However, as time progressed and technology improved, more and more automobile manufacturers began to combine physical and electronic protocols to prevent theft. These key systems are known as transponder keys or chip keys, and they're designed to make it harder for thieves to start the vehicle.

The key chips have an unique serial number that sends a message to the receiver in your car. The signal is compared with the computer of the car key programer when it is received.
