As time went on and technology improved as it did, automobile manufacturers began to combine electronic and physical protocols to protect against theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it difficult for thieves to start the vehicle.

The key chips contain unique serial codes that transmits a message to the receiver inside your car. The signal is then compared to a code in the computer of the car when it is received. If the codes match then your car will start. If not, it will not start at all. This is one of the main reasons to keep a spare key in your vehicle, especially in the case of a transponder-based system.

This energy is absorbed into the chip and it transmits the radio frequency signal, which includes 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 unauthorised attempts to start the car because only a valid key can perform the task.

This technology is believed to be more secure than conventional car keys because it makes it difficult for thieves to "hot wire" a vehicle and start it.
