Where was it?
i once left mine at the fuel station - I filled it up, went home and then noticed the following morning. I remembered having put it on the top of the pump. I went back feeling very foolish - but when I asked inside if anyone had found it the very disinterested chap behind the counter sighed, reached down and pulled out a huge cardboard box - full to the top with petrol caps. My idiocy was contextualised 😊 and after a few minutes trying the key in a number of them, I had mine back.
