  • 780 Single Cylinder Deadbolt in Polished Brass is rated 4.2 out of 5 by 25.
    Rated 4 out of 5 by from great features I love the ease in which you can re-key your locks. I regularly re-key my front door so that a neighbor can gain access and feed my dogs. I would trust him anyway, but when I don't need him to have access, easy peasy

    Rated 5 out of 5 by from Simple and Reliable Had to replace our deadbolts on all of our doors. They came with easy to read and understand directions. Very easy to install. And very reliable to use. All deadbolts should be easy to use.

    Rated 4 out of 5 by from simplicity of changing key I have been using smart key deadbolts for rentals because it is so easy to "change locks" for incoming residents

    Rated 1 out of 5 by from Poor security on all Smart Locks. You can open any of the smart lock series with a flat head screwdriver and a pair of pliers for a little better grip. Just stick the flathead screwdriver in the keyhole, and just turn it back and forth a little bit, use pliers/vicegrips for a better grip. Just for a few seconds keep turning back and forth as hard as you can and you'll feel it start to give, and in a pretty short period of time, then it will just give and turn. 30 second , maybe a minute, and they are in. Sidebar is made of cheap plastic and gives under a little pressure. Granted you can't pick them, but you can break one with just as much ease and a lot less skill. It's convenient for any little thug with common tools to get in.

    Rated 5 out of 5 by from Great for rentals! I have purchased at least ten of these over the past three years. The lock works well and the finish still looks good. I have re-keyed one of them three times, due to tenant turnover. This has saved me more than the cost of the lock. Before I had to take the lock off to bring it to a locksmith. That meant that I had to put a temporary lock on the door until the re-keyed lock was returned. Then I had to pick up the lock from the locksmith, take the temporary lock off, put the re-keyed lock back Now I can re-key a whole house in less than fifteen minutes. Of course, ease of use and good looks are just the cover story. One of the rentals was broken into, but not through the door. They tried to jimmy the lock, but were unsuccessful. The thieves then threw a brick through a window, setting off the alarm. LOVE THIS LOCK!

    I have a Kwikset deadbolt that is lose and spinning. There are no visible screws on the inside to tighten.  I took the inside handle off so I could remove the inside plate and find the screws but the plate would not come off.  How do I get this task done?

    Asked by: JohnJ
    Hello JohnJ,Thank you for your interest in Kwisket model #780 L03 SMT. This model has visible screws located on the interior plate. These screws are holding the interior deadbolt to the door. If you do not see the screws on the plate, the model number you have provided may the the incorrect model number. The model number you may have is the #980 series. This will require a 1/16" allen wrench to loosen and remove the small set screw located under the turn piece on the interior deadbolt. Once this is removed the turn piece will then have the ability to be removed as well. At this point the cover plate that was held on by the turn piece should come off, and expose two more mounting screws under the plate.If further assistance is needed please contact Kwikset technical support at 1-800-327-5625.Thank you,Kwikset Support

    what is the difference between the single cylinder and double cylinder deadbolt and will either lock key be compatible to the lodi door handle?

    Asked by: jimbob12
    Hello jimbob12,The single cylinder deadbolt is keyed on the exterior side of the door and has a turn piece on the interior side for locking and unlocking. The double cylinder deadbolt is keyed on the interior and exterior side of the door for locking and unlocking. If the lodi door handle is a Kwikset Smart key compatible lock then you may rekey the lock to the same key as the deadbolt.Thank you,Kwikset Support
