I have nine keys. I'm not sure what they lock or unlock.
One of them is a double-sided type. That can only fit certain kinds of locks. The others are varying sizes, from smaller (padlock?) to larger (house keys?).
Four of them came from the keychain I've carried around in my pocket for the last eight years or so. It currently has only three keys on it - two car keys/fobs and my house key. My Golf Evolution keychain (for accessing our building, my padlock on my locker there, the old building at WWGC, etc.) is in my car. I believe I know what all of those keys are for.
What should my strategy be? I plan to go around my house and try a few locks I know I have, but after that, what? Should just permanently keep them in case they one day turn out to unlock something? They're just keys - it's not like they're a big burden. Maybe I could get a little Tupperware container for "Old Keys?"
