How to program a Key
Most cars had basic key systems up until the turn of the 21st century. The keys were made of metal and incorporated grooves to match the internal components of the ignition cylinder. As technology improved, more and more car manufacturers began to combine physical and electronic protocols to avoid theft. These key systems are known as transponder keys or chip keys, and are designed to make it difficult for thieves to open the vehicle.
The key chips that are in the keys have a specific serial number that transmits a signal to the receiver inside your car. When the signal is received it compares it with an existing code in the car's computer. If the codes match, then your car will start. If the codes aren't compatible, your car won't even start. This is why it is important to keep an extra car key especially if your system is based on transponders.
