How to Program a Key
Before the turn of the 21st century, most cars used basic key systems. Keys were made from metal and had grooves to match the internal components of the ignition cylinder. As time passed and technology advanced as it did, automobile manufacturers began blending physical and electronic protocols to stop theft. These key systems are known as transponder keys or chip keys and they're designed to make it harder for thieves to open the vehicle.
The key chips come with unique serial codes which transmits a signal to the receiver in your car. The signal is compared with an identifier in the car's computer when it is received. If the codes match, your car will begin. If the codes don't match, your car will not even start. This is one of the primary reasons you should keep a spare key for your vehicle, particularly in the case of an electronic transponder.

This type of technology is thought to be more secure than the traditional car key, as it makes it difficult for a criminal to "hot wire" the vehicle and start it.
