I hate that i have to carry so many keys around, but at least I can carry them with something that will shout "I'm here!" Like many, I too have the same problem of losing my keys.
So at one time I had them ALL on one key ring. But one day I found that my car key wouldn't work in my ignition block. Long story short and a lot of money to fix, I ended up with a new car ignition block. Conclusion: Part of the problem was having too much weight hanging from the key as you drive. So I've made it easy to separate them. That way I'll only have the car key in the ignition. Lesson learned. But I will always keep the whistle nearby. ;)
