Theft
Vehicle theft is big business, especially in some cities.
Although your Buick has a number of theft deterrent
features, we know that nothing we put on
it can make it
impossible to steal. However, there are ways you can
help.
Kev in the ignition: If you walk away from your
vehicle with the keys inside, it’s an easy target for joy
riders or professional thieves
-- so don’t do it.
When you park your Buick and open the driver’s door,
you’ll hear a tone reminding you to remove your key
from
the ignition and take it with you. Always do this.
Your steering wheel will be locked, and
so will your
ignition and transaxle. And remember to lock the doors.
Parking at Night: Park in a lighted spot, close all
windows and lock your vehicle. Remember
to keep your
valuables
out of sight. Put them in a storage area, or take
them with you.
Parking. Lots: If you park
in a lot where someone will
be watching your vehicle, it’s best to lock
it up and take
your keys. But what if you have
to leave your ignition
key? What if you have to leave something valuable
in
your vehicle?
Put your valuables in a storage area, like your trunk

0 Then take the door key with you.
Universal Theft Deterrent (Option)
If your Buick has this option, it has a theft deterrent
alarm system. With this system, the “SECURITY’’ light
will flash as
you open the door (if your ignition is off).
This light reminds you
to arm the theft deterrent system.
Here’s how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
Remote Keyless Entry System. The “SECURITY”
light should come on
and stay on.
3. Close all doors. The “SECURITY” light should go
off.
If a door or the trunk is opened without the key or
Remote Keyless Entry System, the alarm will
go off. It
will also
go off if a door lock or the trunk lock is
damaged. Your vehicle’s lights will flash and the horn
71
ProCarManuals.com

will sound for several minutes, then will go off to save
battery power.
Remember, the theft deterrent system won’t arm if you
lock
the doors with a key or manual door lock. It arms
only if you use
a power door lock switch or Remote
Keyless Entry System. You should also remember that
you can start your vehicle with the correct ignition key
if the alarm has been set
off. You must still shut off the
alarm by inserting the key’in the door lock.
Here’s how to avoid setting
off the alarm by accident:

0
If you don’t want to arm the theft deterrent system,
the vehicle should be locked after the doors are
closed.
Always unlock a door with’a key, or use the Remote
Keyless Entry System. Unlocking a door any other
way will set
off the alarm. If
you set
off the alarm by accident, unlock any door
with your
key.
You can also turn off the alarm by using the Remote
Keyless Entry System,
if you have it. The alarm won’t
stop
if you try to unlock a door any other way.
How to Test The Alarm
The alarm can be tested by first having the driver’s
window down. Arm
the system by locking the doors
with the power door lock switch or the Remote Keyless
Entry System. Get out
of the car and close the door, wait
for the security light to go out, then reach in through the
window, unlock the door with the manual door lock,
then open the door. This should set the alarm off.
If the alarm does not sound when
it should, 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.

PASS-Key I1 TM
Your vehicle is equipped with the PASS-Key I1 TM
(Personalized Automotive Security System) theft
deterrent system. PASS-Key
I1 TM is a passive theft
deterrent system. This means you don’t have to do
anything different to arm or disarm the system. It works
when you insert or remove the key from the ignition.
PASS-Key
TM uses a resistor pellet in the ignition key
that matches a decoder in your vehicle. When the PASS-Key
I1 system senses that someone
using the wrong key, it shuts down the vehicle’s starter
and
fuel systems. For about three minutes, the starter
won’t work and fuel won’t go to the engine. If someonl
tries to start your vehicle again or uses another key
during this time, the vehicle will not start. This
discourages someone from randomly trying different
is
e
keys with different resistor pellets in an attempt to make
a match.
The ignition
key must be clean and dry before it’s
inserted in the ignition or the engine may not start. If the
engine does not start and the “SECURITY” light comes
on, the key may be dirty or wet. Turn the ignition
off.
Clean and dry the key. Wait about three minutes and try
again. The security light will remain on during this time.
If the starter still won’t work, and the key appears to be
clean and dry, wait about three minutes and try the other
ignition key.
At this time, you may also want to check
the fuse (see “Fuses and Circuit Breakers” in the Index).
If the starter won’t work with the other key, your vehicle
needs service. If your vehicle does start, the first ignition
key may
be faulty. See your Buick dealer or a locksmith
who can service the PASS-Key I1
TM .
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won’t work and the

security light will flash. But you don’t have to wait three
minutes before trying one of the other ignition keys.
See your Buick dealer or a locksmith who can service
the Pass-Key I1
TM to have a new key made.
If you’re ever driving and the “SECURITY” light comes
on for one minute and stays on, you will be able to
restart your engine if
you turn it off. Your PASS-Key
I1
TM system, however, is not working properly and must
be serviced by your Buick dealer. Your vehicle
is not
protected by the PASS-Key I1
TM system.
If you
lose or damage a PASS-Key I1 ignition key, see
