This feature is still vulnerable to a technique dubbed replay attack that allows thieves to record the signal of the key fob on the vehicle and reproduce it later to unlock the car.

The car is also programmed to shut down when it detects an incorrect frequency. This makes it much more difficult for car thieves with no experience to connect a vehicle with hot wires and then start it.
The chip and the key are linked by a circuit board that includes an induction coil. When the key is placed in the ignition it creates a magnetic field created around the transponder. This creates a signal which is taken up by the coil and then transmitted to the key identification number. The key’s ID number is sent back to the vehicle, and if it is in line with the engine will start.
