Certain vehicles of recent years use rolling keys to keep thieves from using stolen keys to open the vehicle. The technology is still susceptible to a technique dubbed a replay attack which allows thieves to record the signal received from the key fob on the vehicle and then replicate it to open the car.

Transponder chips

Transponder chips, which are used to protect cars from theft, are a common feature of modern cars. The chip is a microcircuit that emits a radio frequency signal when the ignition key is put in. The car is able to detect the signal, and starts the engine only if the signal matches the one programmed into the vehicle. The vehicle is also programmed to stop when it detects an incorrect frequency. This makes it harder for thieves with no experience to wire a vehicle hot and then turn it on.

A circuit board that has an induction coil connects the key to the chip. When the key is inserted into the ignition, it creates a magnetic field around the transponder. This produces a signal which is amplified by the coil which sends it to the key's identification number. The key's ID number is transmitted back to the vehicle, and if it is in line with the engine will start.
