The majority of cars had basic keys systems up until the turn of the 21st century. The keys were made of metal and incorporated grooves to correspond to the internal parts in the ignition cylinder. As time went on and technology improved, more and more automobile manufacturers began blending physical and electronic protocols to protect against theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it more difficult for thieves to open the vehicle.
The key chips in the keys have a specific serial number that transmits a signal 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 identical then your car will begin to start. If not, it will not start at all. This is one of the primary reasons to keep a spare key in your vehicle, particularly when you use transponder-based systems.

This energy is absorbed by the chip and sends back a radio frequency signal with an identification code that corresponds with the unique serial number in the car's computer system. This will prevent any an unauthorized attempt to start the car as only the correct key can start the car.
This technology is thought to be more secure than the traditional car key since it makes it difficult for a thief "hot wire" the vehicle and then start it.
