Safety Tip

Lock up!  Spring and summer mean more time spent outside but don't forget to lock your front door when you're not in the house.


Plan on working in the backyard or popping over to visit a neighbor? Lock your door when you're out.


Airing out your house during spring-cleaning? Be sure to lock your windows when you close them, especially any on the main floor.


Most break-ins occur through unlocked doors or windows!
