No one can get through the door using the reader.
Pinpoint user had right-clicked and inadvertently selected disable keypad/reader access when attempting to do a timed unlock.
This mode just shuts down the reader. The REX works and left-clicking on the Pinpoint animation allows unlock, and right-clicking stills allows timed and permanent unlock.
Right-click on the Pinpoint door animation and click on "Enable Keypad/Reader Access"
