However, as time progressed and technology advanced and improved, car manufacturers began blending physical and electronic protocols to stop theft. These key systems also known as transponder keys or chips keys are designed to make it more difficult for thieves to open an automobile.

The key chips that are in the keys have a 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 match the car will begin to begin to start. If not, it won't start at all. This is one of the main reasons to keep a spare key for your car, especially when you use transponder-based systems.

This stops unauthorized attempts to begin the car as only the proper keys will be able to do so.

The technology is believed to be more secure than traditional keys for cars because it makes it much difficult for thieves to "hot wire" a vehicle and get it started.
