As technology improved, more and more car makers began to mix physical and electronic protocols in order to prevent theft. These key systems, also known as transponder keys or chips keys are designed to make it harder for thieves to start a vehicle.
The key chips in the keys have a unique serial number that transmits signals to the receiver in your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are compatible, then your car will start. If not, it will not start at all. This is why you should keep an extra car key especially if your system is transponder-based.

This energy is absorbed into the chip and sends back the radio frequency signal, which includes an identification code that corresponds with the unique serial number in the car's computer system. This will prevent any unauthorized attempts to start the car as only the correct key can do so.
This technology is thought to be more secure than a conventional car key since it makes it more difficult for a criminal to "hot wire" the vehicle to start it. It's not foolproof, and thieves have found ways to trick and defeat the system. So even cars with transponder key are not immune to theft.
