I am a scuba diver and have not yet found a dry container that will be guaranteed by the manufacturer to withstand the pressures of deep diving below 20 metres depth so my solution with a 2019 Forester is to use a portable key storage safe clipped to the chain anchors associated with the towbar kit (see the type of device I mean at Sandleford 150 x 60 x 45mm Portable Key Storage Safe).
