As technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols to avoid theft. These key systems are called transponder keys or chip keys, and they're designed to make it difficult for thieves to start the vehicle.
The key chips inside the keys have a specific serial number that transmits a signal to the receiver in your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes are identical, your car will start. If the codes aren't compatible, your car will not even start. This is one of the main reasons you should keep a spare key for your vehicle, especially when you use a transponder-based system.

This helps prevent an unauthorized attempt to start the car, because only a valid key will be able to start the car.
