2000 BUICK CENTURY key

2-7 Lockout Protection Feature
This feature prevents a driver who has left the key in the
vehicle's ignition from locking the doors by using the
power door locks while any door is open. The feature
works by disabling the power door locks when a key is
in the ignition and any door is open.
You may override the lockout protection feature by
holding the power door lock switch in the lock position
for more than three seconds while the key is in the
ignition and any door is open.
Remember, this feature can't guarantee that you'll never
be locked out of your vehicle. If you use the manual
door lock or if you don't leave the key in the ignition,
you could still lock your keys inside your vehicle.
Always remember to take your keys with you.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from inside. Then get out and
close the door. (Also see ªDelayed Lockingº in this
section for more information.)

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 the instructions that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation

advance the UNLOCK mode by one, starting from the
current unlock mode. If cycled beyond unlock Mode 4,
the vehicle will enter unlock Mode 1. During this
procedure, the feature will sound the number of chimes
corresponding to the current unlock mode, providing
you with feedback. When the door unlock switch is
released, the vehicle will remain in the most recent
unlock mode.
Disconnecting the vehicle's battery for up to a year will
not change the programmed mode of the lock and
unlock security feedback features.
Delayed Locking
Delayed locking allows the doors to be locked while
passengers are exiting the vehicle. This feature also
provides a brief time period after all the doors are
closed, but before the doors are locked, in which the
doors may be reopened. Delayed locking is user
programmable for enabling or disabling the feature.

2-11
Delayed locking is activated when a door lock switch is
pressed while the key is not in the vehicle's ignition, and
a door is open. The door lock switch may be either the
lock switch on the door or on the remote keyless entry
transmitter (see ªRemote Keyless Entryº later in this
section for more details). The doors do not lock when
the lock switch is pressed, but instead, three chimes are
heard. These chimes indicate that the delayed locking
feature has been activated.
You have three actions possible once delayed locking
is activated:

Cancel the delayed locking by pressing the unlock
switch or by fully inserting the key in the ignition.

Override the delayed locking feature and lock the
doors immediately by pressing the lock switch a
second time.

Let the delayed locking feature complete the locking
of the vehicle.
If you wish to let the delayed locking feature complete
the locking of the vehicle, no additional action is
required. The delayed locking feature will lock the doors
automatically after all the doors have been closed for a
period of five seconds. During this five second period,
any door may be reopened, at which time the three
possible actions shown above are again available.You may also customize your vehicle to activate the
delayed locking feature as described above, or you
may choose to completely disable the feature at all
times. If disabled, the power door locks will activate
immediately when a power door lock switch is pressed.
The enabled/disabled state of the delayed locking
feature will be toggled when you perform the following
sequence with the doors closed and the ignition key
in RUN:
1. Apply your regular brakes.
2. Press and hold the power door unlock switch. While
holding the door unlock switch, move the shift lever
out of and back into PARK (P).
After an initial transaxle cycle, each additional cycle will
toggle the enable/disable state of the delayed locking
feature. During this procedure, the chime will sound,
providing you with feedback. In Mode 1, a single chime
will be heard if the delayed locking feature is disabled.
In Mode 2, two chimes will be heard if the feature is
enabled. When the door unlock switch is released, the
vehicle will remain in the most recent operating mode.
Disconnecting the vehicle battery for up to a year will
not change the programmed mode of the delayed
locking feature.

2-12
Illumination on Remote Activation
This feature provides interior lighting when a remote
keyless entry door unlock command is received and
executed by your vehicle. Your ignition must be off for
the illumination on remote activation feature to work.
The interior lamps will light until either the ignition is
turned to RUN or a period of 40 seconds has elapsed.
If a door is opened during the illumination period, the
timed lighting will be canceled, and the interior lamps
will remain on since a door is open.
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 only four transmitters
matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's 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.

2-13
To replace the battery:
1. Insert a flat object like a dime into the slot on the
back of the transmitter. Gently pry apart the front
and back.
2. Remove the old battery and replace it with the new
one. (Use type CR2032 or an equivalent.) Make sure
the positive (+) side of the battery is facing down.
Do not use a metal object to remove the old battery.
3. Snap the top and bottom together, making sure the
halves are together tightly so water won't get in.4. Test the operation of the transmitter with
your vehicle. If the transmitter does not
work, try resynchronizing the transmitter.
(See ªResynchronizationº following.)
5. Resynchronize and then test the transmitter.
Resynchronization
Resynchronization may be necessary due to the
security method used by this remote keyless entry
system. The transmitter does not send the same
signal twice to the receiver. The receiver will not
respond to a signal it has previously been sent.
This prevents someone from recording and
playing back the signal from the transmitter.
To resynchronize the transmitter with the receiver,
do the following:
1. Stand close to your vehicle.
2. Simultaneously press and hold the LOCK and
UNLOCK buttons on the remote keyless entry
transmitter for about seven seconds.
There will be an audible confirmation when
resynchronization is done.
If the locks do not cycle, see your dealer for service.

2-14
Trunk
CAUTION:
It can be dangerous to drive with the trunk open
because carbon monoxide (CO) gas can come into
your vehicle. You can't see or smell CO. It can
cause unconsciousness and even death.
If you must drive with the trunk open or if
electrical wiring or other cable connections
must pass through the seal between the body
and the trunk:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on VENT. That will force outside air into
your vehicle. See ªComfort Controlsº in
the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Trunk Lock
To unlock the trunk from the outside, insert the door key
and turn it. You can also press the car symbol on your
remote keyless entry transmitter.
Remote Trunk Release
Press the button behind the
glove box door to unlock
the trunk from inside the
vehicle. The shift lever must
be in PARK (P) for the
remote trunk release button
to work.
