The keys themselves were just metal and had grooves that were connected to the internal parts of the ignition cylinder. As technology improved, more and more car makers began to mix physical and electronic protocols to avoid theft. These key systems are referred to as transponder keys or chip keys, and they're designed to make it harder for thieves to open the vehicle.

The key chips have an unique serial number which transmits a signal to the receiver in your car. The signal is compared to a code in the car's computer when it is received. If the codes are identical the car will begin to begin to start. If the codes don't match, then your vehicle won't start at all. This is why you should keep an extra car key especially if the system is based on transponders.

This helps prevent unauthorized attempts to start the car as only the correct key will be able to perform the task.

It is believed that this technology will be more secure than traditional car keys because it makes it much harder for a thief to "hot wire" the vehicle and start it.
