Deadbolt
This deadbolt was very easy to install and fits perfectly in the place of my old worn our deadbolt. I love that I. Was able to re-key my lock myself without having to take it to the hardware store or hire a locksmith. The deadbolt functions smoothly and looks good. The price was very reasonable.

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.

Perfect for my rentals
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.

Heavy, good quality lock.
I love smart key locks. I buy these for my rentals, so I don’t need a locksmith when tenants move out. The matte black finish is attractive, although it may get hot in the summer. I like the heaviness of the 660 and Cove series. It gives a nice first impression, that it’s not a lightweight, cheap knob and lock. I wish the price was a little less, but I’m happy with my purchase.

Easy to install
This was so easy to install. I was able to install it in under 10 minutes. So far, no issues! Sometimes it sticks a little bit, but itâs likely due to the humidity and heat of the summer.

Easy to install, easier to replace the keys. Nice knowing theyâre 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.

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.
