We installed the Kwikset Pismo Round Keyed Entry Smartkey Venetian Bronze knob on our bedroom door. We had an older knob installed and I was ready to upgrade to one more updated looking and one that was, well more appealing to the eye. We leave town a lot so I  like to lock our bedroom door. 
The Pismo door knob was extremely easy to install, it came with simple and direct instructions. It fit our door perfectly. All we had to do was remove our old knob and hardware and replace it with the beautiful Pismo Knob and included hardware.  It took less than 20 minutes all together. 
I am wanting an electronic lock for our front door and noticed this brand also carries those. I will definitely be researching them to see if they are worth purchasing.
