Key systems like these are also referred to as transponder keys or chips keys, are designed to make it difficult for thieves to steal the vehicle.

The code is matched to the unique serial numbers that are stored in the computer system of the car. This prevents unauthorised attempts to start the car as only the proper keys will be able to do so.

This technology is believed to be more secure than traditional car keys because it makes it much more difficult for thieves to "hot wire" the vehicle and start it.
