A set of keys and a small flashlight attached to—what else?—a key fob

These are keys to

1. My locker at the office (where I keep my stuff and change of clothes for the week because I bike to work);
2. My lock for my bike (which is attached to a thick chain wrapped in clear plastic so it won’t nick or dent the frame);
3. The apartment (which also serves as my two bikes’ overnight parking garage);
