Recently moved in a new apartment and I would like to change 2 locks on my door.

I'm not sure where in the states you're living, but here in Chicago IL its pretty reasonable. I can refer you to Chicago Locksmiths, I've used these guys once and they were great. Here's a link to their site. http://www.chicagolocksmiths.net/local-chicago-locksmith.php

Locksmiths usually charge more to change locks. What I would do is tell the locksmith that you want the locks to just be rekeyed if they do charge to much to change the lock. Or you can just go buy the lock itself and have them install the lock if you dont know how. My best bet is I have them rekey the locks unless the locks are no good, rusted, worn out, or you want something more secure.
