How do you program the key
The majority of cars had basic key systems up until the turn of the 21st century. Keys themselves were metal and featured grooves that matched the internal components of the ignition cylinder. As technology improved, more and more automobile makers began to mix electronic and physical protocols to stop theft. These key systems, also known as transponder keys or chips keys are designed to make it more difficult for thieves to steal the vehicle.
The key chips that are in the keys have a unique serial number, which transmits a signal to the receiver inside your car. When the signal is received it is compared to an existing code in the car's computer. If the codes are identical, your car will begin. If the codes aren't compatible, your vehicle won't start at all. This is why it is important to keep an extra car key especially if your system is based on transponders.

This energy is absorbed by the chip, which then transmits the radio frequency signal, which includes an identification code that matches with the unique digital serial number that is stored in the car's computer system. This will prevent any unauthorized attempts to start the car as only the correct key will be able to start the car.
The technology is believed to be more secure than a traditional car key, as it makes it more difficult for a criminal to "hot wire" the vehicle and then start it. However, it's not foolproof and thieves have discovered ways to deceive and defeat the system - so that even cars with transponder keys are not immune from theft.
