As time passed and technology advanced as it did, automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems are known as transponder keys or chip keys, and are designed to make it harder for thieves to open the vehicle.

The key chips contain an unique serial number that transmits a message to the receiver inside your car. The signal is then compared to the car's computer when it is received. If the codes are compatible, then your car will begin to start. If not, it won't start at all. This is one of the main reasons why you should always keep a spare key in your car, especially when you use an electronic transponder.
