Simple, solid deadbolt. great value and easy swap for rentals
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.

I Hear You Knocking
I purchased this Kwikset Deadbolt Lock when the one I was using became difficult to open and lock. I found it to be a quality lock and operates smoothly. The “How To Install” video was really helpful and appreciated it. I am 78 years old and had no problems installing it. I haven’t rekeyed it yet as I’m deciding if I want to change my entry lock. All and all this 660 deadbolt is a very nice and affordable lock.

Easy Intall, Perfect Fit and Rekey
Worked perfect, easy install with instructions online. The finish was more like matte black, so it doesn’t match perfectly.

REKEYABLE!!!
I recently installed a new set of locks on my house. I like the look of this little lock as it fit the aesthetic of my new door handles.The most important thing to know is that these are rekeyable. I won’t post how to here, there are very detailed instructions on how to install the lock and then how to rekey it so that you only need one key not a whole ring of them.Installation is not straightforward. There are certain things you need to make sure you are doing right or else your lock won’t work.1. On the side of the housing for the mortice latch, it tells you proper orientation of the lock so you don’t install it upside down. Yes it can be installed upside down – but it won’t work.2. It can be done by one person. I installed all of mine without help, but having someone to help hold the exterior piece in place while trying to attach the inside section to it, can help a lot.3. Maybe this should have been number 1, but make sure you line up the door latch with your placement of the receiver hole in the door frame. Somehow I lined mine up on the first door completely by accident.This is a solid material build quality. The housing is steel but there’s a brass housing inside the steel box. It keeps the entire assembly centered in the drilled hole for the lock.

My Go-To Deadbolt
I recently purchased this deadbolt for my front door, and I couldn’t be happier with its performance. The installation process was straightforward and took me less than 30 minutes with just a screwdriver. The instructions were clear, and all the necessary hardware was included, making the setup hassle-free.One of the standout features is the SmartKey Security, which allows me to re-key the lock myself in seconds. This added flexibility is a game-changer, especially if you need to change keys without replacing the entire lock. The lock feels sturdy and well-made, providing a sense of security for my home.The satin nickel finish gives it a sleek and modern look that complements my door’s aesthetics. It’s not just about looks; the lock operates smoothly, and the key turns effortlessly without any sticking. I also appreciate the Microban protection, which keeps the surface cleaner and more hygienic.Overall, this deadbolt offers excellent value for the price. It’s a reliable, secure, and stylish addition to any door. If you’re looking for an easy-to-install lock with the added benefit of re-keying flexibility, this is a solid choice.

Good lock.
Installed a new door slab and needed a deadbolt as the old door didn’t have one. The door had a hole already drilled for the lock so was an easy install. When using it feels like a sturdy, quality lock. I like the Kwikset because all my locks are keyed alike and is simple to do and literally only takes a minute.

Easy to install, easier to replace the keys. Nice knowing they’re more secure than the average deadbolt.The kit comes with a pair of 2 keys and the piece needed to rekey it, as well as the deadbolts and screws, etc. All super easy to put together. The only potential downside is the outside lock mechanism might be a bit wider than the standard deadlock hole, or that could just be our door. Either way lock and everything still works well with it.

I needed a US style deadbolt for my door so I ordered this lock from the Lock Door seller for 893 rupees which is cheaper than what it costs in US which is typically from 12-15$ for the same one. Other sellers have priced it much higher around 3000-4000 rupees which would be the actual cost if you import this lock from amazon.com. As I expected the lock was a replica as I have seen the original one which I bought in USA. The quality is poor but the lock does the job and is not flimsy. I have installed it on my door just like a regular USA deadbolt and it works fine for a secondary lock. I would not advise to use this as the only lock on your main door.

15年前にアメリカのHome Depotで購入したドアハンドルのDeadboltが壊れ、外から施錠・解錠が出来なくなり途方に暮れていたところ、この商品を発見し故障翌日には修理が完了し、最短の期間で外出できるようになりました。この商品の良いところは、付属のSMARTKEY toolを使うことで これまで使ってきた鍵がそのまま利用でき、家族用のスペアキーを作り直す手間と費用を不要にできます。鍵のメーカーは異なってもアメリカの通常の鍵(ディンプルキーはダメ)なら互換性があるようです。このようなアメリカ製品の合理的なところはとても良いですね!

Needed to replace an existing lock that is > 20 years old. Easy 10 minutes swap. Fortunately all holes sizes and alignment are the same. Instructions are very clear and straight forward. Would buy again.
