Matching Transmitters

Matching transmitters to your
vehicle may be necessary if you
lose or replace a transmitter. Even
if only one transmitter is being
replaced, you must rematch all of
your transmitters at the same time.
Up to four transmitters can be
matched to your vehicle.
See your dealer to purchase a new
transmitter and to have transmit-
ters matched to your vehicle.
