My thoughts, too. What do you wanna bet it’s a restricted DND key. My entire career was filled with people wanting restricted keys, one of them was my Director at the county I worked for, & he had a key to his homeowner association’s pool, of course he wanted me to make it on the sly… I told him no & my manager went berserk. “You can’t tell him no!” Wanna bet? Of course, I was retiring in 3 weeks, so I didn’t care.
