Does it job. Lock works great. Easy to install. Very strong material. The look is ok for the price . ### ⭐⭐⭐⭐⭐ As advertised! *by D***L on November 11, 2024* The media could not be loaded. Very pleased! I picked this one because I saw it has a tiny the little white piece and thought it was just what we needed because the hole is all messed up and making it a loose fit. So I used it and it made it a perfect fit! Installation was easy and fast. The key functionality is smooth. Price is very affordable. Color matched my dead bolt lock! Lock functionality is perfect 🤩 it is very study and it came with three keys! I was shocked to see how nice it is for the price. I feel like it won’t be as easy to break in with this lock! I definitely recommend this set up for anyone looking for a knob that locks! ### ⭐⭐⭐⭐⭐ Amazing quality *by J***E on May 3, 2025* I have bought many locks and none as easy and fast to install, I loved it and maybe 5 minutes to install.I highly recommend this one. ## Frequently Bought Together - DSJJBLL Doorknob with Key Matte Black Round Ball Door Knob Passage Door Privacy Locking Interior/Exterior Door Knob/Berlin Series Lock for Room Door - Amazon Basics Exterior Door Knob With Keyed Lock and Deadbolt, Coastal, Matte Black - TEEHO TE001 Keyless Entry Door Lock with Keypad - Smart Deadbolt Lock for Front Door with 2 Keys - Auto Lock - Easy Installation - Matte Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/519613854-doorknob-with-key-matte-black-round-ball-door-knob-exterior](https://www.desertcart.us/products/519613854-doorknob-with-key-matte-black-round-ball-door-knob-exterior) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-11-10*
