Tenant changed locks - 24 hr notice to change back?

[Jessica Wood]

Our TFH (tenant from hell) has received her 7 days to vacate. When those expire we will be filing a forcible entry and detainer. In the meantime, the peach has switched out the doorknob lock and we can’t enter the unit in case of an emergency. Our lawyer said if we switch out the lock, we have to leave her a key until her 7 days expires. But, I need to be able to enter in case of an emergency. If I am going to remove her doorknob that I don’t have keys to, and put a plain ole doorknob there, do I need to post a 24 hour notice to enter the premises? Or do I have a legal right to un-alter the premises? She has also added a lock right inside the door that I’d like to rip off. And on the bedroom door as well. She is the worst. Any insight? I don’t want to bug our lawyer on Labor Day.
