• What happens if my KERONG lock battery runs out completely?

  If you forget your password, contact KERONG support or your locker administrator with your lock's SN number. They will provide a 10-digit OTP. Input this OTP followed by '#'. Once used, the OTP expires immediately, user passwords are cleared, and the manager password reverts to the default (0000).
