2004 Oldsmobile Alero horn

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 is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
•If you are still having trouble, see your dealer or a
qualified 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.
The following functions are available with the keyless
entry system:
Q(Lock):Press this
button to lock all doors. The
interior lamps will turn off
after all of the doors
are closed. If all of the
doors are closed, the
parking lamps will flash
twice and the horn will chirp
to indicate locking has
occurred.
2-4

W(Unlock):Press this button once to unlock the
driver’s door. If the button is pressed again within five
seconds, all remaining doors will unlock. The interior
lamps will stay on for 10 seconds or until the ignition is
turned on. The parking lamps will flash twice to
indicate unlocking has occurred.
V(Remote Trunk Release):Press this button to
open the trunk, if 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), when the
parking brake is engaged, or when the ignition is off. The
interior lamps will come on for 10 seconds or until the
ignition switch is turned to ON.
L(Remote Alarm):Press this button to make the
horn sound and the headlamps and the parking lamps
flash for up to two minutes. The interior lamps will
come on and remain on while the horn is sounding and
the lamps are flashing. Turn off the horn and lamps
by pressing the remote alarm button again or by turning
the ignition to ON.
Programmable Horn Chirp
When you use the remote keyless entry transmitter to
lock the doors or use the delayed locking feature
the parking lamps will flash and the horn will chirp.
Disable the programmable horn chirp by pressing and
holding either of the door lock switches in the unlock
position for 10 seconds with the ignition ON and all of
the doors closed. When you hear the horn chirp,
programming is complete.
Reactivate the horn chirp feature by repeating the
above procedure.
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.
2-5

From the inside, you can lock or unlock the door by
moving the manual lever forward or rearward.
Power Door Locks
With the power door locks, you can lock or unlock all of
the doors on your vehicle using the driver’s or front
passenger’s door lock switch.
Press the bottom of the switch to lock all of the doors.
Press the top of the switch to unlock all of the doors.
Delayed Locking
This feature will allow the driver to delay the actual
locking of the vehicle. This feature will not operate if the
key is left in the ignition. SeeLockout Protection on
page 2-11.
With the key out of the ignition and the driver’s door
open, pressing LOCK on the driver’s power door
lock switch will not immediately lock the other doors.
Instead a seven second delay will start and three chimes
will be heard. Seven seconds after the driver’s door
has been closed, all of the doors will lock and the
parking lamps will flash. The horn will also chirp if the
horn chirp feature is enabled. See “Programmable Horn
Chirp” previously for more information.
If the driver opens another door before the seven
seconds, the doors will not lock until seven seconds
after the last door is closed.
Press LOCK twice on the power door lock switch on the
driver’s door to lock the doors without a delay or
press the LOCK button on the remote keyless entry
transmitter while all doors are closed.

Entry/Exit Lighting
The lamps inside your vehicle will go on when you open
any door. These lamps will fade out after about
10 seconds after all of the doors have been closed or
when the ignition is turned to ON. These lamps will also
go on when you press the trunk release, unlock
symbol button or the horn symbol on the remote keyless
entry system transmitter (if equipped).
The lamps inside your vehicle will stay on for about
10 seconds after your key is removed from the ignition
to provide an illuminated exit.
Dome Lamp
The switch on this lamp has three positions. The ON
position will turn on the light. The DOOR position
will turn on the light whenever a door is opened or when
the instrument panel brightness thumbwheel is moved
up. The OFF position will shut off the lamp completely,
even when a door is opened. If your vehicle is
equipped with a sunroof, the dome lamp also has
reading lamps for the rear seat passengers. Press the
left switch for the left reading lamp and the right
switch for the right reading lamp.
Trunk Lamp
The trunk lamp comes on when you open your trunk.
Battery Run-Down Protection
Your vehicle has a battery run-down protection feature
designed to protect your vehicle’s battery.
When any interior lamp (trunk, mirror reading lamps,
dome lamp or glove box) is left on when the ignition is
turned off, the battery saver system will automatically
shut the lamp off after 20 minutes. This will avoid
draining the battery.
To reactivate the interior lamps, do one of the following:
•Lift the driver’s door handle,
•open any door or
•press any remote keyless entry transmitter button (if
equipped),
•press the power door lock switch,
•press the remote trunk release or
•turn the lamp that was left on to off and then to on
again.
