ok, here is the manual for your car.....
http://www.vadengmpp.com/owners-manual/ ... eville.pdfpage 2-13 has the info on resync.
Resynchronization
Pressing the transmitter button 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 instant alarm works, the transmitter needs to be
resynchronized to the receiver. To resynchronize the
remote keyless entry transmitter, press and hold both the
button with the lock symbol and the button with the
unlock symbol at the same time for about eight seconds.
You must be within range of the vehicle.
Once the transmitter has been resynchronized, the locks
will cycle (the horn may chirp and the exterior lamps
may flash depending on security feedback settings).
The system should now operate properly.
hope this helps.....who would push the buttons 250 times.....lol
