DESCRIPTION AND OPERATION
DOOR LOCK STRIKER
The front and the rear door lock strikers each consist of
a striker with two screws threaded into a floating cage
plate in the B-pillars and C-pillars. The door is secured in
the closed position when the door lock fork snaps over
and engages the striker.
CHILDPROOF REAR DOOR LOCK
The childproof rear door locks help prevent passengers,
especially children, from opening the rear doors of the
vehicle from the inside.
In order to activate these locks, move the levers of both
rear doors to the lock position. Then, close both doors.
Rear passengers will be unable to open the doors from
the inside of the vehicle.
In order to deactivate the childproof rear door lock, un-
lock the door from the inside of the vehicle and open the
door from the outside. Move the lever to the unlock posi-
tion. The rear door will now work normally.
POWER DOOR LOCKS
The power door locks use a solenoid that is contained in
each door lock assembly. The door locks are activatedby the actuator on the inside door handle or by the lock
cylinder on the driver door only. When the driver door is
locked or unlocked by the actuator or lock cylinder, all
doors are locked or unlocked accordingly.
POWER WINDOWS
The power windows are controlled by electrical switches
on the front door tirm and operated by a motor at each
window regulator. The windows are lowered by pressing
the switch and raised by pulling up on the switch. The
window will stop movement when the switch is released
or when the window is completely open or closed.
TAILGATE STRUT
This vehicle is equipped with the gas struts. The struts
support the tailgate suitably when opening the tailgate.
The strut contained the high pressure compressed gas.
Therefore, be careful not to take apart, puncture, apply
heat or fire bacause the strut may explode.

DOOR LOCK STRIKER ADJUSTMENT
Notice: The door lock striker is an important attaching
part that can affect the performance of vital components
and systems and can cause major repair expenses. If
replacement becomes necessary, the door lock striker
must be replaced by one with the same part number or
with an equivalent part if replacement becomes neces-
sary. Do not use a replacement part of lesser quality or
of a substitute design. The specified torque values must
be used during reassembly in order to ensure the proper
retention of the part.
The door lock striker consists of a striker with two
screws that are threaded into a tapped, floating cage
plate located in the appropriate body pillar. This floating
cage plate allows the striker to be easily adjusted in or
out and up or down. The door is secured in the closed
position when the door lock fork snaps over and en-
gages the striker.
D19C575A
Fore/Aft Adjustment
1. The door must be properly aligned.
2. Close the door until the lock fork contacts the striker.
3. Stand next to the door opening and move the door
slowly in and out, just touching the striker each time.
D109C576
4. The alignment of the lock fork and the striker can be
easily seen. The lock fork should be perpendicular to
and fall near the middle of the striker. The lock fork
should fall near the middle of the striker between the
B-pillar and the end of the striker.

DAEWOO M-150 BL2
The tailgate lock striker consists of a striker with two
screws that are threaded into a tapped, floating cage
plate located in the appropriate body pillar. This floating
cage plate allows the striker to be easily adjusted in or
out and up or down. The tailgate is secured in the closed
position when the tailgate lock fork snaps over and en-
gages the striker.
D109C578
Fore/Aft or In/Out Adjustment
An adjustment of the striker in the fore and aft or in and
out directions may be necessary for a number of reasons:
vehicle frame damage as the result of a collision, installa-
tion of new tailgate weatherstripping, customer com-
plaints of excessive windnoise, or difficulty in opening or
closing the tailgate. In order to adjust the tailgate striker in
an fore and aft or in and out direction, perform the follow-
ing procedure:
1. The tailgate must be properly aligned.
2. Loosen the striker screws.
3. The floating cage plate can be moved slightly using
the ends of the striker screws. Move the floating cage
plate to the desired position.
Notice: It is important to use a flat-end rotary file in or-
der not to damage the tapped floating cage plate. The
striker screws and the tapped floating cage plate are im-
portant attaching parts that could affect the performance
of vital components and systems.
D109C579
4. If proper adjustment requires that the floating cage plate
be moved more than is possible, use an electric hand
drill and a 3/8- inch rotary file with a flat head in order to
enlarge the body opening in the direction required.
5. Tighten the striker screws to the correct position.
6. Perform the up/down adjustment. Refer to “Up and
Down Adjustment” in this section.

9T–2 REMOTE KEYLESS ENTRY AND ANTI-THEFT SYSTEM
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
REMOTE KEYLESS ENTRY AND
ANTI-THEFT SYSTEM
The remote keyless entry and anti-theft system can per-
form the following functions:

Remotely lock and unlock the vehicle doors with a
hand-held high-frequency transmitter.

Sense intrusion into the vehicle through the doors,
the tailgate, or the hood.

Activate a warning to signal an intrusion.

Help the driver find the vehicle in a parking area.

Automatically re-lock the doors if a door or the trunk is
not opened within 30 seconds after the vehicle has
been unlocked by the remote keyless entry.

Communicate serial data to a scan tool to help diag-
nose system faults.
The remote keyless entry and anti-theft system consists
of the following components:

Keyless entry and anti-theft control module/receiver.

Security indicator.

Tailgate open switch.

Door open switches.

Central locking unit.

Flashing turn signal lamps.

Siren.

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 transmit-
ter 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
button which only function when the ignition is OFF.
Pressing the UNLOCK button has the following effects:

The doors are unlocked.

The turn signal lamps flash twice.

The control module is disarmed.
Pressing the LOCK button has the following effects:

The doors are locked.

The turn signal lamps flash once.

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. Af-
ter 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 1/8
second and OFF for 7/8 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, the door, or the tailgate is opened, the
hood open switch, the door open switch, or the tailgate
open switch will change its input to ground. The alarm
will be activated if the hood open sensor, the door open
sensor, or the tailgate open sensor changes its input to
ground before either of the following conditions occurs:

An UNLOCK message is received from the transmit-
ter.
SIREN
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 ac-
tivate the siren and flash the turn signals for 28 seconds
if any of the following conditions occurs:

A door is opened (front door open switch input is
changed to ground).

The tailgate is opened (tailgate open switch input is
changed to ground).

The hood is opened while the anti-theft system is
armed (hood open switch input is changed to
ground).
The siren is disarmed when any of the following condi-
tions occurs:

The ignition switch is turned ON with the key.

The UNLOCK button or the LOCK button on the re-
mote transmitter is pressed.
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 length of time between flashes is used to indi-
cate certain vehicle conditions. Refer to “Fault or Alarm
Indication” in this section.
