Walk into any hardware store or search online, and you'll find dozens of smart locks competing for your attention with overlapping feature lists, vague marketing claims, and specifications that are hard to compare apples-to-apples. Most buyers end up choosing based on price alone — and then discover too late that the lock doesn't fit their door, requires a monthly subscription, or doesn't support the one unlock method that actually matters to their family.

This guide cuts through the noise. Whether you're replacing a front door deadbolt, securing a short-term rental property, or outfitting multiple doors in your home, these are the eight specifications that actually determine whether a smart lock will serve you well — and what each one means in plain language. Knowing them before you shop saves money, frustration, and a wasted afternoon with a screwdriver in your hand.

Spec 1: Security Certification (ANSI/BHMA Grade)

The most overlooked spec on any lock listing is the ANSI/BHMA grade, yet it's the one that directly measures how well the lock holds up physically. The American National Standards Institute (ANSI) and the Builders Hardware Manufacturers Association (BHMA) jointly test locks for cycle durability, impact resistance, and operational consistency. Grades run from 1 to 3, where Grade 1 carries the most demanding test requirements and Grade 3 is the entry-level residential standard.

For most residential exterior doors — front doors, back doors, side entry — ANSI/BHMA Grade 3 is the appropriate standard. Grades 1 and 2 are primarily designed for high-traffic commercial environments like office buildings and hotels, where a lock might cycle tens of thousands of times more per year than a household door ever would. A Grade 3 certification on a residential smart lock means the mechanism has passed standardized testing for the conditions it will actually encounter at home. All Veise smart locks carry ANSI/BHMA Grade 3 certification, which is the recognized residential standard. When shopping, always look for a stated grade — any lock that doesn't list one gives you no independent verification of its durability.

Spec 2: Door Compatibility

Before you evaluate a single feature, confirm whether a lock can physically fit your door. This sounds obvious, but skipping this check is the number one reason smart lock installs go wrong. The two factors that determine compatibility are door material and door thickness.

Door material matters because most residential smart locks are engineered specifically for wood doors. Metal, fiberglass, storm, and sliding doors require different hardware mounting systems and have different structural properties — wireless signals can degrade against dense metal surfaces, and non-wood materials won't accept standard screw anchors the same way. If your front door is anything other than wood, confirm explicitly with the manufacturer before ordering. All Veise locks are rated for wood doors only and are not compatible with fiberglass, metal, storm, or sliding doors.

Door thickness is the other key measurement. Standard residential wood doors typically measure between 1-3/8" and 2" thick, and the lock's interior and exterior panels need to bridge that gap correctly. A door that's too thin won't provide enough structural support for the mounting hardware; a door that's too thick means the connecting components won't reach each other. Measure the edge of your door with a tape measure before you browse listings. Veise locks are designed for the 1-3/8" to 2" standard range — if your door falls within that window, you're good to go.

One more item to verify: whether you have the authority to replace the hardware. Unlike retrofit locks that sit on top of your existing deadbolt, most full smart lock replacements (including all Veise models) require removing and replacing the existing lock hardware entirely. This is a straightforward improvement for homeowners, but it does mean you need to own the property or have explicit permission from the property owner before proceeding.

Spec 3: Lock Type and Form Factor

Smart locks are not one-size-fits-all in form. The lock type determines where it can be used, what security function it performs, and what your door will look like after installation. Understanding the four main categories saves you from buying the wrong product for your door.

• Keypad Deadbolt: The standard choice for exterior doors that need a primary security lock. A deadbolt extends a solid metal bolt into the door frame, which gives it extra resistance to forced entry compared with a spring latch. Keypad deadbolts combine that physical security with code-based access, and the KS02 series adds fingerprint capability. This is the most common smart lock form factor for front and back doors.
• Keypad Latch Lock: An integrated handle-and-lock unit where the handle and locking mechanism are built into one body. Keypad latch locks are commonly used on interior doors, side entries, garage access doors, office doors, and similar applications — any door where daily code access is the priority and you may also have a separate deadbolt providing primary security. The two current Veise SKUs differ by handle type: the KS03 features an integrated top knob, while the KS04 has an integrated top lever.
• Smart Lock w/ Gateway 1/2: A deadbolt-style lock that pairs with a small gateway device to deliver full remote app control. This category bridges the gap between a simple keypad lock and a fully connected Wi-Fi lock — giving you app access, entry history, and voice assistant compatibility without requiring the lock itself to maintain a constant Wi-Fi connection. Veise offers two gateway generations: Smart Locks w/ G1 and Smart Locks w/ G2, each with distinct features covered in the connectivity section below.
• Wi-Fi Smart Lock: A deadbolt-style lock with built-in Wi-Fi connectivity — no separate gateway needed. Wi-Fi smart locks connect directly to your home's 2.4GHz router and offer full remote control, voice assistant integration, and real-time alerts right out of the box. Veise offers two Wi-Fi series: the Touchscreen Wi-Fi Smart Lock (VE027 Series) and the Push-Button Wi-Fi Smart Lock (VE012W Series).

A practical note on exterior door security: deadbolts (keypad or smart) are typically the right fit for exterior doors where primary security is the goal. Keypad latch locks are often a good fit for interior and secondary doors, though they're also used on entry doors when paired with a separate deadbolt — the latch handles daily code-based access while the deadbolt handles the primary lock function. The right form factor depends on your specific door and how it fits into your home's overall security layout.

Spec 4: Unlock Methods

The number and type of ways you can unlock a door is one of the most practically significant specs for daily life — and also one of the most misleadingly marketed. Brands often advertise a total number of unlock methods without clarifying that those methods vary by model. A more useful approach is to understand what each lock category supports, so you can match it to how your household actually operates.

Here's how Veise's four categories break down by unlock method:

• Keypad Deadbolt: Keypad code and physical key backup on all models. The KS02 series adds fingerprint. The non-fingerprint line includes the RZ and KS01 series. Key fob is not supported in this category.
• Keypad Latch Lock: Keypad code and physical key only. No fingerprint, no app, no key fob — a focused, straightforward access solution with currently two SKUs.
• Smart Lock w/ Gateway 1/2: Keypad code, remote app control via the paired gateway, voice assistant, key fob, and physical key are available across all models. Many models also include fingerprint. This category offers the broadest combination of everyday and backup access methods.
• Wi-Fi Smart Lock: Remote app, keypad code, voice control via built-in Wi-Fi (Alexa and Google Assistant), physical key backup on all models, fingerprint included on all models, and key fob on the VE027 series (not on the VE012W series). This is the right choice for families who want to monitor entry history remotely and receive real-time push alerts.

On fingerprint recognition: Veise's fingerprint-equipped models use an AI chip for on-device processing, with a scan recognition speed of less than 0.3 seconds. Enrollment captures the finger eight times to build a reliable template across different angles and pressure levels. Fingerprint data is processed and stored locally on the lock itself — no cloud account required, no data leaving the device. This is a meaningful privacy and reliability advantage over systems that send biometric data off-site for processing.

One important clarification: voice control works differently depending on the lock type. Wi-Fi smart locks support Alexa and Google Assistant directly through their built-in Wi-Fi radio. Smart Locks w/ Gateway 1 or Gateway 2 also support voice commands, but only when the paired gateway is in place and connected — the gateway handles the bridge between the lock and your voice assistant. Do not assume all smart locks automatically work with Alexa or Google without verifying the connectivity requirements for that specific model.

Spec 5: Connectivity Type

The connectivity spec is where the most confusion happens when comparing smart locks, and where the choice has the biggest impact on your day-to-day experience. There are two meaningful connectivity paths for remote app control: built-in Wi-Fi and gateway-paired. It's worth being clear that a Keypad Deadbolt or Keypad Latch lock cannot be upgraded to remote access by adding a gateway — the lock itself must be designed for connectivity from the factory.

Built-in Wi-Fi locks connect directly to your home's 2.4GHz router. There's no additional hardware to buy, no gateway to position near the door. Open the app, and you have full remote control from anywhere with an Internet connection. The lock body houses its own Wi-Fi radio, so a robust battery setup matters. Veise's Wi-Fi smart locks are built with an 8 AA battery design instead of the more common 4 AA setup, delivering stronger signal stability and a longer-lasting power reserve. If Wi-Fi goes down but you're within short-range wireless distance, app control continues to work locally. Only long-distance remote features — off-site locking, alerts when you're away from home — require live Internet.

Gateway-paired smart locks work by communicating wirelessly with a small gateway device you plug into a wall outlet within wireless range of the lock and connected to your home network. The gateway handles the Internet connection on the lock's behalf, so the lock itself doesn't run a Wi-Fi radio. Veise's two gateway lines each have distinct strengths:

• Smart Lock w/ G1 (VE017 series): The entire G1 line is one series — the VE017. Every G1 model ships with fingerprint, multilingual voice prompts (English, Spanish, and French), and a USB-C emergency power port as standard features across all SKUs. G1 line uses a Veise-developed first-party app. For households with multilingual family members or non-English-speaking guests, G1 line's three-language voice prompts are a concrete advantage. This is the strongest all-in-one connected pick in the Veise lineup.
• Smart Lock w/ G2 (VE0/RZ0 series): G2 line is notable for two features unique to this line — Apple Watch unlock and web portal control. G2 line offers more SKU variety than G1 line, with both fingerprint and non-fingerprint options, in standalone or handle-set bundle configurations. Voice prompts are English only. G2 line is the right recommendation when Apple Watch access matters, or when a budget-friendly connected option without fingerprint is needed.

Neither Veise gateway line uses Zigbee or Z-Wave — a useful detail if you're trying to simplify your home's connectivity protocols and prefer to stay on Wi-Fi-based infrastructure.

Spec 6: Battery Design and Emergency Backup

Battery design is one of the most practically important specs on any smart lock and one of the least discussed. The questions that actually matter are: how long will it last under real use, what happens when it runs low, and what is the emergency backup when it dies completely?

Veise's Wi-Fi smart locks use 8 AA batteries rather than the 4 AA configuration found in many competing models. The higher cell count supports a stronger signal, more stable connectivity, and a longer-lasting power reserve — particularly important for a Wi-Fi-connected lock where the radio is always active. All Veise locks, across every category, use AA/LR6 alkaline batteries available at any hardware or grocery store (not included in the box). There's no proprietary battery pack to source or recharge.

The emergency power backup spec is one that often surprises buyers who only discover they need it after a battery dies. On every model in two Veise series — the VE017 series (Smart Lock w/ G1) and the VE027 series (Touchscreen Wi-Fi Smart Lock) — a USB-C emergency power port is built into the exterior assembly. If the battery reaches zero, you connect a charged USB-C power bank to the port to supply power, and enter your code to unlock. Note that this USB-C emergency port is specific to these two series; it is not a universal feature across all Veise locks. For buyers who specifically want this safety net, the VE017 or VE027 series are the ones to choose. Every Veise lock, in every category, also includes a physical key as backup.

Spec 7: Auto Lock and Access Control Features

Auto lock is the feature that closes the gap between "I think I locked the door" and knowing for certain that it's locked. When enabled, the lock automatically re-engages after a configurable delay following any unlock event. Veise locks support auto lock with a configurable interval between 10 and 99 seconds on Keypad Deadbolt and Keypad Latch locks, and 10 to 180 seconds on connected models — short enough to secure the door moments after entry, and long enough to accommodate moving in groceries or letting a child through before the lock re-engages.

Auto lock is a universal feature across the entire Veise lineup, so it's not a differentiator between models — it's a baseline expectation. What does differentiate models in the connected categories (Smart Lock w/ Gateway 1/2 and Wi-Fi Smart Lock) is the broader set of access control features that come with app connectivity:

• Entry history logs: Every lock and unlock event is timestamped and stored, accessible through the app. Owners managing a rental property can see exactly when the door was accessed. Families with school-age kids can confirm arrival times without a phone call.
• Unique access codes per person: Rather than sharing a single household code, you can assign individual codes to each person — kids, a dog walker, a house cleaner, a contractor. Individual codes are easy to revoke without changing everyone else's access.
• Scheduled codes: Recurring and Duration codes that expire on their own (on Smart Lock w/ G1 and Wi-Fi smart locks; One-Time codes work on every Veise lock) are especially useful for short-term rental properties or one-time service visits. The guest gets convenient keyless entry; you don't have to track down a physical key afterward.
• Push notifications: Real-time alerts for every lock event, sent to your phone without needing to check the app manually.

For families with children, a Wi-Fi smart lock or a gateway-paired smart lock is worth the upgrade specifically for these features. The combination of entry history and push notifications replaces the anxious "did they get home?" text with quiet confidence.

Spec 8: Installation Requirements

A smart lock that takes a professional visit to install adds cost and delays to what should be a simple home upgrade. The installation spec covers three things: what tools are required, how long it takes, and whether the lock is a full replacement or a retrofit overlay.

Full replacement vs. retrofit: Some brands sell smart locks that overlay on top of your existing interior deadbolt hardware, leaving the exterior keyhole and thumb-turn visible. This approach preserves your existing lock and works for renters who can't modify the door. Veise takes the opposite approach — all Veise locks are full replacements, removing both the interior and exterior hardware and installing a complete new lock. This gives you a cleaner, more integrated result with no legacy hardware visible, but it does mean you need to own or have authority over the door before proceeding.

Tools and time: Every Veise smart lock is designed to install in about 15 minutes using only a screwdriver. No wiring, no professional help, no special tools. The Veise lineup is built around what the brand calls the Effortless Home Improvement™ Experience — the idea that upgrading your home should simplify your life rather than create a new project. If a lock requires specialized tools, wall wiring, or a professional electrician, that's a hidden cost worth factoring into your comparison before you commit.

Gateway placement is one additional installation consideration for Smart Lock w/ G1 or G2 buyers. The gateway plugs into a standard wall outlet; it should sit within wireless range of the lock while still reaching your home network — don't default to the outlet next to the router if that's far from the door. This is typically easy in most homes but worth a quick mental walkthrough before purchasing.

Putting It All Together

These eight specs — security certification, door compatibility, lock type, unlock methods, connectivity, battery design, auto lock and access control, and installation requirements — form a complete framework for evaluating any smart lock on the market. When you apply them together, the right choice becomes clear quickly.

For a family home where parents want to monitor when children arrive after school, a Wi-Fi smart lock or a gateway-paired Smart Lock w/ G1 delivers the entry history and real-time push alerts that make that possible. For a landlord managing a vacation cabin or short-term rental, scheduled codes and remote app control are the priority features, which points toward a Smart Lock w/ G1 or a Wi-Fi smart lock. For a homeowner who simply wants reliable keyless entry on a side door or garage entrance without the complexity of app connectivity, a keypad deadbolt or keypad latch lock covers the need cleanly and affordably.

Veise offers the full range — keypad deadbolts, keypad latch locks, Smart Locks w/ G1, Smart Locks w/ G2, and Wi-Fi smart locks — priced from $30 to $180 with no subscription required and no lock-in to a cloud service. Every model is designed to install in 15 minutes with a screwdriver, verifies fingerprints and access codes on the lock itself, and ships from a brand backed by 38 years of lock industry expertise and 711 patents — the world's largest smart lock patent portfolio. Easy from Day One.

Frequently Asked Questions

What ANSI grade do I need for a residential smart lock?

ANSI/BHMA Grade 3 is the recognized standard for residential doors. Grades 1 and 2 are designed for high-traffic commercial settings, not a higher residential quality tier. For a home front door, garage door, or back door, Grade 3 certification confirms the lock has passed standardized durability and cycle testing appropriate for residential use. Always look for a stated ANSI grade on any lock you're considering — an unlisted grade means no independent verification.

Can I install a smart lock on any door?

No. Most residential smart locks — including all Veise models — are designed specifically for wood doors with a standard thickness between 1-3/8" and 2". They are not compatible with fiberglass, metal, storm, or sliding doors. Measure the edge of your door before purchasing, and confirm the material. If your door falls outside the standard range, contact the manufacturer before ordering.

Does a smart lock work if my Wi-Fi goes down?

Yes, with an important distinction. Keypad code, fingerprint (on equipped models), physical key, and key fob (where supported) all continue to work regardless of Wi-Fi status. For Smart Lock w/ Gateway 1/2 and Wi-Fi smart locks, even when Wi-Fi is down, app control continues to work locally as long as you're within short-range wireless distance of the lock. Only long-distance remote features — locking or unlocking from off-site, receiving alerts while away from home — require an active Internet connection.

What is the difference between a Smart Lock w/ Gateway and a Wi-Fi smart lock?

Both deliver full remote app control, but they achieve it differently. A Wi-Fi smart lock connects directly to your home router — no extra hardware required. A Smart Lock w/ Gateway 1/2 pairs with a small plug-in gateway device that handles the Internet connection on the lock's behalf, so the lock itself doesn't run a Wi-Fi radio. The right choice depends on whether you prefer a simpler one-device setup (Wi-Fi) or the gateway model with its added step of gateway placement.

Do all smart locks work with Alexa and Google Assistant?

No — voice assistant compatibility depends on the lock type. Veise Wi-Fi smart locks support Alexa and Google Assistant directly through their built-in Wi-Fi. Smart Locks w/ Gateway 1/2 also support voice commands, but only when the paired gateway is in place and connected. Keypad Deadbolt and Keypad Latch locks — with no Wi-Fi or gateway connectivity — do not support voice assistants. Always verify voice assistant support for the specific model and connectivity configuration, not just the brand category.

How fast is fingerprint recognition on a smart lock?

On Veise fingerprint-equipped models, the scan recognition speed is less than 0.3 seconds. Enrollment captures the finger eight times to build a reliable template across different angles and pressure levels. All fingerprint data is processed and stored locally on the lock itself — no cloud account, no Internet connection needed for biometric access, and no personal data leaving the device.

Is there a subscription fee for Veise smart locks?

No. Veise smart locks carry no subscription fee. Fingerprint data is stored locally on the device. Entry history, push notifications, and remote app control are all included without a monthly or annual charge. This is a meaningful long-term cost difference compared to brands that gate certain features behind a paid cloud plan.

How configurable is the auto lock feature?

Veise's auto lock interval is configurable between 10 and 99 seconds on Keypad Deadbolt and Keypad Latch locks, and between 10 and 180 seconds on connected models. You can set it short — 10 to 30 seconds — if you want the door to secure itself quickly after entry, or extend it (up to 99 seconds on the keypad-only lines, up to 180 on connected models) when you need more time getting through the door with groceries, kids, or guests. Auto lock is a standard feature across the entire Veise lineup, not limited to specific models.
