Up until the turn of the 21st century, the majority of cars utilized basic key systems. The keys themselves were just metal with grooves that corresponded to the internal components of the ignition cylinder. As technology advanced, more and more car manufacturers began to combine electronic and physical protocols to stop theft. These key systems are known as transponder keys or chip keys and are designed to make it more difficult for thieves to open the vehicle.
The key chips inside the keys have a specific serial number that sends signals to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes are compatible, then your car will begin to 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 car, especially in the case of an electronic transponder.

The system can also detect and block stolen or lost cards. The latest models also support remote management and configuration as well as are cloud-based.
Most modern cars are equipped with an entry system that is keyless. To accomplish this the car emits radio signals that are picked up by a specific key fob. These signals are then compared to the correct code in the car's computer and if everything is in order, the car will unlock. If the signals do not match then the car won't start. If your key fob isn't already programmed, you can follow a few steps to program it.

This energy is absorbed by the chip and it transmits the radio frequency signal, which includes an identification code that matches up to the unique serial number of the car's computer system. This prevents unauthorised attempts to start the car since only correct keys will be able.
This type of technology is thought to be more secure than a conventional car key since it makes it difficult for a thief "hot wire" the vehicle to start it. It's not foolproof, and thieves have discovered ways of tricking and defeating the system. So even cars equipped with transponder keys aren't protected from theft.

If the codes are the same the car will begin. If the codes don't match, the car will not start or remain dead.
