I've posted this on other threads, but may be missing something as to the way the your key rings are carried...I'm a retired science teacher, and had keys for the acid storage, flammables cabinet, and chemical supply storage on my key ring that needed a degree of security, so I never just laid down my keys on my desk..I used a double pull snap nylon belt loop with a plastic hook snap from a law enforcement supply shop to secure the keys to my belt...with a large central ring and several smaller rings to spread the bulk vertically not to increase the diameter.. they loop/snap arrangement was long enough that all the keys would fit in my rear pocket, and allow the pocket flap to be closed... this worked well, save for breaking the rather small link on the plastic Fox whistle, that I somehow lost...I use the same nylon double snap to secure my Maxpedition cell pouch, rather than a clip...these add a lot of security when out on the scooter (Yamaha FJR 1300)...
