Lockin V7 Max Review: Smart Lock That Never Needs a Battery Change

Picture this. You come home with bags in both hands. It is raining, and your smart lock blinks a sad red light. The battery died again.

Most smart lock owners know this moment well. The Lockin V7 Max wants to end it for good. It uses a beam of light to keep itself charged, so you never swap batteries.

The lock also scans the veins in your palm, sees your face, and works as a video doorbell. It won a CES 2026 Best of Innovation award. It also costs more than many laptops.

So is it worth your money and your door? In this Lockin V7 Max review, we cover the features, the price, the install work, and the tradeoffs. Keep reading before you spend a dime.

In a Nutshell

• Battery worries end here. The V7 Max uses AuraCharge, a wireless optical charger that sends power to the lock from up to 4 meters (about 13 feet) away. You plug the transmitter into a wall outlet inside your home, and it keeps the lock topped up.
• Three ways to unlock with your body. You can use palm vein, finger vein, or 3D facial recognition. Vein scans read patterns under your skin, so wet or worn fingers are no problem.
• It doubles as a video doorbell. Two HD exterior cameras give a panoramic view. A 5 inch touchscreen sits on each side of the door, so you can see visitors from inside.
• It works with every major smart home platform. Matter support connects it to Apple Home, Google Home, Amazon Alexa, and Samsung SmartThings.
• It is a mortise lock, not a deadbolt. Most US doors will need a professional to cut a large pocket. Expect a price above $1,000 in the US.

Lockin V7 Max Review: What This Smart Lock Is All About

No products found.

The Lockin V7 Max is the flagship smart lock from Lockin. Lockin is known for bringing vein recognition to home locks. The V7 Max is its most advanced model so far.

Lockin showed the lock at CES 2026 in Las Vegas. It won the CES 2026 Innovation Awards Best of Innovation honor. Many tech outlets called it one of the best products at the show.

The big idea is simple. Smart locks run on batteries, and batteries die. Lockin solved this with AuraCharge, a charger that sends power through the air with a light beam.

The lock packs far more than a clever charger, though. It combines these features in one device:

• Triple biometrics with palm vein, finger vein, and 3D face unlock. This gives you fast, hands free entry.
• A video doorbell with two HD cameras and two touchscreens. It can replace a Ring or Nest doorbell.
• LockinAI, which spots deliveries, flags odd activity, and indexes your video clips.
• Matter support for Apple, Google, Amazon, and Samsung platforms.

Think of the V7 Max as a concept car you can actually buy. It is expensive, packed with features, and very impressive.

But it also asks a lot from your home. You need the right door, a nearby outlet, and a clear line of sight for the charger. We will cover each of these points below, so you know exactly what you are getting.

Lockin V7 Max Design and Build Quality

The V7 Max does not look like a normal smart lock. Most smart locks are square boxes with number pads. This one looks like a tall, curved door handle.

A famous name shaped this look. Hartmut Esslinger designed the V7 Max. He founded Frog Design and helped create Apple’s early “Snow White” design style.

The front panel is only 15mm thick. Lockin calls it the thinnest front panel in the industry. It gives the lock a slim, floating look on your door.

Engadget saw it in person at CES. The reviewer called it “sleek (if huge)”, with a pocket style grip. The lock is a tall black rectangle, so it makes a statement on any door.

Here is what you see on each side:

• Outside: A touchscreen, two HD cameras, and the biometric scanners. Visitors can talk with you through this panel.
• Inside: A large 5 inch touchscreen and the AuraCharge receiver panel. You see who is at the door without opening it.

The handle is built into the lock body. You do not need a separate lever or knob. This keeps the door clean and modern.

The design fits premium and modern homes best. It would look great on a glass and steel entry or a sleek wood door. On a classic colonial door, it may look out of place.

Overall, the build feels high end. It matches the price tag. Just measure your door before you fall in love with the look.

AuraCharge Wireless Power Explained

AuraCharge is the star of this lock. Lockin calls it a fourth generation power solution for smart locks. Here is how it works in plain words.

You get a small transmitter with the lock. It looks a bit like a tiny bookshelf speaker. You plug it into a wall outlet inside your home and place it within 4 meters of the door.

The transmitter sends a focused infrared light beam to a receiver on the lock. The receiver turns that light into electricity. The lock’s lithium battery stays charged all the time.

ZDNET used a helpful comparison. Solar panels are like a cup catching rain. AuraCharge is like filling that cup with a hose aimed right at it.

Is the beam safe? Yes. TÜV Rheinland and SGS certified it as eye safe. It will not hurt people, pets, or furniture that cross its path.

There are a few rules to follow, though:

• Keep a clear line of sight. If a coat rack or plant blocks the beam, charging stops.
• Stay within 4 meters. The transmitter must sit close enough to the door.
• Have an outlet nearby. Older homes may lack one near the entry.

If the beam stops, the internal battery keeps the lock running for a while. Lockin says the lock keeps working after the transmitter stops, but reports differ on how long. The Verge heard several hours, while other reviewers mention up to about a week.

In short, AuraCharge trades a battery inside the lock for a small box plugged into your wall. For most people, that is a great deal.

Triple Biometric Unlocking: Palm Vein, Finger Vein, and Face

Most smart locks use fingerprint scanners. These can fail with wet, dirty, or worn fingers. The V7 Max uses three body based methods instead.

Palm vein recognition is Lockin’s signature feature. You hold your palm near the scanner. It reads the vein pattern under your skin. You do not need to touch anything.

Finger vein recognition works the same way but uses your finger. It reads what is inside your finger, not the surface print. That makes it much harder to fake than a fingerprint.

3D facial recognition uses depth mapping, much like Face ID on an iPhone. The lock can recognize you as you walk up. This is handy when your hands are full.

Why does vein scanning matter? Your veins sit under your skin. Nobody can lift them off a glass or copy them from a photo. This gives you a real security edge.

Speed is strong too. Lockin says the palm scan can work in about 0.17 seconds. Other reports say unlocks take under half a second.

Vein scanning also helps these groups:

• Kids, because their fingerprints change as they grow.
• Older adults, whose fingerprints can fade over time.
• Workers with rough hands, like builders or gardeners.
• Anyone coming home in the rain, since water does not confuse vein scans.

One missing item stands out. The V7 Max does not list Apple Home Key support. You cannot tap your iPhone or Apple Watch to unlock it. At this price, Apple fans may miss that feature.

Top 3 Alternative for Lockin V7 Max

The V7 Max is not right for every home. It needs a mortise door and a big budget. These three alternatives fit standard US deadbolt doors and cost far less.

Lockin Veno Pro

Last update on 2026-09-25 / Affiliate links / Images from Amazon Product Advertising API

The Lockin Veno Pro is the best pick if you want Lockin’s palm vein tech at a lower price. It fits a standard deadbolt hole, so you can install it yourself.

It has palm vein and fingerprint unlock, a 2K 180 degree camera, and AI motion detection. It also offers two way talk, IR night vision, and 32GB of built in storage with no monthly fee.

This listing runs on batteries. Lockin also announced a Veno Pro Wireless version with AuraCharge, expected around $350. Check which version you are buying.

Lockly Visage Zeno Series

Last update on 2026-08-22 / Affiliate links / Images from Amazon Product Advertising API

The Lockly Visage Zeno is the closest match for hands free face unlock. It offers facial recognition, a fast AI fingerprint reader, and Apple Home Key support.

It uses two rechargeable 10,000mAh batteries and has a USB C backup port. It is IP65 rated for weather. It sells for around $349, a fraction of the V7 Max price.

Aqara Smart Lock U200

No products found.

The Aqara U200 is a top choice for renters and Apple users. It is a retrofit lock, so it fits over your current deadbolt. You keep your existing exterior hardware.

It supports Apple Home Key, fingerprint unlock, and Matter over Thread. It uses a rechargeable battery and costs around $270. It is the easiest install on this list.

Built In Video Doorbell and Dual 5 Inch Screens

The V7 Max is also a video doorbell. You may not need a separate Ring or Nest device. That means one less gadget on your porch.

The outside panel has two HD cameras. Together, they give a wide panoramic view of your entry. You can see visitors, delivery drivers, and packages on the ground.

The lock has two 5 inch touchscreens, one outside and one inside. This dual screen setup is rare in smart locks.

Here is why each screen matters:

• The inside screen shows who is at the door. You do not need to grab your phone or open the door. This is great for kids and older family members.
• The outside screen lets visitors interact with the lock. Guests and couriers can see messages and respond.

Always on power makes this possible. Video and screens use a lot of energy. Normal battery locks would drain fast. AuraCharge keeps the cameras and screens running without constant charging.

The lock can also send video to major smart home platforms. Engadget noted it can feed video to Google, Apple, Amazon, and Samsung systems.

For advanced features, you still use the Lockin app. Setup and AI tools live there.

This all in one approach saves space and money. You skip buying a doorbell, a camera, and a lock separately. You also get one app for all three jobs.

LockinAI: Smart Features That Learn Your Home

The V7 Max includes LockinAI, Lockin’s built in AI platform. Lockin says it covers 10 core scenarios. The goal is simple. Your lock should do more than open and close.

Here are the main LockinAI features:

• Theft prevention and anomaly detection. The lock watches for odd behavior at your door and alerts you.
• Smart delivery detection. It can spot a package delivery. It can even speak a set message to the driver.
• Video indexing with keyword search. You can search clips by keyword instead of scrolling through hours of footage.
• Activity monitoring per user. The lock tracks who comes and goes, and when.

Lockin also mentions family features. These include monitoring kids and older adults for safety. The company also talks about making highlight reels of family events.

Keep one point in mind. The Verge noted that some of these AI features seem to need an inside facing camera. Lockin’s early materials did not mention one. So some claims may work differently in real life.

The delivery tools are the most useful for most people. Porch theft is a real problem. A lock that spots packages and alerts you can help.

The keyword video search is a nice bonus too. Finding one clip from last Tuesday becomes quick and easy.

Overall, LockinAI adds real value. Just expect the features to improve over time through updates. Early AI tools often start simple and grow.

Smart Home Compatibility with Matter

A smart lock should work with your other devices. The V7 Max supports Matter, the universal smart home standard. This is a big plus for future proofing.

Matter lets the lock connect with these platforms:

• Apple Home for Siri control and home automations.
• Google Home for Google Assistant and Nest devices.
• Amazon Alexa for voice control and Echo Show viewing.
• Samsung SmartThings for broad device control.

You do not need a special Lockin hub. The lock has built in WiFi and Bluetooth. WiFi handles remote access. Bluetooth handles local connections near the door.

Matter is great for mixed homes. Say you use an iPhone, but your partner uses Android. Both of you can control the same lock through your preferred app.

You can build automations too. For example, the lights can turn on when the door unlocks at night. Or the lock can auto lock when everyone leaves.

There is one gap for Apple fans. As noted earlier, Apple Home Key is not listed. Matter support does not include NFC tap to unlock with an iPhone or Apple Watch.

If Home Key matters to you, the Aqara U200 or Lockly Visage Zeno may suit you better. Both support it.

For everyone else, Matter support is a strong feature. Your lock will keep working with new devices for years. That protects your large investment.

Installation: The Mortise Lock Challenge

This section may be the most important one in this review. The V7 Max is a mortise lock. It does not replace a standard deadbolt.

What does that mean? Most US doors have a round hole for a cylindrical deadbolt. A mortise lock needs a large rectangular pocket cut inside the door. Many European and Asian homes use mortise locks. Most American homes do not.

You cannot just unscrew your old Kwikset and pop this in. Here is what US buyers may face:

• Professional carpentry. A locksmith or carpenter must rout out the mortise pocket.
• Possible door replacement. Sometimes a new mortise ready door is cheaper than cutting your old one.
• Transmitter placement. You need an outlet within 13 feet of the door and a clear beam path.

Reviewer Robb Sutton put it plainly. He rated the lock 9 out of 10 for technology but 5 out of 10 for US retrofit fit. That gap says a lot.

Renters should skip this lock. It requires permanent door changes. Most landlords will not allow that.

Now for the good news. If you are building a new home or renovating, this problem shrinks. You can order mortise ready doors from the start. You can also plan an outlet in your entry for the AuraCharge transmitter.

Budget for professional installation. Lockin has offered free pro installation in some markets, like Singapore. Check what your local seller offers before you buy.

Lockin V7 Max Price and Availability

Price is a big part of any smart lock decision. The V7 Max sits at the very top of the market.

At launch, Lockin did not share a firm US price. ZDNET reported the price is expected to exceed $1,000 in the US. Robb Sutton also estimated over $1,000.

In Singapore, Lockin showrooms promoted the V7 Max at a special price of $799 in local currency. That price may include local deals and installation offers.

Here is the timeline from launch reports:

• January 2026: Lockin revealed the lock at CES 2026.
• Mid 2026: Engadget said units should ship around July or August.
• Q3 2026: ZDNET expected the lock in the US market around this time.

Plans can shift after a launch. Always check lockin.com and Amazon for the latest price and stock.

How does the price compare? The Lockly Visage Zeno costs about $349. The Aqara U200 costs about $270. A SwitchBot Lock Pro costs around $120. The V7 Max costs roughly four to five times more than many good smart locks.

Remember what you get for that money, though. You get a lock, a video doorbell, two touchscreens, AI features, and battery free power. Buying a separate premium doorbell and lock would close part of the gap.

Still, add installation costs to your budget. A mortise conversion or new door can add hundreds of dollars.

Pros and Cons of Lockin V7 Max

Every product has strong points and weak points. Here is a clear look at both sides.

Pros

• No battery swaps ever. AuraCharge keeps the lock charged all the time, so you stop worrying about dead batteries.
• Top tier biometric security. Palm vein and finger vein scans read patterns under your skin, which are very hard to fake.
• Works in rain and with worn fingers. Vein scanning handles wet hands, kids, and older adults better than fingerprint readers.
• Built in video doorbell. Two HD cameras replace a separate doorbell and cut porch clutter.
• Dual 5 inch touchscreens. You see visitors from inside without opening the door or grabbing your phone.
• Matter support. It works with Apple Home, Google Home, Alexa, and SmartThings.
• Award winning design. Hartmut Esslinger designed it, and it won a CES 2026 Best of Innovation award.

Cons

• Very high price. It is expected to cost over $1,000 in the US, plus installation.
• Mortise lock only. Most US doors need professional cutting or a full door swap.
• Transmitter needs a spot and an outlet. The box must sit within 13 feet with a clear view of the lock.
• Blocked beam stops charging. Furniture or coats in the path can interrupt power.
• No Apple Home Key. iPhone users cannot tap to unlock with NFC.
• Not for renters. Permanent door changes rule it out for most rental homes.

Who Should Buy the Lockin V7 Max

The V7 Max fits a specific type of buyer. See if you match one of these profiles.

New home builders and renovators are the best match. You can plan a mortise door from day one. You can also add an outlet in the entry for the transmitter. The install challenges almost disappear.

Luxury smart home fans will love it. If you want the newest tech and a real conversation starter, this is it. Guests will ask about your door.

Battery haters get a clear win. Some people are tired of swapping AA batteries every few months. AuraCharge fixes that for good.

Families with kids and older adults benefit from vein and face unlock. Children and seniors often struggle with fingerprint scanners. Palm vein scanning works much better for them.

Mixed platform homes gain from Matter. If one person uses Apple and another uses Google, both can control the lock.

Busy property managers may find value too. High traffic doors drain batteries fast. Always on power and durable vein scanning suit this use.

Here is who should skip it:

• Renters, because the lock needs permanent door changes.
• Budget shoppers, since strong locks exist for under $350.
• DIY retrofit fans, who want a simple Saturday install.
• Apple Home Key users, who want NFC tap to unlock.

If you fall into the skip group, look back at our top 3 alternatives. The Lockin Veno Pro gives you palm vein tech at a far lower price.

Final Verdict: Is the Lockin V7 Max Worth It?

The Lockin V7 Max is one of the most exciting smart locks ever made. It solves the biggest problem in smart locks: dead batteries. AuraCharge works like magic once you set it up.

The biometrics impress too. Palm vein, finger vein, and 3D face unlock give you fast, secure, and hands free entry. The built in video doorbell and dual screens add real daily value.

But this lock asks you to adapt your home to it. The mortise design is a real hurdle for most US doors. The transmitter needs an outlet and a clear path. The price is steep.

Here is our simple verdict:

• Buy it if you are building, renovating, or already have a mortise door, and you want the best tech available.
• Skip it if you rent, want an easy install, or need Apple Home Key.

For the right home, the V7 Max is a true glimpse of the future front door. It combines a lock, doorbell, camera, and AI helper in one sleek unit. And you never charge it.

For most other homes, a strong deadbolt lock like the Lockin Veno Pro, Lockly Visage Zeno, or Aqara U200 makes more sense. Each one gives you smart features without cutting into your door.

Our rating: 9/10 for innovation, but only a good fit for the right door. Measure your door, check your outlets, and set your budget before you buy.
