Remote Keyless Entry (RKE)
System Operation
The vehicle’s doors can be locked and unlocked,
and the trunk can be opened from about 3 feet
(1 m) up to 60 feet (18 m) away with the Remote
Keyless Entry (RKE) transmitter. If your vehicle
has the remote start feature, you can also start the
vehicle’s engine with the RKE transmitter.The following functions may be available with your
vehicle’s RKE system:/(Remote Vehicle Start):If your vehicle has
this feature, the engine may be started from
outside the vehicle using the RKE transmitter.
See “Remote Vehicle Start” at the end of
this section for more detailed information.
Q(Lock):Press the lock button to lock all the
doors. If enabled through the Driver Information
Center (DIC), the parking lamps may ash once to
indicate locking has occurred, or the horn may
chirp when the lock button is pressed again within
ve seconds from the previous press of the
lock button. See “FOB LOCK FEEDBACK” under
DIC Vehicle Personalization on page 229for
additional information. If the vehicle has the

If enabled through the DIC, the parking lamps can
be programmed to come on for a set amount of
time when the vehicle is unlocked using the
RKE transmitter. See “EXT (Exterior) LIGHT
DELAY” underDIC Vehicle Personalization on
page 229. If the vehicle has the content
theft-deterrent system, pressing the unlock button
on the RKE transmitter may disarm it. See
Content Theft-Deterrent on page 104.
V(Remote Trunk Release):Press and hold
this button for about one second to release
the trunk lid. The transaxle must be in PARK (P)

and the horn will sound repeatedly for two minutes.
The alarm will turn off when the ignition is moved to
RUN or the alarm button is pressed again.
Matching Transmitter(s) to Your
Vehicle
Each RKE 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 four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in the RKE
transmitter should last about four years.
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.
The KEY FOB BATT LOW message in the
vehicle’s DIC will display if the RKE transmitter
battery is low.
91

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 RKE transmitter, do
the following:
1. Insert a at object, with a thin edge, into the
notch located below the panic alarm button,
and separate the bottom half from the top half
of the transmitter.2. Remove the old battery. Do not use a metal
object to do this.
3. Slide the new battery into the transmitter with
the positive (+) side of the battery facing up.
Use one three-volt, CR2032 battery, or
equivalent type.
4. Snap the front and the back of the transmitter
together. Make sure the cover is on tight, so
water will not get inside the transmitter.
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. When the remote start
system is active, the climate control system will
heat or cool the inside of the vehicle based on the
outside temperature. The rear window defogger
will be turned on by the climate control system
when it is heating the inside of the vehicle. Normal
operation of the system will return after the key
is turned to the RUN position.
Laws in some communities may restrict the use of
remote starters. For example, some laws may
require a person using 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 remote start feature provides two separate
starts per ignition cycle, each with 10 minutes
of engine running time.
The remote vehicle start feature needs to be reset
after your vehicle’s engine is started two times
using the transmitter’s remote start button.
The remote start system is reset by inserting the
vehicle’s key into the ignition switch and turning it
to RUN. SeeIgnition Positions on page 109for
information regarding the ignition positions on your
vehicle.
The RKE transmitter with the remote start button
provides an increased range of operation. You can
start your vehicle from an average range of about
492 feet (150 m) away. However the range may be
less while the vehicle is running, and 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 (RKE) System on page 89for
additional information.

ash. The vehicle’s doors will lock.
3. When the vehicle’s engine starts, the parking
lamps will turn on and remain on while the
engine is running.
The engine will shut off automatically after
10 minutes, unless a time extension has been
done or the vehicle’s key is inserted into
the ignition switch and turned to RUN.
If you enter the vehicle after a remote start,
and the engine is still running, insert the
key into the ignition switch and turn it to RUN
to drive the vehicle.4. To manually shut off a remote start, do any of
the following. The parking lamps will turn off:

one remote start procedure has been done,
since last driving the vehicle, or resetting the
remote start system, the engine may be started
again remotely following the remote start
procedure a second time
If the remote start procedure is used again before
the rst 10 minute time frame has ended, the
rst 10 minutes will immediately expire and
the second 10 minute time frame will start.
