  • 660 Single Cylinder Deadbolt in Venetian Bronze is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Deadbolt locks that are easy to install If you ever need to change your Deadbolt & key the Kwikset components are almost universal. This means that one can usually change out the cylinder and use all the old hardware and latch, the part that moves in & out. The Kwikset brand is especially handy for landlords that need to change locks quickly & often. Another bonus Kwikset give you is the fact that repair parts are often in stock at your local hardware, and the keys somehow duplicate easily & correctly. I can't tell you how many times I've had a key made for a different brand and it didn't work. Kwikset duplicate keys always work the first time for some reason. A little security tip; if you use a foot or so long piece of plumbers strap (metal tape w/holes) screwed along the wooden door frame (behind the molding) to reinforce the hole for the latch - it makes it very difficult to kick in the door. If you need keyed alike locks, the key codes are on the package. So you can match up as many keyed alike locks as needed.
