How do you program a key
The majority of cars had basic key systems up until the turn of 21st century. The keys themselves were just metal and featured grooves that were connected to the internal components of the ignition cylinder. As technology advanced, more and more car makers began to combine physical and electronic protocols to avoid theft. These key systems, also known as transponder keys or chips keys, are designed to make it difficult for thieves to open a vehicle.
The key chips that are in the keys have a unique serial number, which transmits an electronic signal to the receiver inside your car. When the signal is received, it compares it to an existing code in the car's computer. If the codes match, your car will start. If not, it won't start at all. This is why you should keep an extra car key particularly if your system is transponder-based.

This energy is absorbed into the chip and it transmits an audio frequency signal that contains an identification code that is matched with the unique serial number in the car's computer system. This prevents unauthorized attempts to begin the car, as only right keys can be used.
This technology is believed to be more secure than conventional car keys because it makes it much more difficult for thieves to "hot wire" a vehicle and get it started. But it's not foolproof, and thieves have discovered ways to deceive and defy the system - which means that even cars equipped that have transponder keys aren't safe from theft.
