Kwikset 660 Single Cylinder Deadbolt with SmartKey Security, Matte Black

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.

Lock worked great, re-key is ingenious and the process is very easy. I recommend this lock.

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.

As a professional handyman, I've installed a dozen or so of these for various customers. They install quickly, and the Smartkey re-keying capability is especially a big value add for customers with rental units. Strongly recommended, and I am a repeat customer.

Not bad, a little difficult to put in but thats just me, I'm not experienced in this. Very shiny. Can't complain

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.

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

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!

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