My Challenger keys are not onmy active ring any more; they're in a leather key wallet my Grandma brought from Paraguay about 30 years ago. The live key ring has too many keys (work, home, two cars, lockers and cases, tool chest, etc), a Streamlight Nano flashlight and a braided paracord lanyard (about 10 feet). I used to keep a small pen-knife or sebre-tool too but it got to be too much of a PITA with travel at the airports.
