Here is how to reprogram your remote yourself.

1. Turn the car to "on," but leave the radio off.
2. Press and hold the DISP button until the "settings" menu appears.
3. Press "Prev" or "Next" until Program FOB is displayed.
4. Press "DISP"
5. Press and hold "Lock" and "Unlock" at the same time until you hear a chirp. That one is done. Repeat step 5 *only* for each additional FOB. You can program up to 4 of them.
6. Press "Prev" or "Next" to get to "Exit."
7. Press "DISP"

Hope that helps.
