Remote Keyless Entry (RKE)
System
SeeRadio Frequency Statement on page 8-18for
information regarding Part 15 of the Federal
Communications Commission (FCC) Rules and
RSS-210/211 of Industry and Science Canada.
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
If there is a decrease in the RKE operating range,
try this:
•Check the distance. The transmitter may be too far
from the vehicle. 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 the transmitter’s battery. See “Battery
Replacement” later in this section.
•If the transmitter is still not working correctly,
see your dealer/retailer or a qualified technician
for service.
Remote Keyless Entry (RKE)
System Operation
Vehicles with Remote Keyless Entry (RKE), transmitter
functions work up to 30 feet (9 m) away from the vehicle.
There are other conditions which can affect the
performance of the transmitter. SeeRemote Keyless
Entry (RKE) System on page 3-3.

unlock the driver door
and turn on the interior
lamps. The parking lamps
may flash and the horn

If a door is open or ajar when LOCK is pressed, the
horn sounds several times to let you know the doors did
not lock and the content theft-deterrent system is not
armed. Pressing LOCK again while the horn is sounding
or within three seconds after the horn stops sounding,
the doors lock but the content theft-deterrent system
does not arm until the opened door is closed.
Different feedback modes can be programmed through
the Driver Information Center (DIC). See “Remote
Keyless Entry Feedback” underDIC Operation and
Displays on page 4-33.
L(Panic):Press to make the horn sound and the
headlamps and taillamps flash for up to 30 seconds.
To turn them off wait for 30 seconds, or press
Lagain,
or start the vehicle.
Programming Transmitters to the
Vehicle
Only RKE transmitters programmed to the vehicle will
work. If a transmitter is lost or stolen, a replacement
can be purchased and programmed through your
dealer/retailer. When the replacement transmitter is
programmed to the vehicle, all remaining transmitters
must also be programmed. Any lost or stolen
transmitters no longer work once the new transmitter
is programmed. Each vehicle can have up to four
transmitters programmed to it.
Battery Replacement
Notice:When replacing the battery, do not touch
any of the circuitry on the transmitter. Static
from your body could damage the transmitter.
To replace the battery:
1. Separate the transmitter with a flat, thin object
inserted in the slot between the covers of the
transmitter housing.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery. Replace with a CR2032
or equivalent battery.
4. Put the transmitter back together.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however,
they do not make it impossible to steal.
Content Theft-Deterrent
If your vehicle has
the Remote Keyless
Entry (RKE) system,
the vehicle has a content
theft-deterrent alarm
system.
To activate the content theft-deterrent system:
1. Close all the doors.
2. Lock the doors with the RKE transmitter.
The security light, located on the instrument panel
cluster, will flash.
If the lock button on the RKE transmitter is pressed, but
a door is open, the horn will chirp six times. Press
the lock button again, within three seconds, and the
doors will lock. Close the open door and the system will
be activated.If a locked door is not opened using the RKE transmitter,
or by OnStar
®, the pre-alarm will go off. If the engine
is not started or unlock not pressed within 10 seconds,
the front turn signal lamps will flash for two minutes,
and the horn will sound for two minutes, then will turn off
to save the battery power.
Remember, the theft-deterrent system will not activate if
you lock the doors with a key, the manual door lock,
or power door lock switch. The system can only
be activated using the RKE transmitter, or by OnStar
®.
See the OnStar Owner’s Guide for additional
information. You should also remember that you can
start your vehicle with the correct ignition key if the alarm
has been set off.
Here is how to avoid setting off the alarm by accident:
•If you do not 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 the RKE transmitter.
Unlocking a door any other way will set off the
alarm.
If you set off the alarm by accident, you can turn off the
alarm by pressing unlock on the RKE transmitter.
The alarm will not stop if you try to unlock a door any
other way.
