I have a 98 LS400 and I have finally grown exhausted of hearing the incessant 'beep' to lock and 'beep beep' to unlock. Is it possible to change this on my own or do I have to take it to Lexus for a lubeless anal probing? Would love it if there were something I could disconnect. My wifes Mercedes had the feature disabled so I have to believe Lexus has the same thing....or I hope.
