As technology advanced the number of car manufacturers began to combine physical and electronic protocols to avoid theft. Key systems like these also known as transponder keys or chips keys are designed to make it difficult for thieves to start an automobile.

The key chips inside the keys have a specific serial number that transmits a signal to the receiver inside of your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes are compatible, then your car will start.

The chip absorbs this energy and then transmits a radio frequency signal that contains an identification code. This code matches the unique digital serial numbers of the car's computers. This will prevent any an unauthorized attempt to start the car, as only the correct key will be able to perform the task.

The technology is believed to be more secure than the traditional car key, as it makes it harder for a criminal to "hot wire" the vehicle and then start it.
