# What happens if the lockbox cannot connect to the internet?

## Offline Mode

Lubn AI Lockbox 3 can still operate in locations without network coverage. In offline mode, visitors can continue to use the QR code in their itinerary to release the keys; however, you will not receive real-time notifications from the lockbox.

If a visitor’s phone also does not have mobile signal, the Lubn mobile app will enter offline mode as well. If you know your lockbox is installed where mobile networks are not available, **advise visitors to sign in to the Lubn mobile app or open their web itinerary page** before traveling to the property and keep it available on their phones.

- By law (US), cellular towers should have a least 30 minutes of backup power in the event of a power outage. If the wide area power outage happens for long time, the device will be in the offline mode.
- For enhanced security, the QR code is dynamic and refreshes every few seconds, even when the device is offline. As a result, sharing a screenshot of the itinerary will not allow access. To grant visitor access, please [schedule the visit in the manager app](https://support.lubn.com/schedule-a-one-time-visit?hsLang=en) or invite the visitor to [self-schedule the visit](https://support.lubn.com/self-schedule-property-visits?hsLang=en) in your Self-schedule site.
