As technology advanced, more and more car makers began to mix electronic and physical protocols to stop theft. Key systems like these, also known as transponder keys or chips keys, are designed to make it difficult for thieves to start a vehicle.

The key chips have an unique serial number which transmits a signal to the receiver inside your car. When the signal is received it compares it with the code that is stored in the car's computer.
