2000 BUICK PARK AVENUE change key battery

2-9
Changes or modifications to this system by other than an
authorized service facility could void authorization to
use this equipment.
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 or
synchronization is necessary. See the instructions
that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.
Operation
The numbers on the back of the transmitters correspond
to DRIVER #1 and DRIVER #2 on the DIC
(if equipped). See ªDICº in the Index for
more information.
The driver's door
will unlock when the
button with the unlock
symbol is pressed. If
pressed again within
five seconds, all the
doors will unlock.
Pressing any button will also illuminate the interior
lamps (see ªIlluminated Entryº in the Index).
All doors will lock when the button with the lock
symbol is pressed.
The trunk will unlock when the trunk button is pressed,
and the ignition is in LOCK or OFF. The trunk button
will also work when the ignition is on, but only while
the transaxle is in PARK (P).

2-11
Vehicles are delivered programmed in Mode 5;
however, each remote keyless entry transmitter can be
programmed to a different mode according to the user's
preference. To change to another mode:
1. Press and hold LOCK on the power door lock switch
on the door throughout the procedure.
2. Press the trunk button on the transmitter. The horn
will chirp and the transmitter will remain in its
current mode.
3. Press the trunk button again. Each time the trunk
button is pressed, the horn will chirp and the
transmitter will advance to the next mode.
4. Release the power door lock switch.
If your vehicle is equipped with the Driver Information
Center (DIC), you can also program these features
through the DIC. See ªDriver Information Centerº
in the Index.
Theft
-Deterrent System
The remote keyless entry transmitter will arm the
theft
-deterrent system whenever the doors are closed
and you push the button with the lock symbol when the
ignition is off. It will disarm the system when you push
the button with the unlock symbol.
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.
See your dealer to match additional transmitters to
your vehicle.
Battery Replacement
Under normal use, the battery in your transmitter should
last about four 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:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive
heat can damage your starter motor. Wait about
15 seconds between each try to help avoid
draining your battery or damaging your starter.
2. If it doesn't start right away, hold your key in
START for about three to five seconds at a time until
your engine starts. Wait about 15 seconds between
each try to help avoid draining your battery or
damaging your starter.
3. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briefly but then stops again, do the same thing, but
this time keep the pedal down for five or six seconds.
This clears the extra gasoline from the engine.
After waiting about 15 seconds, repeat the normal
starting procedure.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
If you ever have to have your vehicle towed,
see the part of this manual that tells how to do it
without damaging your vehicle. See ªTowing
Your Vehicleº in the Index.
Engine Coolant Heater (If Equipped)
In very cold weather, 0
F (-18
C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm
-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.
