dei tend to not have very good range. I would recommend the one I have, its an ultrastart 1250 mad by ast, you can read up on it at ultrastarters.com. Compustar are pretty decent units also. I believe the door locks are posative triggered, so you will need a couple relays if your starter has negative outputs. You can head on over to
http://www,bulldogsecurity.com and get a vehicle tech sheet on your car that will give you wire locations and colors to simplify the install process. Even though you may not have a bulldog starter, this will work reguardless.
