As technology improved, more and more automobile makers began to mix electronic and physical protocols in order to prevent theft. Key systems also known as transponder keys or chips keys, are designed to make it harder for thieves to open an automobile.
The key chips in the keys have a unique serial number, which transmits signals to the receiver inside your car. The signal is compared with a code in the computer of the car when it is received. If the codes match, the car will start. If not, it will not start at all.
