Kwikset 991 Tustin Entry Lever and Single Cylinder Deadbolt Combo Pack featuring SmartKey in Satin Nickel, Model Number: 99910-040

Super easy to rekey One key for all doors in the house and shop

We bought a new house and wanted to change all the locks—we have FIVE exterior doors (all with deadbolts) and wanted the convenience of using ONE single key for all of them without calling a locksmith. We also wanted to change out old brass locks/knobs/levers with a more modern look. This was the PERFECT solution. First, I purchased an inexpensive but good quality set of 4 locking knobs with 4 deadbolts on Amazon—all keyed the same with a key compatible with Kwikset. I used those on the basement, balcony, and garage doors (with one extra left over). Then, I purchased a Smartkey handle-set with matching deadbolt for the front door and keyed that to match the 4 set combo. Then, I purchased this Smartkey set for the patio french door and also keyed that to match the 4 set combo and the front door. YAY! All doors in the entire house use ONE single key. The price for this deadbolt entry lever set on Amazon was an unbelievable $17 LESS EXPENSIVE than in our local big-box DIY store. It was very easy to install this, and very easy to key it. I simply followed the instructions in the package. It also works exactly the same as the Smartkey handle-set on our front door. Remember to keep the Smartkey pin in case you need to ever re-key the lock again. I think that that feature is VERY handy in case you ever feel a need to change your locks. You can do it yourself at no cost. All you need is whatever new key that you want to use. Overall, I love this product!!! If my review was helpful, please let Amazon know by clicking “helpful”. Thanks.

Solid, quality feel. Great finish with long guarantee. I bought two sets and performed the rekeying. No problem if you follow instructions carefully. I did find that the installation in existing doors was trickier than I though. I had to do some routing, chiseling, etc. The tolerance was tighter with this set than the old hardware it replaced. The deadbolt with this set is Grade 1, the highest level of security. The strike plate (not shown in the photo) is the difference with four screws rather than the more common two. Additional screws are about 3 inches long.

Pretty, the locking mechanism is a little loose. Works ok

Nice look way easy to open doors. Had them deleted to be alike.

Overall, this was the easiest install to replace a door knob and deadbolt. I am 68 years old and was hesitant due to the original ones being over 15 years and hoping the new ones would fit properly. The hardware had components that were adjustable to fit different size holes. Took less than an hour to remove and replace the knob and deadbolt. They look great. Highly recommended.

Loved it. Looks and Feels high end. More than meeting my expectations. Really took me by surprise as the quality is amazing. My previous lock came with the house and had to replace twice within 9 yrs of moderate use. Decided to go with this design so we can use old keys. Was able to program my old keys within seconds. Instructions were pretty clear and install shouldnt take more than 30 mins especially if you are replacing existing lock. Definitely recommend it.

Bought 3 of these for my place when I first moved in. Install went easy enough, parts are decent, mostly. When installing the deadbolt on one door (we had to do other repairs to the jamb before installing that lock) I checked both locks to make sure they functioned. Thats when the handle portion had an issue, where the key spun, but it did nothing. Pulling the unit apart, I found this casting flaw caused the locking rod to snap (casting or sintered , looks similar) and the lock is not functional. Used Kwiksets support site, thought the process was going quickly, until they told me that parts delivery is 6-9 weeks and a standard piece is a custom order. Id be better off to make one myself, or buy another lock. Nice lock system, just hope it does not fail in any way or you are SOL.

They fit the door great and i like the look of them. Was easy to install, the directions were good. The smart lock feature is so nice. Now all my locks are the same key. Pay attention to the directions when you use the smart lock to rekey. They came with 2 keys but it sure would be nice if they shipped 4. Oh well, getting extras cut at the hardware store wasnt too expensive.

Great quality locks.
