Wyze is shaking things up again in the smart home space—this time with a new door lock you can open just by waving your hand. Called the Wyze Palm Lock, it uses palm vein recognition to unlock your door, and at $135 at Amazon, it’s one of the most affordable smart locks with this kind of tech.

Here’s how it works: instead of punching in a code or fumbling with keys, you simply hold your hand over the lock, and it scans the unique pattern of veins in your palm. That’s your key. No touching, no smudges—just a quick scan and you're in.

Wyze isn’t the first to try this approach—brands like Eufy, TCL, and TP-Link’s Tapo have released palm-scanning locks before—but most of those models cost way more. For example, TCL’s palm lock runs around $170, and Eufy’s version (which includes a doorbell camera) goes for nearly $400. Wyze is aiming squarely at the budget-conscious homeowner here.

And if waving at your door feels a little sci-fi for your taste, don’t worry: the Palm Lock gives you several other ways to get inside.

In addition to palm scanning, the lock has an illuminated keypad that supports up to 50 PIN codes. You can give each family member—or dog walker—their own code. Prefer the old-school route? There’s a mechanical keyhole, tucked behind a sliding cover. And of course, you can unlock the door remotely using the Wyze app, or even straight from your Wyze video doorbell’s live feed.

To keep nosy neighbors from stealing your code, the keypad has what Wyze calls “anti-peep” protection. You can add extra numbers before or after your real code, and as long as the correct sequence is there, the door will still open. Handy if someone’s looking over your shoulder.

One of the smarter features here is the built-in gyroscope, which can sense the angle and movement of your door. That lets the Palm Lock know when the door is closed, so it can automatically lock itself. That way, you’re less likely to accidentally leave your home unsecured—or worse, slam the door with the deadbolt extended, which can damage your door frame.

If someone repeatedly tries to guess the code (or just messes with the lock), it’ll sound an alarm. Same goes if the door is left ajar too long—it’ll give you a little audible nudge with a chirp to remind you.

Battery anxiety? Wyze has that covered. The Palm Lock runs on a rechargeable lithium-ion battery that should last up to six months on a single charge. But it also includes a backup battery that kicks in if the main one dies, giving you about two more weeks of use. And in the unlikely event that both batteries are flat, there’s a USB-C port on the bottom of the lock—you can plug in a power bank and unlock the door with your access code.

To help stretch battery life, Wyze uses millimeter wave radar (yep, the same kind used in self-driving cars) to detect when someone is approaching the door. The lock stays in low-power mode until you’re near, then wakes up just in time to greet you.

The Palm Lock plays nicely with smart assistants like Amazon Alexa and Google Assistant, so you can control it with your voice. You can also set up automations through Wyze Rules—like locking the door automatically at night or when you leave home.

While the Palm Lock isn’t completely waterproof, it does have an IP53 rating, which means it can handle some dust and splashes—like light rain or water from a hose. It’s also earned BHMA certification, which means it’s been tested to withstand daily wear-and-tear, including slamming, twisting, and repeated use.

The Wyze Palm Lock takes a futuristic idea—unlocking your door with just your hand—and makes it approachable, practical, and most importantly, affordable. Whether you’re into hands-free access or just want a smart lock with multiple entry options and solid backup features, this might be worth considering.

The lock is available now for $135 on Amazon.
