• Always replace discharged batteries with new batteries
• Pay attention to the correct polarity when inserting the
  batteries

Change the battery only with the door open. As long as the battery is removed, the cylinder cannot engage/disengage and thus cannot open/lock the door.

• Press locking pins and again slide on the knob module sleeve. Ensure that
  the locking pin latches correctly in the sleeve

• After the battery change, the knob module is still in the battery change
  position. By repeating the step 1, presenting an authorized smartcard or open the lock by the KleverKey app, the knob module returns to the home position.
