Replacing the battery of a KleverKey Cylinder

Caution: Danger of injury caused by improper use

• Do not charge, open or heat the battery
• Always replace discharged batteries with new batteries
• Pay attention to the correct polarity when inserting the batteries
• Please use the following battery type: CR2 Panasonic Industrial Lithium
• Always replace the sealing ring (link) on cylinders used outdoors. Moisture penetration can lead to malfunctions

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.

• Enter the change battery service mode in the KleverKey portal:
  • Login to KleverKey Portal and go to Hardware -> Locks
  • Choose the KleverKey Cylinder for that you want to change the batteries
  • Select Enter service mode and press Change battery

• Press in the now unlocked sleeve-locking pin of the knob module with two paper clips or the
  Battery change tool and simultaneously pull out the sleeve

• Remove empty batteries and insert the new batteries, paying attention to the
  polarity

• 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.
