How to program a Key
The majority of cars had basic key systems until the turn of the 21st century. The keys themselves were metal with grooves that corresponded to the internal components of the ignition cylinder. As time went on and technology advanced as it did, automobile manufacturers began blending electronic and physical protocols to prevent theft. Key systems, also known as transponder keys or chips keys, are designed to make it difficult for thieves to open the vehicle.
The key chips have an unique serial number that sends a message to the receiver inside your car. The signal is then compared to a code in the car's computer when it is received. If the codes match then your car will begin. If not, it will not start at all. This is why it is important to keep an extra car key especially if your system is transponder-based.
