### ⭐⭐⭐⭐⭐ Reliable lock with great features

This thing is incredible. I appreciate the Satin Nickel finish which looks modern and clean. The SmartKey Security makes rekeying simple, and Microban protection adds an extra layer of security.

### ⭐⭐⭐⭐⭐ Simple, solid deadbolt. great value and easy swap for rentals
*by B***C on December 31, 2025*

I installed this Kwikset 660 deadbolt a few weeks ago to replace an older keypad deadbolt, and so far it’s been a solid, no-frills option that does what it’s supposed to do. It has a slightly flimsy cover, but overall, right for the price. Installation was straightforward and quick. Everything lined up properly, and it came with two keys, which was a plus. The lock operates smoothly and hasn’t given me any issues since installing it. The components do feel fairly lightweight, which matches the price point. It doesn’t have a heavy or premium feel, but nothing about it feels flimsy in actual use either. Once installed, it feels secure and functions reliably. One helpful tip for installation: if the knob direction doesn’t match your door setup, you can flip the entire deadbolt assembly upside down instead of trying to force it. That made the install much easier. Overall, this is a good choice if you want a simple, affordable deadbolt that’s easy to install and gets the job done. If you’re looking for a heavier, more premium feel, you may want to spend more, but for basic home use, this one is perfectly fine.
