The majority of cars had basic key systems until the turn of 21st century. Keys themselves were metal and had grooves that were connected to the internal components of the ignition cylinder. However, as time progressed and technology improved, more and more automobile manufacturers began blending physical and electronic protocols to prevent theft. These key systems are called 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 unique serial number, which transmits an electronic signal to the receiver inside your car. The signal is then compared to the car's computer when it is received. If the codes are compatible, then the car will start. If the codes aren't compatible, your vehicle won't start at all. This is why you should keep an extra car key, especially if your system is based on transponders.

The energy is absorbed by the chip, which then transmits the radio frequency signal, which includes an identification code that is matched with the unique digital serial number in the car's computer system. This prevents an unauthorized attempt to start the car because only a valid key can start the car.
The technology is believed to be more secure than traditional car keys because it makes it difficult for thieves to "hot wire" a vehicle and get it started. It's not foolproof and thieves have found ways to trick and defeat the system. So even cars with transponder keys aren't immune to theft.
