How do you program a key?

The majority of cars had basic key systems prior to the turn of 21st century. Keys themselves were metal with grooves that were connected to the internal parts of the ignition cylinder. As technology advanced the number of car makers began to mix electronic and physical protocols in order to prevent theft. These key systems are called transponder key programmer keys or chip keys and are designed to make it more difficult for thieves to start the vehicle.

The key chips inside the keys have a specific serial number, which transmits an electronic signal to the receiver inside of your car. The signal is then compared to an identifier in the car's computer when it is received. If the codes are identical then your car will begin to start. If not, it won't start at all. This is one of the main reasons to keep a spare key in your vehicle, particularly if you have a transponder-based system.

When the time has passed you can take out the key and check if the security light on your dashboard went out. If not then you'll have repeat the process the third time.

The most recent models also permit remote management and configuration and are cloud-based.

Modern cars are equipped with keyless entry systems. To enable this feature the car emits radio signals which are picked up by a specific key fob.

The energy is absorbed by the chip, which then transmits an audio frequency signal that contains an identification code that is matched with the unique serial number in the car's computer system. This stops any attempts by anyone else to start the car as only the correct keys will be able.

The technology is believed 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.
