12 Smart Lock Deals: Prime Big Deal Days (October 2026 Sale)

The Schlage Encode WiFi Deadbolt tops our list of smart lock deals for Prime Big Deal Days, thanks to its built-in Wi-Fi, BHMA-certified build, and Alexa and Google Home voice control straight out of the box. The ULTRALOQ Bolt SE is the strongest pick for anyone invested in Matter over Thread, while the Tapo DL110 stands out if a fast fingerprint reader and quiet deadbolt are at the top of your list. These three are the models worth watching when the sale opens on October 6-7, 2026.

Smart locks tend to be one of the deeper-discount categories during Amazon's October event, so this list focuses on the locks that earn their space at the door regardless of price. We compared 12 models across connectivity, access methods, install complexity, and ecosystem fit, and pulled owner-review themes to flag the trade-offs buyers actually report. Most offers on this list need an Amazon Prime membership, and pricing can shift through the event, so the buttons below always show the current number.

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

Smart Lock Deals: Prime Big Deal Days Compared (October 2026)

How We Chose

Each lock below was compared on the specs that actually change a smart-home install: connectivity protocol, lock type, access methods, power source, door compatibility, ecosystem support, warranty, and security rating. We cross-checked owner ratings and themes from thousands of reviews, and we kept the list focused on locks from brands with a real track record on Amazon. Data was reviewed in October 2026, and we focused the picks on models worth watching during the sale window rather than only listing every option on Amazon.

1. Schlage Encode: Best Overall Smart Lock to Watch

The Schlage Encode wins the top spot because it covers the basics so well that most shoppers will never feel locked in. Built-in Wi-Fi removes the hub question entirely, so setup is a Schlage Home app account and a screwdriver. The Century style in matte black is the version most owners post about, and the fingerprint-resistant keypad has held up well to weather in owner photos.

100 access codes and the one-touch locking button are the everyday wins reviewers call out most. The built-in alarm sits quietly until a door sensor trips, and codes are easy to schedule from the app for short-term rental use cases where you want them to auto-expire.

The Encode trades fingerprint and Matter for a more proven Wi-Fi experience and the BHMA highest residential rating. Skip the Encode if biometric unlock or full Matter support is the priority, and reach for the ULTRALOQ Bolt SE instead.

The package includes installation hardware and a Snap n Stay design that keeps the lock on the door while you connect the cable. For most standard US doors this is a true retrofit with no drilling.

2. ULTRALOQ Bolt SE: Best for Matter over Thread

Matter over Thread is the headline feature, and the Bolt SE delivers it without giving up built-in Wi-Fi for remote access. Run it through an Apple Home or SmartThings hub today and the app control still works without a separate bridge. The fingerprint sensor stores up to 50 prints, and keypad codes match that count.

Reviewers point to the 18-month battery life as a real-world improvement over most Wi-Fi locks. The IP65 rating and zinc body hold up to weather in coastal install photos, and the 10-minute install matches the marketing. Fingerprint read speed is competitive with the Tapo DL110, though the Tapo still edges it out.

Skip this lock if you do not already own a Matter-compatible hub, because Thread needs a border router to extend past Bluetooth range. The Kwikset Halo is the cleaner Wi-Fi-only alternative, and the Aqara U100 is the better Apple Home Key pick.

The package includes two emergency keys and the install kit. The door sensor is sold separately, so factor that in if open or close detection matters.

3. Tapo DL110: Best Fingerprint Performance

The 0.42-second unlock is the fastest claim across the 12 locks, and reviewers confirm the sensor does not get sluggish in cold weather the way some earlier fingerprint readers did. The rechargeable battery is rated for a full year on a charge, which removes the swap-cells routine of older locks.

Setup runs through the same Tapo app most TP-Link smart home shoppers already use, and the lock pairs quickly over Bluetooth before Wi-Fi takes over. Owners mention that the deadbolt motor is noticeably quieter than the Encode and the ULTRALOQ models, which matters in attached homes or thin interior doors. The BHMA Grade 2 certification is a step above some of the budget picks.

The DL110 wins on fingerprint speed and battery life but loses on app openness when stacked against the eufy C220. The C220 plays more easily with Apple Watch, while the DL110 leans on the Tapo app for routines. Pick quiet operation and a rechargeable pack, and the DL110 is the winner.

The keypad stays hidden until you tap it, which is a clean look but means no glance-and-go at night. The proprietary battery pack charges through USB-C, so you are not stuck hunting for AAs.

4. eufy Smart Lock C220: Best for Apple Watch Users

Apple Watch unlock tops the list of reasons to shortlist the eufy C220. Six unlock methods cover fingerprint, app, keypad, physical key, Apple Watch, and voice, and the self-learning AI is the kind of feature that actually gets better after a few weeks of use. Built-in Wi-Fi keeps the hub question off the counter.

Reviewers highlight fingerprint read under one second and BHMA Grade 3 certification as solid for the price. The 15-minute install claim lines up with owner reports, and eight AAs in the box mean no day-one trip to the store. The aluminum body feels lighter than the Encode in the hand.

The Wyze Bolt v2 is the stronger pick if you live in the Wyze camera world, but the C220 is the more flexible pick for cross-ecosystem use. If Apple Watch unlock is not a priority, the Wyze wins on raw fingerprint speed.

The lock ships with two keys, eight AAs, and the mounting plate in the box. Measure your door bore first if it is not a standard 2-1/8 inch cut.

5. ULTRALOQ U-Bolt WiFi: Best with Door Sensor Included

The door sensor in the box is the headline, and it makes a real difference. Anyone who has had a smart lock that auto-locked while the door was still open knows that sensor is the line between a feature you trust and one you turn off. Geofencing auto-unlock is the closest thing to hands-free entry on this list.

ANSI/BHMA Grade 1 is the strongest residential rating across the 12 picks, and reviewers point to it as the reason they trust the lock on a rental property. Seven unlock methods cover passcode, app, eKey, voice, web portal, auto-unlock, and two mechanical backup keys. IP65 weatherproofing matches the Bolt SE.

The U-Bolt trades Matter support for the included door sensor and Grade 1 certification. The Bolt SE is the better Matter-ready pick, but for households that do not need Matter yet, the U-Bolt is the all-around winner.

The U-Bolt installs on a standard 2-1/8 inch door bore and pairs with Alexa, Google Assistant, and SmartThings out of the box.

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

Tapping an iPhone or Apple Watch against the lock through Apple Home Key is the most seamless front-door experience on this list, and the fingerprint reader sits beside it as a reliable backup. The gyroscope-based auto-lock waits for the door to actually close before engaging, which is the practical win over a plain timer.

Owners rate fingerprint performance close to the Tapo DL110, and the IP65 weather rating matches the ULTRALOQ locks. The USB-C emergency charging port is the cold-weather safety net reviewers mention most. BHMA Level 3 certification is a step behind Grade 1, but typical for this category.

The Yale Assure Lock 2 wins on auto-unlock and DoorSense, while the Aqara wins on Home Key tap-to-unlock. For households that live on HomeKit, the U100 is the clear pick.

The lock needs an Aqara Zigbee 3.0 hub for full features. An existing M2 or M3 hub drops this lock right into the setup with no extra hardware.

7. Kwikset Halo: Best for High Code Capacity

250 user codes is the highest capacity on this list, and that single number is why the Kwikset Halo earns its spot. Offices, multi-family properties, and households with a long guest list need that room without juggling workarounds. SmartKey rekey technology lets you rekey the physical lock to match an existing Kwikset key without a locksmith.

Reviewers call out the touchscreen as responsive in cold weather and the intrusion detection alerts as a useful extra layer. The Wi-Fi connection runs straight to your router, so there is no hub to mount. App registration is required, which is worth knowing up front.

The Halo trades 100 codes for 250 and a fingerprint-resistant keypad for a touchscreen compared with the Schlage Encode. Most homes are better served by the Encode, but the Halo wins when code capacity is the priority.

The package includes four AAs, a SmartKey tool, two keys, and the mounting hardware. The matte black finish is the version most owners post about.

8. Wyze Auto-Lock Bolt v2: Best Budget Fingerprint Pick

The highest-rated lock on this list by average score, and it lands at the budget end of the pricing spread. The 0.5-second fingerprint unlock is faster than the eufy C220 and Aqara U100, and the AI learning scanner is the kind of feature that gets noticeably better in the first month. Eight AAs in the box drive the 8-month battery claim.

Integration with the Wyze app is the hook for shoppers already running Wyze cameras and sensors. The USB-C emergency power port means a dead battery is a 10-minute problem, not a lockout. BHMA Grade 2 certification matches the Tapo DL110 and ULTRALOQ Bolt SE.

The Bolt v2 is the better pick if you live in the Wyze ecosystem and want the lowest price compared with the Tapo DL110. The DL110 wins on rechargeable battery and quiet operation, but it costs more.

The auto-lock uses a timer rather than a door sensor, so it will lock on a door that is propped open. The keypad lights up only on touch.

9. Yale Assure Lock 2: Best for Auto-Unlock Convenience

Yale's geofencing auto-unlock is the headline, and DoorSense tells you in the app whether the door is actually closed before the lock engages. Unlimited scheduled codes cover rental and dog-walker use cases where you want codes that turn on and off on their own.

HomeKit support is the smoothest in the Yale lineup, and the included DoorSense sensor is a real-world safety upgrade over a timer-only auto-lock. The Wi-Fi smart module is included in the box, which removes the upcharge that older Yale models used to carry.

The Assure Lock 2 trades Home Key and fingerprint for auto-unlock and DoorSense compared with the Aqara U100. If tap-to-unlock matters more than hands-free approach, the Aqara wins.

The Black Suede finish is the version most reviewers post about. The lock needs four AA cells, and reviewers suggest name-brand batteries for the longest life.

10. Philips Wi-Fi Deadbolt: Best for Multiple Access Methods

Five unlock methods on a lock that still comes in under most budgets is the Philips pitch. App, passcode, fingerprint, physical key, and voice cover the everyday ways people actually open a door. Built-in Wi-Fi keeps the install simple and the router count low.

Owners call out the 100-code capacity and the anti-peeping password feature as the everyday wins. Real-time activity alerts push to the app when codes are used, which is useful for rental properties. The Away Mode adds a stricter lockout policy when you leave for a trip.

The Philips adds a fingerprint reader at a similar price to the Schlage Encode. The Encode wins on BHMA rating, while the Philips wins on access methods.

Batteries are not included, so plan to pick up four AAs at the same time. The matte black finish matches most front door hardware.

11. TEEHO TE012W: Best Affordable Fingerprint Lock

The most budget-friendly fingerprint lock on this list, and it earns the slot by pairing a low price with the security basics that matter. BHMA Grade 3 certification, anti-peeping password, and break-in detection with a 3-minute lockout are not features you usually find at this end of the price spread. Eight AAs in the box run the lock longer than the standard four-cell locks.

Install is straightforward on a standard door, and the fingerprint read is reliable in mild weather according to reviewers. The 20-fingerprint limit is the most common complaint, but for a single-family home that is not a real constraint. 100 passcodes cover guest access for most households.

The TEEHO is the better pick if you want the lowest price with fingerprint and passcode support compared with the Wyze Bolt v2. The Wyze wins on fingerprint speed, AI learning, and battery life, but it costs more.

The lock fits standard US door bores and ships with two backup keys. IP55 weatherproofing is a step below the IP65 of the ULTRALOQ locks, so consider a covered install for full weather exposure.

12. Tapo DL100: Best Keypad-Only Smart Lock

No fingerprint reader is not a downgrade. Fewer sensors, longer battery life, and a tactile button feel that some shoppers prefer over a smooth touchscreen define this lock. The 200-day Wi-Fi battery rating is the longest on this list by a wide margin, and 300 days in Bluetooth-only mode is even longer.

Tactile button feedback and the deep 200-code capacity are the features owners rate highest. Setup runs through the Tapo app, the same one the DL110 uses, so households already invested in Tapo hardware get a familiar experience. BHMA Grade 3 certification matches the TEEHO and eufy locks.

The DL100 trades fingerprint and a rechargeable battery for tactile keys and much longer cell life compared with the Tapo DL110. If fingerprint unlock is not a priority, the DL100 is the more reliable pick.

The keypad stays dark until touched, which keeps the front of the lock clean. The IP54 weatherproof rating is a step below the IP65 of the ULTRALOQ models, so sheltered installs are best.

How to Choose a Smart Lock During Prime Big Deal Days

Connectivity standard (Wi-Fi, Bluetooth, Matter, Thread, Z-Wave, Zigbee)

Connectivity is the single biggest decision in this category. Wi-Fi locks like the Schlage Encode and Kwikset Halo skip the hub but trade battery life for remote access. Bluetooth-only locks stretch battery life to almost a year but lose remote control when you are away from home. Matter over Thread locks like the ULTRALOQ Bolt SE are the future-proof pick, but only if you already run a Matter-compatible border router. Zigbee locks like the Aqara U100 need the brand's own hub to unlock their best features.

Lock type and fit for your door

Most of the locks on this list are full-deadbolt replacements, which means they take the place of your existing deadbolt rather than fitting over it. Check your door's backset (usually 2-3/8 or 2-3/4 inches) and bore diameter (usually 2-1/8 inches) before you buy. Standard US doors are covered by every lock above, but older homes sometimes need an adapter plate.

Power source and battery life

AA cells are the most common power source on this list, and reviewers consistently say battery life lands at 60 to 75 percent of the manufacturer's claim when Wi-Fi is on full time. The Tapo DL110 is the standout with a 1-year rechargeable pack, and the Tapo DL100 stretches to 200 to 300 days on AAs. ULTRALOQ's Bolt SE claims 18 months, which is the longest in the AA group.

Install method and door compatibility

Every lock on this list is a screwdriver retrofit on a standard US door. The Schlage Encode, eufy C220, and Tapo DL110 are the easiest installs based on owner feedback. The ULTRALOQ U-Bolt WiFi includes a door sensor, which makes the install slightly more involved but solves the open-door auto-lock problem.

Smart-home ecosystem and app features

Match the lock to the smart home you already run. Apple Home Key users get the most from the Aqara U100. Alexa and Google Home shoppers are covered by the Schlage Encode, Kwikset Halo, Philips, and Tapo DL100. SmartThings owners get the broadest support from the ULTRALOQ locks and the Tapo DL100. Matter-ready shoppers should focus on the ULTRALOQ Bolt SE.

Security, warranty, and build

ANSI and BHMA certifications are the shorthand for residential security ratings, and they map roughly to Grade 1 (commercial grade), Grade 2 (strong residential), and Grade 3 (standard residential). The ULTRALOQ U-Bolt WiFi is the only Grade 1 lock on this list. Kwikset backs the Halo with a lifetime mechanical warranty, which is the strongest warranty on the list.
