I remember our discussing the alarm systems for late model Lexus cars and one of the gripes is that there is no alarm mechanism for touching the car/minor impact or sensors involved. Yea, it's got the engine cutoff, window shatter, etc. but has anybody successfully added dual sensors like that guy did with the Python system while retaining the original keyfob? I just want to add this to my current Lexus alarm system. Am I dreaming or can someone do added programing?
