Just Read an article in CAr & Driver that said, thievs have a device that can obtain your car codes from 20 feet away. I wonder if this applies to the Prius. I know the car detects the Fob in your purse or pocket and all you have to do is touch the car handle to open it. Is there a code that goes from your car to the fob that can be copied? Also if copied can the same code be used to start the car? I know that the Fob must be in the car in order to start it. Do I need a wheellock bar to keep the car from being Boosted or stolen?
