However, as time progressed and technology advanced and improved, car manufacturers began blending physical and electronic protocols to stop theft. These key systems are referred to as transponder keys or chip keys and are designed to make it more difficult for thieves to start the vehicle.

The key chips in the keys have a unique serial number that transmits an electronic signal to the receiver in your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes are similar, your car will begin to start. If the codes don't match, your vehicle won't start at all. This is why you should keep a spare car key, especially if the system is transponder-based.
