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.
