OMG flu…I laughed when I was reading your response.
To the OP, i’m sorry to hear about you losing your keys but at first while reading your post I thought it was a joke.
You drove for 25 minutes all that way and you really expected to find the keys not knowing where they fell off??
I seriously doubt someone took them off your car. I’d chalk it up to them falling off somewhere along the 25 minutes that you were driving. It’s impossible to say where they fell off and I personally wouldn’t worry unless you had some kind of identification or address on the keychain (which would be fairly foolish to have on).
Hard to believe someone would call the police or put up flyers over missing keys. Unless you had some key to some safe deposit box that had some serious loot in it. And even then, banks can easily get you a new key.
Inquiring minds want to know after reading your post (and Flu’s response…). What exactly was on your key chain?
If you’re that nervous about it, just change your lock for whatever keys you had on it but personally I wouldn’t do that unless you had your name/address on it.
