Some newer cars use a rolling key technology that keeps thieves from using a stolen car’s key to open it. The technology is still susceptible to a technique dubbed replay attack that allows thieves to record the signal received from the vehicle’s key fob and reproduce it later to open the car.

The chip is a microcircuit that transmits a radio frequency signal when the key is placed in the ignition.

This makes it harder for thieves with no experience to wire a vehicle hot and then start it.
