As technology improved, more and more automobile makers began to combine electronic and physical protocols to stop theft. These key systems are called transponder keys or chip keys and are designed to make it harder for thieves to open the vehicle.

The key chips come with unique serial codes that sends a message to the receiver in your car. The signal is compared to an identifier in the car's computer when it is received. If the codes match, then your car will begin to start.

The chip absorbs the energy and then transmits a radio frequency signal that includes an identification code. This code matches the unique digital serial numbers of the computer system of the car. This stops unauthorised attempts to start the car as only the proper keys will be able to do so.

The technology is believed to be more secure than a traditional car key because it makes it difficult for a thief "hot wire" the vehicle to start it.
