As time went on and technology improved as it did, 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 they're designed to make it more difficult for thieves to open the vehicle.

The key chips inside the keys have a unique serial number that sends an electronic 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 match, the car will start. If not, it will not start at all. This is one of the primary reasons you should keep a spare key on your vehicle, especially when you use a transponder-based system.

This energy is absorbed into the chip and sends back a radio frequency signal with an identification code that is matched with the unique digital serial number that is stored in the car key reprogrammed's computer system. This is to prevent unauthorized attempts to begin the car since only correct keys will be able.

The technology is believed to be more secure than traditional car keys because it makes it harder for a thief to "hot wire" an automobile and start it.
