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. 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.
Battery Replacement
Under normal use, the battery in the RKE transmitter
should last about two years.
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.To replace the battery:
1. Insert a coin, or similar object, in the slot between
the covers of the transmitter housing. Gently pry
the transmitter apart.
2. Remove and replace the battery with a
three-volt CR2032 or equivalent battery.
3. Align the covers and snap them together.
4. Check the operation of the transmitter.
