Kwikset 780-S Reviews

Rated 5 out of 5 by from Nice Solid Smooth Action We are loving our new deadbolts. maybe it's just because our old ones were so, well, old. We had to push the door and fiddle with them to get them to turn but these are a breeze. They feel very solid and secure but I can literally lock the door with the swipe of a finger. Great piece. And the SmartKey function? Genius. Just had a bunch of contractors over and re-keyed the whole house for their access in like 10 minutes. Now that the work is complete I changed the whole house back to the original locks. Perfect!

Rated 2 out of 5 by from Fair Not impressed and would not choose Kwikset again. Some of the locks have trouble turning with the key. Constantly jamming up. We are removing them very soon.

Rated 5 out of 5 by from Big Improvement Hugely better than what the builder installed. Looks and works great.

Rated 4 out of 5 by from Heavy Duty Beauty Looks great and operates smoothly. My only complaint is the cheap finish on the keyhole. It looks unfinished. Ideally, it should match the rest of the lock, but they should have put some kind of finish on it. Very simple install and perfect fit. Great product, great price, great service...I am very happy with

Rated 4 out of 5 by from Good Product Good product, a big improvement over the 1975 version it replaced. Solid and well made. I have not had a chance to try the "smart Key" function yet.

Rated 5 out of 5 by from Replacing all locksets/doorsets at my new home. The ext handlesets with the smartkey feature worked great and was very easy to do. One key fits all. I would purchase this deadbolt again.

Rated 3 out of 5 by from Good Purchase with Reservations Bought two sets of the single cylinder locks with matching Hancock handle sets utilizing the Smartkey function in antique brass. The single cylinders function flawlessly however, the antique brass finish does not match the antique brass finish for the Hancock style handle sets. Antique brass in any of the Kwikset cylinders (including the double cylinders) and matching handle sets should be a uniform color. It's my opinion that this variation in color is a quality control issue for Kwikset which can be corrected at the manufacturing facility even though the facility is outside of the USA. If there was no color variation, I would have given 5 stars.

Rated 5 out of 5 by from Easy First of all, was a great place to purchase these - they have amazing prices - I looked at the Big Box Stores first, and those prices were incredibly high (at least 30-50% higher than here). Replaced all the deadbolts in my house with these, keyed the same way. Easy to install. Very satisfied with my purchase.
