Maybe you should have a good look at the regulations. Opening and closing a quick access panel is not a "maintenance" action and it does not invalidate the CRS.
Maybe look up the meaning of "servicing". Servicing is generally considered not maintenance.
Is the CRS invalidated by any of the following???:
Aircraft fuelled.......access panel opened/closed (fuel added).
Water uplifted..........access panel opened/closed (water added).
Toilet serviced.........access panel opened/closed (get the picture).
