The Schlage Encode Smart WiFi Deadbolt leads our smart lock deals for Prime Big Deal Days because it pairs built-in WiFi with a fingerprint-resistant touchscreen and BHMA’s highest residential security rating, and over 13k owners have already rated it 4.2 stars. For a tighter budget, the TEEHO TE002 adds a one-second fingerprint reader and anti-peep codes without WiFi. Smart home tinkerers running Matter should keep an eye on the Ultraloq Bolt SE, which adds Matter-over-Thread to a built-in WiFi radio and seven ways in.
Prime Big Deal Days runs October 6-7, 2026, and most offers need a Prime membership.

We pulled specs, owner ratings and review counts from current Amazon listings and compared them side by side in October 2026. The list favors locks with high review counts, real owner feedback on reliability, and broad ecosystem support so you can actually use the lock with your phone, hub and voice assistant on day one. We did not run lab tests; everything here comes from listing data and what owners say in reviews.
Type: WiFi deadbolt
Unlock: Keypad, app, voice, key
Capacity: 100 codes
Cert: BHMA highest residential
Weight: 3.4 lb
The Schlage Encode is the easiest lock on this list to set up and forget about. Built-in WiFi means there is no bridge to buy and no extra app to install beyond the Schlage Home app, and over 13,000 owners give it 4.2 stars for that reason alone.
For most front doors, the Century trim in matte black looks closer to a traditional deadbolt than a gadget. Owners report a 15-minute swap with just a screwdriver, and the fingerprint-resistant touchscreen reads cleanly in the rain. You can hand out 100 codes, see who came and went, and trigger the built-in alarm if someone forces the door.
The Encode is the lock for anyone who wants one device that just works with Alexa and Google Home and does not want to think about a hub. Skip it if you need a fingerprint reader; go to the TEEHO TE002 or eufy C220 for that. Against the Ultraloq U-Bolt WiFi, the Encode trades proximity auto-unlock for a stronger BHMA rating and a longer track record with reviewers.
Type: Fingerprint keypad
Unlock: Fingerprint, code, PIN, key
Capacity: 20 fingerprints and 20 codes
Cert: BHMA Grade 3
Weather: IP54
If you want fingerprint entry without paying a premium, the TEEHO TE002 is the easy pick. The AI sensor learns as it goes, so the first few reads can be a touch slower, but reviewers say it settles into a one-second unlock fast. Anti-peep codes let you type extra digits before or after the real code so a shoulder surfer cannot memorize it.
Owners like the TEEHO because the install is a true 15-minute job with a single screwdriver, and the matte black finish holds up to weather. There is no app, no hub, no account to create. The trade-off is exactly that: you cannot unlock the door from your phone or hand out a one-time code remotely, so plan to set codes from the keypad itself.
Good to know: the TE002 stores 20 fingerprints and 20 codes, enough for a busy family plus a few regular visitors. Compared with the Veise KS02A, the TE002 has a similar fingerprint spec but adds one-time PINs that auto-delete, which is a nice touch for service calls. If you want WiFi on top, step up to the Ultraloq Bolt SE. For other value picks outside the lock category, our 12 Best Big Spring Sale Smart TV Deals on Amazon covers a related Prime-style event.
Type: WiFi and Matter
Unlock: 7-in-1 including fingerprint
Capacity: 50 fingerprints and 50 codes
Cert: ANSI BHMA
Weather: IP65
The Ultraloq Bolt SE is the only lock on this list with Matter over Thread plus built-in WiFi, so it plays nicely with Apple Home, Alexa, Google Home and any other Matter controller you already own. Seven unlock methods cover just about every way you might want to get in, from fingerprint to voice to two mechanical keys.
Owners report that once the Bolt SE is paired, it stays connected. The IP65 rating means it shrugs off rain and dust, and the 18-month battery life is one of the longer claims in this roundup. The app stores 50 fingerprints and 50 codes, which is generous for a household with regular visitors.
The Bolt SE trades Apple Home Key convenience for a fingerprint reader that does not need a Zigbee hub. Skip it if you are deep in the Apple Home world and tap-to-unlock is a must; the Aqara U100 is purpose-built for that. For Android-first homes running Matter, the Bolt SE is the one to watch during the sale.
Type: Keypad deadbolt
Unlock: Keypad, one-time PIN, key
Capacity: 20 codes
Cert: BHMA Grade 3
Weather: IP54
For a basic keypad swap, the TEEHO TE001 does the job without the extras. You get 20 individual codes plus one-time PINs for the dog walker, the satin nickel trim reads as a classic deadbolt from the curb, and 10,800+ owners have rated it 4.5 stars.
Setup is a single-screwdriver job, and the auto-lock timer keeps things sealed if you forget. Vacation mode locks out every code except the master, which is useful for longer trips. There is no app and no WiFi, so all programming happens at the keypad itself.
If fingerprint matters to you, step up to the Veise KS02A or TEEHO TE002 in the same price band; you keep the same BHMA Grade 3 and IP54 ratings but gain a one-touch sensor. For anything with WiFi and app control, jump to the Schlage Encode at the top of this list.
Type: Fingerprint keypad
Unlock: Fingerprint, code, one-time PIN, key
Capacity: 20 fingerprints and 20 codes
Cert: BHMA Grade 3
Weather: IP54
The Veise KS02A sits just above the TE001 in price but adds a fingerprint reader that wakes in 0.2 seconds at 99.99 percent accuracy, according to the listing. Owners confirm the sensor gets more reliable the more you use it, and the self-learning AI claims to pick up small skin changes over time.
Anti-peep codes work the same way as on the TEEHO models, letting you pad the real code with junk digits. The auto-lock window is adjustable from 10 to 99 seconds, so you can set it for the way your household actually moves. The 15-minute install fits a standard 2-1/8 inch door prep.
The KS02A trades a slower sensor for a slightly better-equipped one-time PIN system and a more compact body. Skip it if you want app control; go to the Veise RZ07 instead. For pure fingerprint value in a sale, this is the lock to watch.
Type: WiFi deadbolt
Unlock: 6 ways including fingerprint
Capacity: Multiple users
Cert: BHMA Grade 3
Weather: IP53
Day one of moving in is the moment the eufy Smart Lock C220 was built for. Built-in WiFi means no bridge to set up, the self-learning AI sensor reads faster the more you use it, and the C220 also pairs with Apple Watch, which is uncommon at this price. The eufy app walks you through every step, which matters if you have never installed a smart lock before.
Battery life is rated at 8 months on 8 AA cells, long enough that you will forget the batteries are even there. The IP53 rating is fine for a covered front door; a fully exposed door calls for a higher IP lock like the Ultraloq Bolt SE. eufy locks play best inside the eufy ecosystem, so plan to add a eufy doorbell or camera later if you want the full picture.
Anyone wanting a no-fuss fingerprint and WiFi combo without buying a hub should shortlist the C220. Skip the C220 if you live in a deep-Matter home; the Ultraloq Bolt SE is the broader pick. For pure simplicity and a lower price, the eufy C30 is the same brand without the fingerprint reader.
Type: Fingerprint with handles
Unlock: Fingerprint, code, temp code, key
Capacity: 20 fingerprints and 20 codes
Cert: BHMA/ANSI Grade 3
Weather: IP54
Most smart deadbolts assume you already have a working door handle. The Veise KS02B ships with two zinc alloy lever handles in the box, which makes it the right call for a new install on a door without an existing knob. The fingerprint reader wakes in 0.3 seconds at 99.99 percent accuracy.
Owners like the matte black finish and the way the levers feel in the hand. Silent mode turns off the keypad beeps for late-night entries, and vacation mode blocks every code except the master. The IP54 weather rating is the same as the rest of the Veise line, so it should hold up under an overhang.
Compared with the Veise KS02A, the KS02B adds the second handle and a slightly heavier 1.68 kg build. Skip it if you already have a handle you like; the KS02A is the cheaper path to the same fingerprint sensor. If your door has no handle at all, the KS02B is hard to beat on a sale.
Type: App-enabled deadbolt
Unlock: 7-in-1 including fingerprint
Capacity: 50 fingerprints and 250+ codes
Cert: BHMA and ANSI Grade 3
Weather: IP55
Short-term rental hosts, large families, and small offices care most about how many users a lock can hold. The Veise RZ07 stores 50 fingerprints and 250+ user codes, with eKey sharing for one-off access. The 0.2 second fingerprint sensor is the same as the KS02A, and the app shows a full log of who came and went.
The RZ07 runs on Bluetooth out of the box, and Veise sells a separate WiFi gateway if you want remote unlocks. Without the gateway you still get full keypad and fingerprint control, which is enough for many users. The IP55 weather rating is a small upgrade over the KS02A for slightly more exposed installs.
Anyone managing more than 10 people through one door will appreciate the code headroom. If you only need a handful of users, the TEEHO TE002 or Veise KS02A are the better value. For Apple Home Key convenience, the Aqara U100 is the right alternative, though it tops out at 50 fingerprints.
Type: Zigbee and Bluetooth
Unlock: Apple Home Key, fingerprint, code, app, key
Capacity: 50 fingerprints
Cert: AES encryption
Weather: IP65
The Aqara U100 is the only lock on this list that supports Apple Home Key, which means iPhone and Apple Watch owners can tap to unlock the way they would a hotel room. The fingerprint reader sits right above the keypad and stores up to 50 prints, and USB-C emergency charging saves the day if the batteries die.
Owners running an Aqara hub get remote access, one-time passwords, and a full activity log through the Aqara Home app. AES encryption is standard. The 8-month battery life on 8 AA cells is competitive, and the gyroscope-driven auto-lock kicks in the moment the door closes.
Compared with the Ultraloq Bolt SE, the U100 trades Matter for the Apple Home Key tap-to-unlock. Skip it if you do not live in the Apple ecosystem; the Bolt SE is the broader pick. If Home Key is on your must-have list, the U100 is the lock to watch during the sale.
Type: Bluetooth deadbolt
Unlock: 8-in-1 including fingerprint
Capacity: 50 fingerprints
Cert: BHMA Grade 3
Weather: IP54
Most smart locks on this list quote 5 to 12 months of battery life, but the DESLOC B200 pushes that to 12 months on a fresh set of cells. The lock ships with 8-in-1 entry, including fingerprint, PIN, app, eKey, key fobs, physical key and voice (with the optional G2 gateway). A USB-C port on the bottom handles emergencies if the batteries die.
Owners highlight the value at this price band, and the 50-fingerprint capacity is generous for the money. Without the gateway, the app is Bluetooth only, so remote unlocks need the add-on. The IP54 rating is fine for covered porches, and the BHMA Grade 3 certification matches most of the picks on this list.
The B200 trades the larger user code count of the Veise RZ07 for longer battery life. Want both long battery and remote access in one box? Add the G2 gateway during the sale. For a USB-C emergency port plus Apple Home Key, the Aqara U100 is the step up.
Type: WiFi deadbolt
Unlock: Passcode, app, auto unlock, voice, key
Capacity: 50 passcodes
Cert: ANSI/BHMA Grade 1
Weather: IP65
The Ultraloq U-Bolt WiFi comes with a door sensor in the box, so you can see whether the door is open, closed or ajar from the app. The auto-unlock feature uses your phone’s proximity to disengage the lock as you walk up, and auto-lock handles the back end. Built-in WiFi means no hub, which matters for renters who cannot install extra hardware.
The ANSI/BHMA Grade 1 rating is the highest residential security tier on this list, and the IP65 weather rating shrugs off rain. Owners can store 50 custom passcodes and the app generates time-limited eKeys for guests, which is useful for short-term rental hosts.
Compared with the Schlage Encode, the U-Bolt trades the Encode’s stronger track record for proximity auto-unlock and a door sensor. Skip it if your front door is fully exposed and you want the most reliable app; the Encode is the safer call. For renters who want the smartest deadbolt in the box, the U-Bolt WiFi is a strong sale pick.
Type: WiFi deadbolt
Unlock: Keypad, app, voice, key
Capacity: Multiple codes
Cert: BHMA Grade 3
Weather: IP53
For a connected deadbolt that does not need a separate fingerprint sensor or hub to feel smart, the eufy Smart Lock C30 is the straightforward pick. Keypad, app, voice, physical key, and built-in WiFi with no subscription. Owners praise the 15-minute install and the clean eufy app, and there is no monthly fee for remote access, which is rare in this price band.
The IP53 rating is best for a covered entry. The 5-month battery life is the shortest on this list, so budget for spare AAs. The C30 trades the fingerprint reader and the longer battery of the eufy C220 for a lower price. If you can stretch to the C220, the extra battery and fingerprint are worth it; if not, the C30 is a solid sale pick.
Good to know: eufy locks play best inside the eufy ecosystem, so plan to add an eufy doorbell or camera later if you want the full picture. The Ultraloq U-Bolt WiFi is the same no-subscription price band with auto-unlock and a door sensor instead.
Built-in WiFi locks like the Schlage Encode, Ultraloq Bolt SE, eufy C220 and Ultraloq U-Bolt WiFi work without a bridge, which keeps setup simple. Bluetooth-only locks like the DESLOC B200 and Veise RZ07 run fine without a hub but usually need an add-on gateway for remote access. Matter-over-Thread locks like the Ultraloq Bolt SE and Zigbee locks like the Aqara U100 need a compatible hub. If you already own an Aqara or Apple Home hub, the Aqara U100 is the cleanest fit; if you want the broadest future compatibility, the Bolt SE wins.
Fingerprint readers are the fastest way in for most families. The TEEHO TE002, Veise KS02A, eufy C220, DESLOC B200 and Veise RZ07 all read prints in under a second. If you carry an iPhone and want tap-to-unlock, the Aqara U100 is the only pick here with Apple Home Key. Keypad-only locks like the TEEHO TE001 are the cheapest option and still work great for households that prefer codes.
BHMA certification is the most important number to look for. The Ultraloq U-Bolt WiFi is the only Grade 1 lock on this list, the Schlage Encode carries the highest residential rating, and the rest are Grade 3. For an exposed front door, IP65 weather resistance (Ultraloq Bolt SE, Ultraloq U-Bolt WiFi, Aqara U100) is worth the small price premium over IP53 or IP54.
Most locks here store 20 to 50 fingerprints and 20 to 100 codes. The Veise RZ07 is the outlier with 250+ codes and eKey sharing, which is the right call for short-term rentals. For a regular family, 20 fingerprints and 20 codes is plenty. One-time PINs on the TEEHO and Veise models auto-delete after use, which is a nice touch for service calls.
Every lock on this list installs with a screwdriver in 15 to 30 minutes, and the listing videos cover the steps. Battery life ranges from 5 months on the eufy C30 to 18 months on the Ultraloq Bolt SE, and most run on AA cells. A USB-C emergency port (Aqara U100, DESLOC B200) is a quiet but useful backup if the batteries die at the wrong moment.
During Prime Big Deal Days, prices on smart locks tend to move throughout the two-day event, and the same model often sees multiple price drops.

Prime Big Deal Days runs October 6-7, 2026, and most offers are only available to Prime members. A free trial counts, and deal prices can change through the two-day event.
Smart lock prices during Prime Big Deal Days usually beat their everyday price, especially on mid-range fingerprint and WiFi models. Worth watching if you already planned a lock upgrade.
The Schlage Encode and the Ultraloq U-Bolt WiFi stand out for reliability, with the Encode holding the highest residential BHMA rating and the U-Bolt WiFi carrying a Grade 1 certification. Both have thousands of owner reviews backing the claims.
The Aqara Smart Lock U100 is the only lock on this list with native Apple Home Key support, so an iPhone or Apple Watch can tap to unlock. The Ultraloq Bolt SE works with Apple Home through Matter, but it does not support the tap-to-unlock Home Key flow.
The TEEHO TE001 is the cheapest on this list with a keypad, 20 codes and BHMA Grade 3. The TEEHO TE002 and Veise KS02A add fingerprint for a small step up in price.
Built-in WiFi locks like the Schlage Encode, Ultraloq U-Bolt WiFi, and eufy C220 work without any extra hub. Matter-over-Thread and Zigbee locks like the Ultraloq Bolt SE and Aqara U100 need a compatible hub for full features.
Buy the Schlage Encode if you want a reliable, no-hub WiFi deadbolt with the highest residential security rating and a long track record of happy owners. Buy the TEEHO TE002 if you want fingerprint on a tight budget. Pick the Ultraloq Bolt SE if your home runs on Matter or Thread. Choose the Aqara U100 for Apple Home Key tap-to-unlock. Run a busy rental with lots of users and the Veise RZ07 is the right call. Whichever lock fits, the button on each card goes to the current price during Prime Big Deal Days on October 6-7, 2026.
