As technology advanced, more and more automobile makers began to mix physical and electronic protocols to avoid theft. Key systems, also known as transponder keys or chips keys are designed to make it more difficult for thieves to steal a vehicle. The key chips come with unique serial codes which transmits a signal to the receiver in your car. When the signal is received it is compared to an existing code in the car's computer. If the codes match, your car will start. If the codes don't match, your vehicle won't start at all.

The chip absorbs this energy, and then transmits a radiofrequency signal that contains an identification code. This code is in line with the unique serial numbers of the car's computers. This is to prevent any attempts by anyone else to start the car, as only proper keys will be able to do so. This type of technology is thought to be more secure than a traditional car key because it makes it more difficult for a thief "hot wire" the vehicle and start it.
