Kadonio 408 Smart Door Lock with Fingerprint, APP Control, and Key: 3-IN-1 Fingerprint door lock: Fingerprint +APP Control+ Physical Key
Available Options

Say goodbye to fumbling for keys—Kadonio Smart Door Lock is here to make your life easier. With a 99% fingerprint recognition rate, it’s like magic: just a touch and you’re in, all in under a second. And hey, it remembers up to 30 fingerprints, so the whole family (or your entire entourage) can come and go without a hitch.
Worried about installation? Don’t be. This bad boy fits most US standard doors like a glove—backsets of 2-3/8″ or 2-1/8″, door thickness from 1-3/8'' to 2-1/8''. No wires, no drills, and it doesn’t care if your door swings left or right. It’s the Swiss Army knife of door locks.
Control freak? You’ll love the Smart APP Control. Hand out temporary passwords like candy, lock or unlock your door from your couch, and never worry about lost keys again. Whether it’s your home, a hotel, or even your secret lair, this lock’s got you covered.
Battery dying? The lock’ll warn you (how thoughtful). And if you’re really in a pinch, there’s a USB port for emergency charging. Just pop in 4 AAA batteries (not included, because let’s be honest, who reads the fine print?), and you’re golden.
And because we’re not monsters, there’s a 30-day money-back guarantee, a 12-month warranty, and tech support for life. Sleep tight knowing we’ve got your back.
