Inside the cabinet, all keys are held in place using a key Tag attached to the keys which is used to identify the key when being returned. The cabinet will only release the key once it has been selected by the user at the terminal. The user will only be able to select from keys which they been assigned access to on the management software. Meanwhile all actions with the cabinet and terminal are logged on the software.

An electronic key management system requires all users to identify themselves at a control terminal to access the key cabinet. Users can identify themselves by using a PIN, fob, and card or even fingerprint biometrics; the terminal will then release the cabinet door if they are listed as authorised on the software.
