Kwikset Disable User

I have alot of users loaded in a kwikset 891 lock. Is there a way to disable most with out deleting them.

The only way I can think of is either changing their code or applying a time restriction that you know they will not be able to access the lock like 2 or 3 in the morning for 1 minute for one day. What are the odds huh?
If you want to keep their name and PIN for later reference, use the time restriction.
