However, as time progressed and technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems are called transponder keys or chip keys, and they're designed to make it difficult for thieves to open the vehicle.

The key chips contain an unique serial number which transmits a signal to the receiver in your car. When the signal is received it is compared to a code stored in the car's computer. If the codes match, the car will start. If not, it will not start at all. This is why it is important to keep an extra car key especially if your system is transponder-based.
