Prior to the beginning of the 21st century, most cars used basic key systems. Keys themselves were metal and had grooves that matched the internal parts of the ignition cylinder. As technology improved the number of car manufacturers began to combine physical and electronic protocols in order to prevent theft. Key systems like these also known as transponder keys or chips keys, are designed to make it harder for thieves to open the vehicle.
The key chips inside the keys have a specific serial number that sends signals to the receiver in your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes are compatible, then the car will start. If the codes don't match, then your car won't even start. This is why you should keep an extra car key particularly if your system is based on transponders.
If you're looking to learn how to program keys, you'll need certain equipment. You'll also require a blank key that matches your specific model and make.

The chip absorbs the energy and then transmits a radiofrequency signal that includes an identification code. The code is matched to the unique digital serial numbers in the computer system of the car. This is to prevent any attempts by anyone else to start the car, as only proper keys will be able to do so.
This technology is thought to be more secure than a traditional car key because it makes it difficult for thieves to "hot wire" the vehicle to start it.
