Should teenagers be able to have locks on their doors?

As

So my family built my house (not literally but you know what I mean) without locks on the doors. I was 8 when I moved in so it wasn’t a problem. Now that I’m a teenager I’ve been thinking about a lock on my bedroom door. I don’t think I need it but I just wondered what my parents would say and also what the people of CC would say. Do you think teens should be allowed locks on their bedroom doors or not? I don’t really have an opinion on it cause it gives the kid a little privacy but they could also be doing illegal stuff behind the door and the parents won’t be able to get in. Anyways voice your opinions in the comments.
