Local police departments have security tips on their websites to help you protect your home and loved ones. However, if you leave your windows or door open none of these tips will help.

Keep your door locked, even if you are just working in the yard.

Install window locks so they open no more than 4". Never leave them open when you leave home.

Be wary of anyone approaching your door or ringing your bell. Keep a locked door between you and the stranger.
