key battery GMC SIERRA DENALI 2003 Owners Manual

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 “Battery Replacement” under
Remote Keyless Entry System Operation on

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 a maximum of four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two 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 in the keyless entry transmitter,
do the following:
1. Insert a thin coin, or similar object, in the slot
between the covers
of the transmitter housing
near the key ring hole. Remove the bottom
by twisting the coin.
CR2032 or equivalent battery, positive
(+) side up.
2. Remove and replace the battery with a three-volt
3. Align the covers and snap them together.
4. Check the operation of the transmitter.

LOCK (A): This position locks your ignition and
transmission. It’s a theft-deterrent feature. You will only
be able to remove your key when the ignition is
turned to
LOCK.
ACCESSORY (B): This position lets you use things like
the radio, power windows and the windshield wipers
when the engine is
off.
RUN (C): This position is for driving.
START
(D): This position starts your engine.
Retained Accessory Power (RAP)
The Retained Accessory Power (RAP) feature will allow
certain features on your vehicle to continue to work
up to
10 minutes after the ignition key is turned to OFF.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position - 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
transmission. Shift to PARK (P) only when your
vehicle
is stopped.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm.
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 within 10 seconds, push the
accelerator pedal all the way
to the floor, while you
hold the ignition key in START. When the engine
starts, let
go of the key and let up on the accelerator
pedal. Wait about
15 seconds between each try.

Battery Warning Light Voltmeter Gage
If this light is displayed
when the engine is
running, you may have a
problem with your charging
system.
The battery display will also stay on while the key is in
RUN until the engine is started.
If the light stays on after starting the engine it could
indicate a problem with the generator drive belt, or some
other charging system problem. Have it checked right
away. Driving with this light displayed could drain
your battery.
If you must drive a short distance with this light
displayed, it helps to turn
off all your accessories, such
as the radio and the air conditioner. When your
engine is not running, but the ignition is in
RUN, this gage shows your battery’s state of charge in
DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings between the
low and high warning zones indicate the normal
operating range.
Readings in the low warning zone may occur when a
large number
of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition
is normal since the
charging system is not able to provide full power
at engine idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
