2003 GMC YUKON DENALI key battery

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
page

If you are still having trouble, see your dealer or a
qualified technician for service.
Remote Keyless Entry System
Operation

(1 m) up to 100 feet (30 m) away using the remote
keyless entry transmitter supplied with your vehicle.
a (Unlock): Pressing this
button once will unlock the

within three seconds will
cause the remaining doors
to unlock.
You can choose different feedback options for each

perimeter lamps come on and/or having the horn
chirp. See
DIC Operation and Displays on page 3-43 for
more information.

doors. Pressing the button again within three seconds
may cause the horn
to chirp for lock confirmation.
You can choose different feedback options for each
press of the lock button, such as having the vehicle’s
perimeter lamps flash and/or having the horn chirp. See
DIC Operation and Displays on page 3-43 for more
information.
& (Panic): When this button is pressed, the horn will
sound and the headlamps and taillamps will flash for
up

starting the vehicle.
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,

Theft-Deterrent Systems
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.
Content Theft-Deterrent
Your vehicle is equipped with a content theft-deterrent
alarm system.
With this system, the
security light in the instrument panel cluster
will flash as you open
the door
if your ignition
is
off.
This light reminds you to activate the theft-deterrent
system. Here’s how
to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The security
light should come
on and stay on.
3. Close all doors. The security light should go off
after about 30 seconds. The alarm is not armed
until the security light goes
off.
If a locked door is opened without the key or the remote
keyless entry transmitter, the alarm will
go off. The
headlamps and parking lamps will flash for
two minutes,
and the horn will sound for
30 seconds, then will turn
off to save the battery power. You can choose different
feedback options for the alarm. See Driver lnformation
Center
(DIC) on page 3-43.
Remember, the theft-deterrent system won’t activate if
you lock the doors with a key or use the manual
door lock.
It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct ignition key
if
the alarm has been set off.
Here’s how to avoid setting off the alarm by accident:
If you don’t want to activate the theft-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.
Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set
off the alarm.
If you set
off the alarm by accident, unlock any door with
the key. You can also turn
off the alarm by pressing
unlock on the remote keyless entry transmitter. The alarm
won’t stop
if you try to unlock a door any other way.
2-1 6

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? Turn the key only with
your hand. Using a tool to force
it could break the
key or the ignition switch.
If none of these works,
then your vehicle needs service.
B (ACCESSORY): This position allows you to use
things like the radio, power windows and the windshield
wipers when the engine is
off.
C (RUN): This position is for driving.
D (START): 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 for up
to 10 minutes after the ignition key is turned
to LOCK.
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
transaxle. 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.
When starting your engine in very cold weather
(below
0°F or -18”C), do this:
1. With your foot off the accelerator pedal, turn the
ignition key to START and hold it there up
to
15 seconds. When the engine starts, let go of
the key.
