With this kit I swapped the cylinder and followed the re-keying process to use my old key. Now I have an extra key just in case I need to change the whole house. Works as advertised . Easy to install. Good price for store price was $6 dollar more..

Amazon Customer: Easy to install, easier to replace the keys. Nice knowing they’re more secure than the average deadbolt.
The kit comes with a pair of 2 keys and the piece needed to rekey it, as well as the deadbolts and screws, etc. All super easy to put together. The only potential downside is the outside lock mechanism might be a bit wider than the standard deadlock hole, or that could just be our door. Either way lock and everything still works well with it.

Vanessa Stewart: Everything was great with exception to how long it took to install because the two screws wouldn’t lineup. Other than that everything was perfect. Not sure why the lock has a small slit near the key area. The slit concerns me but outside that it’s a nice color, appearance great, very sturdy and 20 min install.

Joe: Recently, my front door deadbolt lock broke. I was floored ! 5 years old. Made by Schlage no less. Never thought a Schlage lock would fail, but it did. Took it apart. Found PLASTIC parts inside it ! And that's what broke !!!!! So, bought this Kwikset. 1/2 the price of Schlage. No plastic parts inside it. I am very comfortable knowing that this lock will last a long time. Highly recommend.

C. Noble: 4 people are using this lock. 2 of the keys are quite worn, one close to brand new, and one somewhere in between. I used my key, one of the quite worn ones, and those two work perfectly. the in between one works reasonably well, but is a little crunchy. the new key does not work. when set with the in between key or the new key that key is the only one of the 4 that works
these keys all work on the older standard kwikset on the back door.
this is good from a security perspective, tighter tolerances makes it harder to pick. its less good from a usability perspective, as over the years your key will wear down and eventually stop working. not that someone will be picking one of these anyway, they're quite challenging to pick and are somewhat weak to twisting attacks with a flathead screwdriver.
I think the strategy here is to probably keep an extra key that you don't use and use it to get duplicates made whenever your keys start to get crunchy.

ROBERT K.ROBERT K.: It's a good quality product, that's why I ordered it again, but haven't received it yet.

Amazon Customer: This lock fits in one of my doors just fine. The self key feature is a plus if you already have other locks with a KW1 keyway.

GABO: Fácil de instalar ya que tiene las medidas entandar de todos los cerrojos similares. El único detalle que no me gustó es la perilla de cierre por dentro. La perilla no queda firme al cerrar. Aunque si cierra bien, la perilla queda un poco floja, no da esa sensación de seguridad de otras perillas que hacen clic girarlas. De cualquier forma cierra bien ya sea con la perilla o con la llave.

SleepBreatheDoc: I also like that it didn’t come in a huge wasteful package. Everything necessary was there and we now can get into our house - the last electronic lock broke!
