I had to buy a big jingley chain and a clamp for my keys. I had a clapper that would beep when I clapped. Dam battery died. Keys are gone.

The super of the building made extra sets and I kept one in my shoe. Didn't work great because if I changed shoes I was screwed.

I am sort of OCD so I made a new ritual of clipping the keys on before I leave. That worked best. I wear a lanyard. Dumb.

It worked.
