A Door Sync pushes the latest access updates and time settings from your phone to the Latch device over Bluetooth. Latch devices without an internet connection rely on these syncs from phones to receive any changes — after inviting a guest, revoking access, or changing a doorcode, a sync makes those changes take effect at the physical lock.
About this feature
Latch devices that are not connected to WiFi or Ethernet receive updates whenever a phone with the DOOR App comes within Bluetooth range and the app is open. This happens automatically on most unlocks. A manual Door Sync lets you force-push updates immediately without waiting for the next automatic sync.
Who can sync a door: Only someone who is signed in to the DOOR App and has active access to that specific door can perform a sync. If you are locked out of your account or your access has been removed, you cannot sync the door — a property manager or another resident with active access to that door must do it instead.
When to perform a Door Sync
- After inviting a guest who will use a doorcode before their first app unlock
- After revoking a guest's access
- After activating or deactivating a Latch Keycard
- After resetting a doorcode
- When you see an "Out of Schedule" error that shouldn't be happening (syncing resets the device's clock)
Before you start
- Be signed in to the DOOR App with active access to the door.
- Be within Bluetooth range — stand within ~3 meters of the Latch device.
- Keep the DOOR App in the foreground during the sync.
Steps
- Open the DOOR App and go to Access.
- Tap the door you want to sync.
- Tap the Sync option.
- Tap the Sync button.
- Stay within range of the lock and keep the app open until the sync completes — usually under 30 seconds.
- A confirmation message appears with the date and time of the last successful sync.
Note: The Sync page also shows the date and time of the previous sync before you start. This can help you tell whether the device has already received recent access changes.
If the sync fails
Sync fails or no confirmation appears: You may have moved too far from the lock, or Bluetooth dropped mid-sync. Move closer to the device, confirm Bluetooth is on, and try again.
You cannot access the DOOR App: If you are unable to sign in or your access was removed, you cannot perform the sync yourself. Contact your property management team — they can sync the door from their side or restore your access so you can sync it.
