Even though I went through this process about 10 years ago, I have found that I have more than a few keys for some lock, somewhere, that I cannot readily identify. Several of these are house front door type keys and some are odd shaped small or large keys. As I said, I went through this about 10 years ago and threw away a bunch of keys that I could not identify. Not once in these last 10 years I have discovered that I threw away a key that was needed or even possibly needed, but now I am again stymied in wondering what these keys are for. Two of them, I fear, were for a car top box that I sold in good faith to someone through Craigslist (I have no idea who it was since I insisted on cash when they came to pick it up) and hope I did not just fail to give them the keys to this item. Some of the others I am completely baffled as to what they are for. Maybe its just me and age, but now its driving me a bit batty trying to figure out what they are for before I toss them in the trash. Has this ever happened to you?
