Security Alarm Problems in 92 - 00 Lexus SC300 / SC400 Posted June 3, 2009 Do you have an aftermarket alarm or anything else addded to the car? I have all original equipment. I did change the battery on the key fob and that seemed to help I'm thinking of hooking the horn back up Could all of this mess be as simple as changing the remote's battery? DON Did you ever solve the alarm issue ?
