  • 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 A great purchase I purchased this lockset for my new doors. I chose the double cylinder because half of my door is glass and feel that it is more secure. I appreciate that it is a double cylinder with the smart-key technology because my locksmith said this option was not available. Now I feel secure in my home and know that if I need to change my locks, I can do it myself and not pay to have locks rekeyed! Thanks for making this possible.

    Rated 2 out of 5 by from Short lifespan I use the Smart Key knobs and deadbolts at my facility. The rekey option makes it very easy to change as needed. However, the latches wear out very fast at the handle turning mechanism point of contact. The deadbolts do not hold up well, the keyway starts floating, and sometimes the keys will get stuck or the keyway will not return to the starting position. I contacted customer service for warranty or repair and was told they do not warrant the product in a commercial setting and do not do repairs on their own locks. Very disappointing.

    Rated 4 out of 5 by from Just what I needed. After 30 years of daily service one of two Kwikset Double Cylinder Deadbolt Locks failed. The lock cylinder came out with the key. Thirty years is pretty impressive; so I decided to hunt up two more keyed alike in Antique brass to replace the original "Bright Brass" locks. The doors required very minor trimming with a chisel for a perfect fit and because my doors were 1 3/4" thick it took a little fiddling to get the inner mechanism and bolts to line up. It would have been helpful to have had a third hand. The lock operates smoothly and the bolt extends adequately into the door jam. For my situation the Kwikset locks were a good solution and great value. I was happy to find theses locks here and in a finish that compliments the old door and hardware.

    Rated 4 out of 5 by from Locks excellent, customer service bad Every thing was great, except two of the locks did not have keys. They promised to send them, but they keys they sent Schlage, not Kwikset! Schlage keys don't fit in a Quikset lock. I'd rather not have to call repeatedly to get what I ordered.

    Rated 5 out of 5 by from excellent experience This double cylinder deadbolt replaced a thumb knob deadbolt. Since the old set was a Smartkey model, the installation of the double cylinder lock was a snap. The ordering, shipping and receiving process made this purchase a winner.

  • 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?

    Asked by: Truitt
    Hello Truitt, Thank you for your interest in Kwikset model # 665-15A-SMT. Smart key locks can only have one functioning key per lock. These locks can not be master keyed.

    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
