If you are concerned about the security of your house, then the first thing to do is make sure your doors and windows aren't easy targets. If your doors or windows don't have strong enough locks, then it may be possible for a burglar to easily get into your house. To determine whether or not you should have your locks changed, consider the following:
Do your doors have movement?
Shut and lock your doors. Pull on the doorknob and see if they give and have a bit of movement. If the doors do wiggle then there is the chance that a burglar will be able to fit certain tools between the door and the frame in order to get the door to open. In this case, you may need a new door, a protective plate, a new frame, and/or a new doorknob set.
Do all outside doors have deadbolts?
No matter what type of locks you have on the doors that lead to the outside, if they don't have deadbolts then you are taking a gamble. Burglars can get very good at picking locks or even breaking through them using other methods. However, a deadbolt is a very difficult, if not impossible, lock for them to get through.
Do your windows move when they are locked?
Lock your windows and see if you can move them at all. You can try shifting the window from both the bottom and top part of the frame to see if there is any movement. If there is, then there is the chance that a burglar will be able to work the window open even when you have it locked.
Does your sliding glass door move?
Sliding glass doors are often very big targets for burglars. This is due to the fact that there are several methods they can use to get them open if the doors don't have a very good lock system in place. A sliding glass door may need a good lock in the middle, as well as ones on the top and bottom, to truly secure it from being an easy target.
