Which wires in the car did you use for unlock?

What model Autostart unit?

There is a position sensor wire in the same plug as the locks in the kick panel. This wire needs to receive a ground signal on unlock to allow the doors to unlock. The wire is gray

Quite literally just did one of these today(2007 sant fe)and know exactly what you're talking about.  You need to get that gray unlock detection wire, diode isolate it from your unlock wire and set for double pulse.
