Good key retainer - Maxpedition Key Retention System Keyper 1703

This works well even attached to the webbing on my Colossus bag. No worries about losing the keys when I'm out and about. I think this is a good choice if you need to keep track of the keys to the ride home.
Pros: Easy Install, Bullet Proof function
