What happens if I change the locks but leave a spare key? I’m locked out my moms house

My mom is being an asshole, I’ve been banging on the door.. no answer.. called her least 80 times on the phone, no answer… and I just worked a 13 hour shift and I have to go back to work in seven hours… for 3-11.. possibly till 4am again…. I’m still in my uniform from work. Outside in the heat, I’m tired, everything hurts.. and what sucks. It was only my first day of work, and it’s looking like I’m going to have to miss work. I can’t work with no sleep. .. it’s currently 8:25am… I’ve been working since 3pm and clocked out for 4am.. and spent 2 hours and 30 mins traveling home…

What would happen if I changed the locks? And cut her a key? And left it on the table….

We are currently on bad terms. And she has a lot of people in her ear that doesn’t need to be in her ears, she also is suffering from vascular dementia which is making things worse
