Difficult to setup and deadbolt does not work! I purchased this to match other knobs but I’m extremely disappointed. First of all, I was unable to remove the knob - a key step in installing the provided screws. I also had a professional try and I had to use different screws in the end. 

Next, I got the deadbolt installed following the instructions. However, after removing the key it not longer works. WD-40 helps, but it still only turns with the key in it, rendering the unit useless. 

I’ll be uninstalling it and returning it this weekend.
