How do you program the key
The majority of cars had basic keys systems up until the turn of the 21st century. Keys were made of metal and incorporated grooves to correspond to the internal parts of the ignition cylinder. As time passed and technology improved, more and more automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems are called transponder keys or chip keys, and are designed to make it more difficult for thieves to get into the vehicle.
The key chips contain an unique serial number that transmits a message to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes match the car will begin to begin to start. 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.
