if you are talking to lawyers about the keys, mention it to him that she took all the possessions, I'm sure you own them jointly so what gave her the right to decide she can have them all?
Yes you have to mention it and it has to be noted so that you don't lose out on anything. If you just sit there and take it without making a peep, it will be seen as you accepting what she did and you were ok with it.
Are you afraid to make noise? Are you afraid to rock the boat?
If so, I'll ask you WHY?
As for the house and refurbishing it, etc. Do what you WANT to do and start getting used to the feeling of leading your life in the direction you want to go instead of asking for permission - it's your home, just do it.
