Bananas has been watching a youtube channel in which the ‘secure’ individual key has been diminished by as this authorised agent tries various keys to find he has one that opens doors and switches on the car. Most of these cars are american made but it does raise a question.
European cars seem more secure provided you cannot sniff the wireless protocol.
In England the Metropolitan police here London once ‘lost’ a set of universal car keys in the past and these where known to have entered criminal society.
I guess with enough patience and a vin a spare set of keys could be easily made.
Think about it.
