10 Best Amazon Prime Big Deal Days Smart Lock Deals (October 2026 Sale)

If you want one smart lock to watch during Amazon’s October sale, the Schlage Encode WiFi is the pick most people should look at first. It carries WiFi inside the deadbolt, so there is no hub to buy or bridge to configure, and it has been collecting owner feedback for years at a scale none of the other locks here can match.

Two other names matter for this sale. The ULTRALOQ Bolt SE is the value pick, with fingerprint entry, Matter over Thread and a battery figure that stretches a year and a half. The Sifely Smart Lock S is the one to watch if you hand out temporary PINs to guests, cleaners or dog walkers. Prime Big Deal Days runs October 6-7, 2026, and most offers on these locks sit behind a Prime membership.

Our Top 3 Picks for Best Amazon Prime Big Deal Days Smart Lock Deals

These three cover most households. One is the safe long-term buy, one is the spec-heavy value option, and one is built around temporary access codes.

Best Amazon Prime Big Deal Days Smart Lock Deals Compared

Every lock below does the same core job, so the useful comparison is what each one asks you to give up. Four fields decide it most often: who the lock suits, how many ways you can get in, what radio hardware is built in, and how long the batteries last.

How We Chose

We compared the specs that actually decide a smart lock purchase: how many ways the door opens, what radio hardware sits inside the housing instead of in a hub, battery life, the security certification, door thickness fit and installation time. We also weighed owner reviews and ratings on Amazon, since a lock is a long-term install and first impressions matter more here than a spec sheet. Data was checked in (October 2026).

1. Schlage Encode WiFi: Best for Remote Access on a Main Door

The Schlage Encode WiFi leads this list because it does the unglamorous things properly. WiFi is in the deadbolt, not in a separate bridge, and the whole install is two screws and a screwdriver with no wiring and no electrician.

Owners treat it as a long-term install. At more than 13,000 reviews, it has one of the longest feedback records of any smart lock on Amazon, and the recurring positives are the physical backup key, the auto-lock timer and the range of trim finishes.

For a household that wants remote access without buying extra hardware, the code capacity is the quiet strength. Up to 100 access codes means a code per family member, per sitter, per contractor, and you can pull up lock history from anywhere.

There is a built-in alarm that fires on door movement and forced entry attempts, and the touchscreen is fingerprint-resistant. The connection is encrypted, and the lock carries the highest residential BHMA security, durability and finish rating.

Compared with the ULTRALOQ Bolt SE, the Encode trades fingerprint reading for a cleaner, more established app and a much longer track record. If you want a finger reader or Matter, the Bolt SE is the better fit. If you want one lock that quietly works for a decade, this is it.

Owners are most divided on the touchscreen, which some find less precise than physical buttons in the rain. That same complaint is why the Schlage Arrive WiFi gets the nod for pure keypad feel. Battery life is listed at up to six months from four AA cells, with a low-battery indicator on the lock itself and in the app, plus one physical backup key.

2. ULTRALOQ Bolt SE: Best for Fingerprint Entry and Matter

On paper the Bolt SE is the most capable lock in this group, and at a mid-range price it stays the easiest value argument to make during the sale. Seven ways in: fingerprint, passcode, app, web portal, shared eKey, voice and two mechanical keys.

The fingerprint reader holds up to 50 prints and the keypad holds up to 50 codes, which comfortably covers a big family plus regular visitors. Battery life is claimed at up to 18 months, enabled by Thread low-energy mesh networking, with real-time low battery alerts in the app.

Matter over Thread is the part that makes this list different. Instead of being locked to one voice assistant, the lock can show up in Apple Home and other Matter apps, and the self-healing mesh automatically reroutes the connection if one device drops off.

Good to know: the built-in radio is 2.4 GHz only. If your router is 5 GHz-only, or the router sits far from the front door, the connection will struggle. Reviews also note the door sensor is not included, so the lock cannot report whether the door is open.

Set against the eufy Smart Lock C220, which also has fingerprint and built-in WiFi, the Bolt SE wins on flexibility: more entry methods, longer battery life, a stated IP65 rating and a standards-based radio. The eufy is simpler but lives inside the eufy app.

Warranty here is lifetime mechanical with 18 months of electronics, and the body is a zinc alloy rated ANSI/BHMA certified. The install is a ten-minute screwdriver job.

3. Sifely Smart Lock S: Best for Guest Codes and Rental Doors

The Sifely Smart Lock S earns its place on short-term rental access. You generate a temporary PIN in the app or web portal, hand it to a guest, and read the access log afterwards without ever meeting anyone at the door.

Unlike the deadbolts, this is a handle-and-keypad lock with five entry methods: fingerprint, PIN, app, key fob or card, and a physical key. The reversible handle means one box covers both door handings, and most standard doors take it with no extra drilling.

The interior privacy button is the sleeper feature for ordinary homes. Press it and every electronic entry method is disabled while you are inside, so a curious teenager or a guest cannot buzz themselves in.

Skip it if you need remote access out of the box. Full remote unlocking, PIN generation and Alexa or Google voice control all require the separately sold Sifely WiFi Gateway, which changes the cost of the whole setup.

Owners also report this lock is not engineered for a fully exposed door, with one reviewer citing water ingress after heavy rain, and that the in-app speaker is quiet even at maximum volume. Compared with the ULTRALOQ Bolt SE, you give up the built-in WiFi and the long battery figure; you get a lever handle, a privacy button and the easiest guest workflow in the group.

4. eufy Smart Lock C220: Best for One-Second Entry

The eufy Smart Lock C220 is a fingerprint deadbolt that does one thing extremely well: reading your finger fast. Touch the sensor and it unlocks in under a second, and the self-learning recognition gets more accurate as it collects touches.

Six unlock paths are supported, including an Apple Watch and voice through Alexa or Google Assistant, plus the app, a keypad code and a physical key. WiFi is built in, so remote control through the eufy Security app works without a bridge.

It drops into most standard deadbolts in about 15 minutes with no drilling, and bores under 54mm fit once the included spacer is removed. Certification is BHMA Grade 3 after more than 100,000 lock cycles, with IP53 water resistance rated from -22F to 158F.

The trade-off is ecosystem. The lock is built for the eufy Security app and pairs with eufy video doorbells, and that matters for anyone running Home Assistant or another local system. Compared with the ULTRALOQ Bolt SE, you get faster reads and a simpler app and you lose Matter, the seven entry methods and the 18-month battery claim.

Good to know: the fingerprint reader sometimes needs several registration scans before a finger sticks, and the eight-AA pack is a chunky thing to keep on hand. The low battery notification arrives in the app. This is also the pick for a dog-walker or family entry where speed at the door matters more than long battery life.

5. Aqara Smart Lock U100: Best for Apple Home Key

The Aqara Smart Lock U100 is the pick if you tap your iPhone or Apple Watch on the door and it opens, even when your phone is out of power. That is Apple Home Key, and it works because the credential is stored in the wallet rather than relayed from the phone.

Fingerprint storage holds up to 50 prints, and the biometric data stays on the lock itself under AES encryption. One-time local visitor codes can be created without the app for a neighbour or a dog walker.

The gyroscope-driven auto-lock earns its place. It engages after the door closes rather than on a timer, and a Do Not Disturb mode mutes the lock sounds for set periods if you have light sleepers.

Here is the catch, and it is a real one. There is no built-in WiFi. Remote password configuration and third-party ecosystem control both need an Aqara Zigbee 3.0 hub, and sharing Apple Home Keys with guests needs an Apple Home Hub. The NFC card is not in the box either.

That reliance on other hardware is why this lock carries the lowest average rating in the group at 4.1 stars. Owners with the hub and an Aqara setup describe it as excellent. Buyers outside that ecosystem describe the hub requirement and missing card as deal breakers. Compare with the ULTRALOQ Bolt SE if you want Matter and fingerprint in one self-contained unit.

Weather-wise it holds up well: IP65, a zinc alloy body, and a BHMA Level 3 equivalent standard with operation from -31F to 151F. Four AA cells run up to eight months, and a USB-C port handles emergency charging.

6. Tapo Smart Lock DL110: Best for Large Households

The Tapo Smart Lock DL110 stores 100 fingerprints and reads them in 0.42 seconds, even with wet or dirty hands. For a house with several adults, a partner, three teenagers and a regular sitter, that capacity is the whole pitch.

It also comes with a removable rechargeable battery pack rated for a year of use, charged over USB-C, plus a second USB-C port on the interior for emergency external power. That removes the annual AA ritual that owners complain about elsewhere in this list.

Operation is notably quiet, which owners mention more than almost anything else. The rubber gaskets on both sides cut movement and protect the door finish, and the install is a 10 to 15 minute screwdriver job on standard 2-1/8 inch deadbolt holes.

Best of all for traditionalists, the key cylinder is Schlage SC1 compatible and rekeyable, so you can match it to the rest of your doors and use your existing keys.

The friction here is the keypad, which stays completely invisible until the screen is touched, and a doorbell button under the keyway cap that owners find hypersensitive and easy to bump while operating the lock. There is also no local API or Matter support, so codes and fingerprints are registered on each unit individually and managed through the Tapo cloud.

That is why this is not the top pick despite sharing the highest rating in the group. If you want the fastest fingerprint and the longest battery story, this one is hard to argue with. If you want a visible backlit keypad for guests, look at the Philips WiFi Keypad Deadbolt instead.

7. Philips WiFi Keypad Deadbolt: Best for Doors That Need a Handle

The Philips WiFi Keypad Deadbolt solves a specific problem: your door has a lever handle, not a bare deadbolt. Two matching levers come in the box, so you do not end up with a keypad on one side of the door and a handle that does not match on the other.

Fingerprint entry reads in 0.3 seconds, the fastest figure in this group, alongside keypad, app and physical key backup. The passcode system is the flexible part: permanent, one-time, periodic and recurring codes cover a family, a cleaner on a weekly schedule and a guest for a weekend.

Good to know: auto-lock ships switched off and has to be turned on manually in the app, where you can set the delay anywhere from 0 to 180 seconds. On busy mornings a zero-second delay is the setting most owners land on.

WiFi is built in at 2.4 GHz, so no hub or bridge is needed, but the lock should sit within about 33 ft of the router. For a front door at the end of a long driveway or a rear garage door, that is the detail to check first.

Two smaller setup notes: batteries are not included and only standard 1.5V alkaline cells should be used, and the lock is set up for right-swinging doors by default, so a door that swings the other way needs a handing reset. With roughly 800 reviews this is the least battle-tested listing here, and the most likely reason to buy is the included lever set rather than the electronics.

8. Wyze Auto-Lock Bolt v2: Best for Wyze Camera Owners

The Wyze Auto-Lock Bolt v2 sits at the lower end of the fingerprint locks here and shares the highest average rating in the group. The scanner reads a finger in 0.5 seconds on scratch and smudge-resistant tempered glass, and the AI learning algorithm improves as it goes.

What arrives in the box matters on this one: eight AA batteries and two physical backup keys. The USB-C emergency port accepts a common power bank, so a flat lock is a two-minute problem rather than a locksmith call.

For anyone already running Wyze cameras, the standout feature is the doorbell integration. You can see a visitor on the live feed and unlock the door from the same screen, which answers the package-delivery problem neatly.

The auto-lock timer is configurable from 0 to 180 seconds, and it locks within roughly 5 to 10 seconds by default. Certification is BHMA Grade 2 with IP53 weather resistance and an anti-peep keypad.

The real drawback owners raise is that auto-lock does not check whether the door is actually closed, so a lock that thinks the door is shut can throw the bolt into an open doorframe. Quiet keypad beeps and a touchpad that does not backlight are the other repeated complaints, both of which matter more for hard-of-hearing users and for entering a dark porch. Compared with the eufy C220, you get a faster sensor and eight included batteries, and you give up the eufy app ecosystem.

9. Schlage Arrive WiFi: Best for a Physical Keypad

Every other fingerprint lock here hides its numbers until you touch the screen. The Schlage Arrive WiFi uses physical, all-weather silicone buttons that are backlit for low light, and owners single that out as the reason it feels better in the rain and better with wet hands.

It runs on four AA batteries, connects to WiFi without a hub, and handles up to 250 access codes with lock history and customisable notifications across multiple locks in one app. That is the largest code capacity of any lock on this list.

The Arrive also links with Alexa, Google Home, video doorbells and smart lighting for routines, and carries the same highest residential BHMA rating as the Encode. The install is screwdriver-only with interactive step-by-step instructions in the app, and it fits doors from 1-3/8 to 1-3/4 inches thick.

Skip it if you want fingerprint entry. There is no reader here at all, so a key, a code or a tap in the app is every option you get. That is the whole trade against the eufy C220 and the ULTRALOQ Bolt SE, both of which read a finger.

With around 220 reviews this is the least-reviewed listing in the group, and it has a couple of sharp edges. The inside lever is light metal that rattles and feels cheap when turned, and a minority of units failed to join WiFi even after troubleshooting, which meant a warranty return. A smaller existing deadbolt hole can also need a special tool to enlarge, and many locksmiths do not carry one.

A physical backup key comes in the box for dead batteries or a WiFi outage. The warranty is limited lifetime on mechanical and finish with three years on electronics, the same cover as the Encode.

10. Tapo Smart Lock DL100: Best for a Tight Budget

The Tapo Smart Lock DL100 is the cheapest lock on this list, and it gives up less than the price gap suggests. It has built-in WiFi for remote locking and real-time access alerts, so no hub is needed to use the app away from home.

The keypad is the part worth calling out. These are tactile, backlit buttons rather than a touch surface, so the numbers are visible in the dark, and you can enter your code between random digits to defeat shoulder surfing. Up to 200 customisable passcodes are supported, grouped in the app by person.

Battery life is the headline spec: up to 200 days in WiFi mode and up to 300 days in Bluetooth-only mode from four included AA batteries. A USB-C port handles emergency power, and a PIN attempt limiter locks the system after a set number of failed tries.

It fits standard 2-1/8 inch and 1-1/2 inch bores with no drilling, carries BHMA Grade 3 certification and IP54 weatherproofing, and links with Alexa, Google Home and Samsung SmartThings.

What you give up is fingerprint entry, which every other pick above this one has. Voice unlocking also means saying a PIN aloud, which several users find impractical. And the quoted 200-day figure applies to WiFi mode, so heavy remote use pulls that down noticeably.

For a back door, a garage entry or a rental unit where codes matter more than biometrics, that is a fair exchange. Compared with the Philips WiFi Keypad Deadbolt, you give up fingerprint reads and the included levers but gain a more established review record; compared with the Tapo DL110 in the same range, you get a visible keypad instead of a hidden one.

How to Choose Smart Locks During Prime Big Deal Days

Sale days push people toward whichever listing is loudest. A short framework for the five things that actually decide whether a smart lock works in your house will save a lot of that impulse.

Security Features and Locking Options

Look for a stated certification rather than a vague security claim. BHMA Grade 2 and Grade 3 are the common residential marks, and the Schlage Encode and Arrive carry the highest residential BHMA rating available. Also check what happens when someone forces the door: the Encode has a built-in alarm for door movement and forced entry, and the Tapo DL100 and Wyze Bolt v2 both add a PIN attempt limiter that locks the system after repeated failures.

Smart-Home Compatibility and Connectivity

Decide where the lock reports to before you buy. Locks with WiFi inside the housing, such as the Schlage Encode, eufy C220, Tapo DL110 and DL100, need no hub. Locks that rely on Bluetooth or Zigbee, such as the Sifely Smart Lock S and the Aqara U100, need a gateway or hub before remote access works at all. Two details catch people out: 2.4 GHz-only WiFi on the ULTRALOQ Bolt SE, Philips and Wyze units, and the Thread Border Router requirement for Matter features on the Bolt SE. If you are building out a hub-based setup, our guide to Matter smart home hubs covers what the standard needs.

Installation and Door Compatibility

Most of these locks are full replacements, not retrofits that keep your existing deadbolt. Before ordering, measure door thickness and the bore: the Schlage units fit 1-3/8 to 1-3/4 inch doors, the eufy C220 fits bores under 54mm once the spacer is removed, and the Tapo DL100 takes standard 2-1/8 and 1-1/2 inch bores without drilling. A smaller existing deadbolt hole may need enlarging with a tool many locksmiths do not carry. Installation times in the specs run from about 10 minutes to 25, and all of them are screwdriver jobs with no hardwiring.

Power Options and Battery Management

Battery claims vary more than any other number here, and the reason is the radio. Thread-based and Bluetooth-only modes stretch life dramatically: the ULTRALOQ Bolt SE claims up to 18 months, the Tapo DL100 claims up to 200 days on WiFi and 300 on Bluetooth, while WiFi-heavy deadbolts like the Schlage Encode sit at about six months. The Tapo DL110 is the outlier with a removable rechargeable pack rated for a year. Buy the lock that warns you before it dies, and keep the USB-C emergency port in mind for the models that have one. If you are also planning outside power work, our picks for outdoor smart plugs cover weatherproof power for other exterior gear.

Access Methods and Household Sharing

Count your entry methods against your household, not against the spec sheet. Fingerprint suits a family of four or five, and the Tapo DL110 holds 100 prints with 0.42-second reads. Shared PINs suit rentals and short-term visitors, which is why the Sifely Smart Lock S and the Philips deadbolt support temporary, periodic and recurring codes. Voice assistants cover packages and dog walkers, but unlock-by-voice usually means speaking a PIN. If several people will be managing access day to day, a wall panel or a shared dashboard makes more sense than a phone-only app, and our roundup of smart home control panels covers the options.

How to Shop Smart Lock Deals During the Sale

Smart lock listings change during the event, so check the model number in the specifications block before you click through. The Schlage Encode BE489WBCEN622 and the Arrive BE459WBCAM619 are different locks with similar names, and the Tapo DL100 and DL110 differ in fingerprint reader and battery type entirely. Look at what is in the included components line, because some boxes include batteries and keys and others, such as the Philips deadbolt, leave them out. Check who sells and ships the listing, and prefer a new unit over a renewed one for something drilled into your door. Most offers need a Prime membership, and they change through the event.

Before you buy, confirm six things:

• Door thickness and bore diameter match the listing’s fit range
• Radio type, whether it is built-in WiFi, Bluetooth, Zigbee or Thread
• Whether the ecosystem you already run supports the lock before you buy another hub
• That a physical backup key ships in the box for every door you cannot afford to lock out of
• Whether the entry method matches your household, fingerprint for family, codes for guests
• Low battery warnings and an emergency power port for a lock that sits far from the router
