2003 CHEVROLET CAVALIER lock

At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
·Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
·Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
·Check to determine if battery replacement or
resynchronization is necessary. See ªBattery
Replacementº and ªResynchronizationº under
ªRemote Keyless Entry System Operationº following
this section.
·If you are still having trouble, see your dealer or a
quali®ed technician for service.
Remote Keyless Entry System
Operation
If your vehicle has this feature, you can lock and unlock
your doors or unlock your trunk from about 3 feet
(1 m) up to 30 feet (9 m) away using the remote keyless
entry transmitter supplied with your vehicle.
In addition, the system illuminates the interior lamps for
a set period of time. Also, a content theft security
system can be activated to monitor and set a horn alarm
if the vehicle's door or trunk is opened without ®rst
unlocking the door or trunk with the remote keyless entry
transmitter.
The remote keyless entry system consists of a receiver,
which is located in the vehicle, and two hand held
transmitters.

The following functions are
available with the remote
keyless entry system:
LOCK:All doors will automatically lock when this
button is pressed. In addition, if all doors and the trunk
are closed, the headlamps will ¯ash once, the interior
lamps will turn off, and the vehicle content theft security
system will arm. See
Content Theft-Deterrent on
page 2-15.
UNLOCK:The driver's door will unlock when this button
is pressed. In addition, the headlamps will ¯ash twice, the
interior lamps will turn on for about 20 seconds or until the
ignition is turned on, and the content theft security system
will disarm. See
Content Theft-Deterrent on page 2-15.If
you press UNLOCK again within ®ve seconds, all
remaining doors will unlock.
V(Trunk Release):The trunk will unlock when this
button is pressed, as long as the trunk lockout is
not engaged. You can open the trunk with the
transmitter when the vehicle speed is less than 2 mph
(3 km/h). The headlamps will ¯ash twice.
L(Panic):The horn will sound and the headlamps
and interior lamps will ¯ash alternately when this button
is pressed. They can be turned off by pressing the
panic button again or by turning the ignition to ON. The
alarm will sound for two minutes unless cancelled by
the driver.
Your dealer can change the settings to disable the
headlamp ¯ash and horn chirp features. Your dealer can
also change the settings to allow the horn to chirp
twice on the ®rst press of the UNLOCK button. See your
dealer for more information.
Radio Personalization
Your vehicle can store different radio preset stations
depending on which keyless entry transmitter you use to
unlock the doors. The radio will recall all the stored
settings associated with that transmitter. Any radio
setting changes will be assigned to the transmitter last
used to unlock the doors.
This feature can be disabled by your dealer if you
desire. Contact your dealer for further information.

Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it's probably time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.To replace the battery in the transmitter:
1. Use a coin or similar object to separate the bottom
half from the top half of the transmitter.
2. Remove the battery and replace it with the new
one. Make sure the positive side of the battery
faces down. For battery replacement, use a
three-volt battery, type CR2032, or equivalent.
3. Read the instructions inside the case.
4. Put the two halves back together. Make sure the
cover is on tightly, so water won't get in.
5. Check the operation of the transmitter with your
vehicle. If the transmitter does not work, try
resynchronizing the transmitter with the receiver.
2-6

Resynchronization
Your remote keyless entry system is equipped with a
security system that prevents anyone from recording and
playing back your signal. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal that has been sent to it
more than once.
Normally, the transmitter and receiver resynchronize
automatically. However, under certain circumstances,
manual resynchronization may be required.
To resynchronize your transmitter and receiver, follow
these directions:
1. Stand close to your vehicle.
2. Press and hold the LOCK and UNLOCK buttons on
the transmitter at the same time.
3. Hold the buttons for at least 10 seconds. During this
time, the doors should lock and unlock once. This
con®rms the resynchronization. If the doors do
not lock and unlock, see your dealer for service.
Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
·Passengers Ð especially children Ð can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle won't open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors aren't locked. So,
wear safety belts properly and lock the
doors whenever you drive.
·Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
·Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.

Lockout Protection
If your vehicle is equipped with remote keyless entry,
you have lockout protection. This feature stops the
power door locks from locking when the keys are in the
ignition and the door is open.
If the power door lock switch is pressed when a door is
open and the key is in the ignition, all the doors will
lock and the driver's door will unlock.
Leaving Your Vehicle
If you are leaving the vehicle, open your door and set
the locks from the inside. Then get out and close
the door.
Trunk
To unlock the trunk from the outside, insert the key and
turn the trunk lock cylinder or use the remote keyless
entry transmitter if your vehicle has one.
When closing the trunk, close from the center to ensure
it fully latches. Although you may use one hand to
unlock the trunk, it is recommended that two hands on
the upper surface be used to close the trunk.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You can't see or smell
CO. It can cause unconsciousness and even
death. If you must drive with the trunk lid open
or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
·Make sure all other windows are shut.
·Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See ªClimate Control
Systemº in the Index.
·If you have air outlets on or under the
instrument panel, open them all the way.
