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.

greater than 8 mph (13 km/h). This is the mode
that is pre-programmed in the factory for manual
transmission vehicles.
