    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!

    Rated 5 out of 5 by from Kwikset 780 Single Cylinder Deadbolt in Antique Br I have two (2) installed on my doors with the 740 Juno Entry Lock in Antique Brass. I like the smart key function so I can re-key both locks as necessary without having to take the cylinders to the store for re-keying. The installation goes together in a few minutes. Anyone can install this lock in an existing opening. We like the antique finish and the locksets work smoothly and perfectly. I'm a Kwikset consumer for life.

    Rated 4 out of 5 by from Nothing is Nicer Looking Brass is a rich look and worth the price. The lock itself is efficient and solid. Stopped someone from breaking in our home. The lifetime finish is a tough to guarantee, yet the company has replace 3 of 7 no argument. Those were by our pool and pitted. This is why you buy the top line product, quality and service.

    Rated 1 out of 5 by from SMT key,not so smart I'm a local mobile Locksmith, not a distributor. I have trouble with the Smart key system. I have had several cylinders fail. I have some that don't work in the cradle. When a SMT is on the only door and there is no key the options are limited, compared to picking or the cost of a cylinder if you have to drill.
