The keys themselves were metal and had grooves that corresponded to the internal parts of the ignition cylinder. As technology improved, more and more car manufacturers began to combine physical and electronic protocols to stop theft. These key systems are called transponder keys or chip keys, and are designed to make it more difficult for thieves to get into the vehicle.
The key chips inside the keys have a unique serial number that sends signals to the receiver inside 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 the car will start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key for your vehicle, particularly in the case of an electronic transponder.

The energy is absorbed by the chip and sends back an audio frequency signal that contains an identification code that is matched up to the unique digital serial number that is stored in the car's computer system. This helps prevent unauthorized attempts to start the car, as only the correct key will be able to do so.
This technology is believed to be more secure than conventional car keys because it makes it much more difficult for thieves to "hot wire" an automobile and get it started.
