I just manually press all the buttons down...I do the front 2 when the screens go up, the back door when the curtains get closed and the sliding door when I've been for my last wee...then if up in the night for a further wee (woman of a certain age), just bob the button down when I get back...simples.
I press the lock button on the drivers door above the wing mirror switch. Dont use the alarm otherwise can't open the sliding door without setting off the alarm.
Either one of these for us, the button on the door will be the first choice once I get a single passenger seat to gain easier access to it
