In the microcomputer five-prevention system, in order to prevent the five-prevention computer key from being damaged or malfunctioning, resulting in inability to unlock, emergency unlocking is required. Therefore, emergency unlocking keys are configured in the five-prevention system. However, in the actual use process, due to poor management of the emergency unlocking keys, the keys are misused, resulting in the microcomputer five-prevention system not being actually used. Therefore, it is necessary to reasonably manage the emergency unlocking keys.
