The ignition key is for
the ignition only.
The door key is for the
doors and all other locks.
The ignition and door keys don't have plugs. Your
dealer or Buick Roadside Assistance has the code for
your keys.If you need a new ignition or door key, contact
your dealer who can obtain the correct key code.
Also, see ªRoadside Assistanceº in the Index for
more information.
NOTICE:
Your vehicle has a number of features that can
help prevent theft. But you can have a lot of
trouble getting into your vehicle if you ever
lock your keys inside. You may even have to
damage your vehicle to get in. So be sure you
have extra 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. See ªOnStarº in
the Index for more information.

Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle 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.
Key in the Ignition
If you leave 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 vehicle and open the driver's door,
you'll hear a chime 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
Even if you park in a lot where someone will be
watching your vehicle, it's still best to lock it up and
take your keys. But what if you have to leave your
ignition key?

If possible, park in a busy, well
-lit area.

Put your valuables in a storage area, like your trunk
or glove box.

Be sure to close and lock the storage area.

Close all windows.

Lock the glove box.

Lock all the doors except the driver's.

Then take the door key and remote keyless entry
transmitter with you.

2-23
PASS-Key
II
Your vehicle is equipped
with the PASS
-Key II
(Personalized Automotive
Security System)
theft
-deterrent system.
PASS
-Key II is a passive
theft
-deterrent system.
It works when you insert
or remove the key from
the ignition.
PASS
-Key II uses a resistor pellet in the ignition key
that matches a decoder in your vehicle.
When the PASS
-Key II system senses that someone is
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 someone 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 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 is flashing, the key
may be dirty or wet. Turn the ignition off.Clean and dry the key. Wait about three minutes and try
again. If the starter still won't work, and the key appears
to be clean and dry, wait about three minutes and try
another ignition key. At this time, you may also want to
check the fuse (see ªFuses and Circuit Breakersº 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 dealer or a
locksmith who can service the PASS
-Key II.
If you accidentally use a key that has a damaged or
missing resistor pellet, the starter won't work. The
SECURITY light will then come on. But you don't have
to wait three minutes before trying another ignition key.
See your dealer or a locksmith who can service the
PASS
-Key II to have a new key made.
If you're ever driving and the SECURITY light comes
on, you will be able to restart your engine if you turn it
off. Your PASS
-Key II system, however, is not working
properly and must be serviced by your dealer. Your
vehicle is not protected by the PASS
-Key II system.
If you lose or damage a PASS
-Key II ignition key, see
your dealer or a locksmith who can service PASS
-Key II
to have a new key made. Also, see ªRoadside
Assistanceº in the Index for more information.

2-25
B (LOCK): This is the only position in which you
can insert or remove the key. This position locks the
ignition, steering wheel and transaxle. It's a
theft
-deterrent feature.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key;
if so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. Turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.
C (OFF): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel. Use OFF if you must have your vehicle pushed
or towed.D (RUN): This position is where the key returns to
after you start your vehicle. With the engine off, you
can use RUN to display some of your warning and
indicator lights.
E (START): This position starts your engine.
A warning chime will sound if you open the driver's
door when the ignition is in OFF, LOCK or
ACCESSORY and the key is in the ignition.
Retained Accessory Power (RAP)
(If Equipped)
With Retained Accessory Power (RAP), your
power windows, audio system and sunroof (if equipped)
will continue to work for up to 10 minutes after the
ignition key is turned to OFF and before any of the
doors are opened.

3-27 Theft-Deterrent Feature (If Equipped)
THEFTLOCK
is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is removed.
If THEFTLOCK is active, the THEFTLOCK will flash
when the ignition is off.
The THEFTLOCK feature for the radio may be used or
ignored. If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK is
activated, your radio will not operate if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate a locked condition anytime battery
power is removed. If your battery loses power for any
reason, you must unlock the radio with the secret code
before it will operate.
Activating the Theft

The instructions which follow explain how to enter
your secret code to activate the THEFTLOCK system.
It is recommended that you read through all nine steps
before starting the procedure.If you allow more than 15 seconds to elapse between
any steps, the radio automatically reverts to time and
you must start the procedure over at Step 4.

-digit number from 000 to
1999 and keep it in a safe place separate from the vehicle.
2. Turn the ignition to ACCESSORY or ON.

6. Press MIN again to make the last two digits agree
with your code.
7. Press HRS to make the first one or two digits agree
with your code.
8. Press AM
-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show REP to let you know that you
need to repeat Steps 5 through 7 to confirm your
secret code.

SEC to let you know that your radio is secure.
