I'm not as concerned with the 'law' or 'procedures' that are SUPPOSE to be done when I am given the key (keys) to something that involves true security or safety. If I have the final responsibility, I will normally change the tumblers (much easier and cheaper than the complete lockset) in the locks myself. Where ANYBODY else may have need of an 'emergency key', I will tape that key between two cheap (frays easily) pieces of cardboard (with my initials under the key), then put it in an envelope with my signed name and the date overlapping the glued flap. Give it to the party that 'has to have 'possible access' with a polite smile and "Sure, I understand. Just rip it open and use it whenever you have to and we can set up another one after whatever crisis."

Sometimes just the message that you are paying attention goes a long way in avoiding issues.
