The RFID signal transmitted between the key fob and the car is unique, encoded and tied to the vehicle's computer. This makes it nearly impossible for tech-savvy criminals to wire a stolen vehicle equipped with a key fob. These fobs can also be programmed to send a new frequency signal every time they're used.
