As technology advanced, more and more automobile manufacturers began to combine physical and electronic protocols to avoid theft. These key systems also known as transponder keys or chips keys, are designed to make it more difficult for thieves to open the vehicle.

The key chips in the keys have a unique serial number, which transmits an electronic signal to the receiver inside of 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 compatible, then the car will start. If not, it won't start at all. This is one of the primary reasons why you should always keep a spare key on your car, especially when you use a transponder-based system.
