  • 665 Double Cylinder Deadbolt in Antique Brass is rated 4.2857 out of 5 by 7.
    Rated 4 out of 5 by from Just what I needed. After 30 years of daily service one of two Kwikset Double Cylinder Deadbolt Locks failed. The lock cylinder came out with the key. Thirty years is pretty impressive; so I decided to hunt up two more keyed alike in Antique brass to replace the original "Bright Brass" locks. The doors required very minor trimming with a chisel for a perfect fit and because my doors were 1 3/4" thick it took a little fiddling to get the inner mechanism and bolts to line up. It would have been helpful to have had a third hand.The lock operates smoothly and the bolt extends adequately into the door jam.For my situation the Kwikset locks were a good solution and great value.I was happy to find theses locks here and in a finish that compliments the old door and hardware.

    Rated 2 out of 5 by from first issue in 40 some years What happened Kwikset, you changed the design? bigger cylinder screws with the same cylinder hole as old which is not the right size. The screw won't fit in the cylinder. The nice people at Lowes looked at it to and thought either the wrong screws or the wrong cylinder went into the package.I am not abandoning Kwitset but this was a surprise.Open the box before you purchase and look and see if the screws go through the cylinder before you buy.
