How to Program a Key

The majority of cars had basic keys systems prior to the turn of the 21st century. The keys themselves were just metal and had grooves that matched the internal parts of the ignition cylinder. As technology advanced, more and more car manufacturers began to combine physical and electronic protocols to avoid theft. These key systems are referred to as transponder key programmer keys or chip keys and they're designed to make it more difficult for thieves to get into the vehicle.

The key chips come with unique serial codes that sends a message to the receiver in your car. The signal is compared with the car's computer when it is received. If the codes are similar the car will begin to begin to start. If the codes aren't compatible, your car won't even start. This is one of the main reasons why you should always keep a spare key for your car, especially in the case of a transponder-based system.
