Omlepai CS9b Smart Door Knob with Keypad Keyless Entry: Multiple ways to unlock: fingerprint, password, mechanical keys, App control
🔒 Say goodbye to fumbling for keys—the Smart Door Knob is here to upgrade your home security with keyless entry that's as easy as a tap, a code, or even your fingerprint (because who remembers passwords these days?). And with that spacious 160*160DIP fingerprint sensor, it's like rolling out the red carpet for your fingers—fast and fuss-free access every time.
🔄 Worried about forgetting to lock up? The auto-lock feature has your back, snapping shut after 5 seconds. Plus, the anti-lock function means only the big shots (aka admins) can open it from the inside. It's like having a bouncer for your door, minus the velvet rope.
🛠️ No need to call in the handyman—this bad boy fits most US standard doors (1-3/8'' to 2-1/8'' thick) without any wiring or drilling. Whether it's your bedroom, office, or that Airbnb you're secretly running, installation is a breeze.
🔋 Running on 4 AAA batteries (sold separately, because life's full of surprises), it keeps going for 10-12 months. And if the batteries are running low? It'll yell at you (figuratively) and there's even a USB port for emergency juice—because security shouldn't take a coffee break.
📱 Control your door from the couch, the office, or even the beach with the Tuya Smart App. Lock, unlock, share E-codes, or play detective with access logs—all without WiFi or fees. It's like having a remote control for your door, and who doesn't want that?

Smart Door Knob with Keypad Keyless Entry
Katherine L.

Before getting this, I was always fumbling with keys, especially when coming back from trips with luggage, and it was a real pain. Now, with this smart knob, I can just tap my finger or use a code, and it's much smoother. The packaging is fine, nothing fancy but adequate. However, I've noticed that after a few weeks of use, it doesn't always respond as reliably as I'd hoped. For instance, in cold weather, the performance dips a bit, which worries me for winter. The remote features are handy, but without WiFi, they're not as useful as advertised. Overall, it's an upgrade, but not without its flaws. I'd recommend it with reservations, as it does improve daily convenience but falls short on some promises.
- Pros: From what I feel, the keyless entry is very convenient, especially with the fingerprint option, which works quickly and accurately. I liked that it locks automatically after a short time, adding a layer of security without me having to think about it. The installation was straightforward and didn't require any special tools or wiring, fitting my door perfectly. Being able to control it remotely through the app is a nice touch, allowing me to manage access even when I'm not home, which is great for my travel schedule.
- Cons: I'm disappointed that the batteries aren't included, which was an unexpected hassle. The app functionality is limited without an internet connection, which feels restrictive. Sometimes, the fingerprint sensor doesn't recognize my print on the first try, which can be frustrating. The build quality seems a bit cheap for the price, and I'm skeptical about its long-term durability, especially in harsh weather conditions here in Boston.
