Part of our complete guide: best cash flow businesses.
- The best smart locks for Airbnb arbitrage issue codes that work only during the stay, keep an access log, auto-lock, and fit the existing door prep so you can restore the landlord's hardware.
- For 1-3 units, a hub-free WiFi keypad deadbolt such as the Philips 4200-series with lever (about $110 at the time of writing) covers it; codes are created in the app.
- Airbnb's native smart lock integration (US and Canada) supports Schlage, Yale and August locks and generates guest codes automatically.
- Multi-platform operators with 5+ units usually connect locks through a property management system instead.
- Give the property manager a permanent code and store the original lock; building fob access has to be solved separately.
The best smart locks for Airbnb arbitrage do four things without you standing at the door: issue a code that only works during the guest’s stay, log every entry, lock themselves behind a forgetful guest, and come off cleanly when your lease ends. For most single-unit operators that means a WiFi keypad deadbolt with no hub, like the Philips 4200-series with lever at roughly $110, and for anyone scaling past a few units, a lock that plugs into Airbnb or your management software so codes generate themselves.
Arbitrage adds one constraint that owner-hosts don’t have: the door is not yours. The landlord keeps a right of entry, the building may already have a fob system, and your lease almost certainly says you return the unit in the condition you received it. So the right lock is not just the smartest one. It is the one that fits a rented door, satisfies the owner, and saves you the most hours per check-in.
What actually matters on a rented door
Ignore the feature lists for a moment. Five questions decide it:
- Can you make time-limited codes? A code that turns on at 3 p.m. check-in and dies at 11 a.m. checkout is the whole point. One-time codes cover the cleaner and the plumber.
- Is there an access log? When a guest says they never got in, or a neighbor reports a party, the log is your record of who entered and when.
- Does it need a hub? Built-in WiFi means one less device to power and one less thing to fail. Most built-in WiFi locks use the 2.4 GHz band only, so check the unit’s router.
- Does it integrate with your booking tool? Manual code entry is fine at one unit. At five, it is an hour a week and a missed code eventually.
- Does it fit the existing door prep? Standard deadbolt holes mean no drilling, and no drilling means you can reinstall the landlord’s hardware and get your deposit back.
The five lock types arbitrage operators use
| Type | Remote code control | Booking auto-codes | Best fit |
|---|---|---|---|
| Standalone keypad deadbolt (no WiFi) | No, codes set at the door | No | Mid-term stays with one code per month |
| WiFi keypad deadbolt, no hub (e.g. Philips 4200) | Yes, via app | Manual in app; check current integrations | 1–3 units, owner-managed |
| Airbnb-integrated smart lock (Schlage, Yale, August) | Yes | Yes, through Airbnb’s native integration (US and Canada) | Airbnb-only operators with several units |
| PMS-integrated lock (via RemoteLock-type platforms) | Yes | Yes, across Airbnb, Vrbo and direct bookings | Multi-platform, 5+ units |
| Lockbox or smart key box | Some models | Rarely | Backup only, or when the lease forbids changing the lock |
Airbnb’s own smart lock integration, available to hosts in the US and Canada since 2024, works with Schlage, Yale and August locks: when a booking confirms, the lock gets a unique code that is active only for the stay, and Airbnb messages it to the guest. If you list on several platforms, a property management system connected to a lock platform does the same job across all of them.

Start building free →Our pick for one to three units: Philips 4200-series WiFi deadbolt with lever
For a new arbitrage operator with one unit and a phone, the Philips 4200-series WiFi keypad deadbolt with door lever hits the list above at a price that does not wreck the furnishing budget. What it does, per the manufacturer’s spec sheet:
- Built-in 2.4 GHz WiFi, no hub or bridge. It talks to the unit’s router directly.
- Code types that match hosting. Up to 100 user codes plus one-time codes, with recurring and temporary scheduled access, so a guest code can run from check-in to checkout and a cleaner code can work only on turnover days.
- A 24/7 activity log in the Philips Home Access app, with timestamps.
- Auto-lock after a delay you set between 10 and 180 seconds, which covers the guest who leaves for dinner with the door unlocked.
- Fingerprint, keypad, app and physical key entry, plus Alexa and Google Assistant voice control.
- A matching lever handle in the box, so the entry set looks like one piece instead of a smart deadbolt over an old knob.
- Standard door prep: fits doors roughly 1-3/8 to 2 inches thick with common cross-bore and backset sizes.
What to know before you buy: it runs on 8 AA batteries, so put a battery check on your monthly turnover list. It is WiFi-only on 2.4 GHz. And we could not confirm a native Airbnb or PMS integration at the time of writing, so plan on creating each guest’s code in the app when the booking lands. At one to three units that is a two-minute task. Past that, look at the integrated options. Pricing moves; it has been around $110 on Amazon, with a higher list price on the manufacturer’s site.
When a different lock makes more sense
You list only on Airbnb and plan to scale
Pick a lock on Airbnb’s integration list so codes generate automatically. Search current models and prices: Airbnb-compatible keypad smart locks. Confirm the specific model appears in Airbnb’s host settings before buying; compatibility is by brand and model, not by the word “smart.”
Your lease says you can’t change the lock
Some landlords will approve hosting but not new hardware. A code-based key lockbox mounted where the building allows is the fallback: key lockboxes. You lose the entry log and remote codes, so change the combination after every stay.
Owner’s closet, storage cage or gate
Every unit needs a locked closet for your spare linens, supplies and the landlord’s original hardware. A keyed padlock works, but a fingerprint-and-keypad model like the Anweller P15 smart padlock lets your cleaner in with a code you can change from your phone.
Keep the landlord on your side
The lock is part of your permission conversation, not an afterthought. What owners typically want:
- Access. Give the property manager a permanent code, or leave the original key cylinder operable if the model supports a physical key. Tell them in writing how to get in.
- A clean exit. Store the original deadbolt and knob in your owner’s closet and reinstall them at move-out.
- No drilling. Choose a lock that fits the existing bore. If the door needs modification, ask first.
- Building entry. If the front entrance runs on fobs, your unit lock solves only half the problem. Ask management how guests are supposed to get into the building, and get that answer before you list.
Our full walkthrough of the permission, rules and unit math is in how to start Airbnb arbitrage.
A five-minute door routine for every turnover
The lock only saves time if the codes stay clean. Build these into the cleaner’s checklist or your own:
- Confirm the outgoing guest’s code expired. Scheduled codes should die on their own; check the app once anyway, because a code left active is the most common smart-lock mistake.
- Read the log. Entries at odd hours or from codes you don’t recognize are worth a message before the next guest arrives.
- Check the battery level. Swap at the first low warning, not at the last one.
- Test auto-lock. Open the door, close it, and walk away. It should lock inside the delay you set.
- Rotate the cleaner code every month or whenever you change cleaners.
Name every code by guest and dates in the app. When something goes wrong, “Guest Jun 12–15” in the log is evidence; “Code 7” is a guess.
The same access logic runs a vending route
Here is the pattern worth noticing. A good lock system turns a job that needed you at the door into one that runs from your phone. That same shift is what makes a vending machine a workable side income next to a job: card readers and telemetry tell you what sold without a visit, and a decent lock keeps the cash box yours. If you are already in a managed complex with a friendly property manager, the lobby is a placement, and our apartment vending guide covers whether yours qualifies. Machine locks are their own category; see best vending machine locks for the T-handle and electronic options.

Frequently Asked Questions
What is the best smart lock for Airbnb if I only have one unit?
A WiFi keypad deadbolt that needs no hub is usually enough at one to three units. It lets you create a guest code that runs from check-in to checkout, a one-time code for a repair visit, and shows an entry log in the app. The Philips 4200-series with lever is one example at roughly $110 at the time of writing. You create codes by hand when bookings arrive, which takes a couple of minutes.
Which smart locks work directly with Airbnb?
Airbnb's native smart lock integration, rolled out to hosts in the US and Canada in 2024, supports Schlage, Yale and August locks. When a booking confirms, the lock gets a unique code active only for the stay and Airbnb sends it to the guest. Check the exact model in your Airbnb host settings before buying, because support is by model.
Can I install a smart lock in an apartment I rent for Airbnb arbitrage?
Only with the landlord's approval, which belongs in the same lease addendum that permits hosting. Choose a lock that fits the existing deadbolt holes, give the property manager a permanent code or key access, and keep the original hardware to reinstall when you move out. If the lease forbids changing locks, a code lockbox is the fallback.
Do WiFi smart locks work on 5 GHz networks?
Most locks with built-in WiFi, including the Philips 4200-series, connect on 2.4 GHz only. Most home routers broadcast both bands, so this is usually fine, but confirm the unit's router has 2.4 GHz enabled before installation day. A weak signal at the front door also drains batteries faster, so check signal strength there.
What happens if a smart lock battery dies during a guest stay?
Most smart locks warn in the app well before the batteries run out, and many keep a physical key override. The Philips 4200-series uses 8 AA batteries and supports a traditional key. Add a battery check to your turnover checklist and keep a spare key in a secured spot the cleaner or property manager can reach.
