2005 CHEVROLET CAVALIER Owners Manual

One key is used for the
ignition, the doors and all
other locks.
When a new vehicle is delivered, the dealer removes
the key tag from the key and gives it to the rst owner.
Each tag has a code on it that tells your dealer or a
qualied locksmith how to make extra keys. Keep the
tag in a safe place. If you lose your key, you will be able
to have a new one made easily using the tag.
If you need a new key, contact your dealer who can
obtain the correct key code. SeeRoadside Assistance
Program on page 7-6for more information.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.If your vehicle is equipped with the OnStar®system with
an active subscription and you lock your keys inside
the vehicle, OnStar
®may be able to send a command to
unlock your vehicle. SeeOnStar®System on page 2-33
for more information.

2-3

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 “Battery
Replacement” and “Resynchronization” under
“Remote Keyless Entry System Operation” following
this section.
If you are still having trouble, see your dealer or a
qualied 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.
2-4

The following functions are
available with the remote
keyless entry system:
LOCK:Press this button to automatically lock all doors.
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.
SeeContent Theft-Deterrent on page 2-14.UNLOCK:Press this button to unlock the driver’s door.
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. SeeContent Theft-Deterrent on
page 2-14. If you press this button again within
ve seconds, all remaining doors will unlock.
V(Trunk Release):Press this button to open the
trunk. 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):Press this button to sound the horn and
make the headlamps and interior lamps ash alternately.
They can be turned off by pressing this 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 will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it is 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.
2-6

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 will not 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.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
conrms 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 — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not 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.There are several ways to lock and unlock your vehicle.
Use your key to lock and unlock your vehicle from
the outside. If your vehicle is equipped with a remote
keyless entry system, you can also use it to lock
and unlock your vehicle. SeeRemote Keyless Entry
System on page 2-3.
To lock the door from the
inside, push the locking
lever forward.
To unlock the door, pull the locking lever rearward.
2-8

Power Door Locks
If your vehicle has this
feature, you can lock or
unlock all the doors
on your vehicle from the
driver’s or front
passenger’s door
lock switch.
Press the lower portion of the switch to lock the doors.
Press the upper portion of the switch to unlock the doors.
The locking lever on each rear door works only
that door’s lock. It will not lock or unlock all of the
doors — that is a safety feature.
Rear Door Security Locks
If your vehicle is a
four-door model, it is
equipped with rear door
security locks that
help prevent passengers
from opening the rear
doors on your vehicle from
the inside.
Using the Rear Door Security Lock
1. Use a key to move the lock all the way up.
2. Close the door.
3. Do the same thing to the other rear door lock.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use.
2-9

Opening a Rear Door When the
Security Lock is On
1. Unlock the door from the inside.
2. Then open the door from the outside.
If you do not cancel the security lock feature, adults or
older children who ride in the rear will not be able to
open the rear door from the inside. You should let adults
and older children know how to cancel the locks.
Canceling the Rear Door Security Lock
1. Unlock the door from the inside and open the
door from the outside.
2. Use a key to move the lock all the way down.
3. Do the same for the other rear door.
The rear door lock will now work normally.
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 key is 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.
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, it is recommended that you use
two hands and from the center to ensure it latches fully.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot 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 Climate Control
System in the Index.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-29.
