Customers say
Customers find the door knob easy to install and appreciate its appearance, with one noting its modern “coastal” vibe. Moreover, the product offers good value for money as a budget lock kit. However, the quality receives mixed feedback, with some finding it excellent while others describe it as super cheap. Additionally, durability is a concern as the black paint chips and peels, and functionality is mixed with some saying it works smoothly while others report deadbolts not working. Moreover, the lock quality is problematic, with customers noting it doesn’t lock properly and the deadbolt only works from the key side. The sturdiness also gets mixed reviews, with some finding it solidly built while others describe it as flimsy.

Sleek Coastal Entry in Minutes
I just installed these door knob and deadbolt set on my 2 garage doors, and Iâm genuinely impressedâespecially for the price. The matte-black finish has that modern âcoastalâ vibe without feeling trendy, and the hardware feels solid and well-made.Effortless Installation: Came with a clear drilling template and all necessary screws; I swapped it out of bold doors in under 20 minutes with just a Phillips head and a flathead screwdriver.The knob turns crisply, and the deadbolt slides in and out with no binding. The keyed lock locks securely and the included keys feel sturdy. Came with 3 keys for each door. If you need a reliable, easy-to-install exterior knob/deadbolt combo that looks great in matte black, this Amazon Basics set is a home-run.

The matte black finish looks sleek and modern, adding a stylish touch to my doors while matching my home’s decor perfectly.Installation was straightforward, and the quality feels solid and secure. The locks function smoothly, and the deadbolts give me extra peace of mind knowing my home is well-protected. For the price, the durability and design exceeded my expectations.Highly recommend this set if you’re looking for reliable, attractive door hardware at a great value!

Door lock
Lock functionality is good Easy to install. Not as durable and color comes off specially if you purchase the black color, it does get loose after awhile and so not as secure as it should be. Feels good but security is not recommended for the value for your money of this product

Wrong Parts and TERRIBLE quality
Holy Cow! What a complete piece of crap!I got hands on this today, and the quality is terrible. If you brush the knobs against ANYTHING, paint is coming off, and you’ll be lucky to escape without a dent in the knob.I had several wrong parts in my kit as well. I pulled up a video, thinking I was an idiot, however- what was shown in the video was a far cry from my experience. The internal mechanism of the outer door knob with the keyhole were completely upside down. Installing it properly – would have resulted in the key hole being on the top of the knob instead of the bottom. This wasn’t even the biggest issue however.The screws that came with the fasten the inner door knob were the complete wrong diameter, and I assume length as well. In the video, the technician slides the screws through the outer ring of the door knob, to line them up with the holes you are meant to screw the screws into. However, the screws received with my kit, did not slide through the hole in the outer ring. They required being screwed through, which looked to damage the screws in general. This process resulted in a ton of visual scratches and paint rubbing off on the knob.The experience might be different if your receive the correct parts, however- that was not my experience.Thankfully — the issue with my existing door knob was specific to the latch bolt, which was the only part of this kit that was any good. I swapped my latch bolt out with the one from this kit, re-installed my old knobs, and we’re all good now.Do not recommend this product in the SLIGHTEST.

Good for the money
Quality is ok, serves its purpose. Not a quality entry security lock but good for low security.

Not great quality but looks very nice
We bought a house and didn’t get a key for the back door, so I decided to buy this set because it was a third of the price of a locksmith’s service call alone. The handle on this also locks, whereas the old one didn’t, so now we have an extra layer of security. Install was incredibly easy, so I’m not sure what other reviewers were complaining about… And my only experience with changing door hardware is installing August smart locks and repeatedly fixing the same cheap handle that kept falling off my old door. The only hiccup I ran into was getting the deadbolt direction right. When you put the interior part on, you need to make sure the locking tab is turned to match the lock state of the deadbolt. (You’ll know you’ve done it wrong if you can only lock it from the outside with the key. Just take it off, flip the tab, and put it back on.)The reason I’m docking some stars is because the quality is really not great. There is a ton of play with the deadbolt’s locking tab thing and the finish scratches very easily. I knew scratching was an issue going in, so I was very careful, but still scratched it slightly while tightening the screws. It’s not very noticable, but still kind of a bummer. I can’t complain too much because the price of this thing is just unbeatable, and it does look great on my door, but I do not expect it to last for very long. I would not recommend it for a front door or any high-traffic area where it’s going to sustain a lot of wear. It has that cheap, un-smooth feeling when you turn the handle or locking mechanisms and given my experience with a previous cheap door handle falling off all the time (which leaves a big old hole in your door), I do not trust it completely for security purposes. I fortunately have several other burglary deterrents at this door (cameras, lights, etc.) but I might have returned it if I didn’t.

Jolie poignée d’une bonne grosseur jour mat. 4 clés qui ouvrent la poignée et le pêne dormant. Même barrure. On a quand même remplacé la plaque qui reçoit les barrures. Un peu mince alors on a pris des plaques industrielles.Vraiment un bon prix… je la recommande.

Cumple su cometido, mi hijo de 11 años me ayudo a instalarla y practicamente hizo todo el solo. Siguio los pasos que venian en el manual y se ayudó con videos de youtube pero la instalacion le resultó sencilla. Si un niño de 11 años lo puede hacer, cualquiera puede. Lo recomiendo para una emergencia ya que el diseño es algo neutro, con unos pesos mas puedes instalar algo mas bonito
