I had it on my Impreza, Vr6 and Ep82. Good investment if you want to keep your car. Basically get in car shut door start engine, type in pin no which can be minimum of 2 digits on scratchpad, drive off. Booklets you get are a bit crap. Forget calling clifford. Go to place where alarm was fitted, ask them to show you how to use it and change the pin number. Get home change your pin to a different one so the guys at garage dont know and away you go. Sorry for the waffle, I hope this helps.
