I have a 1992 SC that I just bought 2 weeks ago and the keypad for the alarm sys, power locks and trunk opener took a **** on me. I had the keypad checked & a new battery installed and it still doesn't work. Does anyone know who the manufacturer is on the factory alarm systems and how do I find out??? I looked on the siren itself to try to find a name and there was nothing and the guy who I bought her from had no papers on it. If no one knows then I will have to pay this alarm guy to tear my dash out, with no guarauntee he'll find out, Please help. Email me: zena058@msn.com Thanks, Regina
