You are probably being paranoid about safety. The chances of someone breaking into your house through locked doors violating building security in a decent neighborhood are very small. You are far more likely to die in a car crash. That said, if you want extra security in your house you could use deadbolt door and window locks. Those are very hard to get through. You could also buy a gun. Get a dog if you will be a responsible pet owner.
