As technology advanced, more and more car manufacturers began to combine electronic and physical protocols to avoid theft. These key systems, also known as transponder keys or chips keys, are designed to make it harder for thieves to steal a vehicle.

This helps prevent unauthorized attempts to start the car as only the correct key will be able to do so.

The technology is believed to be more secure than a traditional car key because it makes it more difficult for a thief "hot wire" the vehicle and then start it.
