2003 CHEVROLET MONTE CARLO change key battery

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.
To replace the battery do the following:
1. Insert a ¯at object like a coin into the slot on the
back of the transmitter. Gently pry apart the front
and back.
2. Gently pry the battery out of the transmitter. Do not
use a metal object.
3. Put the new battery into the transmitter as shown
on the transmitter. Use type CR2032 battery or
equivalent.
4. Put the two halves back together. Make sure the
halves are together tightly so water won't get in.
5. Resynchronize and then test the transmitter.
Resynchronization
After you have changed the battery in your transmitter,
you will need to resynchronize the transmitter. To
do this, press the LOCK and UNLOCK buttons on the
transmitter at the same time and hold for about
seven seconds or until one horn chirp is heard.

Power Door Locks
A power door lock switch
is located on each front
door above the armrest.
Press the top of the switch to unlock both doors, or
press the bottom of the switch to lock both doors.
If your vehicle has the optional content theft-deterrent
system and it is armed, the power door lock switches will
be disabled. You must use your remote keyless entry
transmitter or your key to unlock the doors while
the system is armed.
Programmable Automatic
Door Locks
Programmable automatic power door locks are a
standard feature that is intended to provide enhanced
security and convenience by automatically locking
and unlocking doors.
Programmable Modes
Mode 1:No automatic door lock or unlock.
Mode 2:Automatic all-door lock when the transaxle
is shifted out of PARK (P); no automatic door unlock.
Mode 3:Automatic all-door lock when the transaxle
is shifted out of PARK (P); automatic unlock for
the driver's door only when the transaxle is shifted
into PARK (P).
Mode 4:Automatic all-door lock when the transaxle
is shifted out of PARK (P); automatic all-door unlock
when the transaxle is shifted into PARK (P).
Before your vehicle was shipped from the factory, it was
programmed to Mode 4. The mode to which the vehicle
was programmed may have been changed since it left
the factory. To determine the mode to which your vehicle
is programmed or to program your vehicle to a different
mode, see
Vehicle Personalization on page 2-41.
Disconnecting the vehicle's battery for up to a year will
not change any previously programmed modes.

Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position Ð that's a
safety feature. To restart when you're already moving,
use NEUTRAL (N) only.
Notice:Don't try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transaxle. Shift to PARK (P) only when your
vehicle is stopped.
Starting Your 3400 V6 Engine
1. With your foot off the accelerator pedal, turn your
ignition key to START. When the engine starts, let
go of the key. The idle speed will go down as
your engine warms up.
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 the engine doesn't start in 10 seconds, push the
accelerator pedal about one-quarter of the way
down while you turn the key to START. Do this until
the engine starts. As soon as it does, let go of
the key.
3. If your engine still won't start (or starts but then
stops), it could be ¯ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
¯oor and holding it there as you hold the key in
START for a maximum of 15 seconds. This clears
the extra gasoline from the engine. If the engine
still won't start or starts brie¯y but then stops again,
repeat Step 1 or 2, depending on temperature.
When the engine starts, release the key and the
accelerator pedal.
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.
