How do you program a key?

However, as time progressed and technology advanced and improved, car manufacturers began blending electronic and physical protocols to prevent theft. These key systems are known as transponder keys or chip keys and are designed to make it more difficult for thieves to open the vehicle.
The key chips come with an unique serial number that transmits a message to the receiver inside your car. When the signal is received it compares it with a code stored in the car's computer. If the codes match, your car will begin to start. If not, it won't start at all. This is the reason you should keep a spare car key, particularly if your system is transponder-based.

This energy is absorbed into the chip and it transmits the radio frequency signal, which includes an identification code that corresponds with the unique digital serial number of the car's computer system. This prevents unauthorised attempts to start the car, as only proper keys will be able to do so.
This technology is thought to be more secure than the traditional car key, as it makes it harder for a criminal to "hot wire" the vehicle and then start it.
