TRANSMITTER PROGRAMMING
The Remote Keyless Entry System allows for the use of
as many as four(4) transmitters for each vehicle. Replace-
ment Remote Keyless Entry System Transmitters must
first be programmend to specific vehicle using the
Scan100 Secan tool.
This process is completed using serial data communica-
tion between the Scan 100 Scan tool and the Remote Key-
less Entry Control Unit and is the only method available for
programming Transmitters.
Notice : All Transmitters for a specific vehicle must be pro-
grammed at same time.
Notice : Once the programming function of the Remote
Keyless Entry System is activated, any Transmitter(exist-
ing or new) that is not programmed(or reprogrammed)
during the programming procedure will no longer operate
the Remote Keyless Entry System of that vehicle.
Notice : Ensure that the doors, hood and trunk/rear hatch
are closed prior to starting the programming procedure.

DAEWOO V–121 BL4
GENERAL DESCRIPTION
AND SYSTEM OPERATION
REMOTE KEYLESS ENTRY AND
ANTI–THEFT SYSTEM
The remote keyless entry and anti–theft system can per-
form the following functions:
S Remotely lock and unlock the vehicle doors by
means of a hand–held, high–frequency transmitter.
S Sense intrusion into the vehicle.
S Activate a warning in the event of an intrusion.
S Help the driver find the vehicle in a parking area.
S Automatically re–lock the doors if the door or the
trunk is not opened within 30 seconds after the ve-
hicle has been unlocked by the remote keyless
entry.
S Communicate serial data to a scan tool to help
diagnose system faults.
The remote keyless entry and anti–theft system consists
of the following components:
S Keyless entry and anti–theft control module/receiv-
er.
S Security indicator.
S Trunk open switch (NOTCHBACK).
S Trunk tamper switch (NOTCHBACK).
S Front door tamper switches.
S Door contact switches.
S Central door lock relay.
S Turn signal bulbs.
S Siren.
S Hood open switch.
REMOTE LOCKING AND UNLOCKING
The hand–held transmitter locks and unlocks the vehicle
doors by sending radio waves to the control module/re-
ceiver in the vehicle. The effective range of the transmitter
varies between 5 and 10 meters, (approximately 16 to 32
feet), depending on whether or not objects, such as other
vehicles are blocking the path of the radio waves.
The transmitter has a LOCK button and an UNLOCK but-
ton which only function when the ignition is OFF. Pressing
the UNLOCK button has the following effects:
S The doors are unlocked.
S The turn signal bulbs flash twice.
S The control module is disarmed.
Pressing the LOCK button has the following effects:
S The doors are locked.
S The turn signal bulbs flash once.
S The control module is armed.
The transmitter has a replaceable battery. The battery is
designed to last at least two years before replacement is
necessary.
SECURITY INDICATOR
There is a security indicator on the instrument panel. After
the LOCK button of the transmitter is pressed, the module
is placed in the armed mode, and the security indicator
flashes. The security indicator turns ON for 0.1 second
and OFF for 0.7 second. It then flashes at that frequency
until the control module/receiver is disarmed.
INTRUSION SENSING
The anti–theft function is armed if the transmitter sends
the LOCK message to the control module/receiver when
the ignition is OFF. When the hood, door, or trunk is
opened, the hood open, door contact, or trunk open switch
sends a ”ground” signal to the control module/receiver.
Unless the control module/receiver is disarmed, the siren
will be activated when the ”ground” signal is received from
the trunk open, hood open, or door contact switches.
The following actions disarm the anti–theft system:
S An UNLOCK message is received from the trans-
mitter.
S Key operation is detected by the tamper switches.
(The tamper switches are operated by the lock cyl-
inders in the front doors and trunk.)
The alarm will also be activated if the control module/re-
ceiver detects voltage from the ignition before either of the
following conditions occur:
S An UNLOCK message is received from the trans-
mitter.
S Key operation is indicated by the tamper switches.
SIREN (GENERAL ONLY)
The remote keyless entry system is armed when the
LOCK message is received from the transmitter when the
ignition is OFF. When the system is armed, it will activate
the siren and flash the turn signals for 28 seconds if any
of the following conditions occur:
S Close all the windows.
S Turn the ignition key to LOCK and remove the key.
S Have all passengers get out of the vehicle.
S Close all doors, the hood and the turnk lid.
S The control module/receiver detects ignition voltage
while the system is armed.
The siren will not operate if any of the following conditions
occur after the system has been armed:
S The door is opened with the key.
S The trunk is opened with the key.
S The UNLOCK or LOCK button on the remote trans-
mitter is pressed within 2 seconds after the siren is
activated.
VEHICLE LOCATOR
The remote keyless entry system assists the driver in lo-
cating the vehicle. When the vehicle is unlocked with the
remote control, the turn signals flash twice to indicate the
location of the vehicle. The duration of the flashes and the

REMOTE KEYLESS ENTRY AND ANTI–THEFT SYSTEM 9T1 – 9
DAEWOO V–121 BL4
length of time between flashes is used to indicate certain
vehicle conditions. Refer to ”Fault or Alarm Indication” in
this section.
AUTOLOCKING (SAFETY LOCK)
The remote keyless entry system features an autolocking
feature. If the doors are unlocked with the remote transmit-
ter when the control module/receiver is in the armed
mode, the doors are automatically re–locked after 30 sec-
onds unless any of the following events occur:
S A door is opened.
S The ignition is ON.
S The trunk is opened.
S The hood is opened.
CONTROL MODULE/RECEIVER
The remote keyless entry control module/receiver is con-
tained in the floor console. The module/receiver pro-
cesses signals from the remote transmitter and various
switches. It activates the alarm if an intrusion is detected.
The control module/receiver also has a self–diagnostic
function which will display trouble codes. In order to dis-
play trouble codes, a scan tool must be connected to the
data link connector (DLC).
The control module/receiver will not communicate with
transmitters from other vehicles because there are over
four billion possible electronic password combinations. Itis highly unlikely that any transmitters will use the same
password. The control module/receiver has an attached
antenna to detect signals from the transmitter.
FAULT OR ALARM INDICATION
When the UNLOCK button on the remote transmitter is
pressed, the control module/receiver will flash the parking
lights to indicate information about the remote keyless
entry and anti–theft system.
Normal Condition: If there has not been an intrusion, and
no fault has been detected, the control module/receiver
will signal a normal condition when the UNLOCK button is
pressed. The parking lights will flash twice for 0.5 second,
with a 0.5 second pause between flashes.
Fault Indication: If there is a fault in the remote keyless
entry and anti–theft system, the control module/receiver
will signal the fault when the UNLOCK button is pressed.
The parking lights will flash twice for 1 second, with a 0.5
second pause between flashes.
Alarm Indication: If there has been an intrusion since the
last time the LOCK button was pressed, the control mod-
ule/receiver will signal that there has been an intrusion
when the UNLOCK button is pressed. The parking lights
will flash twice for 0.5 second, with a 1.5 second pause be-
tween flashes.
Alarm and fault information will be erased the next time the
transmitter arms the control module/receiver by transmit-
ting a LOCK message.
