Your vehicle has
one double-sided key
for the ignition, all
door locks, and the
spare tire hoist lock if
your vehicle has one.
If you ever lose your keys, your dealer will be able
to assist you with obtaining replacements.
Notice:If you ever lock your keys in your
vehicle, you may have to damage the vehicle
to get in. Be sure you have spare keys.
If you ever do get locked out of your vehicle, call
the GM Roadside Assistance Center. See
Roadside Assistance Program on page 644.Remote Keyless Entry System

cause undesired operation of the device.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following
two conditions:
1. This device may not cause interference, and
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
Changes or modications to this system by other
than an authorized service facility could void
authorization to use this equipment.
116

At times you may notice a decrease in range. This
is normal for any RKE 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 or
resynchronization is necessary. See “Battery
Replacement” and “Resynchronization”
underRemote Keyless Entry System
Operation on page 117.
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 (RKE) 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 282for more
information.
117

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 282for 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 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 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 RKE
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.
118

To replace the battery in the RKE 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.
