Product Reviews

Rated 3 out of 5 by from Poor design requires special tool I purchased a few of these Kwikset knob-sets. When I began to install the first one I saw that the keyhole was at the top of the knob. Every lock, and every picture of a lock that I've ever seen, shows the keyhole starting at the the bottom of the lock face (the flat edge of the key, facing down). . . . I read the instructions and this CAN be changed but it requires a special tool. Kwikset offered to send me this tool for free, but when I again looked at the instructions, I realized it was going to take considerable time to go through all the steps. I was going to be changing ALL the knob-sets out in my home and I estimated it was more trouble than it was worth. . . . I sent back the knob-sets back to and they did a smooth and easy return and refund. . . . After more investigation I spent a few more bucks and then ordered Schlage knob-sets that allow the keyhole postion to be easily changed regardless of whether the knob is on the right or left side of the door. Some people may WANT the keyhole on the top and that's possible too! Their installation was simple and fast. . . . No more Kwikset products for me.

Rated 4 out of 5 by from Excellent exterior; lighter interior I ordered this knobset in the lifetime polished brass. It installed easily and the quality of the exterior brass is excellent. My only disappointment was with the quality of the materials used on the interior parts. These are a lighter weight brass and don't look or feel as substantial as the exterior.

Rated 4 out of 5 by from Works Great! This product was easy to install and works great. It was really nice not to have to get our other locks re-keyed, but we could set this lock to work with the existing key. We are very satisfied.
