It’s a great investment if you own more than 1 house. It saves lots of money. Lock looks great easy to rekey and the best of all lifetime warranty that comes with and the great customer service you will get in case you need help. I strongly recommend kwickset to anyone

    Brand new deadbolt installation. Inside knob works. Key will not rotate. Entire cylinder is rotating, but key itself will not turn. This does not have SmartKey feature. Troubleshooting requested!

    If I am buying 7 kwikset 660 can they come with one key that fits all?

    Asked by: Kim
    Hello Kim! Absolutely, when adding to your cart. You will need to choose from two option, keyed alike or keyed different. If you choose keyed alike, all locks will come keyed the same.

    If I order three of these will it come with the same key or three different keys?

    Asked by: Jen
    Kwikset manufactures keyed alike units that are up to 6 boxes to a pallet. The SmartKey technology allows rekeying the lock at any time to the other Kwikset key. The model number on the package K2, K3, K4, K6 would indicate the number of locksets that have the same key. Please contact build.com for pricing and availability.
