Definitely not carried with my keys. The thought of all that stuff banging around hanging from the ignition as I drive makes that a non-starter.
I have a spare key in the car that I use in the ignition.
Maybe better in your wallet? Ive HEARD but dont know for a fact if vehicle stolen with a hide a key kiss your insurance claim goodbye.
As I said I HEARD, I dont know if fact,just a thought....Any insurance peeps here?
