The keys themselves were just metal and featured grooves that corresponded to the internal components 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 known as transponder keys or chip keys and they're designed to make it more difficult for thieves to get into the vehicle.

The key chips contain unique serial codes that sends a message to the receiver inside your car. The signal is compared with the car's computer when it is received. If the codes match, the car will start. If not, Program a Car Key it won't start at all.

This energy is absorbed into the chip, which then transmits a radio frequency signal with an identification code that is matched with the unique serial number of the car's computer system. This stops unauthorised attempts to start the car since only right keys can be used.

This technology is thought to be more secure than the traditional car key, as it makes it difficult for a criminal to "hot wire" the vehicle to start it.
