Cheaper and easier than adding another lock

Really helped in not letting our daughter out of the house. I was about to put an extra lock on the door but never got around to it. She had already figured out how to unlock the door. I saw this product and decided to give it a try. My daughter who is three still hasn't been able to figure out how to open the door with this on the knob.

Good quality,easy to install and arrived earlier than expected. My only issue is ordering another lock,maybe a part number in the package. I don't know how you can sell for under $12,00 plus free freight.

Easy to use -- no need for a locksmith (assuming you can jimmy your box open with the old lock you lost the key for!

Got this to replace a old beat up keyed Kwikset lock on my front entry door that looked like someone took a hammer to it. It was a simple install. Took me about 20 mins to take off the old lock and install this lock and program it. Couldn't have been easier! My neighbors saw me installing it and now they want one.

I installed this lock in a back door. Price was a factor. I would not have chosen the oiled bronze finish for a white wood door but it's on an enclosed porch...so who cares? (And the price for this finish was a lot lower than for other finishes.) also recognized the Kwikset brand. It installed easily after removing the existing deadbolt lock. An unexpected surprise is that it relocks itself after about 30 seconds. There are programming adjustments that can be made but I kind of like that feature.
I installed this lock so I don't have to carry keys with me when I walk my dog.

Wanted to keep my garage locked, but got tired of having to always have my keys with me to get in. This solves the problem. Works great. Full disclosure: I already had a Kwikset deadbolt installed, so I didn't have to install the new bolt from this one - just used the one I already had. The new hardware fits the same. Have had one of these on my front door for a couple years now, and it still works great. (When the batteries start getting low, it won't unlock on the first try; you have to enter the unlock sequence twice. Replace batteries and that fixes it.)

This is a nice lock. Maybe might be cut with bolt cutters but will deter someone just grabbing a loose bike. Easy to set combination too.

I picked up a pair of these when they were on-sale at Amazon.  This work great and I have no complaints.  They were easy to install, I had Kwikset locks already installed and replacing them with these was a snap.  It took longer to remove the old locks that it did to install and program these.  I'm very pleased with these.

I needed to rekey my existing shed lock but opted to completely replace it when I saw this one online.  It's really easy to install and appears to hold up to average weather (in NJ) well.  It would be nice if the key/cylinder could be replaced with one that had more pins but that's just me wishing.

If you are at all mechanically inclined, this will be easy for you to install.  It took about 1/2 hour, though if your door has non-standard holes or spacings, it might be more difficult.

The lock works easily.  It's nice that it can be locked without having to enter the combination; that saves a little effort.  Since all 4 numbers have to be entered in order, you have 10,000 possible combinations which should be pretty safe.

I reduced by one star because the aged bronze finish seems a little artificial.  It isn't the classiest looking door lock, though it's not bad.  And functionally it is excellent.

Easy to install, replacing old locks with more modern, and accessible version for when I am without keys. Battery replacement and programming is easy. Some small screws went missing (my fault in a remodel), but I was able to get the replacements from Kwikset quickly (but it took 2 attempts to get the right type of set screw).

I have a rental so this is WAY better then having a regular lock. I can change the code at any time and don't need to purchase new locks.

Convenient, great, and seems heavy duty. The boyfriend installed it on the front door and it took him about an hour because the area where the deadbolt goes, wasn't big enough. He had to shave and chip away at the frame.

Otherwise, if you have a normal set door, this should do the trick.

After reading reviews of many locks, and watching videos of locks being quickly broken, I selected this one - installed easily, and seems more secure than the ones I watched videos on.  Hopefully will do the trick in the high theft area this unit is going to!

Local dealer wanted to charge over $300 for this lock with installation.
I did it myself in 15 min. for a total of $65
what more can be said. This is a five star purchase!

This lock was really easy to install and only took me two days to get it in the mail. I really like it. The lock only took about five minutes to install.

Love the keyless entry, and no longer having to worry about losing my keys! Directions were a bit more complicated than necessary the first time, but purchased a second for another door and took less than ten minutes. Solid lock and easy to use.
