I have an 98 Lexus gs 300. I am having issues with my alarm. I am unable to start the car unless I play around with the alarm for about 5 minutes. The alarm seems to be engaged and I am unable to turn it off with the remote nor the locks on the passenger door. I would just like to disconnect the alarm so I can start the car. Can anyone help me? Any suggestions are greatly appreciated thanks. Btw it's a factory alarm.
