At its core, the Sentinel Key functions as a Hardware Lock. Developed by SafeNet (formerly Rainbow Technologies), these keys contain a unique, non-copyable serial number that the Autodata software queries before launching. When the software requests authorization, it scans the computer's USB ports for a valid response from the dongle. If the correct handshake fails, the software aborts startup and displays the infamous error. This system was effective for years under older Windows versions, which allowed low-level hardware access and unsigned kernel-mode drivers with relative ease.
Updates can interfere with the Sentinel HASP drivers.
