Review: Great Quality, Easy to Install, and Convenient One-Key Option - I’m very happy with the Kwikset 660 Deadbolt. The satin nickel finish looks clean and modern, and the lock feels solid and well made. Installation was simple and straightforward, and the deadbolt operates smoothly. One of my favorite benefits is the ability to have compatible Kwikset locks keyed alike, so you can use one key instead of carrying separate keys for different doors. It’s a small convenience that makes a big difference. I also like the added Microban protection for a surface that gets touched frequently. Overall, this is a reliable, good-looking deadbolt that offers great security, convenience, and value. I would definitely recommend it.

### ⭐⭐⭐⭐⭐ Good quality and definitely recommend for safety and price!
*by D***R on October 9, 2026*

These locks are awesome! I recently bought a house that only came with one key and it only worked on two doors. I wanted to chage out all the locks and have it work with one key. I contacted a locksmith and was quoted over $300 for lock replacements and rekey. Kwikset answered my problems with their new rekey technology. So easy to use and great value for the quality and name brand. I would highly recommend Kiwkset rekey locks to anyone moving into a new home that wants to rekey the locks.
