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.

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.

This Kwikset 660 deadbolt is a great value, especially compared to what you'd pay in most big box stores. Installation was quick and straightforward—took me less than 10 minutes with just a screwdriver. The lock comes with two standard keys plus a temporary one, which is a nice bonus if you're doing any short-term access or need to hand one off during move-ins. The SmartKey feature is one of the main reasons I keep coming back to Kwikset, it makes rekeying super easy without needing a locksmith, which is especially helpful if you're managing multiple properties. The lock feels solid, the satin nickel finish looks clean and modern, and the Microban protection is a nice touch for high-touch areas like front doors. My only real gripe is durability. This is actually a replacement for my first 660, which started rusting after only three years. I live in a humid climate, so that may have contributed, but I was still surprised it didn’t last longer. I’ll be keeping an eye on this one over time. Overall, it’s a strong and reliable deadbolt with great features and a reasonable price. Just know it may not be the most weather-resistant option out there.

Great quality and easy to install. Took about 10 minutes. Looks nice. Turns nice and smooth.

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.

Not a lot to say about this one, but it works well and seems better made than some I've used costing several times the price. I didn't see this mentioned in the listing, but it has the feature where you can re-key it to match your existing (kwikset only) key if you want. I was putting it in a door that is never accessed from the outside so I didn't bother but I've got a couple with the same feature on another building and they still work smoothly, and they've held up for 7 or 8 years so far. These are not high security locks but most crooks don't pick locks. They use a wrecking bar, kick doors in, or just break a window. These are still stronger than most residential door frames so unless you've reinforced yours of bought high quality doors and frames, they're more than adequate for most folks. All in all, a decent lock for the money.

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.

جودة ممتازة

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.
