Danalock — calibrate the lock

1. Check the app and firmware. The new 4/5-point calibration requires 0.23.14 or later and the V3 app, not Classic.
2. Open Lock settings → Calibrate lock. Determine Hold Back Latch requirements from the lock case and follow the matching manufacturer video.
3. Follow the app endpoints. The manufacturer recommends an open door; lift the handle first if your door requires it.
4. Physically test locking and unlocking. For resistance or an incorrect endpoint, stop and contact the installer.
