  • Rated 5 out of 5 by from Double cylinder locks I live in a manufactured home and all my outer locks have been deadbolts with double cylinder locks. I've been a widower for some time now and a woman who thought she knew more than me took a key when I was leaving on a trip for several weeks. Shortly upon returning I realized I wanted nothing to do with the woman who now said she couldn't find the key. I ordered from Kwikset and your company was recommended. I'd never changed a lock before in my life. It was so easy I was surprised and pleased. [This review was collected as part of a promotion.]

    Rated 5 out of 5 by from Expert Customer Service I bought my door locks several years ago. One day I had a locking issues and contacted customer service. They quickly sent me a replacement. A few moths after the replacement encountered complications and once again, I contacted Quick Set customer service and they replace the entire door handle and lock assembly. Their customer service is unmatched to any other company.

    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 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.

    The model 665-15 instructions state that the Latch is provided with a flange (item A) or without the flange (item K). Your web site shows no option for a Latch without the flange; which is what I needed and wrongly purchased. So what is my alternatives?

    I have a customer with a KW10 key. Wants 5 single cylinder satin nickel deadbolts. Our DIB website does not specify which key works with which deadbolt. Suggestions please I have to order by 5 today to get it on Friday's truck.

    My existing deadbolt "mechanism" is only 2 1/8 inches long. How long is the deadbolt "mechanism" on the kwikset 665. By "mechanism" I refer to the part that slips into the door and operates the bolt. Please advise, thanks, Robert

    Hello. The cylinder guard and cover on my 2002 kwikset keyed deadbolt is failing on the inside lip which holds the cylinder. I can't really tighten it too much anymore as the entire thing becomes unsupported as the lip is too thin. Can I get a new one?
