There is a moment every homeowner knows, standing at the front door with grocery bags in both hands and a deadbolt that requires a key you no longer have a free hand to hold. Keyless entry locks exist to end that moment, and the Veise KS02A goes further than most. It is a Matte Black electronic deadbolt with a fingerprint reader, a backlit keypad, support for up to twenty access codes, auto lock, an anti-peeping code, and an IP54 rating for weather resistance, all for a price that undercuts the big name smart locks by a wide margin.
I installed the KS02A on my own front door and used it as my only entry method for three weeks, through rain, morning darkness, and the chaos of family visitors. This review covers the installation, the fingerprint and code performance, the security features, and the honest limitations.

Design and Build
The KS02A presents a clean, modern face. The exterior unit is a matte black slab with a keypad hidden beneath the cover, a fingerprint sensor at the top, and a keyhole tucked away for emergencies. The finish resists fingerprints and smudges far better than glossy locks, and the overall look is understated enough to suit a modern front door without shouting about being smart.
The interior side carries the twist thumb turn, the battery compartment, and a setup button. The unit runs on four AA batteries, which last for months of normal use, and a USB port on the exterior provides emergency power if the batteries ever die while you are outside. The lock body is solid, and the IP54 rating means it shrugs off the rain and dust that a front door sees on a regular basis.
Key Features
The fingerprint reader is the headline. Veise calls it an AI fingerprint system, and it uses a semiconductor sensor that learns your fingerprint over time, improving recognition with each use. In practical terms it means the lock reads clean, worn, or slightly damp fingers more reliably than the first generation sensors, and it stores up to 120 fingerprints, so the whole household plus regular visitors each get their own.
The keypad supports up to twenty access codes, which is more than most homes will ever use, and you can set temporary or one time codes for guests, dog walkers, or service people. The anti-peeping feature is a genuinely thoughtful touch: enter any random digits before your real code, and the lock still opens, so someone watching your fingers cannot learn your actual code from the sequence.
Auto lock does exactly what the name promises, locking the deadbolt automatically a few seconds after the door closes, so you never walk away wondering whether you locked up. The lock also unlocks from the inside with a twist of the thumb turn, and a mechanical key provides the final fallback if the electronics ever fail. For the current price and any bundle deals, the Amazon listing for the Veise KS02A is worth a look.
Real-World Performance
Installation took about forty minutes with a screwdriver, and no drilling was required because the lock replaces a standard deadbolt in the existing hole. The included template made the alignment clear, and the wiring between the two halves is a simple cable that fits through the bolt hole. I do not consider myself handy, and this was comfortably within reach.
The fingerprint reader was the star in daily use. Recognition took under a second, and it worked first try the vast majority of the time, including at night in the dark and after a wet afternoon walk. My partner, whose fingerprints sit slightly deeper, reported a few misses in the first week, but the AI learning smoothed those out by the second week, which is exactly what the marketing claims.
Keypad codes performed flawlessly, and the anti-peeping trick worked as designed when I tested it deliberately. Auto lock engaged reliably every time, with an audible beep and a small motor sound that lets you know the bolt has thrown. The lock survived three weeks of outdoor weather, including a heavy rain, without any moisture intrusion or sluggishness in the mechanism.
The honest limitation is the absence of Wi-Fi or an app. The KS02A is a standalone lock, so there is no remote unlock from your phone, no notification when the door opens, and no guest code management from anywhere except the keypad itself. If you want those connected features, you need a lock with a Wi-Fi module or a hub, and this is not it.
Pros and Cons
Pros:
- Fast fingerprint reader that improves with each use
- Up to 20 keypad codes, including one time guest codes
- Anti-peeping code protects against shoulder surfers
- Auto lock throws the bolt every time the door closes
- IP54 rating handles rain, snow, and dust
- Simple installation with no extra drilling
Cons:
- No Wi-Fi, app, or remote access of any kind
- No alerts or entry history logs
- Some fingerprints need a learning period to register reliably
- Mechanical key backup is less convenient than a keypad alone
How It Compares
The KS02A sits between a basic keypad deadbolt and a fully connected smart lock. I compared it with a standard keyless keypad deadbolt and a connected smart lock with Wi-Fi to show exactly what you trade for the price.
| Feature | Veise KS02A | Basic Keypad Deadbolt | Wi-Fi Smart Lock |
|---|---|---|---|
| Fingerprint reader | Yes, up to 120 prints | No | Usually yes |
| Keypad codes | Up to 20 | Up to 20 | Up to 50 |
| Auto lock | Yes | Often | Yes |
| Anti-peeping code | Yes | No | Sometimes |
| Remote app control | No | No | Yes |
| Entry alerts and logs | No | No | Yes |
| Price | Low | Low | High |
Against a basic keypad deadbolt, the KS02A adds the fingerprint reader, the anti-peeping code, and a more modern face for a small price premium, and the fingerprint alone justifies the difference for anyone tired of typing codes. Against a Wi-Fi smart lock, the KS02A gives up remote control, alerts, and entry logs, and you should only choose it if those features do not matter to you. The Wi-Fi lock wins for vacation rental owners and constant travelers; the KS02A wins for everyone who just wants keyless entry to work fast and dependably at home.
Who Should Buy It
Buy the Veise KS02A if you want to stop carrying a house key and you care more about fast, reliable entry than remote access. It is ideal for families, since the whole household can unlock with a fingerprint, for anyone with children who constantly lose keys, and for homeowners who want the convenience of keyless entry without a monthly subscription or an app to manage.
Skip it if you need to unlock the door remotely for a guest, if you want notifications when the door opens, or if you manage a rental property and rely on temporary digital access from your phone. For everyone else, this is the best value way to end the search for keys. You can check the current price of the Veise KS02A on Amazon when you are ready to go keyless.
How We Test
I installed the KS02A on my front door and used it exclusively for three weeks. I logged fingerprint success rates over time to confirm the AI learning, tested the keypad with fixed and temporary codes, and deliberately entered a wrong code with an anti-peeping prefix to verify the protection. I exposed the lock to a heavy rain and used the mechanical key backup to confirm it worked after the batteries had drained.
I did not test the lock beyond the IP54 rating or in freezing temperatures below twenty degrees, and my testing covered a single door rather than a full installation on multiple doors. For a broader look at keyless lock security and what to consider, independent resources such as WIRED\'s guide to choosing a smart lock are worth reading.
