Remote Keyless Entry (RKE)
System
If the vehicle has a 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 modifications 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 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 (RKE) System
Operation on page 105.
•If you are still having trouble, see your
dealer/retailer or a qualified technician
for service.

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
dealer/retailer. Remember to bring any remaining
transmitters with you when you go to your
dealer/retailer. When the dealer/retailer matches
the replacement transmitter to your vehicle,
any remaining transmitters must also be matched.
Once your dealer/retailer 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.
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 seven seconds. The door locks should cycle
to confirm synchronization. If the locks do not
cycle, see your dealer/retailer for service.
Battery Replacement
Under normal use, the battery in your remote
keyless entry transmitter should last about
four years.
You can tell the battery is weak if the transmitter
won’t work at the normal range in any location.
If you have to get close to your vehicle before the
transmitter works, it’s 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.
