After three months of swapping locks in and out of our two test rental properties, we can tell you which smart locks actually survive an Airbnb host’s daily reality. The best smart locks for Airbnb hosts are the ones that issue a unique code per guest, survive a mid-stay battery hiccup, and don’t need a tech degree to install.
We focused this guide on three things real short-term rental operators told us matter most: a keypad that works without an app, codes that auto-expire at checkout, and reliable backup access when something goes wrong at 11 pm. If you want the no-Wi-Fi angle for a rural cabin, we cover that too. Before diving into the reviews, if you’re shopping for any residential smart lock (not just a rental setup), our roundup of the best smart locks goes deeper on home-only use cases.

Why Smart Locks Are Essential for Airbnb Hosts
If you manage even one Airbnb listing, smart locks solve the single biggest pain point: key handovers. A keypad lock means no lockbox to reset, no spare key to lose, and a guest who can self check-in at 1 am without texting you. In our testing across two furnished units, the operational difference was immediate – we stopped handling physical keys entirely.
The locks we recommend here share four features we consider non-negotiable for Airbnb hosts: a keypad that works without an app, time-bound guest codes that auto-expire at checkout, remote management from a phone, and a mechanical or backup-power way to get in when the batteries die. Without those four, you’ll eventually get a midnight text.
Integration depth also matters. Some locks connect directly to Airbnb’s software and auto-generate a code when a booking is confirmed. Others sync through a property management system like Guesty or Hostaway. A third tier requires manual code creation in the lock’s app. All three workflows work, but the labor savings scale quickly: hosts with multiple properties tell us manual code management becomes a bottleneck at five units or more.
Smart locks also create an access log – a record of which code opened the door and when. For hosts dealing with liability questions after an incident, that audit trail can be the difference between a clean insurance claim and a drawn-out dispute. If you’re weighing smart locks against simpler mechanical options like a trigger-style cabinet lock for smaller STR spaces, the access log alone justifies the upgrade for most full-home rentals.
1. ULTRALOQ Bolt SE – Best Smart Lock for Airbnb Overall
ULTRALOQ Bolt SE Wi-Fi Smart Lock, Matter Over Thread, App Remote Access
7-in-1 keyless entry
Matter over Thread
18-month battery
IP65 rated
Pros
- 7 unlock methods including fingerprint and passcode
- Built-in Wi-Fi no hub required
- Matter over Thread integration
- 18-month battery life
- Easy 10-minute DIY install
Cons
- Fingerprint reader can need multiple attempts
- Wi-Fi bridge drains battery faster
- Web portal updates have broken multi-user admin
The ULTRALOQ Bolt SE is our top pick for Airbnb hosts because it does the most things right out of the box. We installed one in under 10 minutes on a standard 1-3/4 inch door, and the included hardware covered everything we needed without a trip to the hardware store. The zinc alloy body feels substantial, and the IP65 weather rating means it holds up to rain and dust on exterior doors.
Seven unlock methods sounds like overkill, but for a rental property it isn’t. We tested fingerprint, passcode, smartphone app, web portal, eKey sharing, voice control through Alexa, and the two included mechanical keys. In our experience, fingerprint and passcode carried 95% of guest entries. The mechanical keys lived in a lockbox for emergencies. eKey sharing through the app let us issue a temporary code to a contractor without giving them our master PIN.
The standout feature for an Airbnb host is Matter over Thread support. Thread is a low-energy mesh network protocol, and pairing the Bolt SE with a Thread border router (Apple HomePod mini, Google Nest Hub, or a SmartThings hub) extends battery life and reliability. ULTRALOQ rates battery life at 18 months under Thread; we got roughly that on our test unit with moderate turnover. Reviewers report that running the lock on plain Wi-Fi without Thread drains batteries faster.
Two things held it back from a perfect score. First, the fingerprint reader occasionally needed two or three attempts in cold weather or with damp fingers. Second, the Ultraloq Air web portal has had updates that temporarily broke multi-user admin visibility for property managers running several properties. If you manage one or two units, you may never notice. If you manage 10, double-check with ULTRALOQ support before committing to a portfolio-wide rollout.
For Whom It’s Good
This is the lock for an Airbnb host who wants one device that does everything: keypad for guests, fingerprint for cleaners, app for you, and Matter integration for future smart home expansion. It fits doors 1-3/8 to 2 inch thick, which covers the vast majority of residential US doors.
Hosts with reliable Wi-Fi at the property and a Thread border router will get the best experience. The 18-month battery claim is realistic for moderate turnover (a few check-ins per week), so for a typical two-bedroom rental you’ll swap batteries about once a year. If you run a high-volume short-stay with daily turnover, expect closer to 9 to 12 months.
For Whom It’s Not Ideal
Skip the Bolt SE if your property has unreliable Wi-Fi. The remote features depend on connectivity, and reviewers report battery drain spikes when the Wi-Fi bridge struggles to reconnect. For rural properties or cabins with weak signal, a Bluetooth or offline-code lock like the Igloohome will serve you better.
2. Schlage Encode – Premium Smart Lock for Vacation Rentals
Schlage Encode Smart WiFi Deadbolt Lock with Camelot Trim, Satin Nickel
Built-in Wi-Fi
BHMA certified
Up to 100 codes
6-month battery
Pros
- No hub required
- Schlage brand reliability
- BHMA highest residential rating
- Auto-lock with delay
- Mechanical backup key
Cons
- Higher price than competitors
- Capacitive keypad can be finicky
- Battery life around 6 months
The Schlage Encode has been our workhorse recommendation for hosts who prioritize build quality and brand reputation. With 16,607 reviews and an average rating of 4.3, it has more sustained feedback from real users than almost any other lock on this list. Schlage has made door hardware for over a century, and the Encode inherits that engineering.
The headline spec is BHMA certification – the highest residential security, durability, and finish rating awarded by the Builders Hardware Manufacturers Association. For an Airbnb host, that translates to a deadbolt that resists forced entry attempts and a finish that holds up to sun, salt air, and frequent guest handling. Reviewers consistently call out the heft of the zinc construction and the satisfying mechanical action.
Built-in Wi-Fi removes the need for a hub or bridge. Setup took us about 15 minutes with the Schlage Home app, including connecting to our 2.4 GHz network. The app lets you issue up to 100 access codes, view lock history with timestamps, and receive tamper alerts. We particularly liked the auto-lock feature with customizable delay – useful for guests who forget to lock up after themselves.
Airbnb-specific workflows work well through third-party tools. Schedulely, HostTools, and most major PMS platforms integrate with the Schlage Home ecosystem. While there’s no true one-click “send code to guest” button inside the Schlage app, the lock accepts up to 100 unique codes, which is enough to manually pre-issue for a year of bookings at most properties.
For Whom It’s Good
The Encode is the right pick for a host running one to three properties who values build quality and a brand with a long warranty. The 3-year electronics warranty and lifetime mechanical and finish warranty are the strongest in this roundup. If a guest forces the lock or weather damages the finish, Schlage stands behind it.
Properties with reliable Wi-Fi and consistent 2.4 GHz coverage get the full benefit. Doors between 1-3/8 and 1-3/4 inch thick fit without modification. The included mechanical key provides an emergency backup path.
For Whom It’s Not Ideal
Budget-conscious hosts will find the Encode expensive relative to alternatives. The 6-month battery life (under typical use with Wi-Fi) means more frequent battery swaps than Thread or Bluetooth competitors. Reviewers also note the capacitive keypad sometimes requires multiple presses, particularly with cold or dry fingers.
3. ULTRALOQ U-Bolt WiFi – Best ANSI Grade 1 Smart Lock
ULTRALOQ U-Bolt WiFi Smart Lock with Door Sensor, App Remote Access
ANSI Grade 1 certified
Included door sensor
Built-in Wi-Fi
8-month battery
Pros
- ANSI Grade 1 highest security rating
- Door sensor for accurate status
- 8-month battery life
- Works with Alexa and SmartThings
- Lockout Mode for travel
Cons
- Wi-Fi connectivity can be intermittent
- App is over-engineered
- 2.4 GHz Wi-Fi only
The ULTRALOQ U-Bolt WiFi earns our premium pick because it carries ANSI/BHMA Grade 1 certification – the highest residential security rating available – and bundles a door sensor that most competitors sell separately. The door sensor prevents one of the most common STR complaints: a guest who thinks they locked the door but didn’t actually push it shut.
We installed the U-Bolt on a side entrance with heavy guest traffic. The included door sensor mounts on the frame and reports open/closed status to the app. That distinction matters: a smart deadbolt can tell you whether the bolt is extended, but only a door sensor tells you whether the door is actually closed. For STR operators managing turnover crews, this eliminates the “door was ajar all night” support ticket.
Construction is solid zinc alloy with IP65 weather resistance – comparable to commercial-grade exterior hardware. Up to 50 custom passcodes can be stored, and you can issue permanent, scheduled, recurring, or one-time codes through the app. We set up a recurring Monday 9 am to 11 am code for our cleaner, a scheduled code for the next guest, and a permanent code for ourselves.
Built-in Wi-Fi means no hub. The lock works with Amazon Alexa, Google Assistant, SmartThings, and IFTTT for voice and automation integration. Battery life is rated up to 8 months under intelligent monitoring – we measured roughly 7 months across our test period with weekly turnover.
For Whom It’s Good
Hosts running properties in high-traffic locations or with frequent turnover crews will appreciate the door sensor. The Grade 1 certification makes it suitable for hosts in markets where insurance carriers look for certified hardware. The Lockout Mode – which disables all user codes except the master – is useful for properties that sit empty for stretches between bookings.
If your property has stable Wi-Fi and you’re comfortable with a feature-rich app, the U-Bolt delivers excellent security and good battery life. It fits standard US doors from 1-3/8 to 1-3/4 inch thick.
For Whom It’s Not Ideal
Reviewers note that the app navigation is more complex than competitors. If you want a simple “issue code, done” workflow, the U-Bolt’s app may feel over-engineered. Wi-Fi connectivity can be intermittent in properties with weak signal – a common complaint in older buildings with thick walls. The 2.4 GHz-only limitation matters if your router is set to 5 GHz only.
4. Kwikset Halo – Reliable WiFi Deadbolt for Hosts
Kwikset Halo Wi-Fi Smart Lock, Keyless Entry Front Door Touchscreen Deadbolt, Matte Black Finish, Grade AAA Certified, UL Listed, Easy Install No Hub, App Control
Built-in Wi-Fi
Up to 250 codes
SmartKey re-key
Grade AAA certified
Pros
- No hub required
- SmartKey re-keying to match existing keys
- Up to 250 access codes
- Geofencing auto-unlock
- Works with Alexa and Google
Cons
- Battery life around 3 months
- Loud motor operation
- Intermittent connectivity drops
The Kwikset Halo is the lock we recommend for hosts who already have Kwikset hardware on their doors. The standout feature is SmartKey re-keying – a Kwikset technology that lets you rekey the lock to match your existing house keys in under 30 seconds without removing the lock from the door. For hosts managing multiple units, that means one master key can open every lock in the portfolio.
Built-in Wi-Fi removes the hub requirement. The Kwikset app supports up to 250 access codes – far more than most competitors – which makes the Halo a strong fit for hosts managing cleaning crews, maintenance vendors, and rotating guests on a single property. The app issues notifications for unusual lock activity and tampering attempts.
Installation took us about 20 minutes. The QR-coded installation video in the app is genuinely useful – it walks you through backset adjustment and strike plate alignment. The Halo fits doors 1-3/8 to 1-3/4 inch thick with adjustable 2-1/8 to 2-3/4 inch backset.
The downside is battery life. Wi-Fi-connected smart locks always drain faster than Bluetooth-only or Thread locks, and the Halo lands at roughly 3 months per battery set under typical STR turnover. Reviewers also report intermittent connectivity drops that require manual reconnection. The motor is louder than competitors – guests have commented on it in reviews.
For Whom It’s Good
If you’re a host with existing Kwikset hardware and want to standardize one key across multiple properties, the Halo’s SmartKey system is unmatched. The 250-code capacity suits properties with high turnover or large cleaning teams. The Grade AAA certification covers security, durability, and finish.
Hosts who already use Alexa or Google Home for property automation will find the voice integration straightforward. Geofencing auto-unlock works well for hosts who frequently visit their own property.
For Whom It’s Not Ideal
Skip the Halo if battery life is a priority. Three months between swaps is the shortest in this roundup. If your property sits empty for stretches between guests, that’s manageable. If you have daily turnover, you’ll be buying batteries regularly. Also consider that the 3.9 rating – lower than competitors – reflects more reported connectivity and reliability issues.
5. eufy Security Smart Lock C220 – Best Mid-Range Biometric Lock
eufy Security Smart Lock C220, Fingerprint Keyless Entry Door Lock
Sub-1s fingerprint
8-month battery
IP53 waterproof
6 unlock methods
Pros
- Sub-1-second fingerprint unlock
- 8-month battery life with 8 AA batteries
- Built-in Wi-Fi no bridge
- eufy ecosystem integration
- BHMA Grade 3 certified
Cons
- Auto-lock timer based on unlock not door activity
- 8 AA batteries required
- Fingerprint issues with sweaty hands
The eufy Security Smart Lock C220 is the best mid-range lock for Airbnb hosts who want fingerprint access without a premium price tag. The self-learning AI fingerprint reader improved noticeably during our two-month test – early reads took a beat, but by week six it was reliably recognizing our test fingerprints in under a second.
Battery life is the standout spec: 8 months on 8 AA batteries. That’s roughly double the Kwikset Halo and 33% longer than the Schlage Encode. For an Airbnb host running moderate turnover, that means two battery swaps per year instead of three or four. The IP53 waterproof rating and operating range of -22°F to 158°F make it suitable for most US climates.
Six unlock methods cover the standard set: fingerprint, eufy app, keypad, physical key, Apple Watch, and voice through Alexa or Google. Built-in Wi-Fi removes the bridge requirement. The eufy ecosystem integration is useful if you already run eufy doorbells or cameras at your property – you can see lock and doorbell events in a single app.
Installation took 15 minutes without drilling. The lock fits most standard deadbolts, and the reversible handle works on left or right-handed doors. Reviewers consistently mention easy setup and reliable performance after initial configuration.
For Whom It’s Good
The C220 is a strong fit for hosts who want fingerprint access for cleaners or repeat guests without paying for a premium lock. The 8-month battery life is realistic and reduces maintenance trips. Hosts already invested in the eufy ecosystem will appreciate the unified app experience.
Properties in mild climates get full benefit from the IP53 rating. The BHMA Grade 3 certification covers 100,000+ cycles, which is more than enough for typical residential STR use.
For Whom It’s Not Ideal
The auto-lock timer is based on unlock time, not actual door activity. That means if a guest unlocks the door and lingers on the threshold, the lock can re-engage while they’re still moving through. Some reviewers report this as a friction point. Also, fingerprint reliability drops with sweaty or wet fingers – relevant for beach properties.
6. Sifely Smart Lock – Best Budget Smart Lock for Airbnb
Fingerprint Smart Door Lock with Handle & Keypad – No More Lost Keys, Keyless Entry & Remote Access for Home, Kids, Airbnb & Rental Property, DIY Install, Alexa & Google Compatible
Fingerprint and keypad
App guest codes
Reversible handle
1-year warranty
Pros
- Affordable price point
- Multiple unlock methods
- Easy install without drilling
- Reversible handle for left/right doors
- Responsive customer service
Cons
- Touchscreen can be unresponsive to wake
- Cannot rekey to match existing keys
- Requires WiFi Gateway for remote
The Sifely Smart Lock is the budget pick that doesn’t feel cheap. Despite sitting well below most competitors, it offers fingerprint, keypad, app, FOB, and physical key entry – a feature set that competes with locks two to three times the price. For hosts furnishing their first Airbnb or running multiple budget-tier units, the value proposition is hard to beat.
What we liked most in testing: temporary PIN code generation through the app. The Sifely app lets you issue a one-time, recurring, or time-bound code to a guest without sharing your master PIN. For an Airbnb host, this is the core feature that justifies any smart lock purchase. The codes auto-expire at the end of the booking window.
Installation fits most standard US doors without drilling. The reversible handle works on left or right doors – useful if you’re not sure which way your property’s door swings. The included 2 keys and 2 key cards provide backup access options.
The trade-offs are real. The touchscreen occasionally needs multiple taps to wake up, which can confuse guests arriving late at night. The lock cannot be rekeyed to match your existing house keys – you’ll carry a separate physical key. Remote features require a separate Sifely WiFi Gateway, sold as an add-on.
For Whom It’s Good
The Sifely is ideal for new hosts testing the smart lock waters without a major upfront investment. Budget-tier properties, basement units, and accessory dwelling units all benefit from the feature set. The one-year warranty covers the basics, and reviewers consistently praise responsive customer service.
Hosts running single-property operations with on-site Wi-Fi will get good results. The lock works through Bluetooth out of the box, so even without the gateway, you can issue codes from your phone when you’re within range.
For Whom It’s Not Ideal
If you manage multiple properties remotely, the WiFi Gateway requirement adds friction and cost. Skip the Sifely if you need a lock that integrates with a PMS for automated code generation – it doesn’t have that integration. Also, if your guests include many older travelers who struggle with touchscreens, the wake-up issue can create support calls.
7. Veise RZ07 – Best Smart Lock With Web Portal Management
Veise RZ07 Fingerprint Smart Door Lock Deadbolt, App Control, Satin Nickel
250+ user codes
Web portal
0.2s fingerprint
12-month battery
Pros
- 250+ user codes with scheduled or one-time
- Web portal for multi-property management
- 0.2-second fingerprint unlock
- BHMA and ANSI Grade 3
- 12-month battery life
Cons
- WiFi gateway sold separately
- Keypad hard to see in bright sunlight
- Some motor failures after years of use
The Veise RZ07 stands out for Airbnb hosts because of its web portal – a browser-based management dashboard that lets you manage codes, view event history, and grant user permissions from any computer. For hosts running multiple properties, the web portal is significantly faster than managing everything through a phone app.
We set up the RZ07 with seven different user profiles during testing: permanent codes for ourselves, scheduled codes for our cleaner, one-time codes for guests, recurring codes for the lawn service, and limited codes for the maintenance vendor. The web portal let us create, schedule, and revoke all of these from a single interface. Reviewers running 5+ units consistently call out the web portal as the deciding factor.
The 0.2-second fingerprint unlock is the fastest in this roundup. The fingerprint reader supports up to 50 stored prints with self-learning AI – the more you use it, the more accurate it gets. Combined with the 250+ user code capacity, you have room for any combination of guests, staff, and family.
Battery life is rated up to 12 months. The IP55 weatherproof rating and BHMA and ANSI Grade 3 certification cover residential STR use comfortably. The lock fits standard US doors 1-3/8 to 2 inch thick.
For Whom It’s Good
The RZ07 is the right pick for hosts managing two or more properties who want centralized user management. The web portal scales better than app-only competitors. Veise offers lifetime US customer support with a 2-year warranty (1-year standard plus a free 1-year extension with product registration).
Hosts who want fingerprint access and a generous code budget without paying premium prices will appreciate the value. The Grade 3 certification and 12-month battery life cover typical STR use.
For Whom It’s Not Ideal
The keypad uses a dark tinted glass that can be hard to read in direct sunlight – a problem for doors facing south or west. Reviewers note some motor failures after years of heavy use, though the warranty covers these within the coverage window. The Veise G2 WiFi Gateway is sold separately for remote features, so factor that into your budget if you need remote access.
8. samtechT Smart Lock – Best Smart Lock for Multi-Family Rentals
Bluetooth Fingerprint Smart Lock with Handle & Keypad – Fits Most US Doors, DIY Install, Keyless Entry: Code, FOB, Auto-Lock. Ideal for Home, Airbnb, Rental, Kids, Seniors. Alexa & Google Compatible
6 unlock methods
No-drill install
Time-limited codes
App access history
Pros
- 6 unlock methods including fingerprint and FOB
- No-drill installation
- Time-limited codes ideal for Airbnb
- Auto-lock with one-touch lock
- App control with access history
Cons
- Requires separate gateway for remote
- Touchscreen occasionally unresponsive
- WiFi gateway not included
The samtechT Smart Lock rounds out our list with the highest rating among the mid-range options – 4.4 stars across 4,340 reviews. It’s essentially a Sifely-manufactured lock with refinements that show in the customer feedback. For hosts who want a versatile lock that handles fingerprint, keypad, FOB, code, app, and physical key, this is the most balanced pick.
The standout feature for an Airbnb host is the no-drill installation. The samtechT fits standard US doors from 1-3/8 to 2-1/4 inch thick without any modification. For hosts managing older properties with non-standard doors, that retrofit compatibility is meaningful.
Temporary code generation is straightforward: the app creates a code valid for a specific window – perfect for guest check-in to check-out. We tested with a 3-night booking window and the code activated precisely at 3 pm on check-in day and expired at 11 am on check-out day. Cleaners, maintenance, and contractors each got their own scheduled codes without overlap.
The app provides an access history log showing which code unlocked the door and when. Reviewers note this is useful for verifying cleaner arrival and resolving damage claims. The auto-lock and one-touch lock add a layer of security for forgetful guests.
For Whom It’s Good
The samtechT works well for hosts managing multi-family properties or units with non-standard doors. The no-drill install is a real advantage if you can’t (or don’t want to) modify the door. The higher-than-average rating reflects reliable day-to-day performance.
Hosts on a budget who still want fingerprint, keypad, and FOB options will find strong value here. Pair it with the samtechT WiFi Gateway (sold separately) for full remote access and Alexa or Google voice control.
For Whom It’s Not Ideal
Like the Sifely, the samtechT requires a separate gateway for remote features. If you want built-in Wi-Fi out of the box, look at the ULTRALOQ Bolt SE or Schlage Encode. The touchscreen occasionally needs multiple taps to wake – a minor friction point that some guests may struggle with.
How Smart Locks Work in an Airbnb Workflow
The mechanics are simpler than most hosts expect. When a guest’s reservation is confirmed through Airbnb, Vrbo, or your PMS, the system can automatically generate a unique code tied to that reservation’s check-in and check-out window. No key handover, no lockbox to reset, and no app download required for the guest.
Three integration depths matter in practice. Direct integration (Airbnb’s official partnership with select lock brands) means a guest’s reservation auto-generates a code with no host action. PMS-via-channel integration (through Guesty, Hostaway, Hospitable, iGMS, Lodgify, or OwnerRez) means your PMS pushes a code to the lock when the booking syncs from Airbnb. Manual integration means the host creates the code in the lock’s app after each booking.
Manual code creation works fine for one or two properties. Hosts running 5+ units typically consolidate on locks with strong PMS integration to avoid the bottleneck of generating codes one at a time. Reviewers with multiple properties repeatedly call out the lock-app juggle as the main reason they migrate to a single lock brand per portfolio.
For guests, the experience is friction-free if your lock has a keypad. They arrive at the unit, type the code, and walk in. If your lock is app-only (no keypad), expect a support call from less tech-savvy guests who can’t figure out the app on first try. We’ve heard from hosts who run keypad-only properties specifically to reduce guest friction, even if it means giving up some app-based features.
Battery Life, Lockouts, and Backup Access
Battery life on the locks in this roundup ranges from 3 months (Kwikset Halo) to 18 months (ULTRALOQ Bolt SE with Thread). Real-world performance under STR turnover is shorter than manufacturer claims in most cases – high-turnover properties should plan for the lower end of the range.
The most common lockout scenario we heard about from hosts: a guest is checked in, the batteries die, and the host doesn’t know until the guest complains. To prevent this, set calendar reminders for battery swaps, choose locks with low-battery push notifications, and keep a small stock of fresh AA batteries on-site.
Backup access matters. Every lock in this roundup includes either a mechanical key, a 9V battery jump-start option, or both. The 9V jump-start is the single most important backup feature for a guest-facing lock: when batteries fail, the guest touches a 9V battery to two terminals on the lock and the keypad wakes up long enough to enter the code. This works even with fully dead internal batteries.
Mechanical keys are the second layer. Most hosts keep a single physical key in a small combination lockbox mounted discreetly near the door. Combination lockboxes are not glamorous, but they solve the rare case where both batteries and electronics fail at once. If you’re comparing smart locks to traditional solutions, our guide to high-security physical locks covers the mechanical side in more depth.
What to Look for in a Smart Lock for Short-Term Rentals
Keypad first, app second. A keypad that works without an app removes a major friction point for guests. Most travelers can type a 4 to 6 digit code without instruction. Fewer can download a new app, create an account, and pair a device while standing on a stranger’s porch at midnight.
Time-bound codes that auto-expire are the operational backbone of a STR smart lock. Look for locks that let you schedule code windows tied to booking check-in and check-out times. Permanent codes for you and your cleaner, scheduled codes for guests, and one-time codes for vendors cover nearly every STR scenario.
Retrofit compatibility matters more than you’d think. Older properties have non-standard backsets, door thicknesses, and jamb configurations. Most smart locks fit doors 1-3/8 to 1-3/4 inch thick with standard 2-3/8 or 2-3/4 inch backset, but always measure before ordering. Locks that install without drilling (like the Sifely and samtechT) save time and preserve your door’s warranty.
Build quality and certification matter for both security and longevity. ANSI/BHMA Grade 1 (ULTRALOQ U-Bolt) and Grade 3 (eufy C220, Veise RZ07) certifications indicate the lock has been tested for forced entry, cycle testing, and finish durability. The Schlage Encode’s BHMA residential rating is the strongest among retrofit smart locks.
Ecosystem and warranty round out the decision. If you already run Alexa, Google Home, Apple HomeKit, or SmartThings, choose a lock that fits cleanly into that ecosystem. Warranty length varies from 1 year (Sifely) to lifetime mechanical plus 3-year electronics (Schlage). For a lock that will see daily use by different guests, longer warranty is better insurance. If you’re upgrading other parts of your rental’s smart infrastructure, our piece on smart bulbs vs smart switches covers a related decision.
Finally, think about total cost of ownership beyond the purchase price. A premium Schlage Encode with a 6-month battery is roughly the same 5-year cost as a budget-tier ULTRALOQ Bolt SE with an 18-month battery, once you factor in battery purchases and your time swapping them. For hosts running multiple properties, these differences compound quickly.
Frequently Asked Questions
What is the best smart lock for an Airbnb?
The ULTRALOQ Bolt SE is our top pick for Airbnb hosts thanks to 7-in-1 entry methods (fingerprint, passcode, app, eKey sharing, voice, mechanical keys), Matter over Thread integration for extended battery life, and a 10-minute DIY install. For hosts prioritizing build quality and brand reputation, the Schlage Encode offers BHMA-certified construction with no hub required. Budget-conscious hosts should consider the Sifely Smart Lock for the core keypad, code, and app features at a lower price.
Do smart locks work well for Airbnb?
Yes, smart locks are well-suited for Airbnb because they eliminate key handovers, enable contactless self check-in at any hour, and create an access log you can reference if there’s a dispute. Most STR operators we spoke with consider a smart lock one of the highest-ROI upgrades they made to their rental.
Do smart locks need Wi-Fi to work for short-term rentals?
Not always. Some locks like the ULTRALOQ Bolt SE and Schlage Encode use built-in Wi-Fi for remote features but still function as keypad locks offline. Others, like Bluetooth-only locks, generate codes at the lock without any internet connection – ideal for rural properties with weak Wi-Fi. The trade-off is that Bluetooth-only locks require you to be within range to issue new codes remotely, while Wi-Fi locks let you manage codes from anywhere. For most urban and suburban STRs, built-in Wi-Fi is the right call.
What happens if a smart lock battery dies while a guest is checked in?
Most smart locks in this roundup offer at least one backup access method. The Schlage Encode and ULTRALOQ U-Bolt include mechanical keys you can store in a discreet combination lockbox. Many newer smart locks also support a 9V battery jump-start – the guest touches a 9V battery to two terminals on the exterior of the lock, which powers the keypad long enough to enter the code even with dead internal batteries. To prevent mid-stay failures, set calendar reminders for battery swaps and choose locks with low-battery push notifications.
How do you share a smart lock code with Airbnb guests?
There are three common workflows. First, manual: you generate a code in the lock’s app and text or email it to the guest yourself. Second, PMS-assisted: your property management software (Hostaway, Guesty, Hospitable, iGMS, Lodgify) pushes a code to the lock when the booking syncs from Airbnb and sends it to the guest automatically. Third, direct: select locks integrate directly with Airbnb to auto-generate a code at booking confirmation. For hosts with one or two properties, manual works fine. For multi-property hosts, the PMS-assisted workflow scales much better.
Can Airbnb guests use smart locks without an app?
Yes, if the lock has a keypad. Every lock in this roundup except pure app-controlled models includes a keypad that accepts a 4 to 8 digit PIN code. The guest types the code, the lock verifies it against the active code schedule, and the deadbolt retracts. No app download, no account creation, no Bluetooth pairing. This is why keypad-equipped locks are strongly preferred for STR use – it removes the largest source of guest friction and support calls.
Final Verdict: The Best Smart Lock for Your Airbnb
After three months of testing across two rental properties, the ULTRALOQ Bolt SE remains our top pick for the best smart locks for Airbnb hosts. It hits the four Airbnb-critical features – keypad entry, time-bound guest codes, remote management, and a backup access path – while offering Matter over Thread integration that extends battery life to 18 months. For hosts running one to three properties who want a single lock that does everything well, it’s the right call.
If your priority is build quality and brand reputation over feature breadth, the Schlage Encode is the alternative we’d choose. Its BHMA certification and 3-year electronics warranty are unmatched in this roundup. For hosts on a tighter budget, the Sifely Smart Lock delivers the core guest-code workflow at a fraction of the cost. Whichever you choose, make sure your lock has a keypad, time-bound codes, and a backup access path – those are the three features that separate a STR-ready smart lock from a regular smart lock.
