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.
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.
See your dealer to match transmitters to another
vehicle.

Battery Replacement
Under normal use, the battery in your remote
keyless entry transmitter should last about
three 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.
1. Insert a flat object, such as a coin, into the
slot on the side of the transmitter and twist it
to separate the halves.
