How do you program a key?
Before the turn 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 advanced, more and more car manufacturers began to combine electronic and physical protocols in order to prevent theft. Key systems also known as transponder keys or chips keys, are designed to make it harder for thieves to start the vehicle.
The key chips have a unique serial code that transmits a message 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 your car will begin to start. If not, it won't start at all. This is the reason you should keep an extra car key, especially if the system is transponder-based.

The chip absorbs this energy, and then transmits a radiofrequency signal that includes an identification code. The code is matched to the unique digital serial numbers in the car's computers. This is to prevent unauthorized attempts to begin the car as only the correct keys will be able.
This type of technology is thought to be more secure than the traditional car key because it makes it harder for a criminal to "hot wire" the vehicle and start it.
