4.2.2 Replacing old Master cards with New Master cards
There are two ways to delete the lost Master card and register new Master card in
the lock.
(1) Using Maintenance Card
① Read the master cards (all Master cards to be used in a lock) to register
in each lock at Maintenance menu in LOS program
② Put the Maintenance card to the reader, and download the master card
chip numbers to the Card.
③ Put the Maintenance card to the locks, then, new Master cards will be
registered to the lock, and lost master card will be blocked.
(2) Using Owner Card
① Delete the old master card registrations in the lock (refer to the 4.1) with
Owner Card.
② Put new master cards to each lock so as to register new master cards.
Then, old master card you lost will not be used.
☞ All existing Master cards needs to be registered again together with new
Master card because all master card registrations were deleted if Owner card
is used.
