2. Door Handing Conversion (if necessary)

Your JOUNJIP Mechanical Deadbolt Lock is factory-set for "Right-Hinge" doors. If your door has hinges on the left when viewed from the outside, you must convert the lock's internal mechanism.

  • Locate the small plate on the back of the primary keypad body.
  • Carefully remove this plate.
  • Inside, you will find a small pin. Using a small screwdriver or pliers, move this pin to the right side for left-hinged doors.
  • Replace the plate securely.

2. Unlocking the Deadbolt

To unlock the deadbolt from the outside, you must enter the correct access code.

  • Always press the "C" button (clear button) before entering your passcode.
