As technology advanced, more and more automobile manufacturers began to combine electronic and physical protocols to stop theft. Key systems like these also known as transponder keys or chips keys, are designed to make it more difficult for thieves to open the vehicle.

The key chips inside the keys have a unique serial number, which transmits signals to the receiver inside of your car. When the signal is received it is compared to the code that is stored in the car's computer. If the codes are identical the programmable car keys will begin to start. If the codes don't match, then your car will not even start. This is why you should keep an extra car key, especially if your system is transponder-based.

You'll require special equipment to be able to program keys. You'll also need to purchase the blank key for your specific model and make.

The energy is absorbed by the chip, which then transmits the radio frequency signal, which includes an identification code that is matched with the unique digital serial number in the car's computer system. This stops unauthorised attempts to start the car keys cut and programmed, as only right keys can be used.

This technology is thought to be more secure than a traditional car key, as it makes it harder for a thief "hot wire" the vehicle and start it. However, it's not foolproof and thieves have found ways to trick and defy the system - so that even vehicles with transponder keys are not protected from theft.
