KIAYACI Double Door Lock Set

Let me start by saying that I am a carpenter/handyman by trade. This was for my own personal front door as it looked like a great deal and looked adequate at first glance and install. After installing the door handle and lock, the automated deadbolt would not physically turn the deadbolt once installed. At first I assumed something was too tight or misinstalled and I took it all apart and then re assembled it, checking ti all very carefully as I re-installed it the second time. And again, the lock would not operate correctly. Very angrily, I uninstalled it and reinstalled my DEFIANT automated lock which worked fine but didn't match my door handle. So I called Amazon, they sent a replacement and the exact same thing occurred again. These products are cheap and not worth your trouble. If you were just buying the door handle. it would be fine. But leave the automated stuff to companies that are Reputable. Maybe I just got a couple of lemons but both my experiences were bad. Hope this helps someone choose.
