If I order 5 deadbolt locks together, will they all be keyed alike?

Kwikset Model # 660 5 SMT SCAL SCS
Asked by: Anonymous
Kwikset does offer keyed alike products to consumers to choose from in order to have the same matching key. To identify this product, please see the "Keyed Alike" sticker located on the box to find the matching keyed entry unit. Note; Kwikset makes up to 6 cases with the same key, no more than that. Special order is required for additional quantity. The Smart Key feature will also allow you to instantly resolve issues of product being keyed alike if you choose not to have the same matching key.

660 Single Cylinder Antique Brass Deadbolt Featuring SmartKey is rated 4.2 out of 5 by 11.
Rated 2 out of 5 by from bad changes new kwiksets not easy to install i'm replaceing old kwikset with new ones these don't allow for any leeway at all !!!!! where old ones were adjustable and very easy why change a good thing???? ya need to make your products for average homeowners!!!

Rated 1 out of 5 by from Worst on the Market If you are looking for security do not choose this deadbolt. If you are using the smartkey, expect it to fail within a year. These locks are made from potmetal and meet the minimum grade of the ANSI standards. DO NOT BUY!!!

Rated 4 out of 5 by from Deadbolt locks that are easy to install If you ever need to change your Deadbolt & key the Kwikset components are almost universal. This means that one can usually change out the cylinder and use all the old hardware and latch, the part that moves in & out. The Kwikset brand is especially handy for landlords that need to change locks quickly & often. Another bonus Kwikset give you is the fact that repair parts are often in stock at your local hardware, and the keys somehow duplicate easily & correctly. I can't tell you how many times I've had a key made for a different brand and it didn't work. Kwikset duplicate keys always work the first time for some reason. A little security tip; if you use a foot or so long piece of plumbers strap (metal tape w/holes) screwed along the wooden door frame (behind the molding) to reinforce the hole for the latch - it makes it very difficult to kick in the door. If you need keyed alike locks, the key codes are on the package. So you can match up as many keyed alike locks as needed.

Rated 4 out of 5 by from Great for rentals and vacation homes Hard to beat this option for the money! Worked flawlessly and effortless. Took me about 5 seconds to reset this lock to any of my conventional exisiting door keys. Tenants and visitors now can have easy access to some house and garage, but not my storage/maintanece closets. In seconds I can re-key and have complete access with just one key when necessary. Shipping time was disappointing. Took over two weeks to ship from CA to AZ (ship to store option)...could have walked that distance faster.
