How to fix smart lock calibration problems

This is a key support article for smart-lock clusters because calibration often mixes software and mechanical causes.

1. Test deadbolt travel manually with the door open.
2. Correct strike-plate resistance and misalignment first.
3. Install fresh batteries if performance is inconsistent.
4. Repeat calibration only after smooth mechanical operation is confirmed.
5. Then verify app state, auto-lock and remote updates.
