I seem to be having trouble with the .jpg attachment below. It will help identify the terminals on the 20 pin under hood diagnostic connect. But the following is the proceedure to program the transmitter, if it is compatible with your vehicle.
Turn ignition switch on, then jumper terminals 5 and 6 on the under hood diagnostic connector. Push and hold the LOCK button on the transmitter, and the turn signals should flash. If you have a second transmitter to program push the LOCK button at this time and the signals will flash. Then remove the jumper and turn the ignition off. You can only program 2 transmitters per vehicle. Hope this helps, and if you can not open the attachment just drop me a line and I will email it to you.
This proceedure was used on a 2005 U.S. Sorento. The 20 pin connector is located on the left side of the Kia and at the right lower corner of the power distribution box and it is the same height as the box. Flip up the cover of the 20 pin connector and the configuration will match the picture that was attached in the previous post.
I would rather do it than worry about driving it in and waiting for someone to come out. Knowing my luck they would find something wrong (even if it was fine) and I'd be talked into getting it "fixed" Bah.
