Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
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 2-4.
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, and the
trunk can be opened from approximately 3 feet (1 m) up
to 60 feet (18 m) away with the remote keyless entry
transmitter. If your vehicle has the remote start feature,
you can also start the vehicle’s engine with the remote
keyless entry transmitter.

If enabled through the Driver Information Center (DIC),

underDIC Vehicle Personalization on page 3-75for
additional information. If the vehicle has the content
theft-deterrent system, pressing the lock button may also
arm it. SeeContent Theft-Deterrent on page 2-18.
"(Unlock):Press the unlock button to unlock the
driver’s door. If the button is pressed again within
ve seconds, all remaining doors will unlock. The interior
lamps will come on and stay on for 20 seconds or until
the ignition is turned on. 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
remote keyless entry transmitter.See “EXT (Exterior) LIGHT DELAY” underDIC Vehicle
Personalization on page 3-75. If the vehicle has the

button on the remote keyless entry transmitter may
disarm it. SeeContent Theft-Deterrent on page 2-18.
V(Remote Trunk Release):Press and hold this

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
four transmitters matched to it.
