However, as time progressed and technology improved and improved, car manufacturers began blending electronic and physical protocols to stop theft. These key systems are known as transponder keys or chip keys and are designed to make it difficult for thieves to open the vehicle.
The key chips inside the keys have a specific serial number that sends an electronic signal to the receiver in your car. When the signal is received it is compared to a code stored in the car's computer. If the codes are similar then your car will begin to start. If not, it will not start at all. This is one of the main reasons to keep a spare key for your car, especially in the case of an electronic transponder.
