As technology advanced, more and more automobile makers began to mix electronic and physical protocols in order to prevent theft. These key systems are called transponder keys or chip keys, and are designed to make it more difficult for thieves to open the vehicle.
The key chips inside the keys have a unique serial number that sends a signal to the receiver in your car. The signal is compared with a code in the computer of the car when it is received.
