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 your 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 thin 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.
