This lock is easy to install by following the instructions or just google the installation video. I used it on my side door as we always forget to lock it. You need 4 AA batteries and then set a password. According to the instructions, the battery lasts a year, which is not bad. It comes with a backup key. We've been using the auto-lock feature for a few weeks now, it makes it easier for us not to worry about forgetting to relock the door.
