How do you program a key?

Before the turn of the 21st century, most cars used basic key systems. The keys themselves were metal with grooves that corresponded to the internal parts of the ignition cylinder. As technology improved, more and more car manufacturers began to combine physical and electronic protocols in order to prevent theft. These key systems are referred to as transponder keys or chip keys, and they're designed to make it harder for thieves to get into the vehicle.

The key chips come with unique serial codes that transmits a message to the receiver inside your car. The signal is compared with a code in the car's computer when it is received. If the codes are compatible, then your car will start. If not, it won't start at all. This is one of the primary reasons you should keep a spare key on your vehicle, particularly when you use transponder-based systems.

This will prevent any an unauthorized attempt to start the car, as only the correct key will be able to start the car.

This technology is believed to be more secure than traditional keys for cars because it makes it more difficult for thieves to "hot wire" an automobile and start it.
