As time passed and technology improved as it did, automobile manufacturers began to combine electronic and physical protocols to prevent theft. These key systems are also referred to as transponder keys or chips keys are designed to make it harder for thieves to open an automobile.
The key chips have a unique serial code that sends a message to the receiver inside your car. When the signal is received, it compares it to the code that is stored in the car's computer. If the codes are similar, your car will start. If not, it will not start at all. This is one of the main reasons you should keep a spare key for your vehicle, particularly if you have an electronic transponder.
If you want to learn how to program keys, you'll require some special equipment. You'll need a blank key that matches your car model and make.

This energy is absorbed into the chip and it transmits the radio frequency signal, which includes an identification code that corresponds up to the unique digital serial number that is stored in the car's computer system. This stops any attempts by anyone else to start the car since only correct keys will be able.
This technology is believed to be more secure than conventional car keys because it makes it difficult for thieves to "hot wire" the vehicle and start it.
