The keys were made of metal and incorporated grooves to correspond to the internal parts of the ignition cylinder. As time passed and technology improved, more and more automobile manufacturers began to combine electronic and physical protocols to protect against theft. Key systems like these, also known as transponder keys or chips keys are designed to make it difficult for thieves to open an automobile.

The key chips have unique serial codes that transmits a message to the receiver in your car. When the signal is received it compares it with an existing code in the car's computer. If the codes are compatible, then your car will start. If the codes aren't compatible, your car will not even start. This is one of the main reasons you should keep a spare key programmers for your vehicle, particularly if you have transponder-based systems.

The chip absorbs this energy, and then transmits a radiofrequency signal that contains an identification code. This code matches the unique serial numbers in the computer of the car. This is to prevent any attempts by anyone else to start the car since only right keys can be used.

The technology is believed to be more secure than a traditional car key since it makes it harder for thieves to "hot wire" the vehicle and then start it.
