As technology advanced the number of car makers began to combine electronic and physical protocols to avoid theft. These key systems are called transponder keys or chip keys and they're designed to make it harder for thieves to open the vehicle.

The key chips have a unique serial code that sends a message to the receiver inside your car. The signal is compared to the computer of the car when it is received. If the codes are similar the car will begin to begin. If not, it won't start at all. This is why you should keep an extra car key, especially if your system is transponder-based.

This 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 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.

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