So here's your classic 'If the key fits, it must be my car' case of mistaken identity, as a woman in Ohio inadvertently finds the key to her Camry fits someone else's similar-looking Camry. The article makes the event seem like a hit-by-meteorite bit of randomness, but in my personal experience you don't have to try many keys from the right era to unlock a pre-1990 Japanese car (try using an 80s Honda or Toyota key on random cars next time you're at the junkyard and you'll see what I mean). This is why kill switches for older Japanese cars should be considered a must-have.
