i programmed mine with the instructions from, it told me to insert the key, and than turn it from the off position to run position 4 times within six seconds, than u push the lock button on the remote u wish to program. i was pretty sceptical it'd work too...but it did... here are their exact directions, what i just told u is what worked when i did it

1. Turn the ignition from OFF to RUN 4 times within 6 seconds. 2. Turn the ignition OFF. The LED in the clock/trip computer will light up continuously

to confirm programming mode. 3. Within 20 seconds, press any button on the first keyless remote. The LED in the

clock will flash 4 times to confirm programming. 4. Within 20 seconds, press any button on second keyless remote. 5. Turn the ignition to RUN. The LED will turn off to indicate end of programming mode.
