Remote Keyless Entry

The remote keyless entry system may
become inoperational due to a key
fob battery. If you have issues with
a key fob, replace the battery and
re-synchronize the key fob. In some
situations, the key fob may need to
be replaced and in others, a fuse may
have failed and may render both key
fobs inoperative.
Contact your dealer for more help if
a key fob does not work and it is not
because of a bad battery.
