Purchased and installed unit into door. After installation keys that came with unit worked on door handle lock but would not operate dead bolt lock for exterior. Currently requesting assistance from Kwikset for solution. Retuning unit would be upsetting and timely. Will update on assistance I receive from Kwikset. I currently have questions about Kwiksets Quality Control if it allows a unit to be packaged with a non working lock. At this time I could NOT recommend this unit, time will tell.
