The majority of cars had basic key systems prior to the turn of the 21st century. Keys were made from metal and had grooves to correspond with the internal parts of the ignition cylinder. As technology improved the number of car makers began to mix physical and electronic protocols in order to prevent theft. These key systems are known as transponder keys or chip keys, and they're designed to make it difficult for thieves to open the vehicle. The key chips have an unique serial number which transmits a signal to the receiver in your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes are identical, your car will begin to start. If the codes aren't compatible, your car won't even start. This is one of the primary reasons you should keep a spare key on your vehicle, particularly when you use transponder-based systems.

This prevents any attempts by anyone else to start the car since only proper keys will be able to do so. The technology is believed 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.
