2005 GMC SIERRA 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 “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
If you are still having trouble, see your dealer or a
qualied 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):Press this
button once to 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. See “Lock Feedback” and
“Unlock Feedback” underDIC Vehicle Customization on
page 3-54for more information.

Q(Lock):Press this button once to lock all of the
doors. Pressing lock again within three seconds
may cause the horn to chirp for lock conrmation. You
can choose different feedback options for each press
of the lock button. See “Lock Feedback” and “Unlock
Feedback” underDIC Vehicle Customization on
page 3-54for more information.
L(Panic):Press this button to sound the horn and
ash the headlamps and taillamps for up to 30 seconds.
Panic can be turned off by pressing the button again,
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 will not
work at the normal range in any location. If you have
to get close to your vehicle before the transmitter works,
it is 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.
2-5

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
“Resynchronization” following this information.
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 conrm
synchronization. If the locks do not cycle, see your
dealer for service.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — 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.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.To lock and unlock your vehicle, do one of the following:
You can use the keyless entry system,
use your key, or
lock the door from the
inside by sliding the
manual lock lever
rearward. To unlock the
door, slide the manual
lock lever forward.

Operating the power locks may interact with the
theft-deterrent system (if equipped). SeeContent
Theft-Deterrent on page 2-14.
Delayed Locking
When locking the doors with the power lock switch or
the keyless entry transmitter and a door or the liftgate
(if equipped) is open, the delayed locking feature
will delay locking the doors until ve seconds after the
last door is closed. You will hear three chimes to
signal that the delayed locking feature is in use.
Pressing the power lock switch or the lock button on the
keyless entry transmitter twice will override the delayed
locking feature and immediately lock all the doors.
You can turn the delayed locking feature off or back on
again by doing the following:
1. Press and hold the power door lock switch in the
lock position.
2. Press unlock twice on the remote keyless entry
transmitter.
This feature will not operate if the key is in the ignition.

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 on the cluster
will ash as you open
the door (if your ignition is
off), to let you know
that you are activating the
system.
This message 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 ash. If you are using the
remote keyless entry transmitter, the door does not
need to be open.
