What occurs if a Knox master key is lost?

When a Knox master key is lost, it can pose a significant security risk, as it grants access to critical infrastructure and potentially sensitive areas. The procedure typically involves replacing all keys in the area to ensure that unauthorized access is not permitted. This is essential because the lost key could fall into the wrong hands, thus compromising the safety and security of various operations or properties.

Replacing all keys ensures that any old keys that might be in circulation are rendered useless, maintaining the integrity of access control systems. This action is widely recognized as a necessary safety measure to prevent potential misuse, which is why this response is consistent with best practices in emergency management and security protocols.
