Keys themselves were metal and featured grooves that matched the internal components of the ignition cylinder. As technology advanced, more and more car makers began to combine physical and electronic protocols in order to prevent theft. These key systems are referred to as transponder keys or chip keys, and they're designed to make it harder for thieves to get into the vehicle.

The key chips come with a unique serial code which transmits a signal to the receiver in your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are identical then your car will begin. If the codes aren't compatible, your vehicle won't start at all. This is one of the main reasons to keep a spare key on your vehicle, particularly in the case of a transponder-based system.

The energy is absorbed by the chip and sends back an audio frequency signal that contains an identification code that matches with the unique digital serial number of the car's computer system. This will prevent any unauthorised attempts to start the car, as only the correct key will be able to perform the task.

This technology is believed to be more secure than traditional keys for cars because it makes it much more difficult for thieves to "hot wire" the vehicle and start it.
