If he follows through with that threat, what recourse will I have if I find myself locked out of my apartment and all my things gone?

I'm currently withholding rent because he refuses to fix the multiple problems with the apartment. Long story short, I’m waiting to go to court but he thinks he doesn't have to do that. He told me I have a week to move or he's going to have the police throw me out. Obviously, he can’t do that because that's not how it works. The other part of his threat is what I’m worried about. He said that he is moving someone into my apartment on the first. If I’m not out, he will change the locks and throw away all my things. The thing is, I think he is stupid enough to do it and I can’t take the day off from work to stop him.
