Bought the armor pro lock sidelight kit. I followed the directions in the installation videos and that really helped. At first I thought I would have to chisel some of my door frame off because I didn't have a lot of clearance where the strike plate goes. But installing the hinge guards first with 3.5 inch screws pulled the door enough to create clearance on the lock side. Everything went in pretty easy. Only complaint I have are the screws that are provided had a square in the head which kept trying to strip because the driver bit is too soft and started becoming round. Luckily I had just made a trip to the hardware store and picked up a box of 3.5 screws with star torx heads and used those as they were stronger and didn't slip on me. Those type of screws should be provided in the kits, not those square head ones that suck. Thank you for the kit!
