Do smart locks integrate with Airbnb to generate guest codes automatically?

Not directly through Airbnb, but property management tools between your calendar and the lock can generate a code at check-in and expire it at checkout.

How many access codes does an Airbnb smart lock need?

More than you think. A listing running 60 to 100 stays a year plus cleaners and maintenance needs headroom — the Schlage Encode Plus supports up to 100.

What happens if the lock battery dies while a guest is outside?

It depends on the model. The Lockly Affirm has a USB-C emergency power port; most others rely on a mechanical key override. Set low-battery alerts and replace on a schedule.

The Best Smart Locks for Airbnb Hosts in 2026

The best smart lock for Airbnb is judged on one thing: can a guest let themselves in at 1am without you, a lockbox or a neighbour being involved? That means a keypad, a generous number of access codes that expire on schedule, and remote management from wherever you happen to be. This guide ranks seven locks on host-specific criteria and explains why two otherwise excellent smart locks are the wrong choice for a short-term rental.

How we ranked them

Four host requirements drove the ranking. A physical keypad is non-negotiable — app-only or phone-only entry fails the moment a guest arrives with a dead battery or no data roaming, which is exactly the scenario that generates a 1am phone call. Enough access codes matter: a busy listing cycles through dozens a year, and locks with a handful of code slots force manual housekeeping.

Remote management is essential, since you need to issue and revoke a code from another city. And battery life plus a fallback matter more here than in a home, because a dead lock on a turnover day is a cancelled booking. Weather rating and ANSI/BHMA grading round it out for exposed entrances. If the property is your own home, see the best smart lock overall; if you are a tenant, read the best smart lock for renters instead.

What each lock is best at

1. Schlage Encode Plus Smart Lock The host default. Up to 100 access codes is the number that actually matters — enough to run a busy listing without recycling codes between guests — and built-in Wi-Fi means you manage them remotely with no hub or bridge. Grade AAA ANSI/BHMA is the highest security rating available, with a built-in alarm, Matter certification and Apple Home Key. $249.99, four AA batteries lasting roughly 6 to 12 months. There is no fingerprint reader, which no host needs anyway.
2. Lockly Affirm Smart Deadbolt Built for exactly this use case: native Matter over Thread with no proprietary hub, IP65 weather rating for an exposed entrance, roughly eight months on eight AA batteries, and a USB-C emergency power port that has saved more than one turnover. The integrated doorbell button lets guests start a video call through Lockly's TapCom platform, removing a second device from the door. $179.99, with availability that slipped into Q2 2026.
3. Dreame Navo Smart Lock A10 The value pick at $179.99. Nine unlock methods including keypad codes and AI fingerprint, Matter over Thread, BHMA Grade 2 certification, IP65 weatherproofing and a rated 18-month battery — the longest here, which matters when the lock is at a property you visit occasionally. It is a first-generation product from a brand new to locks, so treat the long-term firmware support as unproven.
4. SwitchBot Lock Ultra Vision Pro The right answer for a self-managed property you also use yourself. The Keypad Vision Pro handles guest codes while facial recognition and palm vein scanning let you in without touching anything. Matter over Thread keeps response fast. $279.99 for the required combo, and facial recognition needs decent lighting — fine for an interior lobby, less reliable on a dark porch.
5. TCL D2 Pro Smart Lock Palm vein scanning plus a keypad at $169.99, and the 2026 revision works with any major ecosystem rather than locking you into one — useful if you manage properties across different platforms. Solid value, though TCL has a shorter track record in locks than Schlage or Yale, which is a real consideration for hardware you cannot easily service remotely.
6. August Wi-Fi Smart Lock (4th Gen) Ranked lower for hosts specifically, despite being an excellent lock. It retrofits over an existing deadbolt and issues guest codes through the app with a full activity feed — but there is no keypad, so entry depends on the guest installing an app and having connectivity. Fine for a long-stay rental where you can onboard guests in advance; risky for nightly turnovers. $229.99.
7. Level Lock+ Connect The wrong lock for Airbnb, listed so you do not buy it by mistake. It is beautiful — the entire mechanism hides in the door bore and the door looks untouched — but access is phone, key or Apple Home Key only, with no keypad at all. For a short-term rental that is a guaranteed support call. $329, and worth it for an owner-occupied home rather than a listing.

The verdict

For most hosts the Schlage Encode Plus is the correct purchase: 100 codes, built-in Wi-Fi, the highest security grade on the market and a brand with a service history. The Lockly Affirm is the better buy if the door is exposed to weather or you want the doorbell integrated, and the Dreame Navo A10 is the value choice at $180 if an 18-month battery and Matter over Thread appeal more than a long track record.

Whatever you choose, set codes to expire automatically at checkout rather than deleting them by hand — manual code management is how a former guest ends up with working access six months later. And keep a mechanical key override available to your cleaner, because every lock on this list eventually needs one. Pair the lock with one of the best smart home security systems if the property sits empty between stays.
