Remote Keyless Entry (RKE)
System
Your Remote Keyless Entry (RKE) system operates on
a radio frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may 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.
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.
At times you may notice a decrease in operating 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 is
necessary. See “Battery Replacement” later in this
section.
If you are still having trouble, see your dealer/retailer
or a qualied technician for service.

Remote Keyless Entry (RKE)
System Operation
The vehicle’s doors can be locked and unlocked from
about 3 feet (1 m) up to 65 feet (20 m) away with
the Remote Keyless Entry (RKE) transmitter.
If your vehicle has the remote start feature you can also
start your vehicle with the RKE transmitter. The RKE
transmitter, with the remote start button, provides
an increased operating range of 195 feet (60 m) away.
However, the operating range may be less while the
vehicle is running. As a result, you may need to
be closer to your vehicle to turn it off than you were
to start it.
There are other conditions which can affect the
performance of the transmitter. SeeRemote Keyless
Entry (RKE) System on page 2-4.
The following functions may be available if your vehicle
has the RKE system:
/(Remote Vehicle Start):If your vehicle has this
feature, press
/to start the engine from outside
the vehicle using the RKE transmitter. SeeRemote
Vehicle Start on page 2-8for additional information. With Remote Start and
Liftglass (Without

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/retailer. All transmitters need to be
re-coded to match the new transmitter. The lost
transmitter will no longer work after the new transmitters
are re-coded. The vehicle can have a maximum of
eight transmitters matched to it. See “Relearn Remote
Key” underDIC Operation and Displays (Using DIC
Buttons) on page 3-49orDIC Operation and Displays
(Using Trip Odometer Reset Stem) on page 3-54
for instructions on how to match RKE transmitters to
your vehicle.
Battery Replacement
Replace the battery if the REPLACE BATTERY IN
REMOTE KEY message displays in the DIC. See
“REPLACE BATTERY IN REMOTE KEY” underDIC
Warnings and Messages on page 3-56for additional
information.
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:
1. Separate the halves of the transmitter with a at,
thin object inserted into the notch on the side.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery, positive side facing down.
Replace with a CR2032 or equivalent battery.
4. Put the transmitter back together tightly.
