A key body 40 includes an open end 41 for receiving and surrounding surface features of a locking fixing. A key insert 44 is configured to move, relative to the open end 41 if a threshold force is exceeded, from an operational position where it is engageable with the surface feature to a non-operational position where it is not able to be engaged. The structure enables the key body to fail and be unusable if a non-compatible key insert is used with a particular configuration of locking fixing. The locking fixing also includes a guard wall surrounding its key surface features which prevents side access tampering.
