Review: Easy to Install - I love how easy it is to install – it took me just a few minutes to set it up without any hassle. The unkeyed design is perfect for situations where keyless entry is preferred, providing convenient access without the need for keys. The build quality is top-notch, as expected from Kwikset. The lock feels solid and durable, giving me peace of mind knowing that my home is secure. One thing to note is that it's always locked from the outside, so you'll need to remember to keep it unlocked when you're not at home to avoid getting locked out. Overall, I'm very satisfied with the Kwikset 663 Deadbolt Unkeyed Deadbolt Lock. It's reliable, easy to use, and provides the security I need for my home. Five stars!
Review: Easy install - Ordered this because I live in an apartment complex and I don’t feel comfortable knowing employees could access our place. Our front door already had the hole for it so it was such a quick and easy installation since it fit perfectly. It comes with all the parts you need. It looks normal just your generic indoor lock, and great quality. I can sleep better knowing I’m safer now!

## Questions & Answers

**Q: Wow, there are a lot of conflicting answers here. Is this just a thumbturn lock for the inside of a door, and is it complete and functioning as sold?**
A: Yes, the one I received was a full functional single sided deadbolt. A single sided deadbeat means that there is no exterior side to this deadbolt. There is no key side as with a typical deadbolt or blank plate even. Keep in mind that the installation of these is different than a typical deadbolt. It does come with the thumb turn side and plate as shown in the picture as well as the bolt and internal door mechanism,  door frame plate, and screws.

**Q: Does this come with the exterior plate for the outside?**
A: No it does not. You can no longer use a key but just locks the door from inside

**Q: Can this be used to replace a keyed lock? I have a Kwikset deadbolt that is keyed on the inside and would like to convert.**
A: I tried to replace the inside keyed side of a kwikset deadbolt, but it didn't work. I decided not to return it since the price was so low and I felt like this was probably my fault for not researching enough. When this didn't work, I went to Home Depot and bought a whole kwikset deadbolt lock (both sides) for $5 more, which is what I should have done to begin with.

**Q: Is this replacing a deadbolt already in place? or does it come with the bolt?**
A: This is designed to replace your interior latch lever only. Mainly for a cosmetic color change. For example; sometimes people may have gold with the finish showing wear and they decide to change it out for another finish too.

### ⭐⭐⭐⭐⭐ Easy install. Works perfectly.
*by E***N on October 2, 2024*

I'm not sure what reviewers mean by a "back plate" for this Deadbolt. It's designed to be a deadbolt that is totally hidden from outside the door. If the door has been drilled through for a lock to be used from inside and outside the door, this deadbolt is not the right one. Those who say the screws that come with this lock aren't long enough are trying to use the lock on a deadbolt system that can be locked or unlocked from both sides of the door, but, it's not made for that application. It's a deadbolt designed to be locked from inside only when the user is inside the house or apartment.
