As time passed and technology improved and improved, automobile manufacturers began blending electronic and physical protocols to prevent theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it difficult for thieves to get into the vehicle.
The key chips contain unique serial codes which transmits a signal to the receiver in your car. The signal is then compared to a code in the car's computer when it is received. If the codes are compatible, then the car will start. If the codes don't match, then your vehicle won't start at all.
