What to do if the Xiaomi Self-Install Smart Lock is difficult to turn manually after installation?

If the Xiaomi Self-Install Smart Lock is difficult to turn manually after installation, please refer to the following information:
1. Please ensure that the knob accessories and bracket are installed correctly and not misaligned, which could increase friction.
2. After initial installation, manually rotate the knob to confirm it moves smoothly.
3. If the knob is still difficult to turn despite correct installation, use the one-touch lock/unlock button on the lock knob to operate it.
4. Check for any debris or dust inside the lock mechanism that can obstruct movement, and gently clean if necessary.
5. If the issue continues after performing the above steps, contact after-sales service for inspection or repair.
