The Kwikset 660 Deadbolt has been my go-to lock for rental properties for years. It's a reliable, sturdy deadbolt that's easy to install and looks good in a matte black finish. I've never had any issues with these locks, and they provide the level of security I need for my rentals. The re-key feature is also incredibly handy for tenant turnover - it saves me time and the cost of replacing locks entirely. If you're looking for a durable, affordable, and no-hassle deadbolt for your rentals, I highly recommend it.

I like the look of the lock, it was easy to install and it functions smoothly. The only downside is the deadbolt itself is not that thick, so if you're concerned about security you may want to consider checking the specs more closely.

Smart key worked as expected. Easy install and accepted my ‘Callan’ made key. Super easy rekey feature on manual took 5 minutes.

The newer ones like this are way easier to install than the ones from years ago. Less components, simple visible screws, super straightforward re-key trick. Literally takes 2 minutes to install and works perfectly for years.

I love the Kwikset 660 Deadbolt! The re-key feature is fantastic, it gives me a peace of mind that I can easily change keys if I need to, without calling a locksmith. The SmartKey Security technology is a big plus, it's pick resistant and makes me feel secure. The easy self-installation was another feature that I appreciated. It was simple and straightforward. Overall, this product is a keeper!

This is my second purchase. It's overall quality is good, but not up to a commercial grade which is fine for me as it's installed at my home. The rekey feature is a breeze to do.

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.

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.

It's a good quality product, that's why I ordered it again, but haven't received it yet.

The lock came fast and complete. This would get you 5 stars. However the photo they use to sell is a “Smart Key†where you can re-key yourself. As you can see in the photo there is no slot for the Smart Key tool. This gets you 2 Stars. BUYER BEWARE!
