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!

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!

Easy install. Works perfectly.
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.

Rod might be too long ;)
Just a REMINDER that this is a HALF-BORE dead bolt. Which means only half the door is drilled out to fit and don't go all the way through. So don't buy this expecting a key for it. This idem is very hard to find in hardware stores or even order through them with claims they have it. They don't... Amazon came in with the save; product is true to color and hardware included. My only issue I had was, the center rod that turns the lock was too long to secure fitment. So, I cut the rod 1cm with a Dremal to make fit and now works perfectly. I'm not sure if the center rod is supposed to be longer for different applications but works fine now.

Heavy duty and put on a door that has been picked every week
This is a very heavy duty lock. But it does not come with a back plate. It is the strongest one that I have found and it is heavy duty. Just need one with its own back plate.

Works as it should
Just installed this today after I got out of work. Quick and simple installation. Definitely worth the money and it fits perfect. If you're looking to replaced a damaged deadbolt, just get this one.

Item works, but could be problematic in the future
I really like this product, though I wish it was a little heavier, it's lighter than the other kwikset deadbolt that I purchased. The only problem I ran into with this single-sided dead bolt was that the plastic piece which allows the screws to hold it in place was too long for the existing hole that I had. I had to drill an additional hole for this item - the problem wasn't drilling the hole it's the concern I have regarding this product breaking like it did last time. The reason I needed a new one was the old thumb turn broke and just spun in place instead of unlocking the door. We were able to open the lock and slide it out from inside the house. Now that I've drilled it securely in place, if this issue were to ever happen again, I'd have no way of sliding it out. For those in a similar situation, be aware that if this lock were to break while it's locked, you're going to have to cause considerable damage to the inside of your door to get it back out.
