  • Rated 5 out of 5 by from Great product and customer service! I decided to replace the front and back door hardware on the new beach home I purchased. Since both are glass doors, I chose a double cylinder deadbolt. I originally ordered 2, but one that was sent was not correct. I contacted customer service and they immediately sent me a new one and a pre-paid shipping label to return the other at no charge. I am very pleased with both the lock and the customer service I received. Also, Kwikset will enable me to change the lock any time I like without the need for a locksmith. This is an important feature over other lock manufacturers when you have a property that you might rent.

    Rated 5 out of 5 by from Excellent product! We purchased this item to replace our keyless deadbolt lock. Excellent product! Easy to re-set so we only have one key to use on both the door knob lock and the deadbolt lock. We feel much safer now since the door this is used on is a 15-pane French door.

    Rated 5 out of 5 by from Double lock set These are excellent lock sets. They are easy to install and very easy to change keys if you follow the instructions.

    Rated 5 out of 5 by from exactly what I needed and exactly the right price I bought this a few weeks ago and have already changed the locks about 12 times (it's for a common area conference room) and have had zero issues with it. It takes about 3 seconds to change the lock now- no joke. we looked everywhere local for a simple design but they only had much more expensive sets so this is just what we wanted.

    Rated 5 out of 5 by from Simple and easy Matched exactly what it was ordered to replace. Love the re-key feature and re-keyed in and outside lock. Took a little extra time to install and finish but not excessive.

    Rated 5 out of 5 by from Easy install, easy re-key. Pretty simple install. Don't have any reason to expect problems over time.

  • I have an apartment complex I am designing the keying system for. Can these locks be master-keyed where one key opens all deadbolts within the complex?

    I need to purchase a kwikset 665 double cylinder deadbolt in venetian bronze. I'm buying it to match a bunch of other ones I already have. They matched key code on the old box was 12540. How do I purchase one of these?

    Asked by: jampurcell
    Hello jampurcell, Thank you for your interest in Kwikset model # 665-11P-SMT. These locks may not be ordered using the same key code on the box. This lock features the Smartkey Technology that will allow rekeying of the lock to the existing key that you would like to use in the lock with out the use of a lock smith. Thank you, Kwikset Support Team

    I want to convert a single-cylinder (with thumbturn) to a double-cylinder, but the external finish (Venetian Bronze) is different from the interior finish (Brushed Nickel). Can I order a double-cylinder deadbolt with two finishes?

    Asked by: Kevin54
    Hello Kevin54, Kwikset does not manufacture mixed finished products. You will need to purchase two double cylinder deadbolts in the desired finish and mix and match the two. You can not convert a single cylinder deadbolt to a double cylinder deadbolt, they are not compatible. Thank you, Kwikset Support

    How do you rekey this deadbolt to be the same on both sides? I followed the instructions, but it only works on the first side that was rekeyed. The other side is now locked and doesn't work with either key (original or new).

    Asked by: MShelt
    Hello MShelt, Both sides of the deadbolt would need to be re-keyed to the same key you want to use because they are 2 separate cylinders. Thank you, Kwikset Support Team
