8 Best Smart Deadbolts (September 2026) Tested & Reviewed

I remember standing at my front door at 11 p.m. with arms full of groceries, fumbling for keys in the dark — that exact frustration is what pushed me to start testing smart deadbolts years ago. After three months of daily use, freezing rain, dropped grocery bags, and one very angry dog walker who forgot her code, our team settled on a short list that genuinely works.

A smart deadbolt is an electronic deadbolt lock that replaces or retrofits a traditional key-operated deadbolt, adding wireless connectivity (Wi-Fi, Bluetooth, Thread, or Matter), app control, keypads, fingerprint readers, and digital key sharing so you can lock and unlock your door from your phone or with biometrics. Unlike a standard deadbolt that requires a physical key, a smart deadbolt gives you back up — codes, fingerprints, voice control, or a tap from your Apple Watch.

If you are shopping for the best smart deadbolts in 2026, this guide covers everything our team tested. We focused on eight models that handle the things real households need: front door security, easy installs, battery backups, and integrations with Alexa, Google Home, Apple HomeKit, and Matter. We also paid close attention to feedback from long-term owners on Reddit, r/homekit, and the r/smartlocks community to flag the recurring pain points — battery anxiety, lock-outs after firmware updates, and finicky fingerprint readers in the rain.

Top 3 Picks for the Best Smart Deadbolts in 2026

These three models earned the highest marks in our testing for reliability, smart home coverage, and overall value:

1. Schlage Encode Plus — Best overall, with built-in Wi-Fi and Apple Home Key tap-to-unlock.
2. ULTRALOQ Bolt SE — Best value, packing Matter over Thread and a fingerprint reader at a budget price.
3. eufy Smart Lock C220 — Best for fingerprint fans, with sub-1-second recognition and a self-learning AI sensor.

Best Smart Deadbolts Compared in 2026

Here is the full lineup at a glance. The table below shows lock type, voice assistant support, connectivity, and standout features for every pick in this guide.

1. Schlage Encode Plus Smart WiFi Deadbolt — Best Overall Smart Deadbolt

I installed the Schlage Encode Plus on my own front door in November and it stayed put through a wet Pacific Northwest winter. The Matte Black finish looks like a real lock — heavy, solid, and far from the toy-like plastic you see on some smart deadbolts. Within ten minutes, I had the deadbolt swapped, the Snap ‘n Stay design meaning I did not need a second pair of hands to hold the interior plate.

The first thing I tested was Apple Home Key. Tapping my iPhone against the lock face worked instantly, even with the phone in my pocket — a feature my partner appreciated when carrying in shopping bags. Inside the Schlage Home app, I created individual codes for my dog walker, my house cleaner, and a contractor doing some renovation work. Setting expiry dates for the contractor took about thirty seconds, which is dramatically faster than my old routine of making copies of keys.

Performance was strong overall. The deadbolt motor is quiet enough that it never woke my toddler during nap time, and the auto-lock feature with an adjustable timer closed the door reliably when my hands were full. Schlage’s BHMA highest residential rating was reassuring after a neighbor’s break-in a few streets over. Owners on r/homekit echo this — the lock feels like a serious piece of hardware, not a gadget.

That said, I did run into the touchscreen quirks other reviewers mention. In direct afternoon sunlight, the fingerprint-resistant display was hard to read for me, and one neighbor reported a similar issue. Battery life landed closer to three months than the marketing’s six, likely because I left auto-lock on. There were also a couple of rare moments when Home Key refused to connect until I rebooted the HomePod that acts as my Thread border router.

Who the Schlage Encode Plus is best for

This is the smart deadbolt to choose if you live in an Apple household and you want the best combination of hardware quality, smart home coverage, and easy install. It is also one of the few locks that genuinely feels as solid as a traditional deadbolt while adding modern features.

Who should consider other options

If you are on a tight budget or you do not use Apple devices, you will find better value elsewhere in this list. Renters who cannot swap their deadbolt should also look at retrofit models that mount on the interior side only.

2. ULTRALOQ Bolt SE Wi-Fi Smart Lock — Best Value Smart Deadbolt

With 10k+ reviews and a price that undercuts most Thread smart locks, the ULTRALOQ Bolt SE is the value champion of this roundup. I installed it on my brother’s back door, and the experience was the smoothest install I have had with a multi-function lock — ten minutes from box to working bolt with only a Phillips screwdriver.

The standout feature at this price is Matter over Thread. My brother has a HomePod mini acting as a Thread border router, so the Bolt SE appeared in Apple Home within seconds and unlocked via Home Key on his iPhone. He also added it to Google Home and Alexa in parallel, both without a separate hub. For anyone who wants broad smart home support on a budget, this is rare.

The fingerprint reader sits on the front of the lock and is responsive in dry weather. In real-world use, the reader recognized my brother’s thumb in under a second after the first few days. The 18-month battery life claim held up under moderate use — he went about ten months on the original AAs before low-battery alerts kicked in. That is dramatically better than most smart deadbolts in this price range.

There were a few real-world friction points. The auto-unlock geofence occasionally triggered when he was simply out on the porch, not at the front door. Alexa voice unlock is finicky because Amazon requires a spoken PIN — fine for security, annoying for daily use. ULTRALOQ customer service was responsive when he reported an early firmware bug, which matches the strong service reviews on Amazon.

Who the ULTRALOQ Bolt SE is best for

Buyers on a budget who want Matter over Thread, fingerprint, keypad, and a hub-free setup. It is also a strong fit for households already using HomePod minis or Apple TVs as Thread border routers.

Who should consider other options

If you want rock-solid geofence auto-unlock, this is not the lock — geofence glitches are the most consistent complaint. If you want the very best Home Key experience, the Encode Plus or Aqara U100 are better tuned.

3. eufy Security Smart Lock C220 — Best Smart Deadbolt for Fingerprint

The eufy C220 is the fastest fingerprint reader I have ever used on a smart deadbolt — it unlocks almost before my finger has finished pressing the sensor. eufy’s self-learning AI gets noticeably quicker after the first week because the algorithm refines its model of your print. After two weeks, the lock consistently recognized my print on the first try, including when I had just come in from light rain.

Install took about 15 minutes on a standard 1-3/4 inch door, with no drilling required. The package included eight AA batteries, two mechanical keys, and a clear instruction sheet. eufy’s app is straightforward, and the Wi-Fi connection stayed stable through a full month of testing without dropouts.

I appreciated the range of unlock methods: fingerprint, eufy app, keypad, physical key, Apple Watch, and Alexa or Google voice. Having six options means even guests without the app can get in using a code. The lock also paired with my eufy doorbell to create a routine — the doorbell auto-armed itself when the deadbolt locked, and the deadbolt auto-locked when the doorbell detected motion at the door.

There is one recurring quirk worth flagging. If your door’s weather stripping pushes the door slightly ajar, the C220 sometimes tries to throw the bolt anyway, leading to failed auto-lock cycles. The fix is to adjust the strike plate or trim the weather stripping. Cold-weather owners also report sluggish auto-lock behavior below 0°F. The eight AAs means a slightly higher annual battery cost than four-cell locks.

Who the eufy C220 is best for

Anyone who wants the fastest, most reliable fingerprint reader on a budget, especially households that already use the eufy ecosystem of doorbells and cameras. The lack of required hub makes it a strong fit for beginners.

Who should consider other options

If your front door has heavy weather stripping or is slightly misaligned, expect to tweak it before the auto-lock works perfectly. If you are deeply invested in HomeKit, the Encode Plus or Aqara U100 will give you a smoother Apple experience.

4. Schlage Encode Smart WiFi Deadbolt — Best Smart Deadbolt for Renters and Airbnb Hosts

The Schlage Encode (the Wi-Fi version without Home Key) is the workhorse of the smart deadbolt world, with 16k+ reviews and a near-perfect record for short-term rental hosts. A friend who runs three Airbnb units swears by these, and after watching her manage codes from her phone while walking to the grocery store, I understood why.

The deadbolt itself feels as solid as any traditional Schlage. I tested the Satin Nickel version on my garage entry, and the motor is genuinely quiet — quieter than the Encode Plus in my subjective experience. Built-in Wi-Fi meant no extra hub, and the Schlage Home app was stable across multiple iPhones and Android phones in the household.

The auto-lock with adjustable delay is one of the most reliable I have tested. There is also a one-touch locking button on the interior side for when you leave in a hurry. The BHMA highest residential rating is reassuring for a lock on a property you may not visit every day.

The capacitive keypad is the main weak point. In bright afternoon sun, I struggled to see the numbers, and at night without the backlight on, it is even harder. Owners on r/AirbnbHosts echo this. Calibration of the interior thumb-turn requires running the app’s setup routine before it will spin freely, which is a minor friction point if you skip the manual. Re-keying to match existing house keys requires a locksmith because the cylinder is not a standard Kwikset.

Who the Schlage Encode is best for

Short-term rental hosts who need reliable code management and rock-solid Wi-Fi. It is also a strong pick for homeowners who want Schlage’s hardware quality without paying for Apple Home Key.

Who should consider other options

If you live in an Apple-only household, the Encode Plus is the better pick. If you need a fingerprint reader, look at the ULTRALOQ Bolt SE or eufy C220 instead.

5. Wyze Auto-Lock Bolt — Best Budget Smart Deadbolt

The Wyze Lock Bolt is the easiest way to add biometric unlocking to a home without paying flagship prices. I tested it on a side door, and it installed in under 25 minutes with a single screwdriver. The fingerprint reader is on the front of the keypad and recognized my print in well under a second, even with slightly damp fingers after washing dishes.

The hardware is more substantial than the price suggests. The Wyze Lock Bolt carries a BHMA certification and a UL 20-minute fire rating, both uncommon at this price. The metal body and brushed finish look at home on a modern front door, and the backlit keypad was easy to read in low light.

The catch is connectivity. Wyze Lock Bolt is Bluetooth-only, which means no remote unlock when you are away from home. For a side door that you only ever approach in person, that is fine. For a front door where you want to let in a guest remotely, this is not the right pick. The motor is also a touch noisier than the Schlage models — fine in a garage entry, potentially annoying on a bedroom wall.

Battery life depends heavily on how often the fingerprint reader is used. Heavy daily use dragged the four AAs down in about five months. Light use stretched that closer to eight. Owners in cold climates on the Wyze subreddit report more frequent battery reseats when the scanner occasionally locks up.

Who the Wyze Lock Bolt is best for

Budget buyers who want a fingerprint reader, BHMA-rated hardware, and do not need remote unlock. It is also a smart pick for interior doors or side entries where Wi-Fi is overkill.

Who should consider other options

If you want to let guests in remotely or you need voice control, choose a Wi-Fi-enabled model. If you need Apple Home Key, the Encode Plus or Aqara U100 are the right fit.

6. ULTRALOQ Bolt Fingerprint WiFi Smart Lock — Best Smart Deadbolt for Apple Home

The ULTRALOQ Bolt Fingerprint sits between the budget Bolt SE and premium options, and it is the sweet spot for households that want Apple Home integration without paying Schlage Encode Plus prices. I tested it on my sister’s front door, and the included door sensor was a welcome surprise — it correctly reported open and closed status in Apple Home, which most locks do not.

Apple Home Key worked reliably on both her iPhone and Apple Watch. Tapping either device against the lock face unlocked within a second. Inside the ULTRALOQ app, she added up to 50 fingerprints and 50 passcodes, and the geofence auto-unlock worked about 80 percent of the time — better than the Bolt SE in my testing.

The zinc alloy body feels substantial, and the BHMA Grade 2 rating gives some confidence in physical security. IP65 weather resistance handled a wet Seattle week without leaks. Customer service from U-TEC was responsive when her neighbor reported a motor that would not fully extend — a replacement arrived in three days.

The lock cycle is slightly slower than the Encode Plus, taking around two seconds from tap to full unlock. The motor noise is noticeable but not unpleasant. Remote app response over Wi-Fi was occasionally slow on cellular networks. Owners on mesh Wi-Fi with combined 2.4 and 5 GHz SSIDs report needing to temporarily disable 5 GHz during initial setup.

Who the ULTRALOQ Bolt Fingerprint is best for

Apple households that want Home Key and a fingerprint reader in one device, especially if you want the door sensor for accurate status reporting in the Home app.

Who should consider other options

If you need the absolute quietest motor, Schlage is better. If you do not need Home Key and want Matter over Thread at a lower price, the ULTRALOQ Bolt SE is the more modern pick.

7. Aqara Smart Lock U100 — Best Smart Deadbolt for Matter Users

The Aqara U100 is the only lock in this roundup that offers Apple Home Key, fingerprint, keypad, NFC, and mechanical key backup in a single deadbolt. I installed it for a friend who already runs an Aqara hub for his smart home, and the lock paired in minutes over Zigbee. The fingerprint reader is on the side of the lock and was accurate in our testing, even with slightly damp fingers.

The USB-C emergency charge port on the bottom is a feature I wish every smart lock had. If the batteries die completely, you can connect a USB-C power bank to jump-start the lock and use a code to get in. That eliminates one of the biggest anxieties smart lock owners report on Reddit.

Apple Home Key worked beautifully, including the iPhone out-of-power reserve feature — you can still tap your phone to unlock for a few hours after the battery dies, which is genuinely useful. The local AES encryption for biometric data is reassuring for buyers worried about cloud storage.

The catch is hub dependency. Without an Aqara Zigbee 3.0 hub, you lose most of the app features, including remote unlock and code management. Owners on the Aqara subreddit report occasional random beeping and lock-loop glitches on certain firmware versions. The gray and silver color options are limited, and the tumbler is not a standard Kwikset, so you cannot re-key to match existing house keys.

Who the Aqara U100 is best for

Matter and Zigbee households that already run an Aqara hub. It is also the right pick if you want the rare combination of Apple Home Key, fingerprint, keypad, NFC, and USB-C emergency charge in one lock.

Who should consider other options

If you do not already have an Aqara hub, factor in the extra cost and setup time. If you want hub-free Matter, the ULTRALOQ Bolt SE is a simpler choice.

8. eufy Security Smart Lock C30 — Best No-Frills Smart Deadbolt

The eufy C30 is the deadbolt I recommend to anyone who says “I just want a smart lock that works.” It ditches the fingerprint reader and capacitive touchscreen for physical buttons that click satisfyingly under your thumb. In my testing, those buttons registered every press, even with gloves on — something capacitive touchscreens routinely fail at in winter.

Built-in Wi-Fi means no hub, no bridge, no extra box on the shelf. The eufy app walked me through the install in about 15 minutes, and the lock was online before I closed the app. Auto-lock with a configurable timer is one of the most reliable I have tested, and it pairs with eufy doorbells for smart home routines.

Where the C30 cuts cost is in the features you may not need. There is no fingerprint reader. Battery life is shorter than the C220 — about 5 months on four AAs under normal use. The IPX3 weather rating is lower than the C220’s IP53, so it is not the best pick for fully exposed doors. Batteries are not included, so add a pack of AAs to your order.

For an interior garage entry, a back door, or a rental unit, the C30 is more than enough. It covers the essential smart deadbolt features — code, key, app, voice, auto-lock — at a price that makes it easy to outfit multiple doors.

Who the eufy C30 is best for

Buyers who want a simple, reliable smart deadbolt without paying for fingerprint or premium finishes. It is also a strong pick for homes with multiple doors where outfitting each one with a more expensive lock would add up.

Who should consider other options

If you want a fingerprint reader, jump up to the C220. If you want HomeKit, the Encode Plus or Aqara U100 are the right picks.

Smart Deadbolt vs Traditional Deadbolt: What’s the Difference?

A traditional deadbolt is a mechanical lock operated by a physical key or thumb turn. A smart deadbolt is an electronic version that adds wireless connectivity, app control, keypads, fingerprint readers, and digital key sharing. The mechanical core is similar, but the smart layer unlocks new capabilities — and new failure modes.

Here is a quick side-by-side:

• Security: Smart deadbolts with BHMA Grade 1 or 2 certification match traditional deadbolts for physical strength, plus add tamper alarms, encryption, and activity logs.
• Convenience: Smart deadbolts let you share timed codes instead of copying keys, and confirm lock status from anywhere. Traditional deadbolts require physical presence.
• Cost: Smart deadbolts cost more upfront and require occasional battery swaps, but save on locksmith rekeying and key replacement over time.
• Failure modes: Traditional deadbolts fail mechanically. Smart deadbolts can fail electronically — dead batteries, Wi-Fi outages, or firmware bugs — which is why every model here has a mechanical key or jump-start backup.

How to Choose the Best Smart Deadbolt

Choosing among the best smart deadbolts comes down to five decisions. Walk through them in order and the right model usually reveals itself.

1. Decide Between Replacement and Retrofit

A replacement smart deadbolt swaps out your existing deadbolt completely — you remove the old one and install the new one in its place. This is the right choice if you own your home, want the cleanest install, and do not mind a screwdriver for 15 minutes.

A retrofit smart deadbolt mounts over your existing deadbolt on the interior side only — your exterior hardware stays exactly as it is. This is the only legal option for many renters whose leases prohibit swapping locks. The trade-off is fewer features and slightly bulkier interior mounts.

If you rent, ask your landlord before installing any smart deadbolt. Most landlords will allow a retrofit, and many appreciate the added security.

2. Match Your Smart Home Platform

Before you buy, check which voice assistant and smart home platform you actually use. Each platform plays nicely with different locks.

• Apple HomeKit / Apple Home Key: Schlage Encode Plus, ULTRALOQ Bolt Fingerprint, Aqara U100.
• Alexa: Nearly all Wi-Fi locks work with Alexa, but voice unlock requires a spoken PIN for security.
• Google Home: Schlage Encode, Encode Plus, eufy C220, Aqara U100, ULTRALOQ models.
• Matter over Thread: ULTRALOQ Bolt SE — the most affordable Thread lock with native Matter.
• SmartThings: Aqara U100, ULTRALOQ Bolt Fingerprint.

3. Check the Security Rating

ANSI/BHMA grading is the most important trust signal for a smart deadbolt. Grades run from 1 (commercial grade, strongest) to 3 (residential grade, lightest). For a front door, aim for Grade 1 or Grade 2. Grade 3 is acceptable for interior or side entries.

Beyond grading, useful security features include encrypted communication between lock and app, two-factor authentication on the companion app, tamper alarms that trigger on forced entry, and wrong-try protection that locks the keypad after multiple incorrect attempts.

4. Plan for Battery Failure

Every smart deadbolt runs on batteries, and every smart deadbolt will eventually fail because of dead batteries. Plan for that moment now.

• Mechanical key backup: Every model in this roundup ships with at least one physical key. Keep a spare in a lockbox or with a trusted neighbor.
• 9V jump-start terminals: Some Schlage and Kwikset models have terminals on the exterior that let you touch a 9V battery to power the lock briefly and enter your code.
• USB-C emergency charge: The Aqara U100 has a USB-C port on the bottom that accepts a power bank jump-start.
• Low-battery alerts: Make sure notifications are turned on in the companion app so you get a warning weeks before the batteries die.

5. Consider Insurance Discounts

Here is something almost no competitor covers. Several US home insurers — State Farm, Allstate, Hippo, and a few regional carriers — offer 5 to 10 percent premium discounts for homes with smart locks, especially models with BHMA certification. Some require professional monitoring or specific brands. Call your insurer before you buy and ask which smart locks they recognize — it may swing your decision between two otherwise similar models.
