You usually see these on fields that are co-owned or need to be accessed by several municipalities. Everybody gets their own key but can still have access to the area whenever needed.
Duplicating the key removes some accountability. With this set up you can revoke access to only one person, while leaving the access in place for everyone else. If you had a single lock with six copies then a bad actor getting a copy means you’d have to replace everyone else’s keys
This also means one person can’t take their lock off and replace it with another, and therefore lock out everyone else

Wouldn’t just duplicating the key achieve the same purpose or am I missing something?
