is the technical specification of the remote keyless entry (RKE) System for the car
consisting of S&T (S&T Daewoo Co.,. LTD) receiver (RX), S&T transmitter (TX) and Horn.
The purpose of the S&T 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.
1.1 REMOTE KEYLESS ENTRY FUNCTION
remote keyless entry occur the follow function.
a. Remote door lock / unlock
b. Remote trunk Release
c. Vehicle locator
d. Onstar function
1.2 ANTI-THEFT FUNCTION
anti theft alarm system occurs the follow function.
a. Burglar alarm
b. Display the ATAS status using security indicator.
c. Safety lock

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).

When the ignition is off and the key reminder is off, the Rx drives panic function by the Tx
panic button. But it does not change the Rx status. For the information of the remote panic,
the hazard lamp blinks 28sec, the period is 0.5sec and duty ratio is 0.25sec, the horn operates
28sec, the period is 1sec and the duty ratio is 0.5sec
3.1.2 TRANSMITTER UNLOCK/LOCK/ 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 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 "TRUNK" Operating trunk solenoid
[Table 2. 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).
When the trunk function by the Tx trunk button operates, trunk solenoid is actuated for 500ms.
