The keys themselves were just metal and had grooves that corresponded to the internal parts of the ignition cylinder. As time passed and technology advanced and improved, automobile manufacturers began to combine electronic and physical protocols to stop 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 inside the keys have a specific serial number that transmits signals to the receiver inside of your car. When the signal is received it is compared to an existing code in the car's computer. If the codes are compatible, then your car will start. If the codes don't match, your vehicle won't start at all.

This energy is absorbed into the chip, which then transmits a radio frequency signal with an identification code that corresponds up to the unique serial number in the car's computer system. This is to prevent unauthorised attempts to start the car as only the correct keys will be able. It is believed that this technology will be more secure than traditional keys for cars because it makes it harder for a thief to "hot wire" the vehicle and start it.
