All keys are trapped in the cabinet until authorisation is granted. A user is identified by a pin code. SmartKey+ highlights specific key positions that the operator is authorised to use. The user selects the appropriate key from the panel, and removes the key, as the selected key position is unlocked.
To reinsert a key in the SmartKey+ Cabinet, the user scans the key in front of the integrated scanner and the appropriate key position is highlighted on the frontal display for re-insertion.
