It happened to me as well - but on a RX450h (I guess it is not fixed). Ten days at the airport - flat "as a pancake".
The service guy at Lexus told me straight up that I couldn't expect to have the car standing tat long without removing the fuses. He politely showed me how to remove cover, open fusebox and locate/remove the white fuse. Then coming home, just open the car manually with the key, dig in under the bonnet, reverse the procedure, put everything in place and drive off.
I thought that we has joking.
Grrr...
