With this option you can mass update keys and change the maximum Key / ID usage value.
Enter the new value for the maximum ID / Key usage.
In the list select all keys you want to change and click on the button Update Max Key / ID Usage
For example
In the screen shot above you selected two keys with maximum key / ID usage equal to 2 and 1 respectively .
You entered 5 in the text box for the new value of the maximum key / ID usage.
On click of Update Max II Usage button the maximum key / ID usage of the selected keys will change to 5.
Note : The min value you can assign to the max key id usage must be equal or greater than the effective key ID usage value of the selected key.
For example
Example 1 - If for a selected key maximum key / ID usage is 3 and effective key ID usage is 2.
You type 1 for the new maximum key / ID usage value, then it will change maximum key / ID usage to 2 instead of 1 because 2 are already in use(effective id usage)
Example 2 - maximum key / ID usage - 5 Effective Key ID Usage - 5
New Value to be updated for maximum key / ID usage - 3
Then the update won't change the value of maximum key / ID usage as 5 are already in use suggested by Effective Key ID usage and will remain 5 only.
Solution For The Scenario - If you want to change the maximum key / ID usage in this case to 3, then first you need to deactivate the two licenses using License Usage screen. Then it will allow you to decrease the maximum key / ID usage to 3.
