Oldsmobile 1998 Aurora Owner's Manual page 83

If a door or the trunk is opened without the key or
remote lock control transmitter, the alarm will go off.
It will also go off if the trunk lock or door locks are
damaged. Your vehicle's lamps will flash and the horn
will sound for several minutes, then will go off to save
battery power.
Remember, the theft-deterrent system won't activate if
you lock the doors with a key or manual door lock. It
only activates if you use the power door lock switch or
remote lock control transmitter. You should also
remember that you can start your vehicle with the
correct ignition key if the alarm has been set off, but this
does not shut off the alarm.
Here's how to avoid setting off the alarm by accident:
If you don't want to activate the theft-deterrent
system, lock the door either using a key, or the
manual door lock switch.
Always unlock a door with a key, or use the remote
lock control system. Unlocking a door any other way
will set off the alarm.
I f you set off the alarm b y accident, unlock any door
with your key.
You can also turn off the alarm by pressing UNLOCK
on the remote lock control transmitter. The alarm won't
stop if you try to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, roll down the driver's
window and open the driver's door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote lock control transmitter.
3. Get out of the car, close the door and wait for the
SE.CURITY light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should, but the
vehicle's lamps flash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
see "Fuses and Circuit Breakers'' in the Index.
If the alarm does not sound, or the vehicle's lamps
do not flash, the vehicle should be serviced by an
authorized service center.
