As time went on and technology improved and improved, automobile manufacturers began to combine physical and electronic protocols to prevent theft. These key systems are known as transponder keys or chip keys and are designed to make it difficult for thieves to open the vehicle. The key chips contain unique serial codes which 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 your car will begin to start. If the codes aren't compatible, your vehicle won't start at all.

This prevents unauthorized attempts to begin the car since only correct keys will be able. This type of technology is thought to be more secure than a conventional car key because it makes it harder for thieves to “hot wire” the vehicle and start it.
