Smart locks have been around long enough that simply replacing a key with a keypad no longer feels particularly futuristic. The more interesting question is whether a smart lock can actually make getting into your home easier without adding another app, battery problem, or piece of technology you eventually stop using.
That is where Lockin takes a different approach.
Its Veno series combines traditional smart-lock features with palm-vein recognition, allowing you to unlock the door by raising your hand rather than entering a PIN or placing a finger precisely on a scanner.
After looking through Lockin’s current lineup, the palm recognition technology is certainly the feature that gets your attention, but it is not the only reason these locks are interesting.
Palm Vein Unlocking Is More Useful Than It Sounds
Fingerprint readers are convenient when they work perfectly. Anyone who has tried using one with wet, dry, dirty or damaged fingers, however, knows that the experience is not always seamless.
Lockin’s Venokey system takes a different route by identifying vein patterns beneath the skin of your palm.
On its flagship Veno Pro, Lockin states that palm recognition can unlock the door in about 0.17 seconds with 99.9% accuracy. Because the system reads internal vein information rather than simply examining the surface of your hand, it is also designed to work when hands are wet, dry or affected by everyday skin conditions.
In normal use, the benefit is straightforward: walk up, raise your palm and enter.
There is no key to find at the bottom of a bag, no PIN to remember and no need to put groceries down before opening the door.
It is one of those conveniences that may sound unnecessary until it becomes part of your daily routine.
Veno Pro Is the All-in-One Option
For homeowners who want more than keyless entry, the Veno Pro Palm Vein Recognition Video Smart Lock is the most complete model in the range.
Alongside palm-vein recognition, it supports fingerprint access, PIN codes, a mechanical backup key, app control and voice control. It also integrates with Apple Home, Amazon Alexa and Google Home through Matter.
But the biggest difference is the integrated camera.
The Veno Pro uses a 2K, 180-degree ultra-wide camera designed to provide a broad head-to-toe view around the doorway. There is also a two-way video doorbell, meaning the lock can effectively replace multiple pieces of front-door hardware rather than simply sitting next to them.
Its motion system combines radar and PIR sensing and can identify people, packages and vehicles. Lockin also includes 32GB of local video storage, with no monthly subscription required for that local storage.
That last point is easy to overlook.
A cheaper smart-home product can become surprisingly expensive once monthly cloud-storage fees are added. If you would rather pay for the hardware and avoid another recurring subscription, local storage gives the Veno Pro a meaningful advantage.
For someone upgrading an older deadbolt, doorbell and entry camera at the same time, buying one integrated device can also make considerably more sense than piecing together three separate systems.
Veno Solar Palm Solves a Common Smart-Lock Annoyance
One of the least exciting parts of owning a smart lock is remembering that it needs power.
Lockin’s Veno Solar Palm attempts to make that maintenance much less noticeable by integrating a perovskite solar charging system directly into the lock.
According to Lockin, the system can collect usable light for up to 11 hours per day and can continue charging under lower-light conditions, including cloudy weather. The idea is not that the lock suddenly becomes an off-grid solar appliance, but that regular exposure to light can reduce how often you need to think about charging it.
That makes a lot of sense for a device whose greatest strength is convenience.
The Solar Palm model still includes the features most households are likely to need: palm-vein recognition, PIN access, app control, a mechanical key and voice-assistant support.
It also has built-in Wi-Fi, remote access and Matter compatibility with major smart-home ecosystems. Auto-lock functionality can secure the door after it closes, while app notifications can alert you when the lock is used or the door needs attention.
For busy households where the front door is opened dozens of times every day, reducing battery maintenance may be more valuable than adding another flashy feature.
Veno Go Keeps Things Simpler
Not everybody needs a camera built into the front door.
If you already own a video doorbell or outdoor security camera, paying for another camera can be redundant. That is where the Veno Go becomes particularly appealing.
It focuses on the core smart-lock experience, including palm-vein entry, PIN access and connected controls, without turning the lock into a complete video-security system.
Customer feedback published on Lockin’s website repeatedly highlights the speed of palm recognition, relatively straightforward setup and the convenience of the rechargeable battery. Several owners also specifically mention choosing palm recognition after experiencing inconsistent fingerprint readers on previous devices.
For many households, this may actually be the sweet spot.
You get the feature that makes Lockin unusual without paying for technology you already have elsewhere.
That is an important consideration when choosing between smart-lock models: the most expensive option is not automatically the right one. The better choice is the one that replaces inconveniences you actually experience.
Smart Home Integration Makes the System More Flexible
Lockin also appears to understand that a smart lock should not operate as an isolated gadget.
Current Veno models support integrations with major smart-home platforms, with Matter support available across several products in the range. Depending on the model and ecosystem, that can let the lock work alongside Apple Home, Alexa, Google Home or SmartThings.
The practical possibilities are much more interesting than simply asking a voice assistant about your lock.
A connected front door can become part of broader home automations involving lights, security devices or routines associated with leaving and returning home.
For anyone already building a connected home, this makes Lockin considerably easier to justify than a proprietary smart lock that lives entirely inside its own ecosystem.
Security Has Not Been Ignored
Convenience matters, but a lock still has one fundamental job.
The Veno Pro carries BHMA Grade 2 certification and an IP65 rating for its exterior-facing hardware. Lockin lists the Pro as operating in exterior temperatures down to -22°F, making it suitable for a much wider range of climates than many indoor-oriented smart gadgets.
The Veno Solar Palm is BHMA Grade 3 certified and IP53 rated, with an exterior operating range from -22°F to 158°F. It also retains USB-C emergency power and a concealed mechanical key option, so electronic access is not the only route into the house.
Those backup options matter. Smart technology should add convenience rather than turn a dead battery or connectivity issue into a locked-door emergency.
So, Is Lockin Worth Buying?
Lockin is most compelling for people who want smart-home technology to remove everyday friction rather than simply add more screens and notifications.
Palm-vein recognition feels futuristic, but the real appeal is surprisingly ordinary: arriving home with your hands full and opening the door without searching for anything.
For maximum functionality, Veno Pro combines access control, video monitoring and a doorbell in a single device. For people who already have cameras, Veno and Veno Go provide a more focused upgrade. And for homeowners who dislike battery maintenance, Veno Solar Palm introduces an especially practical solution.
Lockin currently also advertises free shipping, a 30-day money-back guarantee and customer support on its product pages, reducing some of the uncertainty that comes with trying a less conventional type of lock.
If your current front-door routine still revolves around forgotten keys, unreliable fingerprint scans or repeatedly replacing batteries, this is the kind of upgrade you will notice every day rather than only when guests come over.
And that may be the best argument for Lockin.
It is not smart technology for the sake of looking futuristic. At its best, it simply makes one of the most repeated actions in your life—opening your own front door—faster, easier and more convenient.
If you have been putting off a smart-lock upgrade, the Veno range is well worth exploring before buying another conventional keypad model.
