The keys themselves were just metal with grooves that matched the internal components of the ignition cylinder. As time passed and technology improved, more and more car manufacturers began blending 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 start the vehicle.
The key chips in the keys have a unique serial number that transmits an electronic signal to the receiver inside of your car. The signal is then compared to the computer of the car when it is received. If the codes are identical, your car will begin. If not, it won't start at all. This is why it is important to keep a spare car key, especially if the system is transponder-based.

In addition, the newest models are cloud-based and allow for remote management and configuration.
The majority of modern cars are equipped with an entry system that is keyless. To make this work it emits radio signals that are picked up by a special key fob. The signals are then compared to the correct code stored in the car's computer, and when everything is in order the car will be able to unlock.

This energy is absorbed by the chip and it transmits the radio frequency signal, which includes an identification code that corresponds up to the unique digital serial number in the car's computer system. This helps prevent an unauthorized attempt to start the car as only the correct key will be able to perform the task.
The technology is believed to be more secure than a traditional car key since it makes it difficult for thieves to "hot wire" the vehicle to start it. It's not foolproof and thieves have discovered ways of tricking and defeating the system. Therefore, even vehicles with a transponder key are not immune to theft.
