Replacement of the battery will not
cause the remote transmitter to
become deprogrammed from your
vehicle. The remote transmitter
should operate normally after
battery replacement.
Replacing lost transmitters
If a remote transmitter has been
lost and you would like to remove it
from the vehicle's memory, or you
would like to purchase additional
transmitters for your vehicle (up to
four may be programmed into
memory), take all your vehicle's
remote transmitters either to your
dealer or perform the programming
procedure yourself. It will be
necessary to reprogram all the
remote transmitters to your vehicle
at the same time while performing
this service.
Programming procedure
1. Close all doors and fasten the
seat belt to ensure conflicting
chimes do not sound during
programming.
