I installed this lock set in my garage entry door so I could get rid of my hidden key. It was very simple to install and the directions were straightforward. I had one little misstep... when the directions tell you to check the latch, make sure you’re on the inside of the door! I had to step outside the opening to adjust the latch, and proceeded to “check it” and locked myself out of the house! Backup keys and code not set yet. (The latch key can be turned to open all the time or lock all the time.... it was in the lock position). After climbing through a second story window to get back inside, and programming the code, all is well. My husband got a good laugh out of it.
