How do you program a key?
Before the turn of the 21st century most cars used basic key systems. The keys were made of metal and incorporated grooves to correspond to the internal parts in the ignition cylinder. However, as time progressed and technology advanced, more and more automobile manufacturers began to combine physical and electronic protocols to protect against theft. Key systems like these are also referred to as transponder keys or chips keys are designed to make it more difficult for thieves to open a vehicle.
The key chips in the keys have a specific serial number that transmits an electronic signal to the receiver in your car. The signal is compared with an identifier in the computer of the car when it is received. If the codes are compatible, then the car will 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 based on transponders.

The energy is absorbed by the chip and it transmits the radio frequency signal, which includes an identification code that corresponds with the unique digital serial number that is stored in the car's computer system. This helps prevent unauthorized attempts to start the car, as only the correct key will be able to start the car.
This type of technology is thought to be more secure than a traditional car key since it makes it harder for a criminal to "hot wire" the vehicle to start it.
