How do I upgrade firmware on a property device?

Property managers can upgrade firmware on the locks at their property using the DOOR App. This is the right path during walkthroughs, after a device is installed, or when DOOR releases a firmware update that's only relevant for property-team-managed common-area devices residents don't access. This article covers the manager-side flow.

About this feature

Firmware upgrades fix bugs and ship new features (e.g., shorter doorcodes need firmware G 2.0.7+ on G-Lens locks). DOOR distributes firmware via the DOOR App over Bluetooth, so:

The manager performing the upgrade must be physically near the device.
The device is unavailable during the upgrade — typically about 5 minutes per device while the firmware downloads, applies, and restarts. Plan upgrades for low-traffic windows on common-area doors.
Each device upgrades independently; you cannot bulk-upgrade an entire property in one tap.

Before you start

You're signed in to the DOOR App with a property-manager account that has Device Management Permissions for the property.
Your phone has Bluetooth enabled and the DOOR App has Bluetooth permission.
You're within Bluetooth range (~3 meters) of the device.
The device has enough battery for the upgrade. Upgrades fail or stall on critically low batteries — replace batteries first if needed.

Steps — See which devices need an upgrade

Sign in to DOOR OS.
Navigate to Reports → Access Devices.
Review the Firmware Version column and the Firmware Upgrade Needed indicator. Devices with a pending upgrade are flagged.
In the DOOR App, the Home screen shows a Locks section with three cards: Sync, Upgrade, and Low battery. Tap Upgrade to see the list of locks with a pending firmware upgrade.

Steps — Upgrade firmware on a single device

Open the DOOR App at the property.
Tap Devices in the bottom navigation.
Open the Doors tab and tap the device you want to upgrade.
Tap Upgrade Firmware (or your device's equivalent).
Stay within Bluetooth range (~3 meters) for the duration of the upgrade. The app shows progress; do not close the app or move away until the upgrade reports complete.
After the device restarts, perform a Door Sync and confirm the new firmware version in the device detail view.

Steps — If the upgrade fails

Confirm Bluetooth is on and reconnect to the device.
Check battery level on the device — replace if low.
Move closer to the device and retry the upgrade.
If the device still fails to upgrade, contact DOOR Support at support@door.com with the device's name, serial number, current firmware version, and the error message displayed in the app.

After the upgrade

Run a Door Sync from the device detail view to push any pending access updates the device may have missed during the firmware reboot.
For features that depend on a specific firmware version (e.g., shorter doorcodes need G 2.0.7+), confirm the new version meets the requirement before enabling those features in DOOR OS.
