Maintaining detailed records of key usage is fundamental for effective key management procedures in data centre security. This practice involves documenting when and how keys are accessed and by whom, which creates an audit trail that can be critical for accountability, security, and compliance purposes.

By recording key usage, a data centre can promptly identify any unauthorized access attempts or security breaches. This allows management to respond quickly to potential threats and strengthens overall security measures. Additionally, having a comprehensive log of key distribution helps in the tracking of lost or misplaced keys, ensuring that no unauthorized individuals gain access to sensitive areas within the data centre.

In contrast, the other options would not contribute positively to key management. Using digital locks may enhance security but does not address the need for tracking and accountability. Allowing unrestricted access would compromise security, while providing keys to all staff members would increase the risk of unauthorized access. Thus, maintaining detailed records of key usage is the cornerstone of an effective key management strategy in a secure data centre environment.
