Winter storage - how do you lock doors, without battery on?

[G-96592]

I need to put my car (2022 Genesis G70) away for winter storage. I disconnected the battery but now I cannot lock the doors. How do I lock the doors without the battery on? Reason for disconnecting: save the battery usage during the 6 months in winter storage.

There should be a physical key or you can open the trunk lock the doors then disconnect the bat.
