Prior to the beginning of the 21st century the majority of cars had basic key systems. The keys were made of metal and featured grooves that correspond with the internal parts of the ignition cylinder. As time passed and technology advanced, more and more car manufacturers began blending electronic and physical 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 start the vehicle.

The key chips in the keys have a specific serial number that sends an electronic signal to the receiver inside of your car. The signal is then compared to an identifier in the computer of the car when it is received. If the codes match, then your car will begin to start.
