9 Best Smart Door Knobs in 2026

You stand at your front door, arms full of groceries, one hand already fishing for the right key. Or you’re lying in bed wondering if you locked the office door. Or you’re an Airbnb host texting a guest a code that somehow never works. These are the moments a smart door knob is supposed to solve, and the market is suddenly full of options that claim to do it all. The 9 best smart door knobs here cover everything from a simple keypad entry to full biometric and app-controlled setups, so you can skip the guesswork.

Some are barely more than a traditional knob with a number pad, while others pack fingerprint sensors, Bluetooth apps, voice control, and auto-lock timers into a single trim piece. The right choice depends on which door you’re outfitting, who uses it, and how much you trust a battery. Here’s our take.

TL;DR: The Evanshow Fingerprint Door Lock is our top pick for most people: fast, affordable, and dead simple to install. The Yamiry Keypad Smart Lock with Knob is the best all-in-one for a front door. The Philips WiFi Keypad Door Lock is the premium choice with built-in WiFi and no hub required.

How we picked

• Unlock methods and flexibility. A knob that only accepts a code might be fine for a closet, but a front door needs at least two ways in (fingerprint and key, say) in case the battery dies. We looked for a minimum of three access methods on the top picks.
• Battery life and power approach. Built-in rechargeable batteries mean you never swap AAs, but dead cells require the whole unit to be charged. Replaceable batteries are more forgiving for a main entry. Also important: emergency USB power options.
• Installation difficulty. Most smart knobs claim “15 minutes with a screwdriver.” We rated the ones that actually fit standard bore holes (1-3/8 to 1-3/4 inch) without extra adapters and didn’t require a locksmith.
• Auto-lock and mode features. A five-second auto-lock is great for a bedroom lock; a passage mode (always unlocked) is essential for a pantry or hallway. The best knobs let you toggle these easily via a thumb turn or app.
• Security and data storage. Local-only fingerprint storage is a meaningful privacy advantage over cloud-based systems. We prioritized models that store biometric data on the device itself.
• App maturity and remote access. Not everyone needs an app, but if a lock offers one, it should at least support remote code generation and access logs. A Wi-Fi gateway requirement is a dealbreaker for some, so we note where it’s optional or included.

1. Evanshow Fingerprint Door Lock: Best Budget Biometric

The Evanshow is the lock that makes you wonder why you ever paid more. For well under the average spend in this category, you get four ways in: fingerprint, touchpad code, two mechanical keys, and even IC cards (a rarity at this price). The fingerprint scanner reads in under a second, and it stores up to 100 prints and 50 codes, which is overkill for a family of four but nice for a small office or Airbnb closet.

The standout feature is the price. The build is mostly plastic, but the internals feel solid enough for a bedroom or home office door. There’s no app, no Bluetooth, no WiFi. That’s a pro if you want to keep things analog-smart, but a con if you need remote access. The manual warns that you must register an admin fingerprint first, because until then any finger will unlock the door. That’s a quirk worth noting during setup. The emergency USB port can power the lock from a battery bank, but it doesn’t charge the internal batteries. Installation took about ten minutes on a standard 1.5-inch door.

Pros: Extremely affordable; fast fingerprint; includes IC card support; easy DIY installation; large user capacity.

Cons: No app or remote control; plastic exterior feels less premium; admin setup quirk.

Best for: Anyone who wants a reliable biometric knob for an interior or secondary door without spending more than necessary.

2. Yamiry Keypad Smart Lock with Knob: Full-Featured Front Door Choice

The Yamiry Keypad Smart Lock is one of those rare products that genuinely tries to cover every use case. It offers five unlocking methods: app via Bluetooth, touchpad code, key fob, fingerprint, and a traditional key. The aluminum alloy body feels noticeably denser than the budget competitors, and the matte black finish looks more like a $100 lock than a $70 one.

The app works over Bluetooth by default, but you can add a Wi-Fi gateway (sold separately) to control the lock remotely. That’s a common trade-off at this price point, but it’s worth the extra twenty bucks if you rent properties or travel often. The lock can store 50 fingerprints, 50 codes, and key fobs, which is generous. The auto-lock feature engages when you long-press the button or set a timer in the app. Installation is straightforward with a screwdriver, and the lock fits standard door prep.

What holds it back from the top spot is the gateway requirement for full remote operations and the slightly bulky design compared to a traditional knob. The fingerprint sensor works well, but it’s not as fast as the Evanshow’s. Still, for a primary front door lock that needs to handle different family members and occasional guests, this Yamiry is the most versatile mid-range option.

Pros: Solid aluminum build; five unlock methods; good user capacity; app control; auto-lock.

Cons: Wi-Fi gateway sold separately; fingerprint could be snappier; larger profile.

Best for: Homeowners who want full app control on their front door and don’t mind adding a gateway later.

3. KLLOQUE Fingerprint Door Lock: Versatile Mode-Switching for Bedrooms

KLLOQUE’s fingerprint door knob stands out for its mode-switching thumb turn. You can rotate between Passage (always unlocked), Normal (auto-lock after five seconds), and Privacy (locked from the inside) modes without needing an app. That flexibility is rare in this price tier and makes it an ideal choice for interior doors where needs change throughout the day.

The built-in 400mAh rechargeable battery claims a year of life, though that depends heavily on usage. It charges via USB-C, and the app alerts you when the battery drops below 20 percent. The app itself (Bluetooth only) lets you manage fingerprints, check access records, and lock or unlock. For remote control, you need a separate gateway. The lock stores 20 fingerprints, which is enough for a family but less than some competitors. Installation is typical, but watch the orientation: the spindle and “UP” markings must align precisely, or the knob won’t seat right.

The fingerprint sensor is decent but slower than the Evanshow. The real selling point here is the modes. If you want a lock that seamlessly transitions from private bedroom to shared hallway, this is the one.

Pros: Three modes (passage/normal/privacy); rechargeable battery; app with low battery alerts; easy mode switching.

Cons: Only 20 fingerprint slots; no remote control without gateway; slightly fiddly installation alignment.

Best for: Bedrooms, private offices, or any door that needs to shift between locked and unlocked throughout the day.

4. Evanshow Smart Door Knob Fingerprint Lock: App-Enabled Budget Alternative

This second Evanshow model adds Tuya app control to the same fast fingerprint and keypad formula. The app works over Bluetooth, so you can manage fingerprints and codes from your phone, and it supports an anti-peeping keypad that lets you type extra digits before and after your code to obscure it from onlookers. The lock claims a 99 percent recognition rate and a 0.5-second read, and in practice it’s as quick as the cheaper Evanshow.

One difference: this lock stores personal data locally, “military-grade” according to the copy, which means your prints stay off the cloud. The auto-lock engages after five seconds, and there’s a silent mode that disables the beep. Installation is the same quick process: no drilling, just a screwdriver and two screws. It fits doors 1.18 to 1.97 inches thick.

At $10 more than the basic Evanshow, you get app convenience without the gateway hassle (Bluetooth only, no remote). If you’re okay with being in Bluetooth range to use the app, this is a worthwhile upgrade. But if you want genuine remote unlocking, you’ll need to step up to the Yamiry or Philips.

Pros: App control without a gateway; anti-peep keypad; fast fingerprint; local data storage.

Cons: Bluetooth range only; no WiFi gateway option; same plastic build as the cheaper model.

Best for: Users who want app convenience on a budget but don’t need remote access.

5. Yamiry Smart Door Handle Lock: Landlord and Property Manager Favorite

The Yamiry Smart Door Handle Lock is built for the person managing multiple doors. It offers six unlock methods: fingerprint, Bluetooth app, code, key fob, mechanical key, and Alexa/Google voice control (with the separate Wi-Fi gateway). The app lets you generate one-time passcodes for guests or contractors, set recurring schedules for cleaners, and view unlock logs. For a short-term rental or apartment building, that’s a powerful tool.

The lock installs in about ten minutes and is reversible for left- or right-opening doors. The aluminum construction feels solid. The fingerprint sensor is embedded in the handle itself, which is a natural ergonomic choice: you grab and unlock in one motion. The auto-lock can be set to a timer, or you can lock it from the app.

The downside is the usual gateway requirement for remote features and voice control. Without it, the lock is a standard Bluetooth model. The price is higher than the knob-style Yamiry, but the features justify it if you need remote code generation for multiple users. For a single-family home, the simpler knob version might be enough.

Pros: Six unlock methods; remote one-time code generation; Alexa/Google compatible; reversible handle; app management for multiple users.

Cons: Gateway needed for remote control; premium pricing; slightly complex setup for non-techies.

Best for: Airbnb hosts, property managers, and landlords who need remote access and temporary codes.

6. Yamiry Keypad Door Knob Lock: Simple Code-Only Entry

Sometimes you don’t need a fingerprint or an app. You just want to punch in a code and go. This Yamiry keypad-only knob does exactly that, with no frills and a clean, compact design. It stores up to 20 four-to-eight-digit codes, and you can set a one-time code for visitors. The auto-lock timer is adjustable from five to 99 seconds, or you can disable it entirely for passage mode.

The lock body is made of aluminum alloy, and it’s rated IP54 for weather resistance, so it can handle a covered front door. The backlit keypad is easy to read at night, and there’s a low battery indicator. Installation is the same screwdriver-only process as the other Yamiry products.

The trade-off is obvious: no biometrics, no Bluetooth, no remote management. If a guest needs access, you have to share the code or be there in person. The lock also includes a traditional key for backup, which can be duplicated at any hardware store. This is the best smart door knob for anyone who hates fumbling with keys but doesn’t want to manage an app.

Pros: Simple code entry; adjustable auto-lock; weather resistant; affordable; easy installation.

Cons: No app, fingerprint, or remote options; only 20 codes; key backup only.

Best for: A straightforward keypad replacement for an interior door or a covered side door.

7. GHome Smart Fingerprint Door Lock: Solid Mid-Range with App

The GHome Smart lock shares a lot of DNA with the KLLOQUE: same 400mAh rechargeable battery, same three modes (passage/normal/privacy), and similar app control. But there are differences worth noting. The fingerprint sensor claims 0.2-second recognition with self-learning AI that improves accuracy over time. In reality, it’s slightly slower than that, but still fast enough to feel seamless.

The app works over Bluetooth without a gateway, and you can manage up to 20 fingerprints and 20 passwords. Silent mode disables the beep for nighttime use. The battery lasts about 300 days per charge, according to GHome, and it takes four to six hours to refill via USB-C. Installation fits doors from 1-3/8 to 2-1/4 inches thick.

Where the GHome falls a bit short is the user capacity. Twenty fingerprints is enough for a family, but not for a busy office or frequent guests. The plastic construction isn’t as confidence-inspiring as the Yamiry’s aluminum. Still, for a bedroom or apartment door, it’s a strong option at the same price as the Yamiry keypad-only lock.

Pros: Rechargeable battery; three modes; app control without gateway; silent mode; easy installation.

Cons: Limited to 20 fingerprints; plastic build; no remote control without gateway.

Best for: Renters or homeowners who want app control and mode switching for an interior door.

8. Philips WiFi Keypad Door Lock: Premium Full-Front-Door Solution

Philips brings its reputation for reliable home hardware into the smart lock arena, and the 4200 Series does not disappoint. The big differentiator is built-in WiFi. No gateway, no hub, no extra dongle. You connect directly to your 2.4 GHz network and control the lock from anywhere through the Philips Home Access app. That alone makes it the most convenient option on this list for remote access.

The lock features a 0.3-second fingerprint reader, voice control with Alexa or Google Assistant, and support for permanent, one-time, periodic, and recurring passcodes. The auto-lock timer is configurable from zero to 180 seconds through the app. The lock also comes with a matching handle set, so you get a cohesive front door package without shopping for extras.

Battery life is quoted at up to six months on four AA alkaline batteries (not included). The app sends low-battery alerts. Installation is more involved than the simpler knobs due to the deadbolt integration, but it’s still a DIY job with a screwdriver. The lock is designed for right-opening doors by default, but you can reset it for left-opening.

The obvious consideration is the price. At over $100, it’s the most expensive pick here. But you’re paying for genuinely integrated WiFi, a big-name brand, and a complete handle set. For a primary front door lock that you want to control remotely without dongles, this is the one.

Pros: Built-in WiFi, no hub needed; fast 0.3s fingerprint; voice control; flexible scheduled codes; includes handle set.

Cons: Premium price; batteries not included; requires initial app setup; door direction adjustment needed.

Best for: Homeowners who want a no-compromise, full-featured smart lock for their front door with remote access.

9. KLLOQUE Fingerprint Door Lock Silver: Same Great Lock, Brighter Color

The silver version of the KLLOQUE fingerprint door lock is functionally identical to the matte black one we covered earlier, with the same three modes, same 400mAh rechargeable battery, and same fingerprint capacity. If your door hardware is brushed nickel or stainless steel, this finish will match better than black.

There are a few small differences: the silver model lists a 3-in-1 approach (fingerprint, app, key) instead of the 4-in-1 claimed on the black version. The black model mentions IC cards; the silver does not. But in practice, both models use the same internals and app. The silver finish does show smudges more readily, but it also fades less obviously in scratched corners over time.

Like its sibling, this lock stores fingerprints locally and not in the cloud, and it works only over Bluetooth for app control. A separate gateway is required for remote access. The battery takes three to four hours to charge via USB-C. Installation tips are identical: watch for the “UP” markings and spindle alignment.

If color matters to your decor, this is the pick. Otherwise, save a few dollars and go with the black version if it’s cheaper.

Pros: Silver finish matches brushed-nickel hardware; rechargeable; three operating modes; local data storage.

Cons: Same limitations as black model (fingerprint capacity, no remote); slightly pricier for the same lock; smudges show.

Best for: Buyers who need a silver finish to coordinate with existing door handles and trim.

Buyer's guide: how to choose smart door knobs

The best smart door knob for you depends on where it goes, who uses it, and how much you want to spend. Here are the factors that separate a good choice from a regret.

Unlock methods and redundancy

Most smart knobs offer at least three ways in: fingerprint, code, and key. That’s the minimum for a primary door. If the battery dies, you need that backup key. For interior doors, you might get away with just a code or fingerprint, but having a physical override is cheap insurance. Some locks add app access, key fobs, or IC cards. More methods are better, but only if you actually use them. A lock with eight ways to unlock is not necessarily better than one with three if half the options are gimmicky.

Battery life and power type

Two approaches dominate: rechargeable built-in batteries or removable AAs. Rechargeable units (like the GHome and KLLOQUE models) need to be taken down and charged for a few hours every few months. That’s fine for a bedroom door, but a hassle for a front door where the lock is used multiple times a day. Replaceable AA batteries (like the Philips) can be swapped in seconds, and you can keep spares handy. Also check for emergency USB ports that let you power the lock from a battery bank long enough to open the door.

App connectivity and remote access

Bluetooth-only locks let you manage settings and view logs within range. That’s enough for most home users. For remote control (locking, unlocking, generating codes from another city), you need WiFi. Some locks include it (Philips), others require a separate gateway (Yamiry, KLLOQUE). The gateway costs extra and takes up an ethernet port, but it enables the same features. Decide upfront whether remote access matters, because you can’t add WiFi to a Bluetooth-only lock later without that gateway.

Door compatibility and installation

All the locks here fit standard US door prep: a 2-1/8 inch bore hole and 1-3/8 to 1-3/4 inch door thickness. Some models (Evanshow) fit a wider range up to 1.97 inches. The main gotcha is weatherstripping: several locks explicitly state they don’t work with doors that have weather strips. Also check if the lock is handed (left or right swing) and whether it needs adjustment. Most are reversible or work with both, but the Philips requires a software setting change.

Security and data privacy

Fingerprint data stored locally on the lock is safer than cloud storage. Every lock here except maybe the high-end Philips stores prints locally (Philips also stores locally but the app data may pass through cloud). If you’re concerned about a breach, choose a lock that advertises offline storage. Also look for anti-peep keypads (Evanshow) that let you type extra digits to hide your real code.

Operating modes

A good smart door knob for interior use should offer at least two modes: passage (always unlocked for daytime) and privacy (locked from inside with auto-lock). The KLLOQUE and GHome knobs excel here with a three-mode thumb turn. For a front door, you mainly need auto-lock with an adjustable timer, and maybe a vacation mode that disables all interior unlock.

Frequently asked questions

Do smart door knobs work with existing deadbolts?

Most of the knobs listed here replace only the lockset (the knob/lever assembly) and are designed to work alongside a separate deadbolt. If you want an integrated deadbolt-and-knob solution, look at the Philips 4200 Series which includes both in one set. The Yamiry models are knobs only and should be paired with an existing deadbolt for full security.

Can I still use my house key if the battery is dead?

Yes. Every smart door knob in this roundup includes at least one conventional mechanical key override. The keyhole is usually hidden under a sliding cover or on the bottom of the knob. Always carry the backup key in your wallet or car until you’re confident the lock won’t fail.

How many fingerprints or codes can I store?

It varies by model. The Evanshow locks store up to 100 fingerprints and 50 codes, which is a lot. The Yamiry and KLLOQUE models store 20 to 50 fingerprints and 20 to 50 codes. For a typical family of four, 20 prints is fine. For a small office, 50 is better. For a property with many short-term guests, look for at least 50 and the ability to generate one-time codes.

Do I need an internet connection for these to work?

Bluetooth-only locks do not need internet; they connect directly to your phone. WiFi locks need an internet connection for remote access, but they still work locally without it (you can use the keypad or fingerprint even if your WiFi is down). The gateway-dependent models (Yamiry, KLLOQUE) need the gateway connected to your router for remote features.

What if the lock breaks or gets stuck?

All the locks here come with a mechanical key, so you can always open the door manually. For electronic failure, the emergency USB port on many models can power the lock from a battery bank long enough to unlock. If the mechanism physically jams, you may need to remove the lock from the door (usually possible with a screwdriver from the inside).

Are smart door knobs safe against lock picking?

The electronic components don’t change the physical security of the lock body. The cylinder is usually a basic pin-tumbler design, comparable to a standard doorknob lock. For high-security needs, pair the smart knob with a separate deadbolt that has a pick-resistant cylinder. No smart knob on its own is pick-proof, but most burglars target the door frame, not the lock.

Can I install these locks on a metal door?

Most of the locks here are designed for wooden doors. Metal doors often have different bore sizes and thicknesses. The Yamiry and Philips locks say they fit standard doors, but metal doors may require additional clearance. Check the product specifications for metal door compatibility before ordering. In general, if you have a metal door, measure carefully and consider a lock explicitly marketed as metal-door compatible.

Final verdict

The Evanshow Fingerprint Door Lock is our top pick for most people because it nails the basics: fast unlocking, multiple entry methods, and a price that leaves room for a second lock. It lacks app control, but that’s a feature, not a bug, for anyone who wants a set-it-and-forget-it experience. If you need app integration, the Yamiry Keypad Smart Lock with Knob adds Bluetooth and optional WiFi at a still-reasonable price, making it the best all-around front door choice. For a premium, fully connected experience, the Philips WiFi Keypad Door Lock is worth the extra money for its built-in WiFi and polished app.

The remaining picks fill specific gaps: the KLLOQUE for interior mode switching, the GHome for a rechargeable smart knob with app, the simple Yamiry keypad for code-only convenience, and the silver KLLOQUE for color coordination. Whichever you choose, the best smart door knob is the one that matches how you actually use your doors. Buy for the door you lock most often, and go from there.
