How do you program a key?
Most cars had basic key systems up until the turn of the 21st century. Keys were made of metal and featured grooves that match the internal components of the ignition cylinder. As technology advanced, more and more automobile makers began to combine physical and electronic 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 get into the vehicle.
The key chips in the keys have a specific serial number that sends an electronic signal to the receiver inside of your car. The signal is compared with an identifier in the computer of the car when it is received. If the codes match, then your car will begin to 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.

The chip absorbs this energy, and then transmits a radiofrequency signal that contains an identification code. This code matches the unique serial numbers in the car's computers. This helps prevent unauthorized attempts to start the car, since only the right key will be able to do so.
This technology is believed to be more secure than traditional keys for cars because it makes it much harder for a thief to "hot wire" the vehicle and start it.
