Just acquired a GS400 1998 Model. It has neo been put into use. However, I experienced a problem recently when I tried to start the car as the alarm sounded and head lamp flashes. I had to remove the battery terminal as all effort to deactivate the alarm failed using the the remote control. Could any one out there profer a solution as I am new to this and the manual is not total helpful. Regards Oladimeji Suberu
