Why do none of the unlocking methods work from the inside?

If none of the unlocking methods (fingerprint, passcode, etc.) work from the inside panel of your DFF lock, this is typically due to the inside lock not being set up in the app. This is expected behavior for double-sided locks.

Cause

In a DFF double-sided lock:

• The inside and outside panels operate as separate locks
• Each panel must be added and configured individually in the app
• Unlocking methods assigned to the outside lock do not transfer to the inside lock

Result

If the inside panel has not been added to the app, it will not recognize any unlocking methods, even if they work on the outside.

Follow the steps below to properly configure the inside panel:

Step-by-step instructions

1. Open the TTLock app
2. Tap Add Lock
3. Select All Locks
4. Activate the inside lock’s Bluetooth by touching the fingerprint scanner
5. Wait for the lock’s serial number to appear in the app
6. Select the lock and proceed with adding it
7. Rename the lock (e.g., “Inside Lock”) to avoid confusion
8. Reassign all required unlocking methods (fingerprints, passcodes, etc.)

• The inside and outside locks are completely independent
• Each lock must be managed separately within the app
• Any updates or changes must be applied to both locks individually
