How do you program a key
Prior to the beginning of the 21st century most cars used basic key systems. The keys themselves were metal and had grooves that were connected to the internal parts of the ignition cylinder. However, as time progressed and technology improved and improved, automobile manufacturers began to combine electronic and physical protocols to protect against theft. These key systems are known as transponder keys or chip keys, and are designed to make it harder for thieves to open the vehicle.
The key chips come with unique serial codes which transmits a signal to the receiver inside your car. When the signal is received it compares it with the code that is stored in the car's computer. If the codes are compatible, then your car will begin to start. If the codes don't match, your car won't even start. This is one of the main reasons you should keep a spare key for your car, especially in the case of transponder-based systems.
