Key systems like these also known as transponder keys or chips keys are designed to make it difficult for thieves to start a vehicle.

This is to prevent any attempts by anyone else to start the car as only the proper keys will be able to do so.
This technology is thought to be more secure than a traditional car key since it makes it difficult for a criminal to "hot wire" the vehicle and then start it.
