If you still haven't found it, I suggest that you look inside the car between the seats, between the edge of the seat and the floor, near the door, in the 'pocket' of the door on the driver's side and also under the seats and near all other doors. If you have young children in car seats, check those, as well, and ask the children (if they're old enough) if they were holding the key or saw it anywhere. You didn't leave it in the ignition, did you? : )
Also, look on any 'hooks' where you may usually place your keys when you enter the house, as you may have placed it there, out of habit, when you walked back in. Also, check any tables (end table, coffee table, etc,) near the door or in any rooms you walked through before you encountered your husband. Did you stop for something from the fridge? Check there.
Check your pockets and your purse.
I hope you find the key! Please update me on your situation, if you can. Thanks!
