However, as time progressed and technology advanced as it did, automobile manufacturers began blending physical and electronic protocols to prevent theft. Key systems like these also known as transponder keys or chips keys are designed to make it more difficult for thieves to open the vehicle.

This helps prevent unauthorised attempts to start the car, as only the correct key will be able to start the car.
This technology is thought to be more secure than the traditional car key because it makes it harder for a thief "hot wire" the vehicle and then start it. automotive key programming 's not foolproof, and thieves have found ways of tricking and defeating the system.
