2007 GMC YUKON XL lock

At times you may notice a decrease in operating
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 113.
If you are still having trouble, see your dealer or
a qualied technician for service.
Remote Keyless Entry System
Operation
The vehicle’s doors can be locked and unlocked
from about 3 feet (1 m) up to 65 feet (20 m)
away with the Remote Keyless Entry (RKE)
transmitter.
If your vehicle has the remote start feature you can
also start your vehicle with the RKE transmitter.
The RKE transmitter, with the remote start button,
provides an increased operating range of 195 feet
(60 m) away. However, the operating range may be
less while the vehicle is running. As a result, you
may need to be closer to your vehicle to turn it off
than you were to start it.
There are other conditions which can affect the
performance of the transmitter. SeeRemote
Keyless Entry System on page 112.

The following functions may be available if your
vehicle has the remote keyless entry system:

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
GM dealer. Remember to bring any additional
transmitters so they can also be re-coded to match
the new transmitter. Once your dealer has
coded the new transmitter, the lost transmitter will
not unlock your vehicle. The vehicle can have
a maximum of eight transmitters matched to it. See
“Relearn Remote Key” underDIC Operation and
Displays (With DIC Buttons) on page 244or
DIC Operation and Displays (Without DIC Buttons)
on page 251for instructions on how to match
RKE transmitters to your vehicle.

3. Slide the new battery into the transmitter with
the positive side of the battery facing down.
Use a type CR2032 battery, or equivalent
type. Make sure the cover is on tightly,
so water will not get in.
4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine
from outside of the vehicle. It may also start up
the vehicle’s heating or air conditioning systems
and rear window defogger. Normal operation of the
system will return after the key is turned to the
RUN position.
If your vehicle has an automatic climate control
system, during remote start, the climate control
system will default to a heating mode during colder
outside temperatures and a cooling mode during
warmer outside temperatures. If your vehicle
does not have an automatic climate controlsystem, during remote start the climate control
system will turn on at the setting the vehicle was
set to when the vehicle was last turned off.
Laws in some communities may restrict the use of
remote starters. For example, some laws may
require a person using the remote start to have the
vehicle in view when doing so. Check local
regulations for any requirements on remote starting
of vehicles.
Do not use the remote start feature if your vehicle
is low on fuel. Your vehicle may run out of fuel.
The keyless entry transmitter with the remote start
button, provides an increased range of operation.
However, the range may be less while the
vehicle is running. As a result, you may need to
be closer to your vehicle to turn it off, than
you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry System on page 112for additional
information.
/(Remote Start):Press and release the lock
button and then press and hold the remote
start button to start the vehicle.
117

To start the vehicle using the remote start feature,
do the following:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock button,
then immediately press and hold the
transmitter’s remote start button until the turn
signal lights ash. If you can not see the
vehicle’s lights, press and hold the remote start
button for at least four seconds. The vehicle’s
doors will lock. Pressing the remote start button
again after the vehicle has started will turn off
the ignition.
When the vehicle starts, the parking lamps will
turn on and remain on while the vehicle is
running.
3. If it is your rst remote start since last driving,
repeat these steps while the engine is still
running for a 10 minute time extension.
Remote start can be extended one time.
When you enter the vehicle during a remote start,
and the engine is still running, turn the key to
the RUN position to drive the vehicle.
If the vehicle is left running it will automatically
shut off after 10 minutes unless a time extension
has been done.To manually shut off a remote start, do any of the
following:
Aim the remote keyless entry transmitter at
the vehicle and press the remote start
button until the parking lamps turn off.
Turn on the hazards warning ashers.
Turn the ignition switch on and then off.
The vehicle can be remote started two separate
times between driving sequences. The engine will
run for 10 minutes after each remote start.
Or, you can extend the engine run time by another
10 minutes within the rst 10 minute remote
start time frame, and before the engine stops.
For example, if the lock button and then the remote
start buttons are pressed again after the vehicle has
been running for ve minutes, 10 minutes are
added, allowing the engine to run for 15 minutes.
The additional ten minutes are considered a
second remote vehicle start.
Once two remote starts, or a single remote start
with one time extension has been done, the
vehicle must be started with the key.
After the key is removed from the ignition, the
vehicle can be remote started again.
118

The vehicle cannot be remote started if the key is
in the ignition, the hood is not closed, or if
there is an emission control system malfunction.
Also, the engine will turn off during a remote
vehicle start if the coolant temperature gets too
high or if the oil pressure gets low.
Vehicles that have the remote vehicle start feature
are shipped from the factory with the remote
vehicle start system enabled. The system may be
enabled or disabled through the DIC. See
“REMOTE START” underDIC Vehicle
Customization (With DIC Buttons) on page 264
for additional information.Remote Start Ready
If your vehicle does not have the remote vehicle
start feature, it may have the remote start
ready feature. This feature allows your dealer to
add the manufacturer’s remote vehicle start
feature.
If your vehicle has the remote start ready feature,
your RKE transmitter will have extended range
that will allow you to lock or unlock your vehicle
from approximately 197 feet (60 m) away.
See your dealer if you would like to add the
manufacturer’s remote vehicle start feature to your
vehicle.
