How does a LubnBox visit work?
Every visit takes four steps for the visitor, and you see each one as it happens. Each visitor gets their own dynamic QR code, so there is no shared door code to pass around.

Why teams choose Lubn
Remote
When a vendor, buyer or renter is stuck at the door, release the key from the dashboard or app.
Every check-in uploads a photo and an identity match.
Each person gets a role and a time-limited QR code, so there is no door code to pass around.
Managers are notified right away and can send staff to check. Optional GPS helps find the lockbox.
LTE needs no Wi-Fi or hub. The dynamic QR code still opens the lockbox with no signal.

Why an LTE lockbox instead of Bluetooth or PIN?
Bluetooth lockboxes reach about 10 meters and need a paired phone nearby. Lubn’s built-in LTE lets you unlock and check status from anywhere, with no Wi-Fi hub.
 Lubn AI Lockbox 3 |  BLE lockbox |  PIN or keypad lockbox | |
|---|---|---|---|
| Connectivity | LTE cellular. Provides real-time data anywhere with coverage. | Bluetooth. Requires a nearby smartphone and Bluetooth pairing. The visitor’s phone also needs cellular connectivity. | None. No real-time access data can be provided. |
| Remote access | Yes, from anywhere. Unlock remotely and monitor access via the cloud. | Only in proximity. Must be within about 10 meters. Some models connect to a Wi-Fi hub, which needs extra devices and setup. | No. |
| Offline access | Yes. Works in low or no signal areas through a proprietary dynamic QR algorithm. | No. Depends on phone signal for app sign-in, so visitors risk lockout without connectivity. | Yes, but no logging. |
| GPS tracking | Yes. Optional GPS module shows the device location on a map. | No. | No. |
| Data security | Strong. Encrypted cloud storage and communication. | Weak. Depends on app security; man-in-the-middle risk. | No. |
Lubn PMS: property management software for your portfolio
Lubn PMS is the web and mobile software that runs your lockboxes: schedule visits, verify visitors, set roles and review every entry across all your properties.
See every property and its lockbox on one map, with check-in status and upcoming visits.
Monitor battery, signal and key status for every lockbox in one list, and link each device to a property.
Set availability windows so visitors can book their own time, then track each visit from check-in to check-out, from one-hour home showings to weekly vendor visits.
Invite team members and give each a role: super admin, manager, or a custom role such as a contractor who can release a key. The Admin role is for Enterprise accounts.

Questions, answered first
Still have questions? Help center
Do I need Wi-Fi?
No. Lubn AI Lockbox 3 connects over LTE, so there’s no Wi-Fi or Bluetooth setup.
Can I release the key remotely?
Yes, on Premium and above. When a vendor, buyer or renter is stuck at the door, release the key from the dashboard or the app. Nobody has to drive to the site.
Does the lockbox work with no signal?
Yes. The dynamic QR code still opens the lockbox at sites with low or no signal, so visitors are not locked out. Remote release and check-in photos need coverage.
How long does the battery last?
The 10,100 mAh rechargeable battery lasts about 8 months on standby or 150 showings, and charges over USB-C. The app shows each lockbox’s battery level, and the device list shows which ones are running low.
Does Lubn have GPS tracking?
Yes, as an option. The GPS version ($299.95) shows the lockbox location on a map.
Can I give a vendor access for a set time?
Yes. Each visitor gets their own time-limited QR code by SMS or email, so there is no shared door code to pass around.
Do visitors need to install an app?
No. Visitors receive a time-limited QR code by SMS or email. The app is optional.
How much does it cost?
$269.95 for the LTE lockbox ($299.95 with GPS), plus a per-lockbox plan. Basic is free; Premium is $9.99 a month billed yearly ($12.95 monthly) and adds remote key release, check-in photo and realtime notifications.
How is Lubn different from SentriLock or Supra?
Many association-issued lockboxes work over Bluetooth or a keypad. Lubn adds LTE remote control and a photo check-in record, and its QR codes still work at sites with no signal. Subscriptions are flexible too, so you can scale your plan down for low seasons instead of paying for idle lockboxes all year.
Why a lockbox instead of card access?
Card readers need door hardware, power and network at every entry. A lockbox clamps onto existing doors and gates.
What’s the warranty?
One year, or up to three years with an active Enterprise subscription.
Can I return a lockbox?
Yes, within 14 days of delivery if it was bought from lubn.com and is unused and in its original condition. You are responsible for returning the device to Lubn. A $10 per unit restocking fee applies if the packaging is damaged, parts are missing or the device log shows more than ten check-ins or check-outs. If an item arrives damaged or defective, contact Lubn within 14 days for a replacement or full refund. Refunds can take about 10 business days to appear.
I have a V2 lockbox. Is there a trade-in?
Yes. Please refer to the V2 Trade-In Program.
