How to Program a Key Up until the turn of the 21st century, most cars used basic key systems. The keys themselves were just metal and featured grooves that matched the internal components of the ignition cylinder. However, as time progressed and technology improved and improved, automobile manufacturers began to combine electronic and physical protocols to stop theft. These key systems are known as transponder keys or chip keys, and are designed to make it difficult for thieves to start the vehicle. The key chips that are in the keys have a specific serial number that transmits a signal to the receiver in your car. The signal is compared with the computer of the car when it is received. If the codes match, then the car will start. If not, it won't start at all. This is one of the main reasons you should keep a spare key in your vehicle, particularly when you use transponder-based systems.

The code is matched to the unique serial numbers that are stored in the computer of the car. This is to prevent unauthorised attempts to start the car as only the correct keys will be able. It is believed that this technology will be more secure than traditional car keys because it makes it much more difficult for thieves to “hot wire” an automobile and get it started.
