Resynchronization
Pressing the remote keyless entry transmitter buttons
numerous times (approximately 250 times) out of the
vehicle's operating range may cause the transmitter not
to work. Replacing the battery and pressing the
transmitter buttons out of range will also cause the
transmitter not to work. If only the fuel door button
works, the transmitter needs to be resynchronized to
the receiver. Do this by pressing and holding both the
lock and unlock buttons on the transmitter for about
eight seconds. You must be within range of the vehicle.
Once the transmitter has been resynchronized, the horn
will sound and the exterior lamps will flash once. The
system should now operate properly. See your dealer for
service if your transmitter doesn't work properly.
