No Keys? No Problem

Losing your keys is the worst. But what if your hand could be your key? The Eufy FamiLock S3 Max makes that real with palm recognition tech that unlocks your door in seconds. You don’t have to fumble in your bag, punch in a code, or carry anything.

Your palm is all it needs. It’s like having a personal doorman who always knows you. It’s safe, fast, and even works if your hands are full. Just walk up, hold out your hand, and walk in. No more digging for keys in the rain.

What Makes Your Palm So Unique?

Inside your hand are tiny blood vessels that form a one-of-a-kind pattern. This pattern is completely yours, kind of like a fingerprint, but even more secure. Palm vein scanning uses light to read these veins, then matches them to your profile.

No two people have the same one, not even twins. That makes it super hard to fake. And because the scanner looks beneath your skin, dirt, sweat, or cuts won’t affect it. Your palm is a secret password built right into you, and the lock can recognize it instantly.

Just Hover, No Touch Needed

One of the coolest parts? You don’t even have to touch anything. Just hover your hand in front of the scanner. It recognizes your unique vein pattern without contact, unlocking the door in under a second.

No pushing buttons or placing your finger just right. It’s not just about convenience, it’s more hygienic too. This touch-free setup helps reduce germs from being passed around. It’s fast, clean, and feels like something out of a sci-fi movie, but it’s available for your front door right now.

Smart Security in a Single Device

The Eufy FamiLock S3 Max is more than just a smart lock. It’s also a powerful video doorbell with smart features built in. It has a 2K camera that shows you who’s outside, alerts you when someone approaches, and lets you talk to visitors straight from your phone.

You don’t need two devices anymore, this one covers it all. That saves you money and keeps your entryway neat. From security to convenience, it’s designed to give you more control over your front door than ever before.

See Everything, Not Just Faces

The built-in camera doesn’t just catch faces, it captures a full-body view. Thanks to its 140-degree wide-angle lens, you’ll see from the visitor’s head to the packages at their feet. That means you’ll know exactly what’s happening on your doorstep at all times.

No blind spots, no surprises. It’s great for keeping track of deliveries, checking who’s knocking, or spotting someone lingering nearby. You’ll never have to wonder what’s happening outside your front door again.

Built-In AI Watches Out for You

The smart AI in the FamiLock S3 Max does more than record; it actually thinks. It can tell the difference between a car passing by and someone standing near your door.

If someone’s hanging around too long, you’ll get an alert, even if they don’t ring the bell. This helps you catch suspicious behavior before anything happens. And because it learns from activity patterns, false alarms are rare. It’s like having a digital guard dog that never sleeps.

Local or Cloud? You Decide

When the lock records video, you get to decide where it’s saved. Want full privacy? Save everything locally with an Eufy HomeBase 3 drive. Prefer convenience? Store it in the cloud and access it from anywhere with a subscription.

It’s about giving you control. Some folks like keeping data close to home, while others enjoy checking footage while on vacation. Either way, you’re covered. Your footage stays secure, and you always have access to your front door history.

Weatherproof and Ready for Life

Rain, snow, heat, or dust, the FamiLock S3 Max is built to last. It’s designed to keep working through tough conditions. The palm scanner still works when your hand is sweaty, dirty, or cold.

No need to dry off or clean up before using it. The lock’s tough shell protects it from the elements, so you don’t have to worry about wear and tear. It’s made for real-life homes and busy households, not just sunny days.

Power That Keeps You Going

Smart locks need power, but this one keeps running longer than most. It’s packed with a 15,000mAh battery that lasts up to six months on a charge. And just in case, it has four AAA battery backups to keep your door working.

No more worrying about being locked out because of a dead battery. It gives you time, warnings, and options. It’s smart power for a smart lock, so you’re never stuck on the wrong side of the door.

Works for Everyone in the Family

Grandparents, kids, guests, everyone can use this lock easily. There’s no need to remember codes or carry keys. Just register their palms, and they’re good to go.

No confusion, no lockouts. It’s especially handy for kids who might lose keys or for older adults who find tiny keypads hard to see. Everyone deserves secure access to a home without the hassle. This lock makes sure of that.

Cleaner Than Fingerprints

Fingerprint scanners are popular, but they’re not always clean. Multiple people touching the same surface can spread germs fast. Palm vein recognition doesn’t need contact.

Your hand hovers, the scan completes, and that’s it. It’s perfect for households with kids or frequent visitors. No mess, no worries. Plus, you won’t have to wipe down your lock every time someone uses it.

More Secure Than Most Locks

Some locks can be tricked with fake fingerprints or copied keys. Not this one. Palm vein patterns are nearly impossible to copy. They’re hidden under your skin, and only you have your exact layout.

It’s way more secure than using a PIN or a regular fingerprint reader. If you want a lock that actually protects your home from the inside out, this is the kind of upgrade you need.
