It has been report that the police and various insurance investigators are using data store on car keys as part of their ongoing investigation.
This may not be news to some of you but I’m willing to bet that majorities of the population were ignorant of how much information can be gleaned from a car key and manufacturer are not keen to advertise the fact. Smart explosion keys store details on a memory chip about the overall mileage of the car and how far it travelled on its last journey. Using a reader, dealers can extract this information and it can be used by the authorities or insurers to battle insurance fraud and, in some circumstances, accidents. Manufacturers have quietly and increasingly been using this technology and it has certainly been on some Renault and BMW vehicles for at least ten years!
