jimbosin,
I do not know if what I posted awhile back applies to your UK 1995 version. I know if this car was sold in the States it would not be OBDII compliant for the model year and thus would make me think that many other things were different, including the alarm system. Kia introduced the sporty to the US in 1998.
However on the chance that I am wrong, have a look at the link below. If you haven't done so, I would do a search in this forum on RKE, Alarm, Immobiliser and you get the point. Now that I am thinking about it, are you sure the immobiliser system was from Kia? I didn't think they were factory installing them (or dealer) back then. Another one I could be mistaken about.

Good Luck...
