Bests & Worsts Reviews from Amazon

Super easy to install looks nice and really secure. As a police officer with training in CEPTED and other crime prevention practices I can say a secondary lock such as this works well at preventing forced door entries. Also, this will keep your little ones from opening the front door and sneaking out into the street. My suggestion for install. Figure out where it fits best on your door frame by holding it up and and testing the door does not make contact with the lock when opening and closing. Then draw around the screw plate leaving the mark on the frame. Use a chisel and hammer and take the wood in that space out by lightly taping the wood out with chisel and hammer. Then put the screw plate in that chisled opening. Screw in with 3 inch screws, buy them on your own. (3 inch adds extra security). Cover with wood filler, sand and paint. It will look perfect when done. (Yes I still have to sand and paint for the final finish)
