The keys themselves were just metal and had grooves that corresponded to the internal components of the ignition cylinder. As technology advanced the number of car makers began to mix physical and electronic protocols in order to prevent theft. These key systems are known as transponder keys or chip keys, and are designed to make it more difficult for thieves to start the vehicle. The key chips come with a unique serial code which transmits a signal to the receiver in your car. The signal is then compared to an identifier in the computer of the car when it is received. If the codes are compatible, then your car will start. If the codes aren't compatible, your car won't even start.

The energy is absorbed by the chip, which then transmits a radio frequency signal with an identification code that matches with the unique digital serial number of the car's computer system. This prevents unauthorised attempts to start the car, as only the correct key will be able to start the car. The technology is believed to be more secure than traditional car keys because it makes it more difficult for thieves to hot wire the vehicle and start it.
