Saulex DB02 Smart Fingerprint Door Lock: 5-in-1 unlocking methods: fingerprint, APP, NFC card, password, mechanical key
Ever fumbled for your keys in the dark? The Saulex DB02 Smart Fingerprint Door Lock is here to save your sanity—and your fingers—with ultimate security and convenience. It's not just about fingerprints (though those are pretty cool); you've got options. APP, NFC card, password, or even the old-school mechanical key (because sometimes, tech needs a backup plan). And with WiFi, you can check on your door from your couch or Timbuktu—real-time alerts mean you're always in the know.
Looks matter, right? This lock isn't just tough (thanks, zinc alloy), it's also easy on the eyes with a design that screams modern. The fingerprint spot? Right where you'd naturally reach—no awkward hand yoga required. And the Saulex Home APP is like having a remote control for your door. Lock it, unlock it, set up fingerprints, or hand out temporary passwords like you're running a high-tech hotel.
Worried about installation? Don't be. If you can handle a screwdriver, you're golden—10 minutes, tops, and it fits pretty much any U.S. standard door. And for those who think manuals are hieroglyphics, the voice prompt is like having a friendly guide walking you through every step. Easy peasy.

Smart Fingerprint Door Lock

As someone who values both security and convenience this lock has been an acquired taste for me I installed it myself in about ten minutes with just a screwdriver and it fit my standard door without any issues which was a relief The multiple ways to unlock like using a card or a code are great for when I have guests over and I can set temporary access which feels very handy The real time alerts keep me informed but the occasional glitches with the app or fingerprint reader can be a downer making me wish for more consistency Overall it does what it promises but with some minor hiccups that keep it from being perfect I'd recommend it with a note to be patient with the tech aspects :)
- Pros: I really appreciate how easy it is to unlock the door with just a touch it feels incredibly natural and saves me from digging for keys especially when my hands are full from grocery shopping The ability to check and control the lock from my phone is a lifesaver for my busy schedule and I love that it works with the app to give me alerts if something happens The design looks modern and sleek on my door and the voice guidance made setting it up a breeze no need to stress over complicated instructions
- Cons: Most likely the connection to my home network can be a bit unreliable at times which is frustrating when I need to use the app features and it doesnt always recognize my fingerprint perfectly especially if my hands are wet or dirty from cooking which happens more often than Id like The materials feel sturdy but I worry about long term durability with all the daily use
