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

The Schlage Encode Smart WiFi Deadbolt is the smart lock we keep coming back to during Amazon’s Prime Big Deal Days sale, thanks to its built-in WiFi, 100 access codes, and Alexa and Google voice control in one Schlage-built package. If you want a fingerprint reader at a budget, the TEEHO TE002 delivers fast 0.3-second fingerprint recognition and a 365-day battery life, while the TEEHO TE001 sits at the bottom of the price ladder for buyers who only need a keypad deadbolt with no WiFi required.

Amazon’s Prime Big Deal Days runs October 6-7, 2026, and most offers need a Prime membership (a free trial counts). Prices change through the event, so check each listing for the current figure when you shop.

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

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

How We Chose

We compared these 10 smart locks on the specs that matter when you shop during the sale: lock type (keypad, biometric, or full replacement deadbolt), connectivity (built-in WiFi, Bluetooth, Matter over Thread, or a separate hub), voice and smart home compatibility, keypad and fingerprint features, battery life, BHMA and ANSI security ratings, and what owners say after living with the lock. Data was checked in October 2026 from the live Amazon listings and current owner reviews.

1. Schlage Encode WiFi: Best for Built-In WiFi and Voice Control

The Schlage Encode is the easiest pick for someone who wants the lock to behave like an appliance: install it, give every family member a code, and forget about it. Built-in WiFi and Bluetooth sit inside the deadbolt, the Schlage Home app handles up to 100 access codes, and Alexa and Google Home take voice commands without an extra bridge. The keypad is fingerprint-resistant, the alarm triggers on forced entry, and a one-touch lock from outside is handy for kids who walk out without their keys.

Most reviewers finish the install in well under an hour with a single screwdriver, and the limited lifetime mechanical warranty is a long safety net for a lock that gets used thousands of times a year. The trade-off that comes up most is battery life at roughly 6 months on the included 4 AA cells, and a few owners have seen WiFi drops after a router or modem swap. For a household that wants one less thing to fuss with, the Encode usually lands in the middle between the bare-bones TEEHO TE001 and the more hub-heavy Aqara U100.

• Built-in WiFi means no extra hub on the shelf.
• 100 access codes cover most households and small offices.
• BHMA highest residential security rating for peace of mind.
• Physical backup key for the day the batteries die.

The Encode uses a physical backup key, so a dead battery or a lost phone does not lock you out. Pair it with auto-lock on a 30-second delay and a code for the dog walker, and the lock is essentially hands-off after the first week.

2. TEEHO TE002: Best for Fingerprint on a Budget

For a fingerprint reader, a keypad, and a budget price in the same deadbolt, the TEEHO TE002 is the lock most buyers land on during October sales. The 0.3-second fingerprint sensor stores 20 prints, the keypad holds 20 more codes, and the auto-lock timer is configurable from 10 to 99 seconds. There is a silent mode for late-night entries and an away mode for long trips.

The install goes in minutes with no drilling, and the IP54 rating holds up at front and back doors. Reviews call out fast fingerprint recognition as the standout, and the 365-day battery claim lines up with what most people see in real use. The trade-off: no built-in WiFi, so remote unlock needs the separate TEEHO gateway, and a few reviewers mention the fingerprint reader occasionally needs a second try when fingers are wet or cold.

• 0.3-second AI fingerprint reader with 20-print storage.
• 365-day battery on 4 AA cells, so you barely think about it.
• IP54 weather rating for exposed front doors.
• Anti-peep passcode and one-time PIN for visitors.

Two SC1 backup keys ship in the box, the warranty runs 2 years, and the lock works on most standard US doors. For a renter who does not want to drill, it is one of the easiest fingerprint smart locks to put on and take off.

3. TEEHO TE001: Best for Simple Keypad Replacement

The TEEHO TE001 is what you reach for when you want a basic keypad deadbolt that just works, with no apps, no hubs, and no accounts. The keypad holds 20 user codes and a one-time PIN for visitors, the auto-lock timer is adjustable, and holding any key for 2 seconds locks the door from outside. The keypad is backlit and weather-sealed to IP54.

It is the cheapest lock on this list and currently sits at #1 in Amazon’s Deadbolts ranking. Reviewers consistently praise the simple install and the reliable keypad. The trade-offs are obvious: no WiFi, no Bluetooth, no fingerprint, and no remote access. For a guest house, a garage entry, or a back door that does not need smart features, that is exactly what most buyers want during the sale.

• 20 access codes plus a one-time PIN for visitors.
• 365-day battery on 4 AA cells.
• IP54 weather rating for an exposed front or back door.
• Auto-lock from 10 to 99 seconds, configurable on the keypad.

The lock needs a one-time reset on first use to detect door handing, and the low-battery indicator flashes red below 15%. The 2-year warranty and lifetime customer support from TEEHO are a nice safety net for a budget pick.

4. ULTRALOQ Bolt SE: Best for Matter and Apple Home

For an Apple Home or Matter household that wants the lock to drop straight into an existing setup, the ULTRALOQ Bolt SE is the most flexible lock on this list. Matter over Thread handles Apple Home, built-in WiFi handles everything else, and the 7-in-1 unlock list covers fingerprint, passcode, smartphone app, web portal, eKey, voice, and two mechanical keys. Storage is generous: 50 fingerprints and 50 passcodes.

Reviewers highlight 18 months of battery life on the included cells, and the IP65 zinc alloy body handles rain and cold. The 10-minute install is one of the easier ones on this list. The trade-offs: a Matter over Thread hub is needed for full functionality, a few users have seen connection drops, and the lock does not ship with a door sensor.

• 7 unlock methods from fingerprint to voice to eKey.
• Matter over Thread for native Apple Home, Alexa, Google.
• 18 months on the included batteries, the longest on this list.
• IP65 weather rating and ANSI/BHMA certification.

ANSI/BHMA certification covers this lock, the warranty is lifetime mechanical and 18 months electronic, and the fingerprint sensor is glove-friendly. For a smart home that runs HomeKit, Alexa, and Google, it is one of the easiest picks on this list to integrate.

5. Sifely S: Best for Airbnb and Rental Hosts

A short-term rental is one of the hardest tests for a smart lock, and the Sifely S is built for it. The lock reads fingerprint, keypad, app, key fob, or a physical key, so guests and cleaners can use whatever is easiest. The reversible handle fits left and right doors, the install is minutes with no drilling, and the Sifely app generates guest codes on the fly.

Owners running short-term rentals say the lock survives the constant code turnover and the included keys and key cards help. Reviews highlight the easy install and the solid fingerprint speed. The trade-offs reviewers mention: the WiFi gateway is sold separately for full remote access, the touchscreen can be slow to wake, and the weather seal is the part to watch in exposed entries.

• 5 unlock methods, including a fob for guests without phones.
• Airbnb-ready with one-time guest codes from the app.
• Reversible handle fits both left- and right-hinged doors.
• Auto-lock and one-touch locking from the keypad.

The warranty is one year and the Sifely app keeps an unlock record you can hand to a property manager. For hosts who need remote codes for guests, plan on the gateway add-on; for hosts who hand out fobs in person, the lock alone is enough.

6. Kwikset Halo: Best for Many Users and High Traffic

Few locks on the market can hand out 250 access codes, and that is the reason the Kwikset Halo is on this list. The capacity covers a church, a small office, a property manager with multiple units, or a big family with a code per person. Built-in WiFi means no bridge, the geofencing auto-unlock fires as you walk up, and Alexa and Google Home control voice commands.

Most owners report the install is fast and the activity history in the app is detailed. Reviews call out the Kwikset app for solid notifications. The trade-offs are real: several reviewers say battery life runs closer to 3 months than 6, the touchscreen takes a beat to wake, and the Kwikset account requirement is a small friction point. The 3.9 rating reflects that mix.

• 250 access codes is the highest in this roundup.
• Built-in WiFi with no bridge to install.
• Geofencing auto-unlock for hands-free arrivals.
• UL Listed and Grade AAA certified for the security-conscious.

The lock fits doors 1-3/8 inch to 1-3/4 inch thick, the warranty is lifetime mechanical and finish plus 1 year on electronics, and the Kwikset SmartKey tool rekeys the lock to match an existing Kwikset key. For high-traffic doors during the sale, it is one of the easiest large-code locks to set up.

7. eufy C220: Best for Fast Fingerprint Recognition

For fingerprint speed, the eufy C220 is the fastest reader on this list and one of the fastest in the category. The self-learning AI sensor unlocks in under a second, and the lock has six ways in: fingerprint, app, keypad, physical key, Apple Watch, and voice. Built-in WiFi means no bridge, and the 8-month battery life on 8 AA cells is one of the better runs on this roundup.

Most owners report the install in about 15 minutes with no drilling, and the unusual-attempt alarm gives extra peace of mind. Reviews praise the fingerprint speed and the BHMA Grade 3 rating. The trade-offs: it works best in the eufy ecosystem, there is no HomeKit support, and the price is higher than the TEEHO TE002 if fingerprint is all you need.

• Self-learning AI fingerprint reads in under a second.
• 6 unlock methods including Apple Watch and voice.
• 8-month battery on 8 AA cells, no bridge required.
• IP53 weather rating and BHMA Grade 3 certification.

The operating range is -22 to 158 degrees Fahrenheit, the IP53 rating handles rain, and Apple Watch unlock is a nice extra for owners who do not want to fish a phone out at the door. For an eufy household, the integration story is the real win during the sale.

8. Yamiry YR01: Best for Landlords and Property Managers

For a small landlord or a property manager with a few units, the Yamiry YR01 is the most app-friendly lock at a budget. The lock reads fingerprint, Bluetooth app, passcode, key fobs, mechanical keys, and Alexa voice (with the gateway), and the reversible handle fits left and right doors. The app generates one-time passcodes remotely and keeps an unlock record for each entry, which is the bread and butter of rental management.

Owners running small portfolios report the quick 10-minute install and the easy fob handoff to tenants. Reviews highlight the access management and the reversible handle. The trade-offs: the WiFi gateway is sold separately for full remote features, the app could be cleaner, and a few users have seen the lock drop off WiFi.

• 6 unlock methods including fingerprint and two fobs in the box.
• Remote one-time passcode generation from the app.
• Unlock record tracking for tenant handoff.
• Reversible handle fits both left- and right-hinged doors.

The lock fits most standard American wooden front doors, the fobs are useful for tenants who do not want to remember a code, and the 2 mechanical keys cover the inevitable lockout. For a duplex or a small multi-unit, the remote passcode feature is the differentiator.

9. Aqara U100: Best for Apple Home Key

For an Apple household, the Aqara U100 is the lock that turns the front door into a one-tap experience. Apple Home Key is the headline: hold an iPhone or Apple Watch near the lock and it unlocks, no Face ID or app launch required, and it even works when the phone is out of battery. The fingerprint reader handles up to 50 prints, the keypad supports one-time local passwords, and the Aqara Home app generates remote passwords when paired with an Aqara Zigbee 3.0 hub.

Owners in Apple households say the Home Key experience is what makes this lock worth the price, and the USB-C emergency charging port is a real backup plan. Reviews highlight the 8-month battery life and the IP65 weather resistance. The trade-offs: the Aqara hub is needed for full remote features, the NFC card is sold separately, and Zigbee is the protocol for the smart home side.

• Apple Home Key unlocks with iPhone or Apple Watch, even when the phone is dead.
• Up to 50 fingerprints and remote passwords via the Aqara hub.
• USB-C emergency charging port for a dead AA set.
• IP65 weather rating and BHMA Level 3 compliance.

The lock runs from -31 to 151 degrees Fahrenheit, the AES-encrypted fingerprint data stays on the lock, and the gyroscope-based auto-lock only fires when the door is actually closed. For a deep Apple household, this is the lock to watch during the sale.

10. ULTRALOQ U-Bolt: Best Grade 1 Certified Lock

For a security-first buyer, the ULTRALOQ U-Bolt is the only lock on this list with ANSI/BHMA Grade 1, the highest residential grade. The zinc alloy body is solid, and the door sensor that ships in the box tells you whether the door is actually closed, not just whether the bolt is thrown. Built-in WiFi handles remote control, the auto-lock fires when the door closes, and auto-unlock triggers as you walk up with your phone.

Most owners report the install is fast and the 50 passcodes cover most households. Reviews call out the door sensor as a real differentiator. The trade-offs: a few users have seen WiFi connectivity drops, the radio is 2.4 GHz only, and firmware updates have been rough for some owners. The 18-month electronic and lifetime mechanical warranty covers most of what could go wrong.

• ANSI/BHMA Grade 1 is the highest residential security rating.
• Door sensor included for real open/close status.
• Auto lock and auto unlock with the included WiFi.
• Works with Alexa, Google Assistant, and SmartThings.

The IP65 weather rating covers most installs, the lockout mode is useful for travel, and the included 4 AA batteries get you through about 8 months. The door sensor is the kind of feature that pays for itself the first time you wonder whether the front door is actually closed.

How to Choose Smart Locks During Prime Big Deal Days

Smart lock shopping during a sale is mostly about matching the lock to your door, your household, and your smart home setup, then letting the price do the rest. These are the factors that decide which of the 10 locks above is worth watching for you.

Door compatibility and what your door needs

Most US exterior doors are standard 1-3/8 inch to 1-3/4 inch thick with a 2-1/8 inch bore hole, and every lock on this list fits that. Check the backset (2-3/8 inch or 2-3/4 inch), the handing (left or right hinge), and whether you have an existing deadbolt to replace. The TEEHO TE001 and TEEHO TE002 ship with adjustable latches for the most common backsets, and the Kwikset Halo explicitly fits the 1-3/8 to 1-3/4 inch range. For thicker doors or non-standard setups, look for the lock’s compatibility chart before you commit during the sale.

Lock type: keypad, biometric, or full replacement

Keypad-only locks like the TEEHO TE001 and the Schlage Encode are the simplest swap. Biometric deadbolts like the TEEHO TE002, the ULTRALOQ Bolt SE, the eufy C220, and the Aqara U100 add a fingerprint reader. Full replacement deadbolts swap the entire interior and exterior assembly, while retrofit options keep your existing deadbolt and add a smart module on the inside. For renters, retrofit is the safer call; for homeowners, a full replacement usually fits better and looks cleaner.

Connectivity and smart home compatibility

Built-in WiFi (Schlage Encode, Kwikset Halo, eufy C220, ULTRALOQ U-Bolt) means no extra hardware. Bluetooth-only locks (TEEHO TE001, TEEHO TE002 by default) need a separate gateway for remote access. Matter over Thread (ULTRALOQ Bolt SE) and Zigbee (Aqara U100) need a hub or border router but drop into Apple Home, Alexa, Google Home, and SmartThings more cleanly. If your home already runs on one ecosystem, pick the lock that speaks its language.

For households that mix Apple Home with Alexa or Google, a lock that supports Matter or works as a native device in both saves a lot of app juggling. Some parents also use kids smart watches with GPS to manage who is at the door, and that same ecosystem thinking applies to the smart lock.

Keypad, access codes, and guest access

Most locks on this list store 20 to 250 codes. The Kwikset Halo leads at 250, the Schlage Encode at 100, the ULTRALOQ pair at 50. For a family, 20 to 50 is plenty. For an Airbnb or a multi-unit landlord, more is better, and one-time PIN codes for visitors (TEEHO TE001, Aqara U100) keep the master code safe. Fingerprint storage scales similarly: 20 on the TEEHO TE002, 50 on the ULTRALOQ Bolt SE and Aqara U100.

For households that hand out codes to babysitters, dog walkers, or visiting grandparents, the TEEHO TE001 and Aqara U100 both support one-time PINs, which is a nice middle ground between a permanent code and a physical key. The same idea shows up in cabinet locks for babyproofing, where temporary access matters more than permanent security.

Voice, app control, auto-lock, and notifications

Alexa and Google Home work with most locks here, while Apple Home is best served by the Aqara U100 and the ULTRALOQ Bolt SE. The Kwikset Halo adds geofencing auto-unlock, the eufy C220 adds Apple Watch unlock, and the ULTRALOQ U-Bolt adds a door sensor so the app knows whether the door is closed. Most locks run on 4 to 8 AA batteries; the Aqara U100 has a USB-C emergency port, which is a real backup when the cells finally die.

Auto-lock timing runs 10 to 99 seconds on the TEEHO pair, with a one-touch lock on the keypad. Voice unlock through Alexa or Google works on most WiFi locks, but reviewers note that geofencing auto-unlock can fire too early or too late in some setups. For homeowners who treat their front door like a GPS trolling motor with spot lock, the lock should hold position reliably without you babysitting the app.

Battery life and what happens when power fails

Long battery life is the difference between swapping AA cells twice a year and forgetting they exist. The TEEHO TE001 and TE002 claim up to 365 days, the eufy C220 hits 8 months on 8 AA, the Aqara U100 runs about 8 months with a USB-C emergency port, and the Schlage Encode sits at roughly 6 months. The Kwikset Halo is the shortest at around 3 months by some owner reports. Every lock on this list also ships with a physical backup key, and the Aqara U100 adds a USB-C emergency charge port for iPhone-only households.

How to Shop Smart Lock Deals During the Sale

Smart lock listings during Amazon’s October sale often mix the current generation with older models and bundle SKUs. Check the model number against the product page, confirm the finish and the included gateway (TEEHO and Sifely sell a separate WiFi gateway for remote features), and watch for renewed or open-box listings. Most offers during the sale need a Prime membership, and prices change through the event, so the listing on day one may not be the same as day two. Compare with a price history tool before you commit, and pick the lock that fits your door and your ecosystem first; the price is the bonus, not the reason.

Quick checklist for smart lock shopping during the sale:

• Confirm the lock fits your door thickness, backset, and handing.
• Decide whether you need built-in WiFi or are fine with a separate gateway.
• Match the lock to your smart home ecosystem: Apple Home, Alexa, Google, SmartThings, or Matter.
• Pick the keypad, fingerprint, or both, based on who actually unlocks the door.
• Check battery life and the backup plan: physical key, USB-C, or both.
• Compare the listing with a price history tool before you buy during the event.
