Before the turn of the 21st century the majority of cars utilized basic key systems. The keys were made of metal and featured grooves that match the internal components of the ignition cylinder. As time passed and technology improved as it did, automobile manufacturers began blending physical and electronic protocols to prevent theft. These key systems are known as transponder keys or chip keys and they're designed to make it harder for thieves to start the vehicle.

The key chips have unique serial codes that transmits a message to the receiver inside your car. The signal is compared to an identifier in the computer of the car when it is received. If the codes match, then the car will start. If the codes don't match, your car will not even start. This is why it is important to keep a spare car key, particularly if your system is transponder-based.

If you want to learn how to program a key, you'll need some specific equipment. You'll need a blank key that matches your car model and make.

This is to prevent unauthorized attempts to begin the car as only the proper keys will be able to do so.

This type of technology is thought to be more secure than a conventional car key since it makes it harder for a thief "hot wire" the vehicle and start it.
