The keys themselves were metal and featured grooves that corresponded to the internal components of the ignition cylinder. As time passed and technology advanced as it did, car manufacturers began blending physical and electronic protocols to protect against theft. Key systems are also referred to as transponder keys or chips keys are designed to make it difficult for thieves to start the vehicle.
The key chips that are in the keys have a unique serial number, which transmits a signal to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes match, your car will begin to start. If the codes don't match, your car will not even start. This is the reason you should keep an extra car key especially if your system is transponder-based.

This stops any attempts by anyone else to start the car as only the proper keys will be able to do so.
The technology is believed to be more secure than the traditional car key since it makes it more difficult for thieves to "hot wire" the vehicle to start it.
