    The key unlock was deleted in newer PLC software versions, but the lock logic remained.

    After a certain update by NEWAG, the cabin controls would also display scary messages about copyright violations if the HMI detected a subset of conditions that should've engaged the lock but the train was still operational.

    The trains also had a GSM telemetry unit that was broadcasting lock conditions, and in some cases appeared to be able to lock the train remotely.
