Packaging: Shipped in a brown Amazon box. The products were nicely packaged in red and black branded boxes with clear plastic to see the product inside.Product Impressions: We bought 3 of these for a new home. Came with all pieces of hardware and was super simple to install. Just note this may not fit every door due to sizing. Make sure to measure before installing. Please also note: REKEY THIS IMMEDIATELY. I tested and confirmed all keys are the same for all 3 meaning if I was a thief and saw you had the same lock, and you didn't rekey it, I would technically have a key to your home if I ordered the same product as you. We rekeyed ours immediately.Usability: Worked well on our doors- hopefully it lasts a while.Overall Thoughts: Great and affordable product- just wished they made it more clear to people to rekey these.

I was a little bummed out that I had to replace a door handle on my house since they are all keyed the same and it meant having to either settle for another key on my ring or get the new lock tumbler changed. I really didn't read the part description very well and just bought a replacement Kwikset handle. OMGosh I was delightfully surprised. I removed the old one and put this one in. It was easier to install than the old due to a engineering change in how the screws that hold the two handle halves together are designed. Great work Kwikset. The best part of the new lock though is the smartkey security feature. It very simply allows you to mechanically program your old key to use in this new lock. Wow! that was fabulous. I guess it doesn't work with all old lock-sets but I am fortunate that it worked with mine.The lock-set feels sturdy and works very well. I cannot attest to how long it will last but it seems well made and so far is working great. I could not be happier with this product and highly recommend it to anyone that needs a new lock-set. Thank you Kwikset !

We have double-glazed, steel-faced French doors with internal venetian blinds, opening to an exterior patio area. The doors came with low quality door hardware knobs that have been a pain. We therefore replaced this hardware with the Quikset Tustin Keyed Entry Lever, with Satin Nickel finish to match all internal Kwickset door levers in the house.Written and diagrammatic instructions in the carton are very clear; written and drawn by people who have aced how to communicate with non-tradespeople, with step-by-step progression thru the installation process. All needed parts are provided in the carton, each set of parts being secured in a sealed plastic bag or compartment. Again - someone has given a lot of thought to ensuring a no-hassle installation process. There's a 1-800 number to call for help if need-be.The hardware depth is easily adjusted for door thickness from 1-⅜ to 1-¾ inch (the latter being what we needed) and the levers are easily positioned to (i) face left or right, inside and outside, and (ii) have the lever with the key slot on the outside. Whatever orientation you want will be achievable. The carton includes two new door keys.We re-keyed the new lockset so that we could continue to use the keys from the old lockset we were replacing. The process is simple and easy, requires only a small tool (provided in the carton) and takes less than a minute. It does, however, require the old key to be of a KW1 type - meaning that the long grooves on the key will let it slide into the new lock.The lockset is certified for its security level and has a Lifetime Warranty. The satin nickel finish on our internal door levers, now 8 years old, has proven to resist ageing and to be very easy to wipe clean. We are hoping that the exterior patio door lever, exposed to south Texas heat, but not direct sunshine, does the same.

This was an easy replacement of my worn out Kwikset doorknob. It looks nearly identical to the contractor installed door knob that has lasted 12 years. The install is direct and easy to follow in. The action is very smooth. One of the best features is that you can rekey the lock to the original key that you had from. The contractor installed locks. So you don’t have to involve a locksmith to rekey the lock for you. There was only one minor flaw on the knob, a little rough spot on the edge of the knob, but that wasn’t a big deal for me because this is on my garage service door. I have had to replace other door knobs and locks in my house and they have all been up very high-quality. I would recommend this product for any homeowner.

Solid feel you grab it to open the door. Easily installed and rekeying could not be simpler.The lever has come in handy when my hands were full from the grill to open the door.The boxes were new and unopened, as others said theirs were open, these had all parts and instructions.
