Ademco RF Keyfob Programming question: how to 'unassign' user to RF kefob zone?

[Dave]

I scanned both the installation and operaton manuals for my Vista 20P, and I
can't figure out how to 'unassign' a user to an rf keyfob zone.

In some earlier posts, someone suggested that the 5804 could be used for
arming, while the keypad used for disarming. My 5804 is already programmed
for arm and disram.

I know I could delete the zone or change its function, but I'd like to keep
it easy to toggle the keyfob from full-function to arm-only, using the
assign to user functionality in the users manual.

Will assigning the zone to user #00 do it?
