My key is kept in a key lock box used to hold a key realtors use on for sale homes.
There’s a 4 digit code used to open it.
It just sits on our head board.
She grabs a key to take with her when we go on long trips.
Once we went somewhere and she forgot the key. We were going to make love (she was in the mood) and learned she left the key here.
She got satisfied and slept well. I just slept. Lol
