Some newer cars use a rolling key system, which keeps thieves from using stolen cars' key to open it. This feature is still susceptible to a technique called a replay attack.

The chip is a microcircuit which emits a radio frequency signal when the key is placed into the ignition. The car then recognizes the signal and then starts the engine if it matches the original frequency that was programmed into the vehicle. The car is also programmed to shut down if it detects an invalid frequency. This makes it more difficult for thieves who are not experienced to wire a vehicle and start it. The chip and the key are connected via an electronic circuit board that contains an induction coil. When the key is put in the ignition, a magnetic field is generated around the transponder. This produces a signal which gets taken up by the coil, which then transmits it to key's identification number. The key's identification number is then transmitted back to the car and the engine will start if the identification number matches.
