2004 GMC YUKON DENALI key

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 ªBattery Replacementº under
Remote Keyless Entry System Operation on
page 2-5.
·If you are still having trouble, see your dealer or a
quali®ed technician for service.
Remote Keyless Entry System
Operation
You can lock and unlock your doors from about 3 feet
(1 m) up to 100 feet (30 m) away using the remote
keyless entry transmitter supplied with your vehicle.
K(Unlock):Pressing this
button once will unlock the
driver's door. The interior
lamps will come on.
Pressing unlock again
within three seconds will
cause the remaining doors
to unlock.
You can choose different feedback options for each
press of the unlock button, such as having the vehicle's
perimeter lamps come on and/or having the horn
chirp. See
DIC Operation and Displays on page 3-46for
more information.
2-5

Q(Lock):Pressing this button once will lock all of the
doors. Pressing the button again within three seconds
may cause the horn to chirp for lock con®rmation.
You can choose different feedback options for each
press of the lock button, such as having the vehicle's
perimeter lamps ¯ash and/or having the horn chirp. See
DIC Operation and Displays on page 3-46for more
information.
L(Panic):When this button is pressed, the horn will
sound and the headlamps and taillamps will ¯ash for
up to 30 seconds. This can be turned off by pressing the
button again, or by waiting for 30 seconds, or by
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.
2-6

To replace the battery in the keyless entry transmitter,
do the following:
1. Insert a thin object, such as a coin, in the slot
between the covers of the transmitter housing
near the key ring hole. Remove the bottom
by twisting the coin.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery, positive (+)
side up.3. Align the covers and snap them together.
4. Resynchronize the transmitter. See
ªResynchronizationº next.
5. Check the operation of the transmitter.
Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The transmitter
does not send the same signal twice to the receiver.
The receiver will not respond to a signal that has been
sent previously. This prevents anyone from recording
and playing back the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the lock and unlock
buttons on the transmitter at the same time for
15 seconds. The door locks should cycle to con®rm
synchronization. If the locks do not cycle, see your
dealer for service.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
·Passengers Ð especially children Ð can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not locked. So,
wear safety belts properly and lock the
doors whenever you drive.
·Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
CAUTION: (Continued)
CAUTION: (Continued)
