As time went on and technology advanced and improved, automobile manufacturers began to combine physical and electronic protocols to prevent theft. These key systems are known as transponder keys or chip keys, and are designed to make it difficult for thieves to open the vehicle.

The chip absorbs this energy and then transmits a radio frequency signal that contains an identification code. This code matches the unique serial numbers in the computer of the car. This will prevent any unauthorized 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 car keys because it makes it much difficult for thieves to "hot wire" the vehicle and start it.
