Assuming you can get in (with a spare key) (same problem with a 5 leaver)
you tell the system to forget that key and start using a new one

unfortunately a vandal can damage the system in seconds, A ibutton reader
can be constructed out of 2 6" nails ! infact the commercial units are
so
discrete they can be mistaken for a door bell.

Also the benefit of a physical key is that it can be given to someone like
a
guest key, which you can activate just for the weekend, perhaps one for the
cleaner that just works on Monday mornings
