re: Anyone tried Key-Bar?

Really depends on how many keys you have, but I love mine. Massive pain getting the keys set and spaced if you're trying to do it after a couple beers, but once they're set you're good to go.

My truck has the fob built into the key (damn you Toyota) so for me it's great, takes up way less pocket space and I generally only use the pocket clip when I go running.
