As time went on and technology improved as it did, car manufacturers began blending electronic and physical protocols to prevent theft. These key systems are referred to as transponder keys or chip keys and they're designed to make it harder for thieves to start the vehicle.

The key chips that are in the keys have a specific serial number, which transmits an electronic signal to the receiver in your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes match, the car will start. If not, it won't start at all.
