I have had 6 FOB cars in the past 20 years. ALL require that the FOB RF signal be CLOSE to start and run. The Lexus and Lincoln required the KEY to be in the Ignition with the constant FOB RF sending the signal to START and RUN the car. My other FOB's that have NO KEY, require that the FOB be within a few feet of the Dash Push Button and you must push the Brake Pedal while pushing the Start Button. Just unlocking the Auto with a stolen or hacked RF signal will not get the Auto started. Doug
PS, I leave tinfoil draped over all the headrests and have never had a problem. Make sure you leave the Shiny side UP:B
exactly!!!! Once at a gas station/grocery store DW decided to start getting groceries while I gassed up. Well, I didn't realize I didn't have the keys with me, only the one in her purse. About 50 feet away car warnings came on saying key was out of range and car would shut down. I had to yell at her to come back so I could finish getting gas.
Most people don't realize that the Fob functions of LOCKING UNLOCKING ETC. are completely INDEPENDENT of the function of STARTING the car. remote functions rely on a rolling code RF function, STARTING the car relies on close proximity RF ID with rolling code.
The fact that both are rolling codes, pretty much eliminates someone from intercepting the fob transmission and then getting into the car, let alone starting it.
I would like to see actual verifieable data of the number of times ANYONE has been able to intercept the signal from a car remote, then unlock the car, let alone drive it away. (other than some demonstration using exotic equipment costing way more than the car to show it is possible)
But the "tin foil hats" folks can go ahead and support and make rich the amazon faraday shield sellers.
