Quick Answer: Use a smart lock, keypad or lockbox for the code, then add a QR code at the door that lets guests video-call you from their own phone if anything goes wrong. With DoorVi, a free QR video doorbell app, guests scan the code, you see them on video, and you can open a relay-connected door or gate from the call.
DoorVi (Recommended): keep your smart lock or lockbox for the code. Add a DoorVi QR code at the door so a guest who is stuck can video-call you in one scan, without your phone number. The app is free; support tickets are resolved within 24 hours.

Self check-in is one of the top 10 amenities guests filter for on Airbnb (Airbnb, Aug 2026), so hosts offer it. The weak spot is the moment the code doesn't work. That's where a QR code at the door helps.
Self check-in means guests can get into a place without the host being there (Airbnb Help Center). Airbnb lists three methods: a key lockbox, a smart lock and a keypad.
In the US and Canada, hosts can also connect one compatible Schlage, August or Yale smart lock per listing to Airbnb. Airbnb then creates a unique code for each trip that works only during the stay (Airbnb Help Center). Airbnb reported an average check-in rating of 4.96 for early smart lock stays (Airbnb Newsroom, Aug 21, 2024). Hosts in the UK and Australia can't use this direct integration today; Airbnb says a property management system (PMS) may offer one.
A QR code video doorbell is a printed code at the door that starts a video call to the host when a visitor scans it with their phone. DoorVi, a QR-code video intercom and visitor management platform, works this way: no wiring, no doorbell hardware, and the visitor doesn't need an app.
For a host, the QR code doesn't replace the lock. It covers the moment the lock, the code or the guest gets stuck.
Even good locks fail sometimes, and the guest is alone at the door when they do. Airbnb's own smart lock rules plan for it: when you connect a lock, you must add a backup entry method for dead batteries or a broken keypad, and Airbnb can share backup codes if the lock is offline (Airbnb Help Center).
Common failure points:
The guest scans, you answer on video, and the door opens or you talk them through it. Here is how each person experiences it.
The guest arrives and uses the code from their arrival guide. If it works, nothing changes. If it doesn't, they scan the QR code with their phone camera and a video call to you starts. No app download, and your phone number stays hidden by default.
Your phone rings like a normal call, even if you're in another city. You see the guest on video, so you know who is at the door. From there you can read them the backup code, point them to the right entrance or, if the door has a DoorVi relay, tap Open in the call.
You can link co-hosts or a cleaner to the same DoorVi address so the QR code reaches them too. The number of members depends on your plan: Silver up to 4, Gold up to 6, Platinum up to 20 (DoorVi FAQ).
If your rental is inside an apartment building or a gated community, the first barrier is often the shared entrance. With the property manager's approval, a DoorVi Wi-Fi relay (ESP32, Tasmota, Sonoff or Waveshare) can connect to an electric strike, magnetic lock or gate motor with a dry-contact or 12 V trigger, and the Open button appears in your app during the call (DoorVi FAQ). Larger buildings can use DoorVi with ProdataKey (PDK) or Brivo access control (DoorVi integrations). If there's a gated parking lot, the same relay approach can cover visitor parking entry.

DoorVi puts no camera at your listing, so the video comes only from the guest's phone when they choose to call. Airbnb banned indoor security cameras worldwide in March 2024. Doorbell cameras are still allowed, but outdoor cameras must be disclosed before booking (ABC7, Mar 12, 2024). Always check Airbnb's current policy and disclose any device you install, including a relay.
Install a smart lock, keypad or lockbox, then add the method and your instructions in your listing's arrival guide. Give each booking a unique code. Guests receive your instructions 24 to 48 hours before check-in.
