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

The key chips inside the keys have a specific serial number, which transmits a signal to the receiver in your car.

This is one of the main reasons you should keep a spare key in your car, especially in the case of transponder-based systems.

This prevents unauthorized attempts to begin the car, as only correct keys will be able.

It is believed that this technology will be more secure than traditional car keys because it makes it much more difficult for thieves to "hot wire" the vehicle and get it started.
