Front-door security today is less about the key in your pocket and more about how many ways you can get in — and who you can keep out. The best modern deadbolts read your fingerprint in under a second, lock themselves behind you, and send a notification to your phone the moment someone opens the door. This guide breaks down nine of the most capable smart deadbolts on the market, sorted by what they actually do well in daily use.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
A smart deadbolt’s core job is to keep unauthorized entry out while letting you in without fumbling for keys. These door locks for security pair smart features like fingerprint sensors (which open up in under a second) with battery life that lasts months, so you get both convenience and protection without constant recharging.
Our Picks at a Glance
How To Choose The Best Door Locks for Security
Buying a smart lock means weighing convenience against real-world reliability. Your ideal deadbolt balances open up methods, battery life, and installation fit against your household’s daily routine.
Match the Lock to Your Door’s Hardware
Most modern deadbolts fit standard doors, but not all. Check your door’s thickness — the Tapo DL100 and DL110 fit the standard 2-1/8″ (54mm) and 1-1/2″ (38mm) bore holes without drilling. The TEEHO TE012W goes further, fitting doors 1-3/8″ to 2″ thick, which covers nearly every residential door in the US. Measure your backset (the distance from the door edge to the hole center) before ordering.
Weigh open up Methods Against Your Household
Fingerprint sensors are the fastest way in, but they fail on wet or dirty hands. A good lock gives you a fallback — a keypad code, a physical key, or an app. The Wyze Auto-Lock Bolt v2 offers fingerprint, app, code, and key, so you always have a way in. If you host guests or have a cleaning service, look for temporary codes you can expire remotely.

In‑Depth Reviews
1. Wyze Auto-Lock Bolt v2
Our pick — over 4.5★ from 500+ verified ratings; the strongest balance of quality and price.
The deadbolt that opens in half a second and learns your fingerprint better with every touch.
Speed is the headline here. The Wyze Bolt v2 open up in 0.5 seconds with its fingerprint scanner, and its glass face resists smudges so reads stay clean. Owners are most vocal about reliability and how easy it is to install — the full setup takes under 10 minutes with a Phillips screwdriver, and all parts plus batteries come in the box.
Smart features go beyond the basics. The Wyze app handles remote lock and open up, notifications, temporary codes, and schedule-based access. If the batteries die, a USB-C port lets you power the lock with any common power bank. It claims 8 months of battery life from its 8 AA batteries, which is strong for a Wi-Fi-connected deadbolt.
Compared to the TEEHO TE012W, the Bolt v2 is heavier at 1.47 kg versus 0.92 kg, which gives it a more substantial feel. It also measures larger at 7.09 x 2.93 x 1.41 inches, so confirm your door has clearance. Its 0.5-second fingerprint read, sturdy build, and reliable Wyze app control make it the top pick for most homes.
What wins people over
- 0.5-second fingerprint open up with AI learning
- USB-C emergency power backup
- Auto-lock and remote control via Wyze app
- Simple 10-minute installation
What to watch
- Larger than a standard deadbolt — check clearance
- Fingerprint performance gets mixed feedback in some reviews
Reach for this if: you want the best all-around smart deadbolt with a fast fingerprint reader and reliable app control.
Look elsewhere if: your door has tight clearances and won’t fit a larger-than-standard deadbolt body.
2. TEEHO TE012W
A budget-friendly deadbolt that brings solid Wi-Fi, a fingerprint reader, and five ways to open up.
The TEEHO TE012W proves you don’t need to spend premium money for a dependable smart lock. It connects directly to 2.4GHz Wi-Fi with no hub required, works with Alexa and Google Assistant, and gives you five open up methods: app, fingerprint, passcode, key, or voice control. It supports up to 20 fingerprints and 100 codes, which covers a large household or small office.
Battery life is a standout. Buyers report their batteries lasted 36+ weeks in cold, high-traffic use — well beyond what most Wi-Fi locks deliver. The lock uses 8 AA batteries; standard designs often use 4. The KK Home app sends low-battery alerts before you’re caught out.
Security features punch above the price. It’s BHMA Grade 3 certified and rated IP55 for outdoor weather resistance, handles rain and snow, and includes break-in detection — after 10 consecutive wrong PIN attempts, the lock disables for 3 minutes and sends an alert. The anti-peep password lets you add random digits before or after your real code. At just 0.92 kg, it’s noticeably lighter than the Wyze Bolt v2’s 1.47 kg, and it’s more compact at 5.12 x 2.95 x 1.3 inches.
The strong points
- 36+ weeks battery life reported in real use
- Five open up methods including voice control
- BHMA Grade 3 + IP55 weather resistance
- Anti-peep password and break-in lockout
The trade-offs
- Requires 8 AA batteries upfront
- Occasional brief “abnormal state” alerts reported
Best if: you want proven Wi-Fi performance and serious battery life without the premium price tag.
Think twice if: you’re bothered by the occasional app alert for a non-issue.
3. Tapo Smart Wi-Fi Deadbolt DL100
The tactile-button deadbolt that handles 200 custom codes and knows exactly who came and went.
Installation is where this Tapo lock shines — it’s the most-praised aspect of the DL100, and buyers mention the clear instructions and simple setup. The lock fits standard 2-1/8″ (54mm) and 1-1/2″ (38mm) bore holes with no drilling required. Its metal exterior feels durable, even though the interior is plastic.
Access management is genuinely flexible. The Tapo app lets you create groups for family, guests, or visitors, with up to 200 customizable codes. You can set custom profiles and track every entry with timestamps — perfect for knowing when the kids got home or when the dog walker let themselves in.
Battery life is a strong selling point: up to 200 days in Wi-Fi mode or 300 days in Bluetooth mode, powered by 4 included AA batteries. A USB-C port provides emergency power. It carries BHMA Grade 3 certification and an IP54 weatherproof rating, so rain and dust won’t slow it down. Unlike the fingerprint-first competition, this lock uses tactile buttons and Bluetooth for nearby access, which some users prefer for reliability.
Why it stands out: The 5/10/15-minute auto-lock timer is a favorite among forgetful households — the door secures itself on schedule.
The honest note: A few owners mention notifications drop periodically, usually fixed by a quick battery reset.
Grab this when: you manage multiple people and need groups, timestamps, and up to 200 codes.
Consider another if: you specifically want fingerprint entry — this lock skips biometrics for tactile buttons.
4. Veise VE027
A deadbolt that pairs 0.2-second fingerprint reads with a surprising trick — it rekeys to your Schlage key.
The Veise VE027 is a feature monster. It offers 7 ways to open up: remote app, fingerprint, PIN codes, voice, authorized admin, IC cards, and physical keys. The fingerprint sensor uses AI self-learning with a claimed 99.8% accuracy, and customers note it works well for family members, though kids may need to use their thumbs.
What sets this lock apart is rekeyability. One owner successfully rekeyed it to their Schlage key by swapping pins, turning a smart lock into a natural extension of their existing key system. That’s a level of integration most locks in this price range simply don’t offer.
Battery life is rated at 8 months from 8 AA batteries. The IP65 weatherproof rating is the highest in this lineup, and it ships with a 2-year total warranty when you register. One honest caveat from reviews: battery life reports vary — some owners see 3 months in heavy use, so keep the low-battery alerts on. At 8.17 x 6.3 x 7.91 inches, it’s a substantial unit, so measure before you buy.
Loaded with features
- 0.2-second fingerprint open up with AI learning
- Rekeyable to Schlage keys
- IP65 weatherproof — highest rating here
- 7 open up methods including IC cards
Keep in mind
- Battery life varies — some report 3 months
- Larger physical footprint
Choose this if: you want the most open up options and the ability to match your existing Schlage key.
skip it if: you need consistent 8-month battery life and prefer a slimmer profile.
5. Veise VE027-K
A complete deadbolt-plus-two-knobs set that gives every family member their favorite way in.
The VE027-K takes the strong fingerprint tech of the VE027 and bundles it with two matching knobs, making it a full door hardware upgrade. The 0.2-second fingerprint open up runs on a 608DPI sensor with a claimed 99.99% accuracy, and owners say it works flawlessly for family members. It stores up to 20 fingerprints — plenty for a busy home.
You get eight ways to enter: remote app, fingerprint, IC card, PIN, key, voice with Alexa or Google, user authorization, and code sharing. The 8 AA batteries deliver up to 240 days of use, and the backlit touchscreen keypad makes nighttime entry painless. Auto-lock timers range from 10 to 180 seconds, so the door secures itself behind you.
This set shines as a functional upgrade. A wellness center owner bought it specifically to stop changing locks every time an employee left — codes can be revoked instantly from the app. You can revoke or grant access instantly from the app, eliminating the need to rekey locks between tenants or employees. It’s also an easy DIY install, taking 10-15 minutes with just a screwdriver for standard US doors (1-3/8″ to 2″ thick).
The defining strength: Eight entry methods plus remote management make this ideal for offices or families where different people need different access.
The thing to know: Travel mode is a nice extra — it blocks all entry except the physical key when you’re away.
Reach for this if: you’re outfitting a whole door with matching hardware and want eight ways to get in.
Pick something else if: you don’t need the extra knobs and just want a single smart deadbolt.
6. Sifely Model O
A landlord-friendly deadbolt in bright brass that stores over 100 fingerprints and revokes access instantly.
The Sifely Model O targets a specific buyer: the short-term rental host or landlord who manages many guests. Installation is its biggest praise — owners call it easy and quick, with no drilling needed. It fits standard single and multi-family homes, apartments, and rentals, supporting both left and right doors.
Access management is built around flexibility. It stores up to 100+ fingerprints and 100+ codes, and the free app lets you share eKeys, check logs, and set schedules. The one caveat: remote access requires the Sifely Gateway, which is sold separately. If you want to change codes from your phone while traveling, you’ll need that extra piece of hardware.
open up methods include fingerprint, keypad, fob, app, and physical key. The fingerprint reader gets mixed feedback — some owners say it’s fast and accurate, while others note it can be sensitive to placement and works best with completely clean, dry hands. Auto-lock is available, plus privacy and passage modes. It’s a solid, affordable choice for landlords who want to stop rekeying locks between tenants. At 6.3 x 2.6 x 1.9 inches, it fits most standard door prep.
Why landlords like it
- 100+ fingerprints and 100+ codes
- Easy DIY installation, no drilling
- Privacy and passage modes for flexible access
- Multiple open up options
The catch
- Remote app control needs a separate gateway
- Fingerprint reader needs exact placement and clean hands
Best for: rental hosts and landlords who need to revoke and grant access without changing locks.
Not ideal if: you want out-of-the-box remote control without buying an extra gateway.
7. eufy Security Smart Lock C33
A keypad-plus-handle combo that works as a lever lock, so you may not even need a separate deadbolt.
The eufy C33 combines the deadbolt and handle into one unit, which changes how you think about the door. It’s a lever-style smart lock with a fingerprint reader built into the grip — you open up and open in one motion. Reviewers point out a fast fingerprint reader and an easy 15-minute install with no drilling. It works on left- and right-hand doors, making it ideal for side doors, offices, or garages.
Battery life comes from 8 AA batteries, and owners have a clear recommendation: replace the stock batteries with Energizer Ultimate Lithium or quality rechargeables, as the included ones run down quicker. Auto-lock is available, and scheduling lets you set the door to lock itself at night and open up in the morning — a feature owners specifically praise for forgetful households.
A key consideration: this lock ships with an 18-month coverage and 24/7 customer service, which is solid for the category. It weighs 1.9 kg and measures 8.66 x 7.1 x 3.15 inches, so it’s a substantial unit. The eufy app gives you codes, fingerprints, and open up notifications all in one place. Some owners note the beefy deadlatch may need the deadbolt position swapped for proper clearance, so check your door’s configuration.
The real advantage: One-handed entry — fingerprint on the grip and the door opens, no separate deadbolt turn needed.
What to plan for: Swap in quality batteries from day one for the best longevity.
Choose this if: you want a combined handle-and-lock solution for a side or office door.
Consider the traditional route if: you prefer keeping your existing handle and just swapping the deadbolt.
8. Tapo Smart Wi-Fi Deadbolt DL110
The deadbolt with a rechargeable battery that lasts a full year and open up in 0.42 seconds.
Battery anxiety ends here. The Tapo DL110 uses a removable, rechargeable battery pack that delivers a full year of continuous operation — shoppers say the battery still reads 100% after months of daily use. No more buying AA batteries every few months. The fingerprint sensor open up in just 0.42 seconds and can store up to 100 fingerprints.
Build quality and reliability are the two most-praised aspects of this lock. It’s BHMA Grade 2 certified, which is a step above the Grade 3 rating most smart locks carry. Owners who switched from other premium brands, including Nest x Yale, call this a clear upgrade — easier installation, better fingerprint recognition, and that rechargeable battery that eliminates the every-6-weeks battery change ritual.
You get six ways to access: fingerprint, keypad codes, Wi-Fi app control, Bluetooth, smart home assistant, and two backup keys. Resident profiles let you set permanent codes, while guests get one-time or scheduled codes you control from the Tapo app. At 2.09 kg it’s the heaviest lock here, a sign of the solid construction. The one integration note: native Home Assistant support is limited, so smart-home tinkerers may need a bridge.
The premium upsides
- 1-year rechargeable battery — no AA swaps
- 0.42-second fingerprint open up
- BHMA Grade 2, above most competitors
- Up to 100 stored fingerprints
Considerations
- Heaviest option at 2.09 kg
- Limited native smart-home integration for some hubs
Pick this if: you’re tired of changing batteries and want the most durable, reliable smart deadbolt.
Go elsewhere if: your smart home runs on Home Assistant and you want native integration without a bridge.
9. eufy Security Smart Lock C220
A self-learning fingerprint deadbolt built for the eufy ecosystem, open up in under 1.5 seconds.
The eufy C220 slots into the wider eufy Security system. If you already have a eufy doorbell, you can add this lock to your routines and control them together in the eufy Security app. For eufy owners, that integration is the headline feature — open up from the doorbell feed or check lock status alongside your cameras.
The self-learning AI fingerprint recognition gets more precise with every touch, open up in under 1.5 seconds. Owners praise how well it works for families, with one buyer managing multiple units for short-term rentals and tracking exactly who locks and open up each door. The 8 AA batteries deliver around 8 months of use, with real-world reports landing even higher — one owner’s batteries lasted 11+ months.
Six ways to open up: fingerprint, the eufy Security app, keypad, physical key, Apple Watch, or voice control with Alexa and Google Assistant. It carries an IP53 rating and operates from -22°F to 158°F, so extreme temperatures won’t stop it. Built-in Wi-Fi means no extra bridge for remote control. The recurring note in reviews is the fingerprint reader — it works reliably for most, but a few family members find it inconsistent and fall back to the PIN pad.
The special advantage: Deep eufy ecosystem integration — lock and open up alongside your doorbell and cameras in one app.
The balance: Fingerprint recognition is great for most users but may need the keypad as a fallback for others.
Best if: you’re already in the eufy ecosystem and want your lock to work with your doorbell.
Think twice if: you want an IP65 weather rating — this lock offers IP53 protection instead.
Understanding the Specs
Fingerprint Speed and Accuracy
Fingerprint open up times range from 0.2 seconds (Veise VE027) to 1.5 seconds (eufy C220). Faster feels snappier, but accuracy matters more. The Wyze Bolt v2 uses AI learning to improve recognition with every touch. The Tapo DL110 stores up to 100 fingerprints and open up in 0.42 seconds. If your hands are often wet or dirty, a fingerprint sensor may struggle — keep a keypad code as backup.
Battery Life and Power Backup
Battery ratings vary widely: the Tapo DL110’s rechargeable pack lasts a full year, while the Wyze Bolt v2 and Veise locks claim 8 months from 8 AA batteries. Real-world results depend on Wi-Fi usage — heavy remote access drains faster. Look for USB-C emergency ports (Wyze Bolt v2, Tapo DL100) so a dead battery never locks you out.
