Easy install and great product
Super easy instillation, great pricing, feel safe with the easy of using the deadbolt. I love the square shape and I feel like this product will last a very long time. You can adjust the key settings to match any kwikset key you have and it is a HUGE plus to have everything match. Highly recommend, great product and easy to install.

Okay
Seems okay. Not made anywhere near so heavily as the 34-year-old lock it replaced.

Very easy and nice looking
It was the easiest thing I’ve ever done was to exchange my old non latching dead bolt for this new one ,took about 5 minutes , and looks very nice now I’ll have to get the matching door knob

Very Disappointed!
I ordered two of these but one has a defective bolt. It only travels half way and stops. I don't want to play with it. PROBLEM: My return window closed two days ago. I'll still try to get a return, but if I don't, I'm stuck. Brand new lock that won't work out of the box!

A good purchase
Perfect replacement for existing Kwikset deadbolt. The Smartkey feature allowed me to use only 1 key for all four locks in my home.
