As technology advanced the number of car manufacturers began to combine electronic and physical protocols to stop theft. These key systems are referred to as transponder keys or chip keys, and are designed to make it more difficult for thieves to open the vehicle.

The key programmers chips that are in the keys have a specific serial number that transmits a signal to the receiver inside your car. When the signal is received it is compared to an existing code in the car's computer. If the codes are similar then your car will start. If not, it won't start at all. This is why it is important to keep a spare car key, particularly if your system is transponder-based.

If you want to learn how to program keys, you'll need some specific equipment. You'll also require the blank key that matches your specific model and make.

This energy is absorbed by the chip and sends back an audio frequency signal that contains an identification code that is matched with the unique digital serial number that is stored in the car's computer system. This is to prevent unauthorized attempts to begin the car, as only correct keys will be able.

This technology is believed to be more secure than conventional car keys because it makes it much difficult for thieves to "hot wire" a vehicle and start it.
