As technology advanced the number of car makers began to combine physical and electronic protocols to stop theft. Key systems also known as transponder keys or chips keys, are designed to make it difficult for thieves to open the vehicle.

The key chips contain an unique serial number which transmits a signal to the receiver inside your car. When the signal is received, it compares it to a code stored in the car's computer. If the codes are identical then your car will begin to start. If the codes aren't compatible, your car will not even start. This is why you should keep an extra car key, especially if your system is based on transponders.

You'll require special equipment to be able to program keys. You'll need a blank key that is compatible with your car model and make.

The energy is absorbed by the chip, which then transmits an audio frequency signal that contains an identification code that is matched with the unique digital serial number in the car's computer system. This will prevent any an unauthorized attempt to start the car as only the correct key can start the car.

This type of technology is thought to be more secure than a conventional car key, as it makes it more difficult for a criminal to "hot wire" the vehicle and then start it.
