The keys themselves were just metal and featured grooves that were connected to the internal parts of the ignition cylinder. As technology improved, more and more automobile manufacturers began to combine physical and electronic protocols to avoid theft. These key systems are called transponder keys or chip keys, and are designed to make it harder for thieves to open the vehicle.

The key chips that are in the keys have a specific serial number that transmits signals to the receiver inside of your car. The signal is compared with the computer of the car when it is received. If the codes match, your car will begin to start. If the codes aren't compatible, your car won't even start. This is why it is important to keep an extra car key especially if your system is based on transponders.

This code matches the unique serial numbers that are stored in the computer system of the car. This is to prevent unauthorized attempts to begin the car as only the right keys can be used.

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