When using these, you really need to use longer screws and anchor into something more substantial than the typical 3/4" wood door frame.
Behind every factory door frame in a residential home wall are typically two wall studs together (king and cripple). You want to use three 3 inch or longer wood screws and anchor into those studs through the 3 vertically aligned holes in the lock. The 4th hole that is closest to the room and because that hole will be missing the wall studs, you can use the supplied shorter screw to get started. Pre-drill all holes and wax the screws or at least use some bar or dish soap on the screws to make them go in easier.
PS: While you are at it, remove a screw or two from each hinge closest to the center of the frame and install some longer screws there as well. Over the years, I have seen enough vandalized doors to know the weaknesses.
PPS: These work only on in-swing doors that are quite typical with additional exterior storm doors... If your door swings out, like some front housing doors do, these will be of no use.
