the cancellation, in order to invalidate all previous keycards with
the same address.
IMPORTANT:
To cancel an Authorization keycard, encode a new Authorization
keycard with the same Authorization number, and then swipe it in
every FDU at the property, including the FDU used to encode the
new Authorization keycard. (See example 3.)
Example 1: New Guest Keycard
Imagine that a guest checks out, and the room is rented to a new guest. The previous
guest's keycard was created at the beginning of their registration (Time A). The current
guest's keycard is created at a later time (Time B). The following figure illustrates how
the new guest's keycard invalidates all previous Guest level keycards when it is first used
in the lock.

Cancellation of previous Guest keycards
Example 2: Grand Master Reset Keycard
The Grand Master keycard is always a duplicate (see
Section 4.5 – New Versus Duplicate
Keycards
and
Section 4.10, part A.16 – Grand Master
), so that more Grand Master
keycards can be made at any time without invalidating all the previous Grand Master
keycards.
To cancel all the circulating Grand Master keycards, a Grand Master Reset keycard is
made, and inserted in every lock on the property before it expires. In the following figure,
a Grand Master Reset encoded at Time B changes the valid time for all future Grand
Master keycards from A to B. Any Grand Master keycard made after Time B will be
accepted but those made at time A will now be refused.
