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

Remote Keyless Entry System
Operation
If your vehicle has this feature, the vehicle’s doors can be
locked and unlocked, and the trunk can be unlocked from
about 3 feet (1 m) up to 60 feet (18 m) away with the
remote keyless entry transmitter.
If you notice a decrease in the operating range of the
transmitter, seeRemote Keyless Entry System on
page 2-3for information regarding conditions which
may affect the transmitter’s performance.
The following functions are
available with the remote
keyless entry system.
2-4
Matching Transmitter(s) to
Your Vehicle
Each remote keyless entry transmitter is uniquely coded
to prevent another transmitter from unlocking the
vehicle. If a transmitter is lost or stolen, a replacement
can be purchased through your GM dealer. Remember
to bring any additional transmitters with you when
you go to your dealer. The vehicle can have a maximum
of four transmitters matched to it.
Battery Replacement
Under normal use, the battery in the remote keyless
entry transmitter should last about four 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. The
KEY FOB BATT LOW message in the vehicle’s DIC will
display, if the remote keyless entry transmitter battery
is low.
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 do the following:
1. Insert a at object with a thin edge into the notch,
located below the Vehicle Locator/Panic Alarm
button, and pry the front and back apart.
2. Remove the old battery, but 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 a type
CR2032 battery, or equivalent type.
4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.

PASS-Key
®III+ uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
PASS-Key®III+ Operation
Your vehicle is equipped with PASS-Key®III+
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®III+ is a passive
theft-deterrent system. This means you do not have to
do anything special to arm or disarm the system. It
works when you insert or remove the key from
the ignition.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.When trying to start the vehicle if the engine does not
start and the security light on the instrument panel
cluster comes on, the key may have a damaged
transponder. Turn the ignition off and try again.
If the engine still does not start, and the key appears to be
not damaged, try another ignition key. At this time, you
may also want to check the fuse, seeFuses and Circuit
Breakers on page 5-98. If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the rst key may be faulty. See your
dealer who can service the PASS-Key
®III+ to have a
new key made. In an emergency, contact Roadside
Assistance. SeeRoadside Assistance Program on
page 7-6.
It is possible for the PASS-Key
®III+ decoder to “learn”
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle. The
following procedure is for programming additional keys
only. If all the currently programmed keys are lost or do
not operate, you must see your dealer or a locksmith who
can service PASS-Key
®III+ to have keys made and
programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the system.
